Keep Your Muscles In Older Age

By | Fitness, fractures, Health, Heart Disease, Men's Health, Obesity, Women’s Diseases

Intuitively you may have noted that older folks who have very little “meat” on them are not as healthy as people of the same age with well-developed muscles.

A research team under the supervision of Dr. Preethi Srikanthan and Dr. Arun S. Karlamangla from the David Geffen School of Medicine at UCLA, Los Angeles, CA decided to measure the muscle mass index instead of the body mass index. They did this using bioelectrical impedance (simple electronic body composition bathroom scales) and they wanted to see whether there would be any correlation with regard to mortality statistics in an older population.

The study group consisted of 3659 participants from the National Health and Nutrition Examination Survey III (average age for males 55 and older, females 65 and older). The survey took place between 1988-1994. Mortality rates were computed by the end of 2004. The median length of follow-up per person was 13.2 years.

The authors of the study compared mortality curves for four subgroups of muscle mass from low to high: 0-25%, 25-50%, 50 to 75% and 75 to 100%. When the lowest muscle mass group was compared to the highest muscle mass group, there was a 20% increased mortality rate for the lowest muscle mass group.

This study had careful controls built in and could demonstrate that the difference was not due to better or worse LDL cholesterol values or triglycerides; it was not due to differences in diabetic rates or other factors. This is the first study that shows in a US based population that a lower than average muscle mass is an independent risk factor for premature death in an older population.

The authors were aware of Danish study that had previously shown that a lower muscle mass was associated with a higher mortality rate in 50 to 64 year-olds.

I like to comment regarding this study by putting it into the context of other medical findings.

Keep Your Muscles In Older Age

Keep Your Muscles In Older Age

1. Older people tend to have more falls

Several studies have shown over the years that older people fall more often because of a combination of balance problems with slower reaction time, and also because of poorer muscle development when compared to a younger age group. The medical costs are staggering when older people reach the age of 85 where about 20% of that subpopulation experience serious falls resulting in hip fractures and hospitalizations. There is a mortality of about 25% associated with hip fractures in that age group. And about 50% of those who survive will not be living independently at 1 year following a hip fracture. Fortunately fractures from falls can largely be prevented by making physical changes to the home to prevent tripping and having extra guard rails where needed. But another important factor is to exercise regularly within the capabilities of the older person to maintain muscle mass, which will balance the body and control upper and lower extremity strength as the person moves around.

2. Fit people live longer

A Stanford University study followed 6000 middle-aged men for 10 years and found that the fittest who exercised regularly were 12% more likely to stay alive for every metabolic equivalent; this is the energy that a sitting person uses in terms of oxygen consumption. They also found that the least fit had a 4.5-fold higher death rate within 6 years from the beginning of the study compared to the fittest.

To put this into perspective: a regular walk at less than two miles an hour would be equivalent to 2 metabolic equivalents, a brisk walk at 4 miles per hour is worth 5 metabolic equivalents and running 6 miles an hour is worth 8 metabolic equivalents. This is how the math works: a regular walk every day translates into 2×12% = 24% more likelihood of staying alive in the next 6 years compared to a sedentary person. A person exercising with a brisk walk with a speed of 4 miles per hour every day would be 5×12% = 60% more likely to be alive in 6 years compared to a sedentary person who does not exercise. Not smoking and having a normal weight would add to your probability of living longer. Pushing yourself to the extreme (running 6 miles per hour) may be problematic for the majority of us as there are issues of getting into adrenal gland insufficiency that can develop, if you over-stress yourself. (This is my comment, not part of the study).

Now you may have wondered about the woman’s side (as the previous study was an all-male study). The answer comes from a recent paper that studied 10 clinical trials throughout the world (US, Denmark, Germany, Sweden, Taiwan and Japan) involving only postmenopausal women. Yes, there is the same surprising finding that regular brisk exercise makes the women live longer with less disabilities and less mortality!

The bottom line: exercise regularly and live.

3. Exercise develops your muscles and maintains them

We were born to use our muscles daily (designed as hunter/gatherers), but in the meantime this is what we do: sitting in front of the computer or TV, in cars, in class (school, university, work) or in the movie theatre. So we need to discipline ourselves to get into a routine that balances all of the other activities. Muscle strength exercises or activities as indicated in this link are the answer.

