Ultra-Processed Food and Dementia

Researchers are more and more concerned about an association between ultra-processed food and dementia. A new study found that when you consume more than 20% of you daily food intake as processed food, you can start developing cognitive decline. Eating just 2 cookies per day, which have about 100 calories, will lead to cognitive decline.

What is processed food?

Foods such as instant noodles, hot dogs and ice cream are not healthy. There is too much salt, sugar and unhealthy fat in them that undermine your health. If you consider breakfast granola as “healthy”, you’d better take a look at the ingredients: sugar is one of them! Frozen meals, sugary drinks, take-out pizzas, deep-fried chicken and French fries also belong to unhealthy foods. Unless you buy fresh ingredients and make your own Mediterranean-style meals, you will struggle staying healthy. Processed foods lead to weight gain, which is difficult to shed unless you give up processed food.

Processed food often contains flavorings, colorings or other additives. White bread and bakery products, fried snacks, crackers, cookies, ice cream, candy, cream cheese and processed cheese, soda and frozen meals fall into this category.

Conference in San Diego

At the 2022 Alzheimer’s Association International Conference in San Diego researchers revealed the results of a Brazilian study. 10,000 Brazilians were followed with dietary habits and intermittent cognitive tests for up to 10 years. In the beginning none of the participants had a cognitive deficit. The average age at the time of the beginning of the study was 51 years. When you eat more than 20 % ultra-processed food of your total calorie intake every day, cognitive decline is showing up on the cognitive tests. Specifically, patients who consumed more than 20% calories from ultra-processed food developed 28% faster decline in cognitive tests. They also developed 25% faster decline in executive functioning.

Comment from a co author

Co Author Dr. Claudia Suemoto, an assistant professor in the division of geriatrics at the University of São Paulo Medical School stated: “In Brazil, ultra-processed foods make up 25% to 30% of total calorie intake. We have McDonald’s, Burger King and we eat a lot of chocolate and white bread. It’s not very different, unfortunately, from many other Western countries”. She went on to say: “58% of the calories consumed by United States citizens, 56.8% of the calories consumed by British citizens, and 48% of the calories consumed by Canadians come from ultra-processed foods”. She expressed her concern that these statistics show that many more seniors than now will develop Alzheimer’s disease. In the Brazilian study researchers followed their subjects for up to 10 years. After decades of exposure to ultra-processed food the numbers of people with cognitive deficits and Alzheimer’s disease will be much higher.

Other means to prevent cognitive decline

A study showed that regular aerobic exercises (running, treadmill, walking) or stretching, balancing and range of motion exercises both prevented cognitive decline. The best is to build some form of exercise into your daily routine. This is particularly important for people who have desk jobs.

What are healthy foods to eat?

We need to eat more vegetables, fruit and cut out sugar, omit too many starchy foods, salt and unhealthy fats. So, how does that work? In the following I am giving examples of a healthy breakfast, lunch and dinner.

Breakfast

Start the day with fresh fruit, a bowl of rolled oats with milk or a milk alternative. Add a few almonds or chopped nuts or ground flaxseed. You could add raspberries, blackberries, strawberries or blueberries.

If you want a breakfast with egg, try an omelet with eggs or egg white with mushrooms, onions and chopped greens! No, it does not always have to be kale! Enjoy arugula or spinach. Add some salsa on the side.

For those who hate to prepare breakfast, take it easy: put 1/2 a banana, a cup of berries, 1 tablespoon almond butter and 3/4 cup of low-fat yoghurt into the blender. Blend at high speed. This takes less than 2 minutes. Enjoy! It does not get much easier than that.

Lunch

Assemble some mixed salad greens, 1 sliced tomato, 1 cup of sliced cucumber, half a sliced avocado and 1/2 shredded carrot on a plate or in a bowl. Add 2 slices of cheese or 2 tablespoons of crumbled feta cheese. Add one boiled and sliced egg or alternatively 4 slices of chicken breast. Make a dressing of 2 tablespoons of olive oil and 1 tablespoon of balsamic vinegar. You can prepare this easy lunch the evening before and take it to work.

If you want a warm lunch, cook a simple Italian-style vegetable soup. Sprinkle it with a tablespoon of grated parmigiano cheese and serve it with a slice of whole-grain bread. A vegetable chili is a good choice for a colder day. Have some fresh fruit for dessert.

Dinner

Make vegetables the main event. Do not have a huge steak with an afterthought of vegetables, but build a tasty meal around vegetables with a protein of your choice: lean meats, such as chicken breast, enjoy fish or other seafood or experiment with other protein sources, such as tofu. The latter works well in an Asian-style vegetable stir-fry. And otherwise: breaded and deep-fried chicken or battered fish are not healthy choices, even if you prepare the meal at home! Forget the breading and dip the meat into a tasty marinade instead! If you want to have a quick dessert, make a colorful fruit salad with a dollop of yoghurt on top. For all those who drool over a decadent dessert in a restaurant, go ahead and order that Tiramisu and share it with others of your party. But it should be an exception rather than a regular treat.

Conclusion

Researchers are more and more concerned about an association between ultra-processed food and dementia. A new study found that when you consume more than 20% of you daily food intake as processed food, you start developing cognitive decline. Eating just 2 cookies per day, which have about 100 calories, will lead to cognitive decline. It is fairly easy to cut out junk foods from your diet and to adopt healthy eating ha its.

Meal suggestions

Start the day with fresh fruit, a bowl of rolled oats with milk or milk alternative. Add a few almonds or chopped nuts or ground flaxseed. You could add raspberries, blackberries, strawberries blueberries. I sweeten everything with stevia extract and avoid sugar completely. For lunch you could have mixed salad greens with 2 slices of cheese or 2 tablespoons of crumbled feta cheese. Add one boiled and sliced egg or alternatively 4 slices of chicken breast. For dinner make vegetables the main event. Do not have a huge steak with an afterthought of vegetables, but build a tasty meal around vegetables with a protein of your choice: lean meats, such as chicken breast, enjoy fish or other seafood or experiment with other protein sources, such as tofu.

Final remark

You see, it is fairly easy to avoid ultra-processed foods that lead to cognitive decline. It involves a critical look at your current eating habits and very likely some cleaning-out of less than desirable foods from your pantry.

The Benefits Of Drinking Green Tea

Chances are you heard about the benefits of drinking green tea to reduce heart disease. But the polyphenols of green tea also prevent cancer, depression and cognitive decline.

Green tea lowers cardiovascular mortality

A study in the Chianti region of Tuscany, Italy consisted of 807 men and women aged 65 years and older. They had urine tests for metabolites of green tea in the beginning of the study. The study went on for 12 years. 274 participants died, which was 34% of the total study group. Tests measured the total urinary polyphenol (TUP) concentration in both groups, the survivors and the participants who died. Those participants whose TUP was in the highest tertile of the TUP values had the lowest all-cause mortality. And those participants whose TUP was in the lowest tertile had the highest all-cause mortality. 

High blood pressure and stroke

A Taiwanese study from 2004 examined the blood pressure of 1507 subjects. There were 711 men and 796 women with a recent diagnosis of  high blood pressure. The investigators looked at tea consumption (green tea and oolong tea) and blood pressure reduction. They found that those who drank 120 to 599 mL/day of green tea or oolong tea decreased their blood pressure by 46%. Those who drank more than 600 mL/day of green tea or oolong tea lowered their blood pressure by 65%.

Another meta-study involving 194,965 people and 4378 strokes found that there was a reduction of strokes with increasing tea consumption. Those who drank 3 or 4 cups of green tea or black tea per day were the experimental group. Researchers compared them  to the control group that drank less than one cup of tea per day. The experimental group had a 21% lower risk of getting a stroke than the control group.

Cancer prevention more with black tea than with green tea

A meta-analysis of 18 studies from China showed that green tea and black tea consumption was beneficial for prevention of cardiovascular disease and for cancer prevention. The highest consumption of green tea reduced cardiovascular mortality by 33%. The highest black tea consumption lowered mortality by 12%. Cancer mortality turned out to be different. Green tea did not produce a reduction in mortality, but black tea lowered it by 21%.

Another study, this one from Shanghai, China, points out that there are 15 polyphenols in green tea that likely work on different target areas of the body. They target 200 different genes in humans affecting diabetes, cancer, cardiovascular disease, neurodegenerative disease, muscular disease and inflammation.

Other cancers like prostate and breast cancer benefit from green tea

This study shows evidence that habitual green tea drinkers do prevent prostate cancer and breast cancer to a certain extent.

Another study investigates the effect of tea on health. One of the studies from the same authors have shown that the oxidative damage to cells from cigarette smoking can come out in a urine test. Those smokers who drank 4 cups of tea per day had a 31% decrease in their urinary biomarkers to indicate DNA damage. As DNA damage is often the first step in cancer development, these findings are important to note.

