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.

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.

Telomere Length A Telltale Sign Of Aging

By | Alzheimer’s disease, Anti-aging medicine, Arthritis, Autism, Cancer, Diabetes, Fitness, heart attack, Nutrition, Osteoporosis, telomeres, Vitamins and supplements

Dr. Sandy Chang gave a talk at the 22nd Annual World Congress on Anti-Aging Medicine in Las Vegas Dec. 10-14, 2014 entitled “Telomere measurement as a diagnostic Test in cardiovascular and Age-related disease”, but a shorter title would be “telomere length a telltale sign of aging” (my choosing).

Dr. Chang pointed out that it is now well established that telomere length is directly related to health. The shorter the telomeres are the higher the probability to get the following: early menopause, infertility, diabetes, wrinkles, arthritis, osteoporosis, cardiovascular disease, Alzheimer’s, Parkinson’s, dementia, cancer, stress and a lack of stem cells. In this BMJ study from 2014 it was shown on a large population basis that shorter white blood cell telomeres lead to a higher risk of coronary heart disease causing heart attacks. Decreased telomere length is also associated with the development of breast cancer, cancer of the ovary and uterus, cancer of the prostate and skin cancer.

Because of these connections it makes sense to determine a person’s telomere length. If it is short, do check-ups more often to detect any cancer early when it can still be treated.

Telomere length measurements are now done in many infertility clinics as short telomeres both in the male and female is associated with infertility.

The newest finding and perhaps the most important is that a healthy lifestyle, vitamins and supplements can elongate telomeres while a poor lifestyle leads to shortening of telomeres.

Here are the factors that lead to shortening of telomeres:

– Chronic stress

– Poor diet and nutritional habits

– Chronic inflammatory diseases

– Metabolic disorders

– Lack of consistent exercise/sedentary lifestyle

– Obesity, high BMI and body fat

– Smoking

– Over consumption of alcohol

– Lack of sleep / insomnia

When short telomeres are detected, it is important for the physician to look at lifestyle changes to protect telomeres from decreasing their length even further. This has the potential of preventing dementia and Alzheimer’s when it comes to brain health. It can prevent osteoporosis and metabolic diseases (diabetes, metabolic syndrome). Telomerase is the buzzword today, which is an enzyme that all of our cells have. The purpose why we have telomerase in our cells seems to be helping us build up and repair telomeres. Any substance that preserves telomerase or prevents the breakdown of telomerase will prevent shortening of telomeres and will also prevent the above-mentioned diseases.

These supplements lead to lengthening of telomeres:

-Vitamin C and E

-Omega-3 and polyphenols

-Vitamin A and D3

-All of these help controlling oxidative stress, reduce DNA damage, reduce inflammation and build up telomere length.

-A good diet and nutrition (Mediterranean type diet) will prevent telomere shortening as well and also lead to telomere lengthening.

-T-65, an extract from astragalus has been shown in vitro to lengthen telomeres, but there is no publication yet about in vivo effects in humans.

-Resveratrol is useful to prevent shortening of telomeres as well.

-Exercise also is a simple means to prevent telomere shortening.

Telomere Length A Telltale Sign Of Aging

Telomere Length A Telltale Sign Of Aging

Another talk on telomeres was given by Dr. Harvey Bartnof with the title “Telomere Shortening and Modulation: Case Studies From The Clinic”.

This talk was a comprehensive review of what is known about telomeres, about the fact that many diseases are due to telomere shortening, about animal experiments, ways of how to lengthen telomeres and finally some data on human studies with regard to telomere lengthening.

In the following I will briefly review all of these areas that were discussed. Some of this material overlaps with Dr. Chang’s lecture.

What produces telomere shortening? Dr. Bartnof showed 4 slides that listed all of the conditions and diseases that are associated with telomere shortening. Telomere shortening is associated with twice the risk to die from a heart attack when compared to people with normal telomeres.

a) Known genetic conditions in humans associated with telomere shortening

There are three known genetic conditions due to telomere shortening: A premature aging syndrome, called dyskeratosis congenitalis; patients with this condition die prematurely from cancer, or from bone marrow failure.

People with Werner syndrome who have a genetic telomere loss have a mean life expectancy of only 54 years.

Idiopathic pulmonary fibrosis is another genetic condition with shortened telomeres due to mutations.

b) Telomere shortening associated with these health conditions

Professor Elizabeth Blackburn, PhD who is one of the three researchers who won the Nobel Prize in Physiology and Medicine for their work on telomeres in 2009 stated the following: “Telomere shortness is associated with just about all the major diseases of aging… from cardiovascular disease, death from cardiovascular disease, risks of cardiovascular disease, diabetes, diabetes risks such as insulin resistance, vascular dementia, to osteoarthritis.”

An enormous amount of clinical investigations have been done since in cohort groups like people with diabetes, high blood pressure, obesity and cancer.

There is natural shortening of telomeres due to the aging process. When we compare telomere length of body cells of a 20-year old and call this 100%, the telomeres of a 100-year old person are on average only 40%. A study from the Karolinska Institute found in a group of matching twins where one twin had shortened telomeres, this twin had a 2.8 times greater risk of death than the twin with normal telomere length.