The earlier we adopt this type of a routine, the better off we are when we reach the golden years of retirement. I am one of the examples of former non-exercisers. Apart from liking to go for long walks 3 to 4 times per week I did no formal exercises until 8 years ago when my wife and I got into ballroom and Latin dancing inspired by “Dancing with the stars”. But it is only about 2 years now that we took up regular gym workouts for 45 to 60 minutes every day. It is now easier for me to walk up on a steep hill in our neighborhood that has an 18% incline than 2 years ago.  Muscles need regular exercise. You put a limb in a cast and within 3 weeks most of the muscle strength has melted away. You remove the cast and it will take 3 to 6 weeks of regular exercise to regain the muscle strength. So why not maintain your muscle strength in the first place?

4. Exercise develops cardiovascular fitness

The aerobic part of my daily exercise program (treadmill) develops cardiovascular fitness as the lungs have to work harder and the heart is being activated. Doing this regularly is mimicking going through the landscape looking for food and hunting.  Of course most of us drive in our cars to the grocery store and get our food that way. So my balance is to go to the gym and at least once a day get that work-out. What can we expect from fitness training? An NIH study showed that with a moderate work-out of only 2.5 hours per week you will gain 4.5 years of life due to cardiovascular fitness. This is better than money in the account. It is free healthy additional life!

5. Sensible nutrition will help preserve muscle mass

No, I am not taking your food away. I am suggesting that we watch the quality of the food we are consuming. If you are like the average consumer, you may be eating too many carbs in form of pasta, bread, rice and potatoes. Some of you have read in past blogs that my wife and I cut out sugar and starchy foods as well as wheat since 2001. We both lost 50 pounds and kept it down. I know that if I would restart sugar and starchy foods, my fat content would go up, my muscle content down and the BMI up. How do I know? I weigh myself every day on body composition scales (which works by the principal of bioelectrical impedance analysis), which show all of these indicators. Recently I got into some organic Bing cherries. They were delicious, but it also is a fruit with significant sugar content! Within a day I knew that I’d better watch the quantities I consume (fat composition was up, muscles mass down). It took 3 days for my values to be back to normal.

When it comes to muscle mass, overconsumption of refined carbs is one problem; however, our bodies do need quality lean meat and some fish (salmon, mackerel; low mercury fish) as a source of protein. I buy organic meats to get away from the problem of pesticide pollution as much as possible. Some people like vegan food, they may need to supplement with protein supplements.

Conclusion:

It may sound like common sense that a body with well-developed muscles will live longer. You may want to compare this to a well-maintained car (less rust, good maintenance) and the car will still drive well once it has a high mileage.

We have bodies that need maintenance (exercise) and good nutrition (no junk food, sensible diet). If we make this our regular lifestyle, we will develop and maintain muscles. It will keep us in the group with a lower mortality rate compared to sessile persons and junk food consumers.

Nothing happens without any effort. We need to earn muscle fitness for ourselves! Think about it, improve where you need to improve and then maintain it. More than anything else this will pay dividends well into your future.

Sunburn Prevention

By | Cancer, Health, Prevention, Skin Disorders, Vitamins and supplements

Much has been written about sunburn prevention. The thinking behind this is that perhaps we could prevent skin cancer and melanoma development, if we would block ultraviolet rays from the sun or from tanning booths irritate our skin.

So far the theory. Now the truth.

1. Increase of skin cancer despite sunscreen applications

It is sobering that statistics of skin cancer frequency  show that despite more awareness of the importance of skin protection with sunscreen lotions and creams, skin cancer rates have steadily increased. Behind this paradox is the fact that vitamin D3 production in the skin is blocked from sun exposure and the person is not getting the cancer protecting effect of vitamin D3.

Low vitamin D3 levels (measured as 25-hydroxy vitamin D3) are not only associated with skin cancer, but also with breast cancer, and breast cancer will be reduced to 50% of control groups, if patients are treated with high vitamin D3 supplements. There are many other cancers that respond to exposure to sunlight or to supplementation with vitamin D3.

2. We need to know about infrared rays and the ultraviolet exposure

The ultraviolet radiation of sunlight has been extensively studied. There are UVA rays that range from 315 to 400 nanometers. They make up about 95% of the sunlight and penetrate deeper into the skin (the dermis level) leading to more severe skin damage, producing aged looking skin.  UVB rays (5% of sunlight) contain wavelength measuring between 280 and 325 nanometers affecting the most superficial layer of the skin, the epidermis. These rays cause sunburns. Both UVA and UVB are strongest around midday. The sun also produces UVC rays (wave length 180 to 280 nanometers), which are completely absorbed by the ozone layer and are not of importance unless you live under an ozone hole.