Cognitive effects of green tea consumption in dementia patients

A 2017 review of dietary supplements to improve cognitive impairment pointed out several supplements that will improve cognition. Green tea is one of them, but omega-3 fatty acids (EPA), and docosahexaenoic acid (DHA) are also useful supplements to restore neuronal functioning.

A 2017 study from Basel, Switzerland found that green tea improved memory, reduced anxiety and activated the working memory, which could be made visible on functional MRI scans. These researchers also pointed out that green tea has this effect as a whole, you cannot attribute it to a single constituent. Separate tests of  caffeine or L-Theanine  showed that the beneficial effect was smaller than when green tea as a whole was tested.

2016 study on severe Alzheimer’s patients

This 2016 Iranian study looked at 30 patients with severe Alzheimer’s disease. A baseline assessment was first, and 2 months after taking 4 green tea pills daily another assessment followed. A blood test measured the oxidative stress before and after, so was the antioxidant level from the green tea. The oxidative stress test showed an improvement during the study. The antioxidant level in the blood was higher than before the start of the study. The cognitive function test improved only slightly.

A 2018 study from Singapore looked at the effect of drinking tea (black tea or green tea) regarding symptoms of anxiety or depression. In a group of 614 subjects who were elderly individuals, aged 60 years and above; 59% consumed tea for longer than 15 years. These tea-drinking people were significantly less depressed and significantly less anxious when they underwent psychological tests, compared to non-tea drinkers.

Depression and green tea consumption

There is a 2018 study from South Korea that looked at the link of beverages from 15 studies with depression. 347,691 participants were part  of  these 15 studies, and 20,572 cases of depression developed. Comparing a high consumption of tea or coffee to low consumption, the following statistics were the result: coffee consumption reduced depression by 27%, green tea consumption by 29%.

The Benefits Of Drinking Green Tea

Conclusion

Bioflavonoids are powerful antioxidants. But there are many more substances in green tea and coffee that are all beneficial for our health. One of the studies mentioned identified 15 polyphenols in green tea. But another study said that trying to identify one of the components as more active than the others would be a waste of time. They measured some of the factors by themselves and found that the overall effect was much smaller than green tea as a whole.

Other research has shown that the components of green tea activate several genes. This includes anti-inflammatory effects, prevention of heart attacks and strokes, lowering of blood pressure, anti-cancer effects, improvements of cognitive function, as well as improvement of depression and anxiety. As you can see the effect of green tea is diversified. Don’t hesitate to consume another cup of tea!

Dementia From Excessive Alcohol Abuse

A new study from France documented dementia from excessive alcohol abuse. One million patients who needed admission to hospitals in France for early dementia took part in that study. Dementia is a clinical syndrome, where the cognitive ability deteriorates progressively.

The study from France regarding dementia from excessive alcohol abuse

According to the French National Hospital Discharge database it was especially relevant that alcohol use disorders were present in 16.5% of the men and 4% of the women with dementia. Those who did not have the diagnosis of dementia had only half the amount of alcohol abuse disorders in both sexes.

There are other diseases that can lead to dementia like Parkinson’s disease and Huntington’s disease. These cases were not part of this study.

The association with alcohol abuse was particularly evident in early dementia cases at an age below 65.

Furthermore, alcoholics also have a shorter life expectancy.

Several mechanisms responsible for dementia development

Alcohol can cause dementia in several ways.

  • First of all, alcohol and the metabolic by-product acetaldehyde have toxic effects on the brain. They cause long-term toxic effects and functional brain damage is the result.
  • Furthermore, heavy alcohol abuse leads to liver damage with resulting changes in metabolism. Ammonia production from the cirrhotic liver causes brain damage in a condition called hepatic encephalopathy.
  • In addition, heavy drinking is a strong vascular risk factor. This leads to diabetes, high blood pressure, heart attacks and strokes.
  • Often it is the population group that is uneducated, people who smoke and people with depression who suffer from the effects of alcohol abuse.
  • Finally, heavy drinking is more frequent in men than in women. In men the dementia risk was 4.7-fold, in women 4.3-fold.
  • Obesity, smoking and high blood pressure are also risk factors for dementia. If these cases were not part of the study, heavy alcohol abuse caused an increase in dementia in both sexes by a factor of 3-fold.

Possible biases of the study

Dr. Kostas Lyketsos, a neuropsychiatry professor and director of the John Hopkins Memory and Alzheimer’s Treatment Center did not take part in the study and its investigation. A non- biased observer, Dr. Kostas Lyketsos stated that there is a problem with precision of the data the larger the study population is. In this case there were more than 1 million participants, so a number of biases can influence the outcome of the study. For instance, one problem is that these patients with mild cognitive impairment were inpatients in a hospital. Normally such patients would not be in a hospital. Another fact was that none of the participants had received questionnaires of the amount of alcoholic drinks they consumed, and as a result it is difficult to knows exactly how high the amount of alcohol was that caused the damage to the brain.

Country bias

The large sample size was from only one country, France. This means that we do not know whether there would be ethnic differences between countries. Nevertheless the findings of this study are important. In a 2014 review by the WHO the average person in France consumed 12.2 liters of pure alcohol per year. In contrast the average person in the US consumed only 9.2 liters of pure alcohol in this year. Apart from these concerns it is important to realize that alcohol has toxic effects on the brain. This can also result in dementia.

Other studies regarding alcohol abuse and dementia

The media has praised alcohol for preventing heart attacks. On the other hand, there are other articles in which we hear about alcoholic hepatitis and liver cirrhosis, both of which can be killer diseases. To get some clarification, let us examine the various facts.

Dr. Finnel mentioned that 7.9% of all emergency room visits in the US are due conditions which have an association to alcohol(Ref.1). When the causes of deaths  that are a consequence to alcohol are listed, they are: cancer of the mouth and pharynx, alcohol abuse disorders, coronary heart disease causing heart attacks, cirrhosis of the liver, traffic accidents, poisonings, falls and intentional injuries. You don’t get that from the news. Instead you read about the one glass of red wine per day that is good for women and up to two glasses of red wine that is good for men to prevent heart attacks and strokes.

Bioflavonoids

It is the bioflavonoids and among those in particular resveratrol, that are the active ingredient responsible for heart health.

Resveratrol is a powerful antioxidant that protects against ischemia-reperfusion injuries.  It is responsible for the cardio protective properties of red wine known as the “French paradox” (Ref.2). According to this reference resveratrol contributes to at least 3 processes that stabilize the metabolism.

Toxicity of alcohol

According to the WHO 5.9% of all deaths worldwide is a consequence of alcohol overconsumption.  In 2012 the WHO recorded that 7.6% of deaths in males, but only 4% of female deaths were due to alcohol. Toxicity comes from the breakdown product acetaldehyde, which all cells can convert from alcohol. Liver cells are especially able to do that. According to Ref. 3 alcohol diffuses easily through all of the cell membranes and reaches every organ in the body. The toxicity of acetaldehyde is shutting down the mitochondria, which affects the energy metabolism and causes cell death. The immune system reacts with inflammation, when it attempts to repair the damage.

So, what are the major damages which alcohol can cause? First there is fat accumulation (steatosis), next chronic inflammation followed by necrosis (dying of cells) and finally fibrosis. An example of fibrosis is liver cirrhosis, where non-functioning connective tissue replaces liver cells.

Different tissue sensitivity to alcohol

Certain tissues are more susceptible to alcohol toxicity than others. As the concentration of alcohol is highest in tissues that are in direct contact with alcoholic drinks, cancers related to alcohol consumption develop in the oral cavity, pharynx, larynx, esophagus, and in the colon and rectum. The pancreas is particularly vulnerable to inflammation and fibrotic changes with degeneration into cancer of the pancreas. The heart tissue and the arteries are very sensitive to alcohol.  Hypertension, heart attacks, stroke, cardiomyopathy and myocarditis as well as irregular heart beats (arrhythmias) can develop. The brain is very sensitive to toxic effects of alcohol as well. This causes major depression, personality changes with violent behavior, car accidents and injuries.

Other toxic effects of alcohol on organs

Kidney disease (alcoholic nephropathy) is another illness due to too much alcohol. Five percent  of breast cancers in northern Europe and North America are a direct consequence to the toxic effects of alcohol (Ref.3). Finally, the liver being so active in detoxifying alcohol, will be not functioning and finally develops liver cirrhosis, as described before. This accounts for a lot of premature deaths at a relatively young age (typically in the mid to late 50’s).

Ref. 3 goes on to say that literature exists which claims that 1 to 2 drinks per day would be useful for prevention of heart disease. But the observation of the authors is that people will not discipline themselves to stick to these limits and very quickly enter into the zone of alcohol toxicity. The authors further noted that with regard to causing any kind of cancer there is no safe lower limit; the risk is directly proportional to the amount of alcohol consumed and the risk starts right above the zero point.