However, as already mentioned a number of other factors can lead to shorter telomeres like chronic stress in workers who look after Alzheimer patients, being of the Caucasian race (compared to African-American), having had less education, chronic unemployment, depression, pessimism, single people versus married people, phobic anxiety in women and hostility in men, poor sleep and too little sleep, migraine headaches in women, low physical activity, smoking cigarettes and alcohol consumption. The list does not stop here. Other conditions are associated with telomere shortening like heroin abuse, exposure to smog, polycyclic aromatic hydrocarbons and lead, cardiovascular disease, diabetes, cancers, osteoporosis, osteoarthritis, rheumatoid arthritis, cirrhosis of the liver, inflammatory bowel disease, chronic obstructive lung disease, Alzheimer’s disease, Parkinson’s disease, chronic kidney disease and disability in the elderly.

c) Effects of medications on telomere length

Antidepressants used against depression have a telomere lengthening effect, but NSAID’s, aspirin and interferon-alpha shorten telomeres. Other telomere shortening effects come from cancer chemotherapy.

d) Telomerase activation elongates telomeres

Successful experiments in various mouse strains showed that special strains that were telomerase deficient, could be reconstituted to normal by reinserting telomerase: atrophied organs regrew back to normal size and function. In humans it was shown that increased physical activity elongated telomeres, so did vitamin C, E and vitamin D3 supplementation, resveratrol, a Mediterranean diet, marine omega-3 fatty acid supplementation, higher fiber intake, bioidentical estrogen in women and testosterone in men, relaxation techniques like yoga and meditation. The Astragalus-derived telomerase activator TA-65 has been shown in animal experiments to elongate telomeres. The human data about TA-65 is still spotty or not available (it is also very expensive and may be unnecessary given the fact that so many other agents are known to lengthen telomeres).

e) Human data on telomere lengthening

Much can be achieved by changing one’s lifestyle: cut out toxins like cigarette smoking and alcohol abuse. Get involved in a regular exercise program, which has been shown to increase HDL cholesterol and to elongate telomeres. Adopt a Mediterranean type diet including olive oil; take vitamin E, D, C and supplements with resveratrol and murine omega-3 fatty acids, all of which elongate telomeres. Get enough sleep (7 to 8 hours per night) and do yoga and meditation. Avoid distress and tone down your stress level to eustress (normal stress level associated with every day living). An older person should use bioidentical hormones to replace missing hormones. All of this taken together will create a milieu in your body where telomeres get elongated and you live longer without disease. Several clinical conditions were mentioned where baseline telomere length was assessed initially and was found to be too short; simple lifestyle changes were then initiated, which were able to improve telomere length and treat these diseases successfully. In addition TA-65 (also termed T-65) was given in some of these cases, but in a subsequent discussion Dr. Bartnof admitted that he could not comment on how effective TA-65 by itself was as it was only one component of many other effective telomerase stimulators given. Till further research is out on this substance, it may be just very costly without spectacular benefits on its own.

Conclusion

I gave a summary of the talks by Dr. Chang and Dr. Bartnof regarding telomeres, but these were not the only talks about telomeres, although quite representative for the others. Both speakers pointed out how powerful lifestyle is for our body functions as this is what lengthens our telomeres and allows us to live longer, disease-free lives. Stem cells also have telomeres, but they are on average longer than the rest of the body cells (called somatic dells). An improved lifestyle will keep our stem cells in good shape, so they are there when needed to replace aging somatic cells.

The new logic of a healthy lifestyle is:

A healthy lifestyle causes healthy telomeres of somatic cells and of stem cells; this causes health until a ripe old age. In the next few weeks I will blog about more topics from the 22nd Anti-Aging Conference in Las Vegas. Stay tuned.

Forty Percent Of Premature Deaths Can Be Prevented

By | Cancer, Diabetes, Fitness, Health, heart attack, Heart Disease, High Blood Pressure, Lung Disease, Nutrition, Obesity, Prevention, Stroke, Vitamins and supplements

A new report from the CDC (Center of Disease Control) in the US has revealed that up to 40% of premature deaths could be prevented by simple lifestyle changes. As this link shows every year about 900,000 premature deaths occur in the US, which are due to 5 major diseases that in the opinion of the CDC can be prevented by 20 to 40%. Here are the diseases that kill: cancer, heart disease, COPD/emphysema, stroke and accidents/injuries. These conditions were responsible for 63% of all deaths in the US in 2010.

Let’s discuss each of these conditions and how one could lower the risk of dying from them.

1. Cancer:

The Framingham Heart Study has shown that smoking and cancer are closely related. Smokers who quit can significantly reduce their risk of getting cancer. We also know that exercise and prophylactic supplements like fish oil and vitamin D3 have cancer preventative effects.

Antioxidant supplementation that included beta-carotene, vitamin A, vitamin C, and vitamin E daily or on alternate days for 1 to 12 years, along with selenium supplementation reduced the incidence of cancer of the esophagus, colon, pancreas, stomach or the liver. Insulin resistance due to sugar and starch overconsumption is causing cancer, particularly breast cancer, colorectal cancer and endometrial cancer. I have discussed this in a recent blog.

Pollution has been linked to increased lung cancer risks as discussed here.

