Poor Diet Habits Can Cause Alzheimer’s

By | Alzheimer’s disease, Dementia, diet, exercise, food, Heart Disease, High Blood Pressure, Inflammation, Nutrition, Obesity, Smoking

A new study from the Brock University in St. Catharine’s, Ont. showed that poor diet habits can cause Alzheimer’s. Specifically the risk for Alzheimer’s was a combination of high saturated fats in the diet in combination with too much sugar.

The third triggering factor was the normal aging process that also contributed to the development of Alzheimer’s.

The study showing that poor diet habits can cause Alzheimer’s

Master student Bradley Baranowski and PhD student Kirsten Bott conducted the experiments under the supervision of Assistant Professor of Health Sciences Rebecca MacPherson. The experimental group consisted of middle-aged mice that were observed for 13 weeks. They received a high-fat/high-sugar diet. The control group received a normal diet.

The experimental group with the high fat/high sugar diet was aging prematurely. They also showed elevated inflammatory markers, elevated insulin levels and cellular stress. Dr.MacPherson mentioned that the middle-aged mice would be comparable to humans aged 40 to 60. “[We’re] trying to see what the initiating signals are that can lead to progression of Alzheimer’s disease,” MacPherson said.

Lifestyle choices matter

“People often view Alzheimer’s disease as a genetic disease when in fact, genetic mutations leading to Alzheimer’s accounts for less than five per cent of cases,” Baranowski said in the press release. “This study highlights that our lifestyle choices matter and can potentially put us at risk of developing or progressing neurodegenerative diseases such as Alzheimer’s.”

Other studies that support the concept that lifestyles matter

Over the years many other researchers have analyzed what factors contribute to getting Alzheimer’s. It probably is a combination of several factors.

Age

Age is one of the major risk factors. Most Alzheimer’s patients are above the age of 65. Above 65 the risk doubles every 5 years. By the time we are 85 our risk is 1/3 to get it.

Family history

If you have a parent, brother or sister who came down with Alzheimer’s, you have a higher risk of getting it.

Environmental factors

Often environmental factors like eating too much sugar or too much saturated fat are confused with family history factors. Nutritional habits in a family can be like a tradition. It may appear as if this is a family history of Alzheimer’s when in reality poor eating habits were passed on from generation to generation. A lot more research is necessary in this area.

History of Head injury

A history of a closed head injury carries with it a higher risk of Alzheimer’s later in life. We need to use seat belts in cars and helmets when bicycling. Avoid risky sports activities where you would sustain a traumatic brain injury.

Heart disease

There is a link between heart disease, diabetes, stroke, high blood pressure, high cholesterol and Alzheimer’s. When brain arteries get clogged, the brain deposits more beta-amyloid protein as plaques. This is a sign of early Alzheimer’s disease.

Older Latinos and older African Americans

Older Latinos have a 1 ½-times higher risk than older whites to get Alzheimer’s and dementia. On the other hand older African-Americans are 2-times more likely than older whites to come down with Alzheimer’s. The reason for this is not entirely clear. But a big factor likely is the cardiovascular risk that is higher in Latinos and African Americans. This translates into a higher risk for Alzheimer’s.

Prevention of Alzheimer’s disease

There are more publications that point out that Alzheimer’s disease is largely preventable by cutting out those factors that contribute to its development.

Here is a list of steps to follow in order to prevent Alzheimer’s disease.

  1. First of all treat diabetes, high blood pressure and obesity aggressively. This eliminates cardiovascular risk factors, which keeps the brain vessels open.
  2. Furthermore quit smoking. By preserving the cardiovascular system the brain stabilizes.
  3. Another important factor is physical activity: exercise daily! This maintains cardiopulmonary fitness. It also keeps your brain vessels open.
  4. Also, take care of your diet: eat balanced meals and avoid junk food. A Mediterranean diet or the MIND diet are examples of diets that help prevent Alzheimer’s. Note that these are low sugar and low saturated fat diets. This fits the initial observation that you read in the beginning of this blog. Mice on a high fat/high sugar diet showed premature aging and developed Alzheimer’s. Knowing this, it is good to do the opposite: cut out excessive saturated fats and sugar. Sugar increase LDL cholesterol and triglycerides, which leads to hardening of arteries.
  5. Mental stimulation is another important factor for preventing Alzheimer’s. With lifelong bilingualism there was a delay of about 4.5 years in onset of dementia. The ACTIVE study is in the link above. It showed that mental stimulation could indeed delay the onset of Alzheimer’s over a 10-year period. 
Poor Diet Habits Can Cause Alzheimer’s

Poor Diet Habits Can Cause Alzheimer’s

Conclusion

Above all, I cannot emphasize enough how important a healthy diet is for a healthy mind. The combination of an overabundance of saturated fats and refined sugar was found to be the cause of premature aging in mice. But likewise, we know from human trials that this also causes premature aging in humans and higher incidence of Alzheimer’s. As a result, it is logical to recommend a lower intake of saturated fat and to reduce sugar intake. It will prevent hardening of the arteries and slow down the development of Alzheimer’s.

But there are many other recommendations to avoid getting Alzheimer’s: quit smoking. Stay physically active by exercising daily. Use a Mediterranean diet or the MIND diet to prevent Alzheimer’s. Clinical trials with these diets have shown them to be effective. Treat diabetes, high blood pressure and obesity aggressively as this will stabilize your metabolism. As a result it also prevents Alzheimer’s. Finally, stimulate your brain every day by doing various activities. This forms new synaptic connections inside your brain and postpones Alzheimer’s from setting in as you age.

What Makes Chips Addictive?