The pathologist has the last word

When I studied medicine at the University of Tübingen, Germany I attended lectures in the pathology department where Professor A. Bohle, M.D. demonstrated pathology findings of deceased patients. Dr. Bohle had a special interest in Mallory bodies. These are alcohol inclusion cysts within liver cells that can be stained with a bright red dye.

Histological documentation of toxic effects in livers of corpses

I will never forget when Prof. Bohle pointed out that the livers of this most diverse population, whose bodies we had the privilege as medical students to study, had a rate of 25% positive Mallory bodies. He wanted to impress on us as medical students to watch out for the alcoholics that are usually missed in general practice. Obviously 25% of the pathology population was affected by the consumption of alcohol. It was Prof. Bohle’s hope that we could perhaps interfere on the primary care level before things went out of control. Many of these corpses were the sad results of traffic accidents that could have been prevented. (In 2018 things have changed: seat belts and alcohol limits are standard, in 1968 in Germany they were not).

Alcohol as an aging substance

Consistent use of alcohol on a regular basis will slow down cell metabolism and hormone production significantly. The major effect of alcohol leads to poisoning of the mitochondria in multiple organs, which translates into faster aging and a shortened life expectancy. This in turn results in a change of appearance. An older person who has abused alcohol for a number of years may look 5 to 10 years older than their chronological age.

50% of people above the age of 65 drink daily (Ref.4). Some more statistics: alcohol abuse in elderly men is 4-times higher than in elderly women. 5% to 10% of all dementia cases are related to alcohol abuse. About 15% of older adults are experiencing health risks from abusing alcohol. And about 90% of older adults are using medications. Close to 100% of medications can adversely interact with alcohol (Ref.4).

Social pressure

These are the scientific facts, and then there is social pressure, when you are invited to a party.

When you are young and believe that you are invincible, do you care what the science says? You want to have a “good time” and not worry about consequences. The data about long-term exposure and a slowly increasing cancer risk is there. The wine industry will remind you that 1 drink for women and two drinks for men will protect you from heart attacks. They will withhold the cancer information from you, as they don’t really want to hear about that (yes, it’s bad for their business!).

Resisting social pressure and doing what is good for you

Can you have a good time at a party without drinking alcohol? Yes, you can. You can talk and you can listen; you are probably more with it than those who had too much to drink. I like mineral water and hold on to a glass of that.

I explained in a blog before how I was convinced by three speakers at an A4M conference to join those who abstain from alcohol.

Socializing without alcohol is doable. You may at times miss it, but you can warm up even to a crowd that had a few drinks too much. It is about choice: we can choose what we want out of life.

 

Dementia From Excessive Alcohol Abuse

Dementia From Excessive Alcohol Abuse

Conclusion

Alcohol is a cell and nerve poison. The medical need for “one glass of wine for women and two glasses of wine for men to prevent heart attacks and strokes” has been vastly exaggerated. Fact is that resveratrol and other antioxidants like vitamin C and vitamin E can also prevent cardiovascular disease. They are alcohol-free! The risk of dementia development as a long-term result of alcohol exposure is something that is only now getting attention by the medical profession. We live longer these days, and this makes alcohol exposure over the decades a real threat to our mental wellbeing. Consumption of alcohol needs to be re-evaluated by every one of us. What risks are we willing to take? Is the stress-relieving effect of alcohol worth the risk of losing our mind to Alzheimer’s disease? If we care about our future the answer should be clear!

Dementia And Strokes From Diet Drinks

,You can get dementia and strokes from diet drinks. This is what a recent study published on April 20, 2017 in the American Heart Association Journals has shown. Because of the bad press around sugary drinks more and more people have switched to diet drinks. But the authors of this study have found a correlation of consuming diet soft drinks (with artificial sweeteners), dementia and ischemic strokes.

How was the study done?

The community-based Framingham Heart Study followed patients on diet soft drinks for 10 years. There were two age groups: mean age of 62 and mean age of 69. There were 2888 participants in the younger age group and 1484 participants in the older age group. Researchers observed the younger age group for strokes, the older for dementia. During the observation time there were 97 cases of stroke (82 of them ischemic) and 81 cases of dementia (63 due to Alzheimer’s disease). In comparison to the controls with no consumption of diet drinks, there was an increase of 296% of ischemic stroke and 289% increase of Alzheimer’s disease. This was the data consuming diet soft drinks for 10 years. Another control group had consumed sugar-sweetened beverages. They did not develop strokes or dementia (observation time too short). As can be seen under this link the popular press also reviewed the study.

What do we know about artificial sweeteners?

Here is a brief review of the most common sweeteners.

1. Saccharin

This sweetener’s history goes back to 1879 when the Russian chemist Constantin Fahlberg first noted experimenting with coal tar compounds that one of the end products, benzoic sulfanide, tasted sweet. In fact it was between 200 and 700 times sweeter than granulated sugar! But there were political struggles that accompanied this saccharin throughout the years. There were rumours that in rats saccharin could cause bladder cancer. The health authorities became concerned. This led to Congress passing the Pure Food and Drug Act in June of 1906, to protect the public from “adulterated or misbranded or poisonous or deleterious foods, drugs or medicines.”

The origin of the FDA

This was the precursor of the FDA that would examine all of the medical evidence and consider the pros and cons of sweeteners as well. President Roosevelt took saccharin for weight control to replace sugar. In 1908 Roosevelt felt he had to stop the actions of overzealous Dr. Harvey Wiley, chief of the U.S. Department of Agriculture’s chemical division who was of the opinion that saccharin should disappear from market. Dr. Wiley did not give up his fight and finally the FDA decided to ban saccharin in processed foods, but to continue to allow private sales of saccharin.

2. Cyclamate 

Cyclamate first appeared in 1937. The company marketed the sweetener initially to achieve better control of blood sugars in diabetes. Because of the reduction in sugar consumption it allowed diabetic patients to cut the amount of insulin required to control diabetes. Cyclamate did not have a bitter aftertaste, so in a marketing move the company mixed cyclamate with saccharine. The ratio was 10 parts of cyclamate to 1 part of saccharin , which resulted in the creation of “Sweet ‘N Low. In 1958 the FDA gave cyclamate the GRAS designation: “generally recognized as safe”. The good fortunes of cyclamate did not last long: in 1969 damaging animal experiments showed that cyclamate/saccharin had caused chromosomal breaks in sperm of rats. Another study from 1970 showed bladder tumors in rats. Other studies showed lung, stomach and reproductive tumors in animal experiments with cyclamates/saccharin.

History of Sweet N’ Low sweetener

The FDA wanted to shut down the sale of the Sweet N’ Low sweetener, but public pressure and the food processing industry forced the issue to be brought up in front of Congress. The compromise was to use a warning label: “Use of this product may be hazardous to your health. This product contains saccharin which has been determined to cause cancer in laboratory animals.” In the year 2000 and beyond researchers did several animal experiments. The data from Denmark, Britain, Canada and the United States on humans showed no signs of bladder cancer from exposure to Sweet N’ Low. In 2000 Congress removed the warning labels.

3. Aspartame 

The detection of aspartame occurred in 1965. James M. Schlatter, a chemist, was looking for anti-ulcer drugs, but noticed the intensely sweet flavor when he licked his fingers. This led to the newest sweetener by 1973. We know it by the trade names Equal, NutraSweet or Sugar Twin. As this sweetener consists two amino acids, phenylalanine and aspartic acid. The body metabolizes it except people with phenylketonuria, with certain rare liver disorders or pregnant women. High levels of phenylalanine occur in their blood, because they cannot metabolize aspartame properly. Any food made with aspartame has to carry that restriction on the label, a requirement by the FDA.

Problems with Aspartame

In 1996 W. Olney and his associates presented research that implied that Aspartame would have caused brain tumors in rats. But later these experiments were disproven and studies from children with brain tumors showed “little biological or experimental evidence that aspartame is likely to act as a human brain carcinogen.”

4. Sucralose

The history of sucralose goes back to 1976 when insecticide researchers looked for new types of insecticides. They found that chlorinated sugar worked as an insecticide. One of the researchers tasted sucralose and to his surprise it was very sweet. If you Google “Splenda and insecticide”, you have a hard time finding references regarding the history of sucralose, but 20 years ago I found a detailed description that explained how one of the chemists doing insecticide research accidentally tasted one of the research products, and it was about 600-times sweeter than table sugar.

Sucralose kills ants

Here is one of the few references that explains that sucralose was discovered while looking for new insecticides. I have repeated the insecticide experiment myself in Hawaii where small ants are ubiquitous. Out of curiosity I took a package of Splenda from a coffee shop and sprinkled the contents in the path of ants. In the beginning the ants were reluctant to eat it, but after a short time they came and took it in. They slowed down, and finally they were all dead. A few hours later the only thing visible were dead ants that were only 1/3 of their original size. This was proof enough for me that Splenda, which originates from insecticide research, is not suitable for human consumption.