2. Heart disease:

Heart disease can be caused by several factors in combination. Lifestyle issues are important: Smokers need to quit smoking as the Framingham Heart Study has shown more than fifty years ago that smoking causes heart attacks. Obesity and diabetes also contribute significantly to the risk of heart disease. Often these are connected to faulty nutrition, which is another lifestyle issue that comes to mind when too much sugar and starchy foods are taken in; your liver will convert these into fatty acids, triglycerides and elevated, oxidized LDL cholesterol, which gets deposited under the lining of the arteries. A lack of exercise adds to this problem as a lack of exercise lowers the protective HDL cholesterol and fat is deposited under the lining of the arteries. Start exercising and your protective HDL cholesterol will rise, your total cholesterol to HDL ratio will lower to healthier levels and your risk for hardening of the arteries and for getting a heart attack will fall. If you have diabetes, it is important that you manage your blood sugars well; this means that if you inject insulin, you want the blood sugar tests to be within the normal range and the hemoglobin A1C values to be below 5.5%. Poorly controlled diabetes is an important cause of heart attacks and strokes. High blood pressure is also an important cause of developing heart attacks and strokes. It is important to control your blood pressure by taking blood pressure lowering pills and also by exercising regularly. Exercise seems to send a signal to relax the blood vessels thus lowering the blood pressure, which in turn prevents heart attacks.

3. COPD/emphysema:

Chronic obstructive pulmonary disease (COPD) or emphysema is mostly caused by chronic exposure to cigarette smoke from smoking. The earlier you can quit, the better your chances that your breathing will not be the limiting factor when you age. But it is also important to avoid exposure to other noxious gases, such as from welding and from exposure to pollution. This may involve a decision to move to a less polluted area. Or it might involve a job retraining. Those who are suffering from COPD can be helped to a certain extent by a portable oxygen tank with nasal prongs.

4. Stroke:

As mentioned before, quitting smoking, controlling high blood pressure and controlling blood sugar, if you suffer from diabetes have been shown to stabilize your blood vessels including the ones that supply your brain. The key is to prevent hardening of the arteries by a healthy lifestyle. Exercising and keeping your weight under a body mass index of 25.0 have been shown to be effective stroke prevention. Healthy nutrition as indicated above under “heart disease” is equally important for stroke prevention. Go green (eat more vegetables, consume more green smoothies), cut down grains, sugar and starchy foods and you will live longer without strokes and heart attacks. Remember, what’s good for your heart is good for your brain!

5. Unintentional accidents/injuries:

Wearing helmets when bicycling, wearing seat belts when driving in a car, avoiding risky behaviors are all measures that save lives. One factor stands out in all of this: if you drink too much, you run the risk of being involved in unintentional accidents or injuries. People may not like to hear this, but your brain lacks the natural inhibitory impulses when you are under the influence of alcohol, so you become more daring and you may not pay attention for the split second that could have prevented an injury or accident. People react very differently to alcohol. Some people feel inebriated after only ½ a glass of wine or beer whereas others can drink more before they make mistakes. The best is to be sober when you drive, ski, use power tools or walk in traffic. Even climbing ladders requires a clear mind!

Conclusion:

As the CDC said 20 to 40% of premature deaths (deaths that occurred before the age of 80) could have been prevented, if the above-mentioned recommendations were followed. Let me rephrase this: 180,000 to 360,000 premature deaths every year in the US before the age of 80 could have been prevented! Curative medicine cannot help with these statistics as a heart attack or stroke has happened when it has struck you. Cancer and end stage lung disease are similar conditions that you are suddenly faced with when they occur and unintentional accidents just seem to happen. This is where the importance of prevention can be seen, because these little baby steps every day are adding up to something formidable, a force to be reckoned with. Be part of the solution, think prevention!

Statins Can Hurt The Consumer

By | Anti-aging medicine, Arthritis, Diabetes, Fitness, heart attack, Heart Disease, High Blood Pressure, Hormones, kidney disease, Nutrition, Obesity, Prevention, Stroke, Vitamins and supplements, Weight loss

Lovastatin (Mevacor, from Merck) was the first statin drug approved by the FDA in 1987 as a cholesterol-lowering drug in the US. It made history in helping high-risk heart attack patients reduce their cholesterol levels and has helped safe many lives. But with the detection around 2002 that heart disease is an inflammatory disease, and that measuring the C-reactive protein with a blood test was a better than measuring cholesterol levels in predicting who would be at risk for developing a heart attack, the landscape has changed. Lifestyle changes have also been shown to be very effective in reducing cholesterol, C-reactive protein and triglyceride levels. In fact, lifestyle changes will reduce the risk for heart attacks and strokes. The newest flurry of activity with calls for putting more people on statins makes me suspicious that there could be a misrepresentation of the facts.

In this blog I am analyzing the literature to get to the bottom of the facts on reducing risk for heart attacks and strokes. I also come to my own conclusion.

Facts about cholesterol

Cholesterol is a waxy substance that is part of the cell walls and plays a vital role in our metabolism. Liver cell membranes, for instance contain about 30% cholesterol. However, most of the cholesterol in our body comes from metabolism, 20 to 25% from the liver, the rest in the gut, adrenal glands and the reproductive organs, and also from the brain (the myelin sheaths contain a lot of cholesterol). 50% of the body’s cholesterol is recycled through bile salts and reabsorption of cholesterol in the gut (called the enterohepatic pathway).