By | addiction, alcohol, diet, Drugs, food, Nutrition, Obesity, sugar

When you emptied an entire bag of potato chips, you may ask yourself: what makes chips addictive? Scientists talk about hedonic hyperphagia or hedonic hunger. In plain English, it is the pleasure of eating, even when you are not hungry. There are certain foods that seduce you to overeat, and one of these are chips. Chocolate or candy can be other high-hedonic rating foods.

Erlangen experiments

A group of researchers from the Erlangen University in Germany set out to get to the bottom of this addiction eating. 17 healthy subjects with a body mass index of between 19 and 27 were recruited for eating experiments. They got either high calorie chips or low calorie zucchini. The chips created a marked stimulation on a functional MRI scan where the nucleus accumbens was lighting up. When they consumed zucchini no such stimulation could be documented. The researchers had done similar experiments with the same foods on rats. They too had functional MRI scans and the tests showed similar stimulation after the test animals consumed chips, but not after zucchini.

Nucleus accumbens, the addiction center for food

Professor Andreas Hess and his team in Erlangen say that the nucleus accumbens is the addiction center for food. They also did experiments with fat to carbohydrate composition to find the most addictive mixture. There is a certain fat to carbohydrate ratio that triggers food addiction. What surprised the Erlangen researchers was that both in rats and humans the optimal addiction potential was identical.

  • They found that rats preferred 35% of fat and 45% of carbohydrates in their chips. With humans there is the other factor: on top of the fat/carb mixture we like to taste some salt and spices, because this also will stimulate our appetite. The food industry has figured this out long time ago. This knowledge from tasting experiments is built into processed food.
  • The Erlangen researchers  also found that in obese people the nucleus accumbens was lighting up more intensely the higher the BMI was. That means that obese people are more food-addicted!

Triggering the nucleus accumbens

  • Professor Hess postulates that the 35% fat to 45% carb mix in potato chips is ideal for the body. It can mobilize quick energy from carbs, but also have storable energy from fat at the same time. It is this mix, which stimulates the addiction center in the nucleus accumbens.
  • In a study from Bethesda, Maryland researchers found an overlap between food addiction and drug addiction.  The common pathways in both is the release of dopamine in the nucleus accumbens. This dopamine release makes us feel good, and as a result, we want to experience it again.
  • In this study patients with bulimia nervosa were examined. They found that   overconsumption of sugar-laden foods had very similar effects as drugs in drug-addicted patients. It is the release of dopamine, glutamate and the opioid system that are involved in both. The nucleus accumbens is also receiving stimulation in both situations.

What can be done about food addiction?

This publication noted that people who are food addicted eat higher amounts of fat and carbohydrates. With this mix the feel-good nucleus accumbens produces most dopamine, which is the driving force behind the addiction.

  • If you cut out sugar, you find it easier to control your eating portions. But you also must cut out processed food, as this is where a lot of hidden sugar is coming from.
  • Cut down on your fat consumption. Even if you reduce it from 35% to 10% or 15%, this is a huge step forward. It reduces your calorie intake significantly, but also reduces the stimulation of your appetite center.
  • Eat lots of vegetables, salads and some fruit. Be careful with some fruit like grapes, bananas, mangos, papayas and dates. They are all higher in sugars. If you cannot entirely avoid those, use portion control, so you are not overeating on them.

Portion control

Besides changing the food quality, you can reduce the portions of food you are eating. Instead of mindlessly emptying a whole bag of chips, you could get a small bowl and fill part of the bag of chips into it. Remove the bag into a cupboard that is difficult to reach. If you are sitting and watching TV, you could eat one chip at a time, but only during commercial breaks. This way your chip eating becomes more conscious and more controlled, and you set a limit. In time you may find that you can replace the chips with a lower calorie food like slices of apples, celery sticks or carrot sticks.

What Makes Chips Addictive?

What Makes Chips Addictive?

Conclusion

Researchers found that chips were addictive in rats and in humans. Functional MRI scans of brains in rats and humans showed that potato chip eating stimulated the nucleus accumbens. It was lighting up in both species when the test subjects consumed potato chips. Surprisingly, it did not matter, whether these were test animals or humans! A review of several research papers showed a similarity between food addiction and drug addiction. It is dopamine and other brain transmitters that stimulate the nucleus accumbens, which is the addiction center. One of the keys, professor Hess from Erlangen University in Germany found, is the fat/carb mix. When the potato chips contained 35% fat and 45% carbs, this stimulated the nucleus accumbens.

Changing your eating habits

Knowing all of this helps us to be able to change our eating habits. To avoid the pitfalls of food addiction, cut out sugar and starchy foods, and remove processed foods from your diet. Also reduce some of the fat to 10% or 15% fat in your total diet. Eat lots of vegetables and fruit low in sugar. In addition you should also consider with portion control to avoid mindless munching. Before you know it you can shed the pounds that you may have accumulated before. You will be able to reduce your BMI to 21 to 23. Many people have done it before you.

Benefits Of Eating Nuts

By | fiber, food, heart attack, Heart Disease, Nutrition, omega-3 fatty acids, polyunsaturated oil, Stroke

You hear from time to time that there are benefits of eating nuts. But you don’t often see more details about it. I came across an article entitled “Nut lovers rejoice: Your favorite snack protects your heart”. It stressed that nuts prevent heart attacks. I will review some of this information here, but also touch on other aspects.