Side effects of sucralose in humans

In the meantime Dr. Axe in the above references lists the side effects in humans: “Migraines, agitation, numbness, dizziness, diarrhea, swelling, muscle aches, stomach and intestinal cramps and bladder problems.” In the Splenda marketing scheme they decided to first introduce Splenda gradually into diabetic foods as a sweetener, then later sell it to the public at large. Don’t fall for it! It was a side product of insecticide research, and insecticides have the undesirable quality of being xenoestrogens, which block estrogen receptors in women. As a result estrogen can no longer access the body cells, including the heart. The final consequence for a woman is a higher risk for cardiovascular disease. This can cause heart attacks, strokes and cancer. In men estrogen-blocking xenoestrogens can cause breast growth and erectile dysfunction. Taken everything together Splenda seems to be too risky for its sweetness.

5. Other sweeteners

Other sweeteners researchers have not stopped looking for newer, better sweeteners. There is a number of sugar alcohols with less calories than sugar such as erythritol. Another common sugar alcohol is xylitol, used in chewing gum. The advantage is that these are natural sweet alcohols that exist in nature. Xylitol originated from birch wood and the general opinion was that it was useful to fight tooth decay. Manufacturers of chewing gum mixed xylitol into some of their products. Karl Clauss and Harald Jensen in Frankfurt, Germany detected another sweetener, acesulfame potassium, also known by the names acesulfame K, Ace-K, or ACK in 1967 when they experimented with various chemicals. This is known under the brand name “Sweet One”, but is often disguised in processed foods together with other artificial sweeteners to mimic the taste of sugar.

6. Stevia 

Stevia has been used for over 400 years, particularly in South America. It grows like a small bushy herb with leaves that can be taken to sweeten foods.  With modern, reliable extracting procedures (Sephadex column) it is possible to separate the bitter component of stevia and discard it leaving stevia behind without any bitter aftertaste. Stevia occupies 40% of the sweetener market in Japan. In Europe and North America there is a lot of competition with the above-mentioned sweeteners, mainly because of clever marketing techniques. The FDA gave stevia GRAS status in 2008.

What does sugar in soft drinks do?

Sugar is an emotional topic that can get people caught up in heated discussions. The sugar industry and the sugar substitute industry have also powerful lobby groups that provide the Internet and the popular press with conflicting stories to convince you to buy their product. There is good data to show that sugary drinks cause heart attacks, strokes and diabetes. Let’s not forget the metabolism behind the various sugars and starchy foods leading to fat deposits, high triglycerides and high LDL cholesterol.

Cut out sweets, cut out artificial sweeteners, but you can use stevia

Forget the emotions of severing yourself from your favorite fix.  Instead replace the familiar sweet taste you are used to from childhood on with stevia. At least this is what I do. The only alternative would be to take the plunge and cut out any sweet substance altogether, which I am not prepared to do. If you can do it, by all means go ahead. For more details regarding the effects of sugar and starchy foods read the blog under this link.

Dementia And Strokes From Diet Drinks

Dementia And Strokes From Diet Drinks

Conclusion

Diet soft drinks have become very popular. The reason is that studies in the past showed that sugary drinks can cause heart attacks and strokes. Now a new study revealed that diet soft drink consumption is associated with dementia and strokes. These drinks contained saccharin, cyclamate, aspartame or sucralose. They did not contain stevia, a natural sweetener because it is a natural, not a patented sweetener. It seems that companies’ profits are higher with chemical, patented sweeteners.

The problem with manufacturers and the FDA regulatory body

Looking back in time it seems perfectly legal that a company produces a chemical, patents it and sneaks it through the FDA channels for approval. The company then markets diet soft drinks turn out later to produce dementia and ischemic strokes in much larger studies. The FDA originally based their judgement on much smaller experiments for the initial approval. I have noticed that companies are now quietly introducing stevia, a natural sweetener to avoid potential legal problems down the road. Perhaps it is time to follow the Japanese lead where stevia is already occupying 40% of the sweetener market.

Diet And Brain Health

The fact that the topic of diet and brain health keeps popping up in the medical literature, is significant. This year has not been any exception.

The Mediterranean diet in particular has been shown to have very positive effects on postponing Alzheimer’s disease by as much as 5 years.

A clinical study on 674 elderly patients (mean age 80.1 years) without dementia, was published in the journal “Neurology”. It examined the question whether adherence to the Mediterranean diet would affect the degree of brain atrophy. Researchers already knew that Alzheimer’s disease was less common on a Mediterranean diet.

The findings were interesting: a high adherence to the Mediterranean diet led to a higher total brain volume, total grey matter volume and total white matter volume as measured with high-resolution structural MRI scans.

Quality of diet influences cortical thickness of brain

Lower meat intake led to higher brain volume. In addition, more fish intake also caused the mean cortical thickness of the brain to increase. Parts of the brain in Alzheimer’s patients showed atrophy like in the cingulate cortex, parietal lobe, temporal lobe, and hippocampus with good volumes on MRI scans when patients adhered to the Mediterranean diet. These volumes started to shrink when the diet was poor.

Those patients adhering to a Mediterranean diet have brains that on MRI scan look 5 years younger and are much less likely to develop Alzheimer’s disease. Physicians have known for a long time that people, who eat a healthy diet, exercise regularly, don’t smoke and who keep mentally stimulated will generally have healthier brains than people who don’t do these things.

What is the Mediterranean diet?

It involves eating meals derived from plants: vegetables, fruit, cereals, beans and nuts. You can eat fish and poultry twice per week. You cut down the amount of meat and dairy you eat, but you can have a glass of wine per day. Instead of butter olive oil is used instead. Here is more information of what is included in the Mediterranean diet.

Because there is less fat and less high glycemic index carbs in this diet, it is also a diet that lends itself for weight management. You shed a few pounds and reach your ideal body mass index without paying much attention to it.

Apart from the Mediterranean diet the MIND diet has also been shown to prevent brain atrophy. This diet is a combination of the DASH, which physicians developed for controlling high blood pressure, and the Mediterranean diet.

The Mediterranean diet makes you live longer

The Nurses’ Health Study that has been going on since 1976 showed that telomeres, the caps on chromosomes, were getting shorter in nurses who lived on junk foods, but surprisingly nurses on the Mediterranean diet preserved their telomeres. Longer telomeres have an association with slower aging. And people with longer telomeres reach an older age without diseases like heart attacks, liver disease or cancer.

Exercise on top of the Mediterranean diet

In addition to relying on a healthy diet, like the Mediterranean diet, for your health, think about doing regular exercises. These two ingredients together will prevent heart attacks, strokes and other diseases. When you combine exercise with a healthy diet your abdominal girth shrinks as this study showed.

Another study showed that when a Mediterranean type diet is combined with regular exercise, adult onset diabetes occurrence could be reduced by 28-59%.

This is quite a significant effect of two simple interventions: a healthy diet and regular exercise.

Don’t smoke

It does not make sense to go on a healthy diet, exercise and then smoke! Interestingly an Iranian study showed that when people became health conscious, adopted a healthy diet and exercised, they also started to quit smoking. People who did all of this, quit smoking, eating healthy and exercising regularly, were also the happiest and most content.

Exercise your brain

The evidence shows that any stimulation of brain activity, particularly anything that requires active and abstract thinking will protect the brain from developing Alzheimer’s disease.

Another study showed that prevention of Alzheimer’s disease is achieved by quitting smoking, treating high blood pressure, stimulating the brain and treating diabetes.

Diet And Brain Health

Diet And Brain Health

Conclusion

us. This approach will be the most successful way to prevent Alzheimer’s disease. It starts with quitting smoking. It goes on to starting a Mediterranean diet and staying on it. Regular exercise will take care of preventing heart attacks and strokes. But exercise also ensures that all of your brain cells continue to get oxygen and nutrients. This in turn prevents brain shrinkage.

Weight loss included in Mediterranean diet

The Mediterranean diet has a lower calorie content than the Standard American diet, there will be weight loss. The weight loss will continue until you reach your ideal body mass index. You can stimulate your brain by actively doing computer work, doing puzzles, playing a music instrument and phoning friends. In addition you may want to read reading books etc.. All this  will contribute to preventing Alzheimer’s. Watching TV or movies is not an active mental activity. This is passive thinking, which means it is not as valuable as the other activities. Pick a hobby that enhances your life, and your brain will thank you for it too!

Two Is Better Than One: Omega-3 And Krill Oil

Omega-3 fatty acids have gotten a lot of limelight in the press; krill oil was kept more in the background by the media. But both omega-3 and krill oil are important for your health.

What can confuse you is the following paragraph that I picked up from Facebook:

“I cannot believe that in the last 7 days 3 Doctors have asked me what krill omega-3 is. One would think that those who look after our health would realize that the high levels of mercury in the regular omega-3 has reached dangerous levels. Krill oil is harvested from pristine waters of the Antarctic Ocean and tested to be free from harmful levels of mercury. If you have not heard of it, it is for brain, heart, joint and immune health.”