Cholesterol is vital for cell function, for insulation of nerve fibers (myelin sheaths) and for synthesis of our steroid hormones (sex hormones and vitamin D3, which  is now considered to be a hormone). The medical establishment took most of the information regarding heart attack and stroke prevention from the ongoing Framingham study. This clearly pointed to the importance of lowering the LDL cholesterol fraction (the “bad” cholesterol) and maintaining or increasing the HDL fraction (the “good” cholesterol). When it was realized that concentrating only on lowering cholesterol missed 50% of all heart attacks that researchers refocused and found the missing link, namely inflammation. Inflammation is at the cause of heart attacks and strokes, high cholesterol and lipids were only secondary phenomena. Ref. 2 points out that a comprehensive approach to treating a patient with high cholesterol should involve a combination of treatments aimed at the underlying risk factors for heart disease or stroke in a particular patient. This involves sophisticated blood tests where a metabolic derangement can be pinpointed. It should include measuring cholesterol fractions, lipids, the C-reactive protein, hormone levels and more.

Statins Can Hurt The Consumer

How the traditional thinking about cholesterol has changed

The Framingham study has provided the basis for the drug industry to produce statins until about 2002 when our thinking about cholesterol being the culprit for causing heart attacks has forever changed. Subsequently further research showed that other factors like inflammation of the blood vessels, the metabolic syndrome associated with obesity and lack of exercise were also to blame for causing heart attacks and strokes. Recently more details have come to light, which point to multiple causes like the consumption of too much sugar, too much trans fats, too much salt and eating too much over processed convenience food.  We end up gaining weight, develop the metabolic syndrome and inflammation of arteries (including the coronary arteries of the heart and the brain vessels). It is the lack of nitric oxide in the lining of the arteries, which combined with inflammatory substances from visceral fat are responsible for hardening of the arteries as the ultimate consequence of faulty nutrition and lack of exercise. We also know that oxidized LDL, particularly the very low-density lipoproteins (VLDL), will release free radicals and damage the arterial walls. CoQ-10 is a supplement, which is known to counteract this. One important test that had developed out of the Framingham study is the “ratio of total cholesterol to HDL cholesterol”, which is used by cardiologists to determine the risk of coronary artery disease. The average risk of this ratio for Americans is 5.0 for males and 4.4 for females. The ideal ratio to strive for is  the “1/2 average risk” ratio of 3.4 for males and 3.3 for women (Ref.2). A fit, slim person who eats a low carb, normal fat diet (modified Mediterranean diet) will often have a ratio of only 3.0, well below the 1/2 average risk. The moment you introduce grains in your diet (cereals, bread, pasta) your liver will convert carbs into LDL cholesterol, while HDL cholesterol will drop resulting in a high risk ratio of above 5.0 (often 7 or 8 or more). The LDL will get oxidized and is deposited into your arteries setting you up for coming down with a heart attack or stroke down the road.

How do statins work?

The statins are a group of drugs that inhibit an enzyme, called the hydroxymethylglutaryl–Coenzyme A (HMG-CoA), which leads to a lowering of cholesterol, specifically a fraction known as the LDL cholesterol. The success story of lovastatin (Mevacor) led to a flurry of new HMG-CoA reductase inhibitors (cholesterol lowering drugs) such as fluvastatin (Lescol), pravastatin (Pravachol), simvastatin (Zocor), atorvastatin (Lipitor), and rosuvastatin (Crestor) in the late 1980’s and the 1990’s. Collectively it is now a 26 billion industry in annual sales.

Later investigations showed that there were other mechanisms by which statins helped, namely they were found to decrease the inflammatory reaction, which can be measured by lowering of the C-reactive protein. However, there are significant side effects in about 1 to 3% of people who take this medication, particularly an inflammation of liver cells (evident from elevation of liver enzymes) and a myopathy, which is a painful muscle condition (Ref. 1). This latter fact, which can occur in as many as 33% of the population at large (particularly the exercise minded) has limited the use of statins in competitive athletes where myopathies can occur in as many as 75% of athletes treated with statins (Ref.2). The reason for that is that the muscles of athletes cannot keep up with the demands put on them when they are kept in check by the HMG-CoA reductase inhibitors. On the other hand statins have prevented heart attacks and deaths from heart attacks and strokes in about 25% to 35% of patients treated with them as many clinical trials have shown (Ref.1), but simple supplements that have no side effects can do the same or do even better (see below).

The lack of cholesterol synthesis by the body’s cells when statins are given, leads to an expression of more LDL receptors on the cell surfaces. LDL binds to these receptors and enters the cells, which removes the circulating high risk LDL fraction of cholesterol from the blood thus causing a drop in LDL cholesterol. All of the side effects of statins (pull down to side effects in this link) can be explained as a result of the slow-down of organ functions (brain, muscles, gut, adrenal glands, etc.) as cholesterol synthesis is reduced.

New information from the Framingham Heart Study

So far everything I said made sense. But when I came across Ref. 4 I noticed that there was a bombshell of new information from another follow-up study of the Framingham Heart Study (Ref. 5) that did not fit in with the latest marketing drive of the statin manufacturers. In this study from 2005 Boston researchers had studied the outcomes of 789 men and 1105 women over a period of 16 to 18 years with respect to cognitive function. Participants were divided into total cholesterol groups that showed levels that were desirable (less than 200), borderline (200 to 239) or high (above 240). The astounding results were that higher cognitive functioning as documented in multiple cognitive tests in these three groups showed the best performance in the group with the highest cholesterol and the worst cognitive test outcomes in the lowest cholesterol group, quite opposite of what was expected.

Another important piece of research (April 2013) comes from Spain where doctors followed a group of 7447 patients with a high cardiovascular risk who were put on a Mediterranean diet with olive oil, a Mediterranean diet with nuts or a regular diet. The end point was death from heart attack or stroke. After 4.8 years the study had to be interrupted as the Mediterranean groups showed a significant survival advantage over the group on a regular diet.