What nuts contain

Nuts contain fiber, unsaturated fatty acids, protein, vitamin E, folate and many minerals (zinc, potassium, magnesium). These ingredients have their own positive effects on your metabolism. For instance the fiber will lower cholesterol and triglycerides in your blood, which are risk factors for heart attacks. Vitamin E is a powerful antioxidant. Here is a review that shows why eating nuts makes a difference for your health. Despite all of the good that nuts do, you need to keep an eye at the overall quantity of nuts you eat. Nuts can contain up to 80% as oil, even though they are good oils. But the extra calories associated with the oil can make you gain some weight. When you add nuts to your diet you need to subtract some of the lesser quality saturated fats, so that your overall calorie balance does not change.

How do we know that nuts are healthy?

A British study from 2016 did a meta-analysis of people who ate nuts versus people who did not include nuts in their diet. 10 studies showed that eating nuts reduced mortality from all causes by 19%. In 5 studies where cardiovascular mortality was measured, a reduction of 27% was noticeable. Congestive heart disease in 3 studies showed a reduction by 34% when the patients consumed nuts. Stroke mortality was 17% less, as 3 studies showed. This is just an example of a few studies that show how effective supplementation of your diet by a few nuts here and there can be on the general mortality. It especially applies to mortality which is due to heart disease and strokes. Other effects of nut consumption are the reduction of atrial fibrillation, congestive heart failure and abdominal aneurysm (each by 15 to 20%).

Allergic reactions to nuts

A small percentage of people are allergic to various nuts. Nuts can cause a severe asthma attack, if the person has been sensitized to them in the past. They can cause angioneurotic edema in a small portion of people who may have inherited this condition. Tree nut allergies can cause anaphylaxis as is explained in this link.

The right dosage of nuts

This Australian website says that 30 grams of nuts, which is a handful of them would be the right dose per day. This is about 1 ounce per day. By including a variety of nuts your nutritional content will equal out. Some nuts have more calcium (almonds); others have more plant sterols (pistachios) or more fiber (pecans).

How bias can get introduced into medical literature

The Karolinska institute in Sweden analyzed the lifestyle and behavior pattern of nut lovers. Nut lovers were also into other healthy lifestyles: they smoked less than non-nut lovers. Nut lovers were leaner, physically more active and drank less alcohol.

They also ate more fruit and vegetables. Nut-lovers’ blood pressure was lower than the blood pressure of non-nut lovers. And people who consumed nuts on average had better education. Some of these lifestyle patterns can also protect the heart and contribute to less strokes. The researcher must be vigilant to control for the other lifestyle patterns except for the difference in the nut consumption when looking for the effect of nut consumption. If this is not done, there could be confounding, which introduces a bias into the final results.

Combine nut supplements and adopt a healthy lifestyle

This said, you know now about the results of good research. It is best to not be concerned about biases any more. For the average consumer it is important to apply what we know: use nuts regularly (about 30 grams per day, which is a handful). But it would not be a bad idea to adopt some of the other healthy lifestyles that nut eaters tend to have. In other words, exercise regularly, don’t smoke, cut out sugar, drink less alcohol and eat fruit and vegetables regularly. This way you will amplify the health promoting effect of the nut supplements.

Benefits Of Eating Nuts

Benefits Of Eating Nuts

Conclusion

We learnt that nut consumption is healthy. Only a small number of people who are allergic to nuts have to avoid them. The majority of people benefit from incorporating a small amount of nuts into their diet. Research has shown that it lowers mortality in general, lowers cardiovascular mortality and mortality from congestive heart disease. Eating nuts also reduced stroke mortality and lowers the risk of atrial fibrillation. When research is done, confounding factors like healthy lifestyles have to be controlled. But when an individual wants to reduce health risks, it does not harm to use healthy lifestyle factors along with nuts to reduce any risk. It will amplify the healthy effects of eating nuts.

What lowers LDL cholesterol?

By | blood test, Cardiovascular disease, cholesterol, exercise, fish oil, Fitness, food, heart attack, Heart Disease, Inflammation, Nutrition, Smoking, Stroke, Vitamins and supplements

Many times we hear terms like LDL and HDL cholesterol , but what lowers LDL cholesterol? We have to go back to a time when the ongoing Framingham Heart Study wanted to find out what caused a heart attack or a stroke. In the 1960’s scientists found out that cigarette smoking increased heart attack risk and also blood cholesterol. Then in the 1980’s the news came out that HDL (high density lipoproteins) reduced the risk of heart disease. Eventually several research institutions agreed that LDL (low density lipoproteins) was the culprit for causing plaque deposits in arteries. This caused heart attacks and strokes. LDL is often referred to as the “bad” cholesterol.

Clarification of HDL and LDL cholesterol

Recently a review article asked the question: “What is the difference between HDL and LDL cholesterol?”

Below I will review what LDL and HDL cholesterol do in our system. I will also mention normal values for blood tests. This will help you to understand your own blood test results. Then I will review what you can do to lower LDL cholesterol and to increase HDL cholesterol.

The function of LDL and HDL cholesterol

Total cholesterol in the blood contains LDL cholesterol, small dense LDL cholesterol and HDL cholesterol. The small dense LDL cholesterol is more dangerous than LDL cholesterol. It infiltrates the lining of the arterial walls aggressively. A normal LDL level is less than 100 mg/dL. When triglycerides, another form of lipid is high in the blood, LDL cholesterol forms a lot more small dense LDL cholesterol. This is the case in diabetics or in obese people. It is the reason why they are very vulnerable to develop heart attacks and strokes. The optimal range for triglycerides is less than 80 mg/dL.

HDL cholesterol is protective from hardening of the arteries and protects you from heart attacks or strokes. HDL dissolves LDL cholesterol, brings it to the liver, and the liver excretes it into bile. You want to have more than 60 mg/dL of HDL cholesterol in your blood.