Clarification of what Omega-3 fatty acids are

Depending on where fish is within the ocean’s pecking order of feeding, the levels of mercury of the fish oil that contains omega-3 fatty acids will be higher or lower. Tuna, for instance is one of the predator fish on top of the line. They are large predator fish, and as a result, not a fish you want to eat as it has very high levels of mercury. Salmon on the other hand is lower in the line of predator fish. That’s why it is still recommended to eat salmon two or three times per week. Fish oil is pooled from various fish and then molecularly filtered through a special filter that removes heavy metals like mercury, cadmium and others. Knowing these facts, the Facebook text above may be accurate in stating, “regular omega 3 has reached dangerous levels”, but it is inaccurate for the molecularly filtered omega-3 fish oil, which is the only one I would recommend as a supplement. Having said that there are still significant differences in quality according to a report online that tested 51 common products in the US. The omega-3 fatty acids EPA and DHA are stored in the membranes of platelets and in circulating plasma triglycerides, which is useful for the functioning of the lining of our arteries. This is called endothelium and needs to be healthy to lower blood pressure and prevent hardening of the arteries. Omega-3-fatty acids support the cardiovascular system foremost and the brain secondarily.

Where does Krill oil come from?

Krill oil comes from tiny crustaceans called krill that provides additional benefits that are not found in fish oil alone. Although the initial concentration of raw krill oil has less mercury per milliliter than omega-3 fatty acid fish oil, it still needs to be molecularly filtered to remove heavy metals. Also bear in mind, that the tiny crustaceans live in the same polluted ocean waters as other fish. It is a sad fact that our oceans are no longer pristine! The same is true for the Antarctic Ocean. After the filtering process both krill oil and omega-3 fatty acid fish oil are equal in their quality (free of mercury, other heavy metals, PCB and dioxins).

The omega-3 fatty acids of krill oil have an affinity to bind with phospholipids in red blood cells. This enables krill oil to cross the blood-brain barrier and get into the brain cells providing support for the brain. In this respect krill oil has an edge over omega-3 fatty acids to support the brain. But secondarily it is also good for your heart and the lining of the arteries.

Benefits of marine oils like krill and fish oil

It is best to think about krill oil and omega-3 fatty acids (fish oil) as complementary marine oils that have multiple beneficial effects on the body.

Studies have shown that arthritis and osteoarthritis are helped by krill oil, but also by fish oil. Similarly, heart attacks and strokes are prevented with both krill oil and omega-3 fatty acids. It appears that both oils reduce inflammation in the arteries that are associated with high blood pressure, diabetes, obesity and the metabolic syndrome in obese people. C-reactive protein measuring inflammation was reduced by krill oil up to 30% compared to placebo within 30 days. Patients with arthritis had 20% and more reduction in stiffness and pain.

Krill oil is well absorbed into the brain and can prevent age-related brain shrinkage, preserve cognitive function and memory, prevent dementia and also possibly depression.

Other health conditions improve on both krill oil and omega-3 fatty acids like osteoporosis (in combination with vitamin K2, vitamin D3 and calcium), a weak immune system, diabetes, high triglyceride levels and cholesterol problems. Both marine oils prevent LDL cholesterol from being oxidized, which helps to prevent atheroma formation and hardening of the arteries. This prevents heart attacks and strokes.

Fear mongering Facebook write-ups

In this context let me clarify the fear mongering Facebook write-up cited at the beginning of this blog. It is a misconception to think that krill oil is devoid of mercury. It is only so, if it was molecularly filtered, which removes all of the mercury and more, but it leaves the beneficial DHA and EPA (omega-3 fatty acids) intact. In the same vein omega-3 fatty acids from fish oil are initially more mercury containing, but after molecular filtration are entirely mercury free, the same as krill oil after molecular filtration. But the mix of omega-3 fatty acids is slightly different with krill oil being a bit richer in DHA and attaching to red blood cells easier while fish oil omega-3’s attach to triglycerides in the liquid phase of the blood, called plasma and also to platelet membranes. So neither krill oil or omega-3 fatty acids are better than the other; they are slightly different and that’s why you benefit from a mix of both. It would be a big mistake to follow the Facebook advice above and only take krill oil by blindly trusting the quotation. In my opinion it is simply a marketing plot to get you switched from fish oil to krill oil.

What combination of Krill oil and omega-3 fatty acid should I take?

Most trials with krill oil have been done with 300 mg of krill oil per day.  I take a dosage of one capsule per day of 300 mg. There are several manufacturers that produce similar products. I also take 3 capsules of omega-3 fatty acids twice per day. Each capsule has 647 mg of EPA and 253 mg of DHA, which translates into a daily dose of 3882 mg of EPA and 1518 mg of DHA. Again, there are several products from which you can choose. The reason I take a relatively high dose of fish oil is the fact that I come from a family background with severe arthritis that started in several relatives at an age of 50+. I have no sign of arthritis at age 70. It may be the result of taking these supplements and staying away from sugar and starchy foods. I need my joints to do ballroom and Latin dancing and I also need them to attend the gym regularly. Exercise by itself has been shown to prevent arthritis and prevent heart attacks and strokes. We need the benefit from all these things in combination: good nutrition, supplements and exercise.

Two Is Better Than One: Omega-3 And Krill Oil

Two Is Better Than One: Omega-3 And Krill Oil

Conclusion

Both krill oil and fish oil (omega-3 fatty acids) are needed as supplements to prevent arthritis, strokes, heart attacks, osteoporosis, diabetes, dementia, Alzheimer’s and inflammation. The key to a good krill oil or fish oil supplement is to buy the more expensive products that are molecularly distilled and therefore more concentrated, but also free of heavy metals and other contaminants. These supplements are only a small part of your overall anti-aging program that needs to include good nutrition (organic food), exercise, other supplements and if necessary bioidentical hormone replacement.

Be Creative, Prevent Dementia

Here is a recent research finding from the Mayo Clinic that caught the media’s attention: be creative, prevent dementia. The study found that when people engage in creative things they could delay the onset of Alzheimer’s and dementia. There are a number of various causes of dementia. But the end result is that there is an inflammatory condition within the brain that leads to a loss of nerve cells and nerve cell connections. When brain cells and nerve cell connections are lost, memory fades, particularly in the frontal brain and in the hippocampus area.

The study

In an April 8, 2015 publication from the Mayo Clinic in Rochester, MN and Scottsdale , AZ 256 participants aged 85 years and older (median age 87.3 years, 62% women and 38% men) were followed for 4.1 years. The researchers measured mild cognitive impairment (MCI) with psychological tests. At the time of recruitment into the study all of the tests for MCI were normal. As the study progressed it became apparent that there were various risk factors that caused the onset of MCI, which is the immediate precursor of dementia/Alzheimer’s disease. There was an association with the genetic marker APOE ε4 allele and a risk of 1.89-fold to develop MCI. Subsequently these patients developed Alzheimer’s disease.

Factors that can cause mild cognitive impairment

If there were currently symptoms of depression present at the time of being enrolment into the study, the risk of MCI development was 1.78-fold. Midlife onset of high blood pressure led to a 2.43-fold increase of MCI development. A history of vascular diseases had an association of 1.13-fold higher MCI development. The good news was that four activities had an association of a lower risk to develop MCI with aging. When the person participated in artistic activities in midlife or later in life the risk for MCI development was reduced by 73%. Involvement in crafts reduced the risk for MCI by 45%. Engagement in social activities reduced the risk of for MCI by 55%. In a surprise finding the use of a computer late in life had an association with a 53% reduction in MCI development. These are very significant observations.

What we can learn from the study

When you get older it is important that you prepare yourself for an active retirement. You may want to enrol in dance classes, as this combines physical activity with brain activity. Here you have to remember learnt responses (from old moves you know). You also learn new dance moves (therefore creating new nerve cell connections). You could start a hobby where you create something (arts and crafts, painting etc.). Grandma Moses did this, and she not only became famous with her artwork, but she aged gracefully; she turned 101 years old).

Treat your brain with respect

We have to treat our brain with respect. We need to give it proper nutrition and avoid cardiovascular disease as it is known that whatever is good for the heart is good for the brain.

Eat a Mediterranean diet and avoid junk foods including processed foods. If at all possible eat organic foods. Take your fish oil supplements (omega-3 and DHA), as the DHA will provide the material necessary to build up new brain cells. The omega-3 fatty acids are necessary for a healthy heart and healthy blood vessels.

Exercise regularly, cut out sugar from your diet, seek mental stimulation

Regular exercise will improve your brain circulation. If you take the steps mentioned you will prevent arthritis. And by cutting out sugar and starchy foods your brain will stay sharper for longer. Nurses in care homes for Alzheimer’s patients have known for a long time that Alzheimer’s patients crave sugar and sweets. This leads to hyperinsulinism and Alzheimer’s disease. So, let’s take the consequences and cut out sugar and sweets to prevent Alzheimer’s.