Ref. 4 cited literature evidence that statins cause a 48% increased risk in postmenopausal women who take statins to develop diabetes. It also cites compelling evidence that diabetes patients are twice as likely to develop Alzheimer’s disease within 15 years and are 1.75 times more likely to develop any kind of dementia in the same time period.

Dr. Seneff from the Computer Science and Artificial Intelligence Laboratory at MIT explains in great detail that statins effectively reduce cholesterol synthesis in the liver, which in turn starves the brain of one of its main nutrients explaining why patient develop Alzheimer’s disease and dementia as a result of statin treatment.

So, the lessons to be learnt from these clinical trials are that you want to offer your brain enough cholesterol and healthy fat to have a normal metabolism. Fortunately, what’s good for your heart is also good for your brain. Conversely avoid statins, if you can and try alternatives first. Ref. 4 explains that for years the experts had the wrong theory that low fat/high carb was what would be good for your heart and brain, but the opposite is true: what is good for your heart and brain is a high healthy fats/low refined carb diet.

Make sure that with your blood tests that fasting insulin is low (no insulin resistance), that the ratio of total cholesterol to HDL cholesterol is less than 3.4 (low risk for heart attacks or strokes) and that the hemoglobin A1C level is low (4.8 to 5.6%, ideally less than 4.5%), which means you are not diabetic.

How alternative treatment can save you from heart attacks

Lifestyle treatment through dietary intervention, moderate exercise, and weight loss has been somewhat neglected by mainstream medicine, but is now recognized in regular textbooks of medicine as first-line treatment (Ref. 3). Most patients can lower LDL cholesterol by 10 to 15% through a change in diet. High-risk patients with established heart disease (narrowing of coronary arteries) require a drop of 30 to 60% of LDL cholesterol; this high-risk patient group may need an addition of a statin. In patients with metabolic syndrome or diabetes high triglycerides are often present and will respond to decreased intake of simple sugars, alcohol, and calories (Ref.3). Total calorie intake should be adjusted according to what the weight is when weighed every day with the goal of reducing the weight when overweight or obese, but maintaining the weight when it is in the normal body mass index range (BMI of 20 to 25). The total fat intake should be around 25%-35% of the total calorie intake. Specifically, saturated fat needs to be less than 7% of total calories, polyunsaturated fat up to 10% of total calories and monounsaturated fat up to 20% of total calories. Healthy fats according to Ref. 4 are extra-virgin olive oil, organic butter, almond milk, avocados, olives, nuts, nut butters and cheese ( except for blue cheeses). Other healthy fats are sesame oil, coconut oil, and the oils found in seeds like flaxseed, sunflower seeds, pumpkin seeds and chia seeds. Note that trans-fats (such as in margarine and baked goods) are a “no-no” as it causes free radicals in your body, which would accelerate the hardening of your arteries. Complex carbohydrates from vegetables and fruit are the main source of total calories providing 50%-60% of the total calories. Fiber intake needs to be 20-30 grams per day. Protein intake should be about 15% of total calories. Fat should provide 25% to 35% of the total calories per day. Cholesterol intake should be less than 200 mg per day. You may want to consider the use of plant sterols (2 grams per day) to enhance LDL cholesterol lowering. Physical activity from moderate exercise should expend at least 200 kcal per day (better 300 kcal).

Which supplements prevent heart attacks and strokes?

There are several nutrients that have been shown to be powerful preventers of heart attacks and strokes. I will review them briefly here (based on Ref. 2):

1. Coenzyme Q10 (CoQ10): The cells lining the arteries are only working well when their mitochondria are working properly producing chemical energy in form of ATP. CoQ10 is an important component of the mitochondrial metabolism; it is also the only fat soluble antioxidant that gets absorbed into the LDL particles where it protects these from oxidation. Statins suppress CoQ10 synthesis, so patients on statins need to take CoQ10 supplements daily to counteract this. However, anybody who is healthy now should take CoQ10 as a daily supplement for prevention. I take 400 mg per day.

2. Vitamin E (tocopherols): this fat soluble vitamin is an antioxidant and has been praised in the past as being heart supportive, was subsequently bad-mouthed by some conservative physicians, but lately has been resurrected. It turns out that there are 8 different types of tocopherols, with the alpha tocopherol being the most known, but gamma tocopherol is the one you want to make sure you are also getting with your balanced vitamin E supplement every day as this is the one that is a powerful anti-inflammatory. Simply ask staff at your health food store for a vitamin E supplement with gamma tocopherol in it. Take 400 IU per day (of the mix).

3. Curcumin: This is a powerful heart and brain protector combining three different mechanisms in one; it is reducing oxidative stress, is an anti-inflammatory and counters the process that threatens to destroy the lining of the arteries. One study on healthy volunteers showed a reduction of 33% in lipid oxidation, a 12% reduction of total cholesterol and an increase of 29% of the protective HDL cholesterol when 500 mg of curcumin was taken only for 7 days (Ref.2). This is the daily dose I would recommend for prevention of heart attacks and strokes.

4. Polyphenols: Flavonoids are the largest group among the polyphenols contained in such common foods as vegetables, fruits, tea, coffee, chocolate and wine.  Over 130 studies have been done on humans showing improvement of the lining of the arteries (endothelial functioning) and lowering of blood pressure. Polyphenol consumption has been associated with 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.2). Take about 250 mg of it daily.