Cholesterol math

The total cholesterol conventionally is calculated like this:

LDL cholesterol + HDL cholesterol + (triglyceride/5) = Total cholesterol

You see that the small dense LDL is not part of it here, but high triglyceride levels would increase the total cholesterol value as the inclusion of 20% of triglycerides in this equation compensates for this.

There is also a ratio of total cholesterol to HDL cholesterol that is important. This ratio should be below 3.4 for both women and men. This is also known as the ½ average risk for a heart attack or stroke. If your value is equal to that or below, you are in a very low risk category to get a heart attack or stroke.

Now I will deal with the question: what lowers LDL cholesterol?

What lowers LDL cholesterol?

Now we need to review what can be done to lower an LDL cholesterol which is too high. Don’t tell me that you want to take one of the statin drugs. These drugs have serious side effects and are only indicated for the most serious cases of high cholesterol values.

Most common measures to reduce LDL cholesterol

  • Cut out red meat

    First of all, cutting out red meat (like beef, pork and sausages) to an absolute minimum, for instance once per week or less is important. The reason is that these meats have more cholesterol in them and also more saturated fats than any other foods. Compare that to poultry, fish and vegetables like beans, which are healthy food sources.

  • Eliminate trans fats

    Furthermore, we need to eliminate trans fats as they are causing heart attacks. There is an important difference between ruminant trans fats and artificial trans fats. Ruminant trans fats have been part of the human diet for millennia like milk fat and fat from cows that are on pasture or lamb. Milk products for instance contain fat with 2-5% natural trans fats. 3-9 % of the fat in beef and lamb consists of natural trans fats. Studies have shown that the body is able to handle these natural trans fats, and heart attacks are not more frequent in people eating moderate amounts of these products including butter from cows that graze on pasture.

  • Artificial trans fats

    Quite the opposite is true for artificial trans fats in margarine that comes from vegetable oil. Avoid bakery items like sweet pieces or muffins and other products that contain hydrogenated oils. Read labels! Use olive oil or coconut oil, but avoid vegetable oils like corn oil, safflower oil or grape seed oil to get away from trans fats and unstable oils that turn rancid. Rancid oils contain free radicals that oxidize LDL cholesterol and attack the lining of your arteries through small dense LDL cholesterol.

  • Cut out sugar and starchy foods

    Another important item is to cut out sugar and starchy foods because these will raise your LDL cholesterol and triglycerides, which also leads to hardening of your arteries. Starchy foods are broken down by pancreatic juices into sugar, which enters your blood stream, causing an outpouring of insulin from the pancreas. When the short-term storage of sugar as glycogen is exhausted in muscle and liver tissue, the liver has to process any surplus of sugar that is still there. The end results are triglycerides and LDL cholesterol. Unfortunately the protective HDL cholesterol does not reach higher levels, when the LDL cholesterol is increased. A persistent diet of high-refined carbs will increase the risk for heart attacks and strokes. It follows from this that we are all better off cutting out sugar and starchy foods from our food intake as it will reduce LDL cholesterol and small dense LDL cholesterol.

  • Increase your soluble fiber intake

    Increase your soluble fiber intake by eating vegetables, oats and oat bran, lentils, fruits and beans. Why does this decrease LDL cholesterol? The liver tries to eliminate too much cholesterol by binding it to bile salts and excreting it into your small bowel. But the last part of the small bowel reabsorbs some of these bile salts, and from there they return to the liver. This is called the enterohepatic pathway of bile salts. Soluble fiber intake binds those bile salts and prevents re-absorption in the enterohepatic pathway, eliminating cholesterol safely in stool. Clinical trials have also shown that soluble fiber from psyllium, pectin, beta-glucans and others reduce LDL cholesterol by binding bile salts in the gut (interrupting the enterohepatic pathway).

  • Plant sterols and fiber supplements

    Plant sterols (usually sold as sterol esters) are recognized by the FDA as reducing the risk of coronary heart disease, if taken in high enough amounts (2.4 grams of sterol esters per day). There are other useful supplements like artichoke extract, pomegranate, soy protein, Indian gooseberry (Amla), garlic and pantethine (vitamin B5) that are beneficial in terms of prevention of heart attacks and strokes. It would be too lengthy to get into more details here.

  • Take a whey protein supplement

    There are two major milk proteins, whey and casein. Only whey protein binds to total and LDL cholesterol, lowering both. It is available in health food stores. Follow the package insert of the whey product for dosing.

  • Increase your omega-3 fatty acid intake

    Omega-3 fats naturally present in fish oils and nuts. They increase the amount of circulating HDL cholesterol, which binds the bad LDL cholesterol. Go ahead and eat salmon, herring and mackerel as well as walnuts, ground flaxseeds and almonds. You can also take molecularly distilled (or pharmaceutically pure) EPA/DHA supplements. This pure form of fish oil is free of mercury and other heavy metals. EPA stands for eicosapentaenoic acid or omega-3 fatty acid. DHA is the acronym for docosahexaenoic acid, an important supplement for the brain. Tests have shown that fish oil supplements at a dosage of 3.35 grams per day of EPA plus DHA reduce triglycerides by up to 40%, equally to Lipitor, but without the statin side effects. The end result: your total cholesterol/HDL ratio decreases, as does the risk for heart attacks and strokes. Here is a review of other oils in your diet.

Measures that will increase HDL cholesterol 

  • Eat foods with anthocyanin

    In a 24-week study with diabetic people HDL levels rose by 19% when food was eaten that was rich in anthocyanin. This consisted of eggplant, purple corn, red cabbage, blueberries and blackberries. The advantage of raising the HDL cholesterol level is that the total cholesterol to HDL ratio decreases, which lowers the risk for heart attacks and strokes.