Various publications described the benefit of physical exercise. But now an additional tool is to have the aging persons enrol in crafts courses, journal clubs, discussion groups, walking groups, bridge groups or religious gatherings. That will stimulate the brain to form new circuits and buildup new memories. Artistic activities and learning the use of the computer are additional things that will reduce the risk of developing MCI and later dementia or Alzheimer’s disease.

Be Creative, Prevent Dementia

Be Creative, Prevent Dementia

Conclusion

As the baby boomers age and enter into the old age category these observations are very important. We should think about doing some of these things now, so we do not have to overcome inertness later. The worst you can do is to become a couch potato and watch TV all of the time. Watching other people doing sports activities does nothing for you unless you walk on a treadmill while you watch TV. I do not intend to be hard on you; I am just passing on these new research findings and practicing them myself. The final choice is up to you.

Preserve Your Memory

At the 22nd Annual A4M Las Vegas Conference in mid December 2014 Pamela Smith gave a presentation entitled ”How To Preserve Your Memory At Any Age”. She gave a comprehensive overview of what you can do to prevent Alzheimer’s disease. The better we understand the causes of Alzheimer’s the more we can interfere with the biochemical processes that lead to Alzheimer’s or dementia. Various parts of the brain have different functions like pattern recognition, interpreting auditory and visual stimuli and so on. In the past researchers thought that after the brain development it would be stationary until we die. But they have now shown that instead the brain continues to develop even after the teenage years. New brain cells can develop as long as we live and new synapses, the connections between brain cells can form all the time.

A lack of sleep causes insulin levels to rise, which causes a lack of memory. Alzheimer’s disease has been termed diabetes type 3 because of this close connection of memory loss and uncontrolled blood sugar levels. In fact diabetics are three times more likely to develop Alzheimer’s disease.

Subunits of the brain and neurotransmitters

There are several subunits of the brain like the hypothalamus, thalamus, hippocampus and the amygdalae, which are important for normal brain function and memory. The hippocampus in particular is a major memory-processing unit, which indexes, constructs and rearranges memories.

Apart from the anatomy of the brain, neurotransmitters are important for the proper functioning of the various parts. Although there are more than 100 of them the most important neurotransmitters are acetylcholine, GABA, glutamate, dopamine and serotonin. Each of these neurotransmitters binds to only one specific receptor before a neuron sends a signal to the next. There is a decline in the speed of neurotransmission with age and also a memory decline. Compared to the memory in a young person a person at the age of 75 has a decline in memory function of about 40%.

Why do people experience memory decline?

Apart from genetic predisposition the majority of people who come down with Alzheimer’s disease do so because of neglecting the body and their brain. Neglecting elevated blood pressure by not treating it properly with medication will lead to vascular dementia. As already mentioned earlier hyperinsulinemia (too much insulin in the blood) from obesity, untreated type 2 diabetes and metabolic syndrome is another mechanism.

There is an association of lack of exercise with a higher risk of developing Alzheimer’s, so is insomnia and a lack of sleep (less than 7 hours per night). With aging there is often poor nutrition, lack of absorption of nutrients, inflammatory bowel conditions with poor absorption of nutrients and body inflammation. A significant portion of the population is deficient for various enzymes in the methylation pathway, which can lead to high homocysteine levels and the danger of premature heart attacks and vascular dementia. Psychological health also affects memory loss, as do depression and anxiety. Toxins like heavy metals, fuels, pesticides, solvents and fluoride can over time lead to memory loss and Alzheimer’s as well.

Lifestyle habits and Alzheimer’s

There are many lifestyles that cause memory loss: too much stress (from high cortisol levels that damage the hippocampus); smoking that damages acetylcholine receptors; chronic alcohol abuse leads to memory problems from the toxic effect of alcohol on brain cells, which in turn causes a disbalance of serotonin, endorphins and acetylcholine in the hippocampus.

Lack of exercise is an independent risk factor for the development of Alzheimer’s disease. Exercise increases the blood supply of the brain, strengthens neural connections and leads to growth of neurons, the basic building blocks of the brain. Mood-regulating neurotransmitters are increased (serotonin, endorphins).

Sleep deprivation leads to memory loss, but so does the use of aspartame, the artificial sweetener of diet sodas.

Sugar consumption and too much pasta (which gets metabolized within 30 minutes into sugar) causes oxidization of LDL cholesterol and plaque formation of all the blood vessels including the ones going to the brain. On the long-term this causes memory loss due to a lack of nutrients and oxygen flowing into the brain.

Hormone changes

A lack of testosterone in men and estrogen in women interferes with cognition and memory. For this reason it is important after menopause and andropause (=the male menopause) to replace what is missing with the help of a knowledgeable health professional.

Too much DHEA from stress can decrease memory, but too little DHEA from aging can also do this. Alzheimer’s patients have DHEA levels that are 48% lower than men and women of the same age who have normal memories. Pregnenolone is a precursor of DHEA, estrogen, progesterone and testosterone. Dr. Smith called pregnenolone the “hormone of memory in the body”. At an age of 75 most people have a 65% lower level of pregnenolone than a persons in the mid 30’s. Pregnenolone keeps your brain balanced between excitation and inhibition, helps you to cope with stress and gives you energy.

Ask for input by hormone specialist

But before you consider supplementing with a pregnenolone hormone level, this should be ordered by a knowledgeable health professional. Dosing can be tricky as too much pregnenolone can result in too much DHEA, estrogen, progesterone or testosterone.

Progesterone is manufactured inside the brain, spinal cord and nerves from its precursor, pregnenolone, but in women it also comes from the ovaries until the point of menopause. Progesterone is needed in the production of the myelin sheaths of nerves and it has a neuroprotective function. In menopausal women bioidentical progesterone is a part of Alzheimer’s prevention.

Melatonin is a hormone, a powerful antioxidant and a neurotransmitter at the same time. It helps in the initiation of sleep, stimulates the immune system and protects from the toxic effects of cobalt, which has been found to be high in Alzheimer’s patients.

Other factors contributing to Alzheimer’s

Any inflammatory condition can trigger destruction of neurons, so do the beta-amyloid proteins associated with Alzheimer’s. Contributory factors can be food allergies, disbalance of gut bacteria, recreational drugs (particularly ecstasy) and certain medications. Dr. Smith stated that the most common foods causing allergies that affect the brain are: sugar, wheat, dairy, eggs, shellfish, potatoes, beef, tomatoes, corn, coffee, peanuts, roasted soy beans and yeast.

Dr. Smith mentioned that these medications can affect memory: statins, sedatives, steroids, levodopa, muscle relaxants; antihypertensive drugs, antidepressants, antibiotics, anticonvulsants, anti-arrhythmic drugs, pain relieving drugs (analgesics) and antihistamines. If you are on any of these, you may want to discuss alternatives with your doctor. Dr. Perlmutter mentioned in Ref. 1 that statins interfere with brain function and can lead to Alzheimer’s.

Promoting brain health

Medication helps only to stall further memory loss for up to 6 months, so Dr. Smith said about medications only: “much research is still needed in this area”.

On the other hand she stated that many foods, vitamins and supplements in combination could improve memory and prevent the development of Alzheimer’s disease. She spent considerable time in the remainder of her talk on details regarding foods, vitamins and supplements.

Dr. Smith said that we need to eat foods that are rich in antioxidants like blueberries, apples, raspberries, blackberries and strawberries; cherries, cranberries, cooked kale, garlic, grapes, prunes, raisins and raw spinach. But at the same time she stressed that we cannot trust the food industry anymore, and we need to buy organic foods. She gave an example of the “dirty dozen” as defined by the environmental working group (contaminated fruits and vegetables).

Food intake also applies to portions:eat 5 to 6 smaller meals per day. Consume red meat only three times per week.

The brain needs fats like nuts and seeds: walnuts, almonds, pine nuts etc.

Fish also contains healthy omega-3 fatty acids and DHA. The problem with predator fish like tuna or swordfish is that they are contaminated with mercury. But wild salmon and mackerel are still OK. A good alternative is to supplement with pharmaceutical grade EPA/DHA omega-3 capsules. They are molecularly distilled, which means they are not contaminated with mercury or PBC’s and they are more concentrated; they typically contain 1000 to 1400 mg of EPA/DHA per capsule. One to two capsules twice per day (a total of 2 to 4 per day) would be a good anti-inflammatory dose.

Specific food recommendations

Use olive oil and coconut oil for cooking; avoid the omega-6 oils (safflower oil, grape seed oil, sunflower oil, corn oil to just mention a few). These latter oils, which are heavily advertised by the food industry, create too much arachidonic acid leading to body inflammation. Your brain is very sensitive to inflammation, which causes Alzheimer’s. For the same reason avoid deep fried foods and processed foods.