5. 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 higher doses of 2.25 grams per day are used. In a metaanalysis of 7 studies it has been shown to significantly reduce heart attacks and transient ischemic attacks (precursor syndrome before developing a stroke). Niacin can change the small particle LDL into a large particle size LDL, which is less dangerous. Niacin has also been shown to reduce oxidation of LDL, which stops the atherosclerotic process. For a healthy person 500 mg per day of flush-free niacin is adequate.

6. Fish oil (omega-3-fatty acids): Because heart attacks are due to an inflammatory process and high LDL cholesterol is thought to be only a secondary phenomenon, it is very important to have this additional tool of an important anti-inflammatory supplement. In the past it was still safe to eat fish fairly frequently per week. But with mercury, radioactive iodine from Japan’s leaking reactor and carcinogenic PBC’s all congregating in the ocean waters, it is no longer safe to consume fish in large quantities. The remedy to this situation is molecularly distilled (or pharmaceutically pure) EPA/DHA supplements. EPA stands for eicosapentaenoic acid or omega-3 fatty acid. DHA is the acronym for docosahexaenoic acid. Fish oil supplements at a dosage of 3.35 grams per day of EPA plus DHA were shown to reduce triglycerides by up to 40%, equally to Lipitor or even more effective, but without the statin side effects. The amount of the dangerous small dense LDL is also being reduced with fish oil. Fish oil supplements have reduced the mortality from heart attacks and strokes and led to a higher survival from non-fatal heart attacks. At the same time these preventative fish oil doses will also treat and prevent arthritis.

7. Other useful supplements: Soluble fiber from psyllium, pectin, beta-glucans and others have been shown in clinical trials to reduce LDL cholesterol by binding bile salts in the gut (interrupting the enterohepatic pathway). 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 have been proven to be of benefit in terms of prevention of heart attacks and strokes. It would be too lengthy to get into more details here.

Conclusion

Recently there was a review in a medical journal that demonstrated that clinical guidelines (in this case for clinical guidelines for lowering cholesterol) erred 40% of the times when measured against scientific tests as this link explains. When it comes to saving lives by preventing heart attacks and strokes, what is needed is a multifactorial approach that treats the multifactorial causes of cardiovascular disease. Just pushing for treating more people with statins as Big Pharma is attempting to do is not addressing the fact that cholesterol is needed for our metabolism and the synthesis of our hormones. It is much superior to use a combination of different approaches that overlap and thus potentiate each other in their effects excluding statins first. Exercise creates more nitric oxide production by the lining of the arteries, which opens up arteries and prevents spasms. A proper diet with as many of the proven vitamins and other support factors will control inflammation and oxidation of LDL cholesterol particles as explained. This will prevent heart attacks and strokes as has been shown in many clinical trials. Only patients who come from families with genetically high cholesterol or high triglycerides and those patients who had heart attacks and strokes should be exposed to statins as they are at a higher risk of developing a heart attack or stroke. They need all of the help they can get in addition to the lifestyle factors mentioned. Most other patients and the public at large will do quite well without statins (no side effects of diabetes, Alzheimer’s and muscle pains). And, yes, a diet high in healthy fats, but low in refined carbs is what your brain and heart need (the opposite of what you have thought, see Ref. 4).

Treatment For Alzheimer’s Failed, But Prevention Succeeds

By | Alzheimer’s disease, Fitness, Health, Heart Disease, High Blood Pressure, Hormones, Mental Health, Nutrition, Prevention, Vitamins and supplements

Recently another news story about a failed drug against Alzheimer’s disease (AD) went through the news media as shown in this link.

Donepezil, galantamine, rivastigmine and memantine are the most common drugs used to attempt to treat Alzheimer’s as this review explains. None of these drugs are a real breakthrough with regard to truly curing AD, as the drugs only achieve a few months of delay in the eventual deterioration of the AD patient’s symptoms. On the other hand there is an overwhelming accumulation of data in the last few years showing that many different factors can prevent AD and dementia. Below I am reviewing all these preventative factors and steps.

Genetic and epigenetic factors in Alzheimer’s disease

Early onset Alzheimer’s disease occurs between 30 and 60 years of age. It is due to a genetic predisposition (mutations on genes of chromosomes 1, 14 and 21). Only about 5% of all AD cases are caused this way. The remaining 95% of Alzheimer’s cases are due to late-onset Alzheimer’s disease. Here the causation is due to a combination of genetic, environmental and lifestyle factors. One genetic risk factor in this group is important, namely the apolipoprotein E gene (APOE), which is located on chromosome 19. There are several forms of APOE as this review explains. It also states that there is so much variation between the various APOE forms and even the worst form of this does not necessarily mean that the person who has this will come down with late-onset Alzheimer’s disease. So APOE is presently only used in research projects. Your doctor will only order genetic tests in people who have a strong family history of early onset AD.

There is another genetic marker, the CYP46 gene that was found to be present in some late-onset AD patients. If it is combined in a patient with the APOE gene, there is a much higher chance of developing AD as this review shows.

Epigenetic factors are probably more important than genetic factors for most cases of late-onset AD, as this review explains. Another review came to the same conclusion.

What are epigenetic factors? Exercising, replacing missing hormones, using a calorie restricted, only 15-20% fat containing diet; and taking supplements as listed below that will keep harmful genes in the “off” position and protective genes in the “on” position. Taking these preventative steps is probably more powerful than using any of the presently available medications mentioned above.