  • Exercising regularly

    Exercising will increase your HDL cholesterol, which again decreases the ratio of total cholesterol to HDL cholesterol. This number should be between 1 and 3.5, the lower, the better.

  • Take a supplement called Ubiquinol, or Co-Q-10

    Adults above the age of 60 need 400 mg once daily, younger people need between 200 mg and 300 mg daily. Co-Q-10 prevents oxidation of LDL cholesterol, which would aggressively attack the arterial walls causing hardening of the arteries. What causes oxidation of cholesterol? The answer is clear: fried foods like french fries or deep fried chicken will lead to oxidation; other culprits are margarine, commercially baked goods and cigarette smoking.

  • Calcium and vitamin D3

    Recently a study on postmenopausal and overweight or obese women found that supplements of calcium combined with vitamin D3 lowered cholesterol.

  • Polyphenols

    Flavonoids are the largest group among the polyphenols in such common foods as vegetables, fruits, tea, coffee, chocolate and wine. Over 130 studies on humans have shown improvement of the lining of the arteries (endothelial functioning) and lowering of blood pressure. Polyphenol consumption has a connection to a lower risk of mortality from heart attacks. Eat a Mediterranean type diet or a DASH diet, and you will automatically get enough polyphenols with your food. However, resveratrol, the powerful red wine polyphenol, warrants a separate daily supplementation as it prevents LDL oxidation in humans (Ref.1). Take about 250 mg of resveratrol daily.

  • Niacin/ nicotinic acid

    This supplement comes as “flush-free niacin” and also as extended release niacin. It can raise the beneficial HDL cholesterol by 30 to 35% when patients take higher doses of 2.25 grams per day. In a metaanalysis of 7 studies researchers found a significant reduction of heart attacks and transient ischemic attacks. These are precursor syndromes before developing a stroke. Niacin can change the small particle LDL into a large particle size LDL, which is less dangerous. Niacin also reduces oxidation of LDL, which stops the atherosclerotic process. For a healthy person 500 mg per day of flush-free niacin is adequate.

  • Curcumin

    This is a powerful heart and brain protector combining three different mechanisms in one. It is reducing oxidative stress. But it is  also an anti-inflammatory. In addition it counters the process that threatens to destroy the lining of the arteries. One study on healthy volunteers showed reduction of 33% in lipid oxidation, a 12% reduction of total cholesterol and an increase of 29% of the protective HDL cholesterol when patients took 500 mg of curcumin for only 7 days (Ref.1). This is the daily dose I would recommend for prevention of heart attacks and strokes.

  • Vitamin E (tocopherols)

    This fat-soluble vitamin is an antioxidant and in the past health practitioners knew about its use as being heart supportive. Strangely enough some conservative physicians bad-mouthed this vitamin. In the meantime health practitioners have returned to using the vitamin. It turns out that there are 8 different types of tocopherols, with the alpha tocopherol being the best-known, but you also want to be sure that you are getting gamma tocopherol with your balanced vitamin E supplement every day. Newer research has shown that tocotrienol is more powerful than tocopherols. I take 125 mg of tocotrienols daily.

What lowers LDL cholesterol?

What lowers LDL cholesterol?

Conclusion

Over the years cardiovascular researchers have accumulated knowledge about supplements that will reduce LDL cholesterol or increase HDL cholesterol. It has practical value: you can look at your own lab results and choose what fits your situation best. You should always make these decisions together with your health care provider. None of the methods reviewed here have any serious side effects. On the other hand statins, as I have reviewed in the link provided, do have significant side effects. Keep in mind that cholesterol is a normal body component that our body needs to make human cell walls. But we do not need to smoke (stopping it lowers LDL cholesterol). We need regular exercise (increases HDL cholesterol). Keep your cholesterol and triglyceride values within the normal ranges that I listed and as a result you will do well in terms of preventing heart attacks and strokes!

Where Does Fat Go With Weight loss?

By | Anti-aging medicine, Cardiovascular disease, diet, exercise, Fitness, food, Nutrition, Obesity, Processed food, stem cells, telomeres, Weight loss

People often wonder where does fat go with weight loss? This question recently came up in a CNN conversation.  The answer was originally researched by Dr. Ruben Meerman and Professor Andrew Brown.

Dr. Meerman is an assistant scientist at the University of New South Wales and author of “Big Fat Myths: When You Lose Weight, Where Does the Fat Go?” Professor Brown is the head of the School of Biotechnology and Biomolecular Sciences at the same university.

When you lose 1 kilogram of fat, where does fat go with weight loss?

The interesting answer to this question is that fat gets metabolized. Dr, Meerman and Prof. Brown pointed out that originally Leifson et al. answered this question who used heavy oxygen and found out that this was metabolized into heavy water.

Technically these experiments are fairly complex, but they allow the researchers to see exactly where the body incorporates these chemicals and where they end up with breakdown of fat. The BMJ paper describes that the breakdown of 1 kg of fat follows the following pattern: It breaks down into 0.84 kg of CO2 (carbon dioxide) and 0.16 kg of H2O (water). In other words, the lungs are the primary organs that get rid of fat and the kidneys excrete the water. There is a bit of extra energy in this chemical reaction as well, which dissipates through the skin and through exhaled air.

What did health professionals think where the fat would go?

The health professionals were doctors, dieticians and personal trainers. About 65% of them thought fat would evaporate into energy/heat. About 10% thought fat would end up in the feces. 5% thought fat would turn into muscle. Another 5% thought fat would turn into sweat or urine. 8% were correct that fat would become CO2 and H2O. 7% said they did not know.