There is more you need to watch for: no food additives, no artificial food colorings, no preservatives, flavors and MSG. Be alert about the food industry’s alternative “language” or terminology for MSG: “natural flavor”, “yeast extract” etc.

Preserve Your Memory

Preserve Your Memory

Brain nutrients

Dr. Smith reviewed a long list of brain nutrients that support the brain in its metabolism and prevent the development of dementia and Alzheimer’s disease.

I will only highlight the most effective and established nutrients here.

DHA: It has been known since 1999 that Alzheimer’s patients are missing DHA in their system. Molecularly distilled fish oil with high omega-3 fatty acids (both EPA and DHA) is one of the mainstays of prevention of inflammation in the body and the brain. 2 capsules twice per day of the concentrated 1000mg to 1400 mg capsules is desirable to prevent Alzheimer’s disease.

Phosphatylserine (PS): This phospholipid is part of the membrane of brain cells and controls what nutrients enter into them. It also increases the neurotransmitters acetylcholine, serotonin, norepinephrine, epinephrine and dopamine. Dr. Smith mentioned that PS is naturally present in foods like brown rice, fish, soy and green vegetables (particularly the leafy ones). The daily dosage recommended by Dr. Smith is 300 mg (note: some people develop a bothersome, but harmless bitter taste in the mouth at this dose; in this case take a lower dose like 100 or 200 mg per day).

Other supplements like Ginkgo biloba, alpha lipoic acid and others

Ginkgo Biloba: It improves blood flow to the brain and counteracts shrinkage of the hippocampus with age. Dr. Smith recommends 60 mg to 240 mg daily.

Alpha Lipoic Acid: Alpha lipoic acid is an antioxidant, helps stimulating the sprouting of new nerve cells and nerve fibers. Take 100 mg of alpha lipoic acid daily for memory.

Dr. Smith recommended many other supplements, which I will not explain in detail here: B vitamins, vitamin E and C, carnosine, acetyl-L-carnitine, boron, ginger, coenzyme Q-10 (or CoQ-10), curcumin, vinpocetine, zinc, grape seed extract, blueberry extract, Ashwaganda, glyceryl-phosphoryl-choline, SAMe, huperzine A and DMAE.

Dr. Smith discussed the benefits of CoQ-10 supplementation and reminded the audience that “whatever is good for the heart, is good for the brain”. She recommended to read Dr. Perlmutter’s book from which this phrase was borrowed (Ref. 1).

Genetic factors

Dr. Smith pointed out that there are about 5 genes that have been detected that are associated with Alzheimer’s disease and in addition the apolipoprotein E4 (APOE4). About 30% of people carry this gene, yet only about 10% get Alzheimer’s disease. This shows you how important lifestyle factors are. Physicians call this epigenetic factors. The can suppress the effect of the APOE4 gene. She also stated that our genes contribute only about 20% to the overall risk of developing Alzheimer’s disease. This leaves us with 80% of Alzheimer’s cases where we can use the brain nutrients discussed above and exercise to improve brain function.

Conclusion

Don’t wait for Big Pharma to develop a magic pill. Follow the simple steps in combination that Dr. Pamela Smith talked about in her presentation: Exercise, have organic food to keep toxins out of your body and brain, replace missing hormones with bioidentical ones and take supplements that are known to be effective (link for male menopause). In other words provide the right environment for your genes to work properly without getting Alzheimer’s disease.

Older Grumpy People Have Higher Risk Of Dementia

Although in this recent study from Finland researchers found that grumpiness in older age seems to lead to dementia at a faster rate, I like to emphasize here that there may be an under lying problem of hormone deficiency.

Other studies have shown that in males low testosterone levels are associated with grumpiness and dementia is setting in sooner in those males who are deficient for testosterone. For older grumpy females it is the lack of progesterone that has been found to be deficient and when you replace it, memory comes back, symptoms of menopause reverse themselves and the grumpiness is gone. Testosterone replacement may be required by as many as 1 in 4 men in the their 40’s as is summarized in the article from Great Britain.

How can we tell whether there is a change in an older man? There are quite a few symptoms that can be seen by loved ones around this man: an increase in abdominal girth, shrinking muscles, lack of energy, irritability. The key is to get him to the doctor and ask the doctor to order a bioavailable testosterone blood test.

According to medical research 84% of men and 62% of women in the age group of 57 to 64 have been sexually active in the previous 12 months. Take an older age group of 65 to 74 and still 67% of men and 40% of women are sexually active. Fast-forward to age 75 to 85 and the rate has dropped to 39% of men and 17% of women (Ref.1). A person’s sexual activity is a barometer how well the hormones are balanced. These figures show that bioidentical hormone replacement has not been well accepted. Women have a reason as they were misled by Big Pharma as was shown in the

Older Grumpy People Have Higher Risk Of Dementia

Older Grumpy People Have Higher Risk Of Dementia

Women’s Health Initiative:

The National Institutes of Health had funded a large study (the Women’s Health Initiative) to clarify what was going on with regard to side effects and effects of HRT.

Unfortunately, synthetic non-bioidentical hormone products were used in these studies (Premarin and Provera) instead of bioidentical estrogen and progesterone. The results of the Women’s Health Initiative were devastating. In 2002 doctors were warned that Premarin and Provera used as HRT would cause increased heart attack rates and breasts cancer, which led to premature death. Overall the placebo group did better than the experimental group and this is why the trial was prematurely stopped.  As a result of the wide publicity regarding the negative results of the Women’s Health Initiative postmenopausal women either do not see their physician for hormone replacement or are advised by conventional doctors that only small amounts of Premarin could be used for not more than 5 years for fear of causing breast cancer. Medico-legal considerations are at play and the whole issue of HRT after menopause has been politicized.

Problems now for HRT:

It is like a negative shadow has been cast forward with regard to hormone replacement because of the Women’s Health Initiative. People are still confused and don’t understand that the synthetic hormone-like drugs from Big Pharma are like an ill-fitting key for the hormone receptors in the body whereas bioidentical hormones are the perfect fit.

Otherwise there would not be a 45% drop-off (from 62% to 17%) in sexual activities in women from age 60 to 80. Men have it somewhat easier: their drop rate between age 60 an 80 is also 45% (from 84% to 39%), but as they entered into male menopause 10 to 15 years later than women did with menopause, their sexual activity is still double that of women at the age of 80.

However, if people could overcome their unrealistic fear of bioidentical hormones, hormones that fit the body’s hormone receptors a lot more people would be encouraged to use bioidentical hormone replacements.

What, if the grumpy, old man is willing to see his doctor?

The doctor should look at all of the hormones including a fasting insulin level as hyperinsulinism often complicates hormone replacement. Thyroid, which often is also lowered at an older age should be also tested (T3, T4 and TSH). A saliva hormone test can show a panel of 5 hormones: cortisol, DHEAS, testosterone, progesterone and estradiol. As hormones are in a balance with each other this allows to compute the testosterone to estrogen ratio, which ought to be 20 or higher. But hormones alone are not the answer. There needs to be a combination of proper nutrition (cut out sugar, starchy foods, preferably switch to organic foods to escape the xenoestrogens that foul up your hormone balance), also exercise and use vitamins and supplements. I have summarized all of this in my recent book “A survivor’s Guide to Successful Aging” (Ref.2).

When the hormone tests come back the doctor will likely order the missing hormones (hopefully as bioidentical hormones).

It can take 2 to 3 months before the full effect of bioidentical hormone replacement is seen. But most men will be astounded how well they can feel. He will notice that he does not tire with exercising. His muscle mass builds up; his posture improves. His stamina comes back. He will find that the previously foggy thinking is gone and his thought processes have become clear again. And yes, his sex live comes back. So now he has to talk to his sex partner about her bioidentical hormone replacement so they both can enjoy the benefits!

Hidden benefits of bioidentical hormone replacement:

The bones become stronger, the heart beats harder and better, the brain thinks clearer, because the key organs like the brain, the heart and the bones have the appropriate hormone receptors (in both sexes).  No, this is no exaggeration. This can be measured by an exercise tolerance test (for the heart). Bone density can be measured and has been done (2% to 4% increase per year). Brain function is indirectly visible to the people around the person: apart from new vitality, improvements in mood and more energy, the grumpiness is gone and the person is perceived as a pleasant person once again.

Conclusion:

The observation of an “old, grumpy man” when he entered the male menopause is accurate, but should not distract from the fact that he has a responsibility to look after himself. It is important to recognize that it is not only women who enter the menopause, but that men 10 to 15 years later will do the same. Both sexes enter a state of hormone disbalance that is treatable. The answer is to replace the hormone deficiency with the missing bioidentical hormones.

Early Alcohol Use Will Result In Memory Loss Later In Life

Researchers found that heavy alcohol use in males during midlife paves the way to memory loss from dementia later in life.