Treatment For Alzheimer’s Failed, But Prevention Succeeds

Treatment For Alzheimer’s Failed, But Prevention Succeeds

Exercise, diet, control blood pressure

As already mentioned, these are some of the powerful epigenetic factors that will prevent AD down the road. Controlling blood pressure has long been known to improve cognitive function. It is now evident that there seems to be a problem with microcirculation in brain tissue before it comes to neurodegenerative changes of AD and the underlying deficiency in nitric oxide production in the lining of the diseased arteries. Other research has shown that a lack of nitric oxide (NO) production is also the underlying problem with hypertension.

Green vegetables such as kale, spinach, also cabbage varieties and red beets are a source of nitric oxide and have also been shown to prevent AD at the same time.

Add to this exercise and you have a winning combination for the prevention of AD. You guessed right: exercise increases NO production from he lining of your arteries. When people age their lining of the arteries does not produce as much NO as in younger years. However, there is a supplement available, Neo40 Daily, that can be taken twice a day to compensate for this.

Here is another report about a 30% to 40% reduction in the incidence of AD when people do regular, simple exercises.

More good news about fruit and vegetables: tomatoes, watermelons, pink guava, pink grapefruit, papaya, apricot and other fruit all contain lycopenes, which have been shown to prevent AD.

Recently a new testing tool in combination with a PET scan of the brain has been developed, which may help the treating physicians to assess improvement or deterioration of an AD patient objectively using this method. However, this is still considered to be only a research tool at this time.

Supplements to prevent Alzheimer’s disease

The following brain-specific nutrients play a part in the prevention and treatment of AD (according to Ref.1):

1. B-vitamins: they are important to support the energy metabolism of brain cells.

2. Vitamin C: this has antioxidant properties and prevents brain cells and supportive glia cells from oxidizing.

3. Vitamin E in the form of mixed tocopherols: together with vitamin C has been shown to prevent Alzheimer’s disease

4. Phosphatidylserine (PS), with an intake of up to 300mg/day: counteracts and prevents memory loss.

5. Coenzyme Q10 (ubiquinone), 100mg/day (it would be safe to take 400 mg per day, which is also cardio protective): stabilizes the mitochondria of brain cells and heart muscle cells. It is a powerful neuroprotective agent and supports ATP production (energy metabolism of brain cells).

6. Ginkgo (Ginkgo biloba), at a dose up to 240mg/day: increases micro vascular circulation, neutralizes free radicals from oxidation and improves short-term memory.

7. Omega-3 fatty acid and DHA, 1500mg/day: has anti-inflammatory properties.

Other nutrients that hold promise are:

8. Huperzine A, 100 to 200mg/day: natural anticholinesterase inhibitor, derived from the Chinese club moss, surpasses donezepil according to studies by doctors in China

9. Vinpocetine, 2.5 to 10mg/day: comes from the periwinkle plant, increases cerebral blood flow and stimulates brain cell metabolism

10. Turmeric extract (curcumin) is very beneficial in reducing tau protein deposits in AD.

All these statements and dosages are cited from Ref.1.

Hormones to prevent Alzheimer’s disease

According to Ref. 1 there are certain hormones that can prevent AD: DHEA, pregnenolone, estrogen (bioidentical estrogen only).

  1. DHEA is persistently low in AD patients and replacement with DHEA at 50 mg daily has shown improvements in muscle strength and energy of AD patients.
  2. Pregnenolone has been shown to be a powerful memory enhancer in animals and humans alike.
  3. Estrogen, if taken as bioidentical estrogen cream (Bi-Est) can improve brain function. Estrogen is a strong epigenetic switch that keeps a woman mentally younger for longer, but has to be balanced with bioidentical progesterone cream to prevent breast cancer and uterine cancer. A study showed that estrogen replacement early in menopause will cut down on the heart attack rates, but it is also known, particularly when given as bioidentical hormone cream to prevent AD.
  4. In addition progesterone has been described to be of value in the aging woman to preserve brain metabolism.
  5. Testosterone is known to protect against Alzheimer’s disease in the aging male.
  6. Melatonin at a starting dose of 1 mg to 3 mg at bedtime often helps to restore the disturbed sleep pattern, but also augments the effects of the other hormones (Ref.1).

Removal of toxins, particularly mercury

Mercury is extremely toxic in minute amounts and affects brain cells preferentially. Intravenous vitamin C/glutathione treatments as described in this blog will remove mercury from your system including the brain.

It may take 20 to 30 such treatments in weekly intervals followed by a maintenance program every two to three weeks to remove mercury from the body.

Other heavy metals can accumulate in the brain as well and must be removed. This is described here in more detail.

Conclusion

There have been major breakthroughs in prevention of Alzheimer’s disease and dementia over the past few years, many unnoticed by the media. The search is still on for an effective drug that would treat AD when it is present. However, this may be 10 or 15 years away and we cannot afford to wait that long. Instead I suggest that people should embrace the concept of preventing AD by using as many of the factors described above. Both at the 2011 and the 2012 Anti-Aging Conferences in Las Vegas several speakers pointed out that a combination of several preventative factors will be much more effective than one factor alone and they estimated that about 80% of AD could be prevented this way.