The chemistry of fat deposits and metabolizing fat

The body deposited triglycerides from the liver metabolism of sugar and fatty acids into fat cells and stored them as oleate (C18H34O2), palmitate (C16H32O2), and linoleate (C18H32O2). Part of this are many chemical reactions, including a number of enzymes. These fatty acids form esters and turn into gigantic molecules with this chemical formula: C55H104O6. The BMJ paper further says that an overall chemical description of metabolized fat would look like this:

C55H104O6+78O2→55CO2+52H2O+energy. In plain English it means that 1 molecule of fat ester (from fat storage) is metabolized together with 78 molecules of oxygen. This results in 55 molecules of carbon dioxide, 52 molecules of water and energy.

Fat turns into carbon dioxide and water

Based on this chemical reaction a calculation of the breakdown of fat into carbon dioxide and water was possible. The surprising result is that 84% of fat becomes carbon dioxide and only 16% of fat becomes water. We exhale the carbon dioxide from our lungs and it is mostly the kidneys that excrete the water. People who lose weight are aware that they have to urinate more often. But they do not notice that they get rid of a lot of carbon dioxide, as this is a subtle process.

Some observations from the fasting mimicking diet

The fasting mimicking diet (FMD) was at the center of the most recent anti-aging conference in Las Vegas I attended. This was the 25th Annual World Congress on Anti-Aging Medicine in Las Vegas, Dec. 14-16, 2017. Late in December 2017 I started 5 days of FMD and have just completed my 4th round of it (FMD is done 5 days out of each month). My main interest in doing this is to prevent heart attacks and strokes and I like the idea of stimulating telomeres for anti-aging and increasing stem cell production. See more details under this link.

Personal experience of fasting mimicking diet

I keep meticulous records of my body measurements using daily body composition scales, which I record in a booklet. Between March 23, 2018 and March 28 I lost 1.5 kg from 64.8 kg to 63.3 kg. Fat composition was reduced from 14.1% to 12.2%. Visceral fat was reduced from 6% to 5%. My muscle percentage rose from 38.1% to 39.1%. The basic metabolic rate was 1471 Calories on March 23 and went down to 1449 Calories on March 28. My body mass index went from 22.0 to 21.5.

I definitely noticed the frequent urination, something I had noticed in the past in 2001 when I lost 50 pounds over 3 months. Of course it is understandable when you reduce your daily calorie intake to 600 Calories per day that you will lose this amount of weight. People have different metabolisms. It may be that you won’t lose as much as I did.

What causes mainly weight loss?

There are many people who think that extra exercise would help you lose weight. But a publication has established that only about 8% of weight loss is due to exercising. 92% of weight loss is due to dieting.

Regular exercise is important for conditioning of your lungs, heart, muscles and joints. But to keep things in balance a reasonable diet, like a Mediterranean diet, should also be part of the regimen.

Sugar overconsumption

The obesity wave in the US started to take off between 1976 and 1980. 40 years later it is still rising. It is interesting to note that both wheat flour and sugar consumption in the US were increasing parallel to the rising obesity figures. In the 70’s the old-fashioned wheat has changed into the force hybridized Clearfield wheat, which is now 100% of the commercially available wheat. Clearfield wheat contains 7-fold higher gluten amounts than the old-fashioned wheat that your grandparents consumed. Gluten stimulates your appetite, so you crave more wheat and you crave more sugar. This becomes a vicious cycle.

Excess calories are stored as fat

The liver metabolizes sugar from regular food and from processed food into triglycerides and LDL cholesterol (the bad cholesterol that plugs up arteries). As I mentioned above, the body stores any excess triglycerides as fat and deposits the excess into fatty cells. You see from this that essentially sugar and wheat end up as fat deposits. I suggest you change your food intake into eating sensible food with fewer calories. Start by eliminating most of your sugar, wheat and processed food intake. This will help you to melt fat away as I showed with an example of my 5 day FMD.

Where Does Fat Go With Weight loss?

Where Does Fat Go With Weight loss?

Conclusion

I reviewed facts about the chemistry of melting fat away. The question is where does fat go with weight loss? In the process of weight loss fat breaks down into carbon dioxide and water. I also documented how you can lose fat in just 5 days (1.1 kilogram) on a 600-calorie diet and reduce the body mass index from 22.0 to 21.5.

Most people do not recognize the importance of watching their diet to achieve weight loss. 92% of weight loss occurs as a result of dieting. Wheat and sugar consumption have a direct connection to the obesity wave that started between 1976 and 1980. I have cut out all wheat, all sugar and all processed food in 2001. This allowed me to lose 50 pounds then and my body mass index today is 21.5. It can be done, even if you are 73 years old.

Prevent Plugged Arteries

There are several ways to prevent plugged arteries, which will translate into less heart attacks and strokes. The message is simple: if you get less heart attacks and strokes, you will live longer. Below I am examining ways to prolong life by various ways to prevent plugged arteries.

You probably heard of plaque formation in the arteries. This is the process where a combination of fat, calcium, cholesterol and cell waste forms a deposit (plaque) under the lining of the arteries.

The end result is that the blood won’t be flowing freely through the affected arteries. This can cause a heart attack or a stroke. Essentially, this is the point where a clot forms in the narrowed passage of the artery. It is also the point, when the clinicians make a diagnosis of a heart attack or a stroke.

Let’s examine what leads to plaque formation in the arteries.

Trans fats

Trans fats are contained in fried foods like French fries, in margarines and other butter substitutes. As margarine is a common ingredient of cakes, cookies, pastries and pies, these are all bad news for our heart health. I consider them off limits. If you eat those foods, you build up plaque in your arteries, which leads to premature heart attacks and strokes.