I thought that this would be a good topic to review the effect of alcohol in general. Alcohol is a known cell poison, yet cardiologists keep on referring to the beneficial effects of that 1 glass of wine per day that will prolong your life. I will attempt to explain these diverse effects, where small amounts are supposed to be good for you while high amounts can be very damaging.

Review of the effects of alcohol

50% of the world population drinks alcohol, 10% to 20% have chronic alcoholism (Ref.1).  Just recently a Guardian news study was released showing that an astounding 25% of Russian men die before reaching the age of 55, compared to only 7% of men in the United kingdom and less than 1% of men in the US. The study looked at the effects of consuming large amounts of vodka.  There are about 10 million chronic alcoholics in the US. Chronic alcohol consumption leads to 100,000 deaths every year in the US. More than 50% of these deaths are from traffic accidents, the rest from medical problems caused by alcohol (Ref.1). Most of the alcohol gets detoxified through the liver cells and is metabolized into acetaldehyde. This involves the cytochrome P-450 system. That means that when a person also takes narcotics, sedatives or psychoactive drugs that are also metabolized through this liver enzyme system drugs and alcohol are taking much longer to be metabolized. This can lead to lethal overdoses that we hear about on TV all the time, hence the warning that you must not mix alcohol with drugs.

Early Alcohol Use Will Result In Memory Loss Later In Life

Alcohol is a cell and nerve poison. The most vulnerable organs in the body are the liver, brain, heart, pancreas, bone marrow and stomach. So, here are a number of conditions caused by drinking alcohol:

a)    Anemia: When a person drinks heavily and regularly anemia shows up in a blood test. Alcohol has a toxic effect on the bone marrow, which interferes with the production of red blood cells. But certain vitamins required by the bone marrow to manufacture red blood cells are often also missing in the diet of an alcoholic, which contributes to anemia as well.

b)    Cirrhosis of the liver develops in 10% to 20% of heavy drinkers. With cirrhosis part of the liver cells get replaced by fibrotic tissue and in advanced cases this can lead to a hepatic coma and death. Others are developing alcoholic hepatitis. This is an inflammation of the liver with fever and jaundice where the skin and eyeballs turn yellow. It is associated with severe abdominal pain.

c)    Gastritis: Alcoholic gastritis is common, but often undetected. The affected individual may just have stomach pains for a few days, or vomit food and/or blood in addition. With continued use of alcohol it may turn chronic. Alcoholic gastritis can turn into gastric ulcers with massive bleeding that often lead to death.

d)    Pancreatitis: The pancreas is a particularly vulnerable glandular tissue, which gets damaged by regular alcohol intake and with chronic alcohol intake gets partially replaced by fibrotic tissue causing the feared and painful chronic pancreatitis. This is a condition with vomiting and severe abdominal pains that can be unrelenting.

e)    High blood pressure, seizures, dementia, depression, heart irregularities and nerve damage:

You may ask yourself how all of these conditions would be reasonably under one heading. The heading for this is “nerve damage”. Let me explain: The sympathetic nerve is very sensitive to alcohol toxicity and when the sympathetic nerve fibers are damaged, you will develop high blood pressure. You see your physician, get blood pressure medication, but the pressure is difficult to control, if you continue to drink alcoholic beverages. It does not make sense to just add blood pressure pills and hope that this will cure your problem. Seizures are due to direct nerve damage in the more sensitive parts of the brain, which will cause these areas to produce extra electrical activities, which we call seizures. Again, just treating with anti-seizure medications is not the solution. Avoidance of alcohol is the other part of the treatment schedule. Dementia from heavy alcohol use is due to direct nerve atrophy in the brain. Our brain shrinks normally 1.9% to 2.8% per decade, depending on which research papers you read. But in the presence of heavy drinking the frontal lobe of the brain is particularly vulnerable to brain shrinkage.

As this publication shows, mild and moderate drinkers did not suffer more frontal lobe shrinkage than abstainers, but heavy drinkers had a 1.8-fold higher risk of frontal lobe shrinkage on average when compared to abstainers. It was calculated that alcohol had contributed 11.3% to that frontal lobe shrinkage.

The rest of the toxic effect on the nerve tissue explains why depression would develop. The frontal brain contains most of the serotonin producing nerve cells. When serotonin-producing nerve fibers get damaged, the body does not produce enough serotonin to prevent depression from setting in; GABA producing cells often also get damaged, which causes anxiety. It’s not good enough to just prescribe anxiolytic drugs to which the patient will get addicted. The whole person needs to be treated, and abstinence from alcohol has to be part of the program.

Heart irregularities (atrial fibrillation, ventricular fibrillation) can be life-threatening complications due to the toxic effect of alcohol on the nerve fibers within the heart muscle. Emergency physicians are aware of the connection of these conditions to alcohol consumption. Some people’s hearts are more sensitive to the effects of alcohol than others. The most common cause of temporary atrial fibrillation is excessive alcohol intake (holiday heart) according to Ref. 2.

Finally there is the effect of alcohol on nerves in the body. This explains that heavy alcohol consumers can come down with painful pins-and-needles sensations in their hands and feet or with numbness or loss of muscle strength. When the parasympathetic nervous system is affected embarrassing incontinence or constipation can result. Erectile dysfunction in men is also very common. Viagra and continuing to drink is not the solution.

f)      Gout: This painful formation of uric acid crystals in joints can be precipitated in sensitive individuals by consuming alcohol in combination with eating large helpings of beef. There may be a history of gout in the family. Treatment for this is to refrain from alcohol and avoid foods that are leading to uric acid production when ingested.

g)    Cancer: When the body detoxifies alcohol in the liver, the breakdown product is acetaldehyde, which is a known cancer producing substance. A whole array of cancers are known, which come from heavy, chronic alcohol consumption: cancers in the mouth, larynx, esophagus, stomach, pancreas, liver and colorectal cancer have all been linked to excessive alcohol intake.

h)    Cardiovascular disease: heart attacks and strokes can be caused particularly by binging; it is thought that binging makes platelets from the blood more sticky so they clump together and cause blood clots, which in turn leads to heart attacks and strokes.

i)      Infections: Alcohol weakens the immune system, which is another effect on the bone marrow similar to causing anemia, except that this is the toxic effect on the white blood cells and lymphocytes. Heavy alcohol consumers are more prone to pneumonia, to HIV, sexually transmitted diseases, and tuberculosis.

Cardiology view of preventative alcohol

Despite all of these hair raising toxic effects cardiologists have painted the rosy picture that 1 glass of wine for women and 2 glasses of wine for men per day will prevent heart disease. What is the true story here?

Ref.2 points out that there are about 100 prospective studies that confirm that there is an inverse relationship between mild to moderate alcohol consumption and “heart attack, ischemic stroke, peripheral vascular disease, sudden cardiac death, and death from all cardiovascular causes”. It describes further that the reduction of risk in these various studies was persistent and consisted of a 20% to 45% risk reduction. Using blood tests investigators have found that this is because of an increase of HDL cholesterol, reducing blood clotting, making platelets less sticky and reducing inflammation as evidenced by a reduction of the C-reactive protein. Further research has pinpointed that it is the phenols and resveratrol that are contained in alcoholic beverages that are responsible for the beneficial effects. The bad news is that three glasses of wine or more do the opposite, so does binge drinking. Unless you are extremely disciplined and never increase your allowed limit (1 drink for women, 2 drinks for men) you will CAUSE heart disease rather than PREVENT it (Ref.2). Some people have a family history of breast cancer or colon cancer and they should avoid alcohol altogether; also people coming from alcoholic families should avoid alcohol.

Conclusion

Where does this leave us with regard to prevention of heart attacks, strokes and hardening of the arteries in the legs (peripheral vascular disease)? If you are disciplined and stick to the limits, you could prevent 20% to 45% of cardiovascular risk. The brain study mentioned in the beginning of the blog would also confirm that there was no difference between dementia or brain shrinkage when mild to moderate drinkers were compared to abstainers over 10 years. What is not told by the wine industry is that the same effects that prevent cardiovascular disease in mild to moderate drinkers can also be achieved by natural means: exercising regularly will raise your protective HDL cholesterol; taking ginkgo biloba, flax seed and omega-3 fatty acids thins your blood and the platelets are getting less sticky; omega-3 reduces inflammation and resveratrol elongates telomeres making you live longer. At the A4M conference in Las Vegas in December 2011 there were three speakers who pointed out that even small amounts of alcohol will poison mitochondria of your cells and interfere with normal hormone action. This was enough to make me join those who abstain alcohol completely. One thing has not yet been investigated in long-term studies, namely how small effects of alcohol may affect the body over several decades and over an entire lifetime. Despite all the promises of interest groups that red wine is a trendy drink for those interested in heart health, the fundamental long-term studies are missing. What does a guy do with a healthy heart and a brain that is not functioning too well? I just do not want to be the guinea pig in that worldwide study.