Macular Degeneration Risk Less With Vitamins

By | Eye Diseases, Nutrition, Vitamins and supplements

Age related macular degeneration (AMD) is one of the more frequent reasons for loss of vision in the ageing population. The disease is also the most prevalent reason for blindness in developed countries.
A group of researchers from the Netherlands made it their mandate to investigate, in which proportion antioxidants were useful in the prevention of AMD. Supplementation with vitamins C, D and E was used and also beta-carotene and zinc. The observations were made using questionnaires from the Rotterdam Study (1990-1993).

The group on which the research concentrated consisted of inhabitants 55 years of age or older living in a middle class suburb of Rotterdam. Of 5836 at the baseline with a risk of AMD 4765 had reliable data of their dietary habits. At the end of the study 4170 participated in the follow up.
Dietary intake of vitamin E and zinc was inversely associated with the development of AMD: the group with an intake of vitamin E and zinc had less macular degeneration than those whose diet was deficient. A higher than median intake of all the four nutrients, vitamin E, zinc, vitamin C and beta-carotene showed even more benefit. The risk to develop macular degeneration was reduced by an impressive 31 %.

These results are of importance to the ageing population and the elderly. A high dietary intake of the four nutrients is important in the risk reduction of age related eye diseases like AMD.

Not All Vitamins Prevent Cancer

By | Cancer, Nutrition, Prevention, Vitamins and supplements

Even in the recent past, vitamins were looked at as an essential weapon to prevent illness, however, a large study by the Cochrane Hepato-Biliary Group at the Centre for Clinical Intervention Research at Copenhagen University has come up with disappointing evidence.

A large evidence-based analysis was performed involving a population of 170,525 persons who were enrolled in randomized trials. They received a regimen of antioxidant supplementation that included beta-carotene, vitamin A, vitamin C, and vitamin E daily or on alternate days for 1 to 12 years, along with selenium every year for 2 to 4 years.
All trials reported the separate or combined incidence of cancer of the esophagus, colon, pancreas, stomach or the liver.
Results showed that beta-carotene alone, the most widely tested antioxidant for cancer prevention, did not have substantial cancer-fighting properties in gastrointestinal cancers. The devastating blow is the fact that beta-carotene in combination with vitamin A and vitamin C significantly increased mortality! Recent studies examining vitamin C show, that it can be an antioxidant, but it also can be a pro-oxidant (the less desirable quality). Trials involving selenium very clearly showed that it might have beneficial effects on the incidence of gastrointestinal cancers.
Following these news it would be a grave mistake to assume, that fruit and vegetables with their built-in antioxidants, micronutrients, dietary fiber and beneficial plant-chemicals have fallen off grace.

Not All Vitamins Prevent Cancer

Not All Vitamins Prevent Cancer

The truth is, that fruit and vegetables typically contain safe levels of vitamins. Most studies have reported that adequate intake of fruit and vegetables are indeed associated with a low incidence of cancer.
The study, however, clearly points out the pitfalls of vitamin supplementation.
-“The more the better” does not apply when it comes to taking vitamins.
-Antioxidants according to this study are not as beneficial for cancer prevention as was thought of in the past.
– Only vitamin C and selenium held up to the scrutiny of the evidence-based researchers with regard to having preventative effects regarding the above named gastrointestinal cancers.

Vitamins C And E – A Weapon Against Alzheimers

By | Alzheimer’s disease, Nutrition, Vitamins and supplements

A study in a recent edition of the Archives of Neurology reports about 4740 patients from Cache County, Utah, who were 65 years or older and were followed over 5 years. At the start it was found that those who had taken vitamin C and E on a regular basis as separate supplements had a 78% lesser risk of developing Alzheimers (correct medical term: “Alzheimer’s disease”).

5 years later out of 3227 survivors who were at risk 104 more people had developed Alzheimers, but 64% of those who combined vitamin C and E as a supplement did not develop Alzheimers. Dr. Peter Zandi from the Department of Mental Health, Bloomberg School of Public Health, The Johns Hopkins University/ Baltimore, Md was the lead author of this study. He stated that this was only an observational study, but that the data was convincing enough to warrant a full-scale controlled trial to examine the value of anti-oxidant agents (such as vitamin C and E) as a preventative against Alzheimers. There were a number of built-in controls such as vitamin C alone, vitamin E alone and multiple vitamins (including vitamin C and E in smaller dosages) that were all ineffective in preventing Alzheimers. The daily dosages that were necessary for the protective effect were vitamin C 500mg to 1000 mg or more per day as well as 400 IU to 1000 IU of vitamin E per day. The U.S. recommended daily allowance was insufficient for the protective effect. These dosages typically are in the order of 22 IU of vit. E and 75 to 90 mg of vit. C. Vitamin B complex alone was also ineffective in protecting against Alzheimers.

Vitamins C And E - A Weapon Against Alzheimers

Vitamins C And E – A Weapon Against Alzheimers

Comments: There are many unanswered questions about Alzheimers, but this paper gives valuable hints in terms of the protective effect of two vitamins (vitamin C and E taken as separate supplements daily). There are other factors such as genetic ones and perhaps a dysregulation of the cholesterol brain metabolism that lead to the production of a glue-like substance, called “beta-amyloid” ,that causes memory loss in Alzheimers patients. Testosterone has recently also been noticed to be important in the prevention of Alzheimers disease. In addition to these vitamin supplements a low glycemic, low fat diet would likely be very beneficial together with a regular exercise program and calorie restriction to prevent Alzheimers disease in many patients (prevention of the metabolic disease).