Lack of exercise

It has been common knowledge for a long time that being sessile leads to premature hardening of the arteries. In the late 1800s to the early 1900s physical exercise was promoted in various countries around the world.

The latter part of the 20th century saw a renaissance of the fitness movement. It was trendy to go running, cycling, and swimming or working out at a gym. It is not only trendy but healthy: cardiologists support all of these sports to help people stay healthy and keep the arteries free from plaque formation.

Too many refined carbs

Sugar and processed foods, especially those with added sugar to improve flavor, have a direct relationship to heart attacks and strokes. It is known that sugar causes high LDL cholesterol and high triglycerides. In addition sugar also causes inflammation of the arterial walls, which causes plugged arteries. However, sugar is only part of the problem. Starchy foods like rice, noodles, cakes, cookies and other foods made with flour get broken down into sugar. Both lead to insulin production. And both lead to changes of the lining of the arterial walls.

In the 1980s and 1990s there was a school of thought that a low fat diet would be healthy in terms of heart attack and stroke prevention (the low fat/high carb diet). This turned out to be a nutritional disaster: the high carb content of such a diet was the problem. It led to weight gain, obesity and death.

Red meat is a problem

Several studies have documented that saturated fat from red meat is only part of the problem. The other part is carnitine, which is abundantly present in beef, pork, lamb and venison. But mortality of people eating unprocessed red meat is only marginally elevated. It is when people eat processed red meat that there is a significant rise in mortality from heart attacks and strokes. This study examined this. They found that gut bacteria were stimulated by red meat to produce substances that stimulate bacteria in your gut to secrete TMA and TMAO, which makes your platelets more sticky and contributes to plugging your arteries. This research paper from the Cleveland Clinic explains it in more detail.

What must I do to prevent plugged arteries?

Eat the right food

A Mediterranean diet is anti-inflammatory. It contains lots of vegetables, but little red meat. Fish and chicken that contain much less L-carnitine are more dominant in Mediterranean food. As mentioned above, you want to avoid trans fats. And you also want to avoid sugar and too many starchy foods. This includes sugar-sweetened beverages. Making these changes will keep your insulin levels in the normal range eliminating inflammation in your arteries. Avoid eating processed foods, because they contain food preservatives and lots of sugar that we want to avoid. Eat more unsaturated fats like avocados, walnuts, olives, trout, herring, and salmon. The last three contain marine-derived omega-3 fatty acids that are particularly helpful in preventing heart attacks and strokes by being anti-inflammatory and by elevating the protective HDL cholesterol. Drink lots of green or black tea, rooibos tea, or ginger tea. They contain antioxidants and bioflavonoids that prevent plugged arteries.

Regular exercise

Many publications have shown that regular physical exercise will lower blood pressure, condition your muscles including your heart and lower mortality.

Only 10 minutes of brisk walking every day reduced the death rate by 33% compared to those who did not exercise at all.

Regular physical exercise does not only prevent heart attacks and strokes, it also reduces the risk of getting another 35 chronic diseases, as the link shows.

Here are some common exercises: jogging, cycling, running, brisk walking, swimming, playing tennis and doing aerobics. All of them will strengthen your muscles and condition your heart and lungs.

Other ways to prevent plugged arteries

Smokers must quit smoking, as smoking has been identified as a major risk factor for heart attacks and strokes.

Exposure to prolonged stress is a factor that leads to hardening of arteries. Stress management is possible by counseling, by self-hypnosis, yoga, tai chi and other relaxation methods.

Risk factors associated with plugged arteries

We already have mentioned the risk factors that are associated with clogged arteries. But for clarity I would like to repeat the major risk factors here.

  • Smoking
  • High blood pressure
  • Elevated LDL cholesterol (the bad cholesterol)
  • Reduced HDL cholesterol (HDL is increasing with exercise)
  • Obesity (often associated by ingestion of too many carbs)
  • Insulin resistance and diabetes
  • Lack of exercise (too much sitting in front of the TV or doing computer work)
  • Unhealthy diet (Standard American diet instead of Mediterranean diet)

Conclusion

We often think that we have no input whether or not we get a heart attack or a stroke. This is completely wrong. If you adopt the solutions I have listed here, you can change things for the better. You will reduce your risk to get a heart attack or a stroke. Treat high blood pressure. Stop smoking. Cut out sugar and starchy foods to reduce triglycerides and LDL cholesterol. Exercise regularly and your HDL will protect you from heart attacks and strokes. Shed pounds, if you are obese by starting a Mediterranean diet and cutting out sugar. This will also improve your insulin resistance or diabetes. Start daily exercise as this reduces your risk of a heart attack or a stroke. In addition exercise reduces the risk of 35 chronic diseases that have also been mentioned in one of the links.

Foods That Can Protect You From Cancer

By | alcohol, breast cancer, Cancer, diet, fiber, fish oil, food, lifestyle, lung cancer, Nutrition, Processed food, prostate cancer

There are foods that can protect you from cancer. Generally speaking you want to remove cancer-producing substances from your diet. But diet is only part of your lifestyle that can contribute to cancer. I will list some of the more important dietary factors below and briefly also touch on important other factors.

Avoid burning your meat 

When you use the BBQ, avoid burning your meat. As a matter of fact it is a lot better to use a slow cooker at low heat, and cook the meat for a longer time. In this way you won’t create carcinogens, which are cancer-producing chemicals. Healthy Grilling Tips to Minimize Carcinogens in Your Food. This is particularly important for the red meats (like beef, lamb, bison or pork).

Sugar can cause cancer

You never thought that sugar and an overabundance of starchy foods can cause cancer, but they do.  What is the reason for this? The answer is found in the metabolism of cancer cells. Cancer cells use 10- to 12-times more sugar for their metabolism than normal cells.  Over-consuming sugar is the worst thing a cancer patient can do. Replace sugar by stevia, which is a harmless sweetener. It does not lead to an insulin reaction. You need to avoid all other sugar substitutes as there are other health problems associated with them.

Avoid macaroni and cheese because of phthalates

Avoid macaroni and cheese: Phthalates are found in almost every sample of cheese powder used to manufacture macaroni and cheese. Phthalates can cause infertility and breast cancer. Toxic effects of the easily avoidable phthalates and parabens.

High fat diet

A high fat diet increases the risk for breast cancer: High-Fat Diet Increases Breast Cancer Risk, Study Finds. Limit your fat intake to about 10% of saturated fat. That is the recommendation of the FDA: New FDA Food Guidelines – Medical Articles by Dr. Ray. Increase your consumption of fish and seafood. Only one proviso: predator fish like shark, marlin, tilefish, swordfish and grouper are high in mercury. But wild salmon, sardines and oysters are low in mercury; so are shrimp and squid. Before You Buy Fish, Check This Mercury Level List.

Take high dose vitamin D3 supplements

In order to avoid cancer, take high dose vitamin D3 supplements to avoid cancer. Vitamin D3 in cancer prevention and therapy: the nutritional issue. Strong statistics exist showing that vitamin D3 is a powerful tool to lower your risk of developing cancer. Your family doctor should take a blood test called 25-hydroxy vitamin D level to monitor that you absorb enough vitamin D3. Some people absorb vitamin D3 slowly and fast absorbers absorb it more rapidly.  The only way how to find out how well your gut is absorbing vitamin D3, is by doing this blood test. It is now generally accepted that a good range of the 25-hydroxy vitamin D level is between 50 and 80 ng/ml.

Also curcumin 500 mg per day is good for cancer prevention. Turmeric | Cancer in general | Cancer Research UK.

Take enough fiber

Make sure you take enough fiber, which does not only reduce colorectal cancer, but also many other cancers. Foods for Cancer Prevention. North Americans are not consuming enough fiber. Vitamin D3 in cancer prevention and therapy: the nutritional issue.

Avoid processed meat

The World Health Organization has determined that processed meat is causing a lot of cancer. They labeled processed meat as a probable carcinogen. Processed meat causes colorectal cancer, pancreatic cancer and prostate cancer.

Moderate amounts of fruit and vegetables

Eat moderate amounts of fruit and vegetables. The claim in the past that fruit and vegetables would protect you from cancer is not as solid as it was thought of in the past. Newer research has shown that a basic intake of fruit and vegetables is needed for essential nutrients, but consuming more than that will NOT protect you from cancer. Fruit and vegetables and cancer risk. This is a case where eating more vegetables or fruit beyond a certain point will not do harm, but it will not protect you further from cancer.

Drink green tea or black tea

Drink green tea or black tea, sweetened with stevia for cancer prevention: Winter Beverages for Cancer Prevention. Green tea contains polyphenols and antioxidants. One of the antioxidants is called catechin, which prevents cell damage. The antioxidants help to prevent breast cancer, colorectal cancer and prostate cancer. In addition tea is heart healthy.

Avoid alcohol consumption 

Avoid alcohol consumption as much as possible to prevent cancer: Drinking Alcohol Really Does Raise Your Cancer Risk, Doctors Warn. We were indoctrinated by cardiologists that one glass of wine per day for women and two glasses of wine per day for men would be a prevention against heart attacks. But these relatively small amounts of alcohol do have an effect on causing cancer.  This British study showed that small amounts of alcohol indeed are cardioprotective. In contrast, these amounts and higher alcohol amounts can also cause cancer of the pharynx, larynx (voice box), esophagus, liver, breast, colon and pancreas.

Avoid too much red meat consumption

Beef, lamb and pork probably contribute to causing cancer according to the WHO. Use common sense, and eat more fish, chicken and turkey. Reduce your beef consumption. My grandmother said when I grew up in Germany that beef was a meal reserved for Sunday dinner only. The rest of the days we ate little in the way of meats, but lentils, beans, eggs or fish instead. Ask your grandmother, what she used to cook. Or ask your mother what she ate as a child.

Other lifestyle issues

Quit smoking, if you still do. This is by and large the biggest risk for developing lung cancer, throat cancer, esophageal cancer and pancreatic cancer. Watch your calorie intake: eat smaller meals more often. This way the production of your digestive juices will consume some calories and because you satisfied your hunger for foods, you will not gain weight. This will help prevent obesity and type 2 diabetes, both of which are established risks for developing cancer. Here is a review that shows you, which cancer types are caused by obesity: Obesity and Cancer . With regard to diabetes, there is a strong association with developing liver cancer, pancreas cancer and endometrial cancer (=uterine cancer). There is a lesser risk (only 1.2 to 1.5-fold) to develop colorectal cancer, breast cancer and bladder cancer. Diabetes and Cancer: A consensus report.

Pollution can also be a factor in causing cancer: How air pollution can cause cancer. If you can move to a less polluted city, do so.

Foods That Can Protect You From Cancer

Conclusion

As shown above there is strong evidence that certain foods can cause cancer. Others, including supplements like curcumin and vitamin D3, can help prevent cancer. If we avoid as many of the known cancer producing foods and eat more of the healthy foods that do not cause cancer, our cancer risk will decline significantly. In addition, if you quit smoking, avoid pollution as much as possible, reduce your alcohol intake and watch your calorie intake to prevent obesity and type 2 diabetes, you will move into the low-risk cancer group. We all need to work on this on an ongoing basis.