Next there is IR (infrared radiation), which has only recently been detected to be of health concern. IR rays range from 760 nanometers to 1 million nanometers (=1 millimeter). It causes skin photoaging and damage. Most of IR is in the lower range (between 760 and 1,440 nanometers); the total amount of IR rays that reach the skin is massive compared to the UV light and 50% of these rays reach deep into the skin to the level of the dermis.

Sunburn Prevention

Sunburn Prevention

3. Filtering out the damaging rays

Armed with the above knowledge we can now talk about sunscreen lotions and sunscreen creams. Traditional sunscreen lotions and creams have been directed against both shortwave (UVB) and longwave (UVA) rays of the sun. UVB blockers prevent damage to the surface of the skin (epidermis level), UVA blockers prevent damage to the deeper dermis. It is in your interest to buy a sun blocking agent that blocks both of these rays. (You have to read labels.)

However, both of these blockers, which means all of the traditional sunscreen agents, will not block IR waves (infrared radiation), which causes most of the wrinkles, age-related skin changes and skin DNA damage, which eventually results in skin cancer.

4. Vitamin D3 deficiency because of sunscreen applications

As we know that sunscreen agents lead to blocking of vitamin D synthesis in the skin, it is prudent to take vitamin D3 5,000 to 10,000 IU per day and have your health care provider order 25-hydroxy vitamin D3 blood levels from time to time (aim for a level of 100 ng/m or more). There is no danger of overdosing vitamin D3. That story about overdosing of vitamins is coming from vitamin A overdosing. There is a ceiling not to be exceeded due to liver toxicity over vitamin A overdosing, but not so for vitamin D3. Vitamin D3 protects not only from skin cancer, but also from other cancers. For more on vitamin D3 read my recent blog on this.

5. Whole body protection from the inside

There are two approaches to using systemic natural extracts. One component is from a tropical fern (Polypodium leucotomos) and another one from blood oranges that can both repair sun damaged skin and prevent sunburn. The effective substances are administered orally.

This fern extract has been tested in smaller clinical trials and was found to have a 70% to 75% efficacy in blocking all sun rays from the inside out.

In a small trial patients were exposed to UVB light after preparation with red orange extract and a 35% reduction of sun burn was found within 15 days when compared to controls.

There is a possibility now to take one capsule with tropical fern extract mixed with red orange extract and combine this with traditional sunscreen agents and have optimal sun protection.

One trial that is mentioned in these last two links is a group of polymorphous light eruption patients who are born with extreme sun sensitivity, but reported an 80% improvement with this oral fern extract treatment.

6. Final recommendations for sunburn prevention

Although the advice given in this WebMD link is useful, it neglects to recommend to supplement with vitamin D3 because of the sunscreen action. It also does not mention the IR waves of the sun that do most of the damage and that only get prevented by staying out of the sun or by taking the oral sunscreen pill (tropical fern extract and red orange extract mixed).

My recommendation, if you were not allergic to ferns, is to consider taking the oral pill (as far as I know currently only available from LifeExtension as “enhanced fern block with red orange complex”) to block the entire wavelength of the sun rays. This will repair some of the skin damage that has already been done. Follow the above WebMD link as well with regard to the sun screen lotions/creams. Also stay out of the noon sun between 11 AM and 2 PM. Take your vitamin D3 in the high dose range as discussed above to preserve optimal resistance against all kinds of cancers including skin cancer.

Conclusion:

In reviewing the facts prior to writing this blog I was quite bewildered how misleading a lot of the literature is regarding prevention of sunburns, particularly by assuming that all you had to do was to block UVB and UVA rays. I attempted to explain why this is an oversimplification, and the skin cancer statistics clearly show that sunscreen blockers alone are not stopping skin cancer. So, we do need a combination of
1. Staying out of the noon sun.

2. Using clothing and wide sun hats to keep the sun out of our faces.

3. Use the traditional sunscreen agents. Reapply, if necessary.

4. Using an oral sunscreen agent that blocks infrared rays as discussed under point 5 and 6.

5. Using vitamin D3 in high doses as discussed under point 4 above for cancer prevention.

With this in mind, enjoy the rest of your summer!

Older Grumpy People Have Higher Risk Of Dementia

By | Alzheimer’s disease, Anti-aging medicine, Health, Hormones, Men's Health, Women’s Diseases

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

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

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

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

Older Grumpy People Have Higher Risk Of Dementia

Older Grumpy People Have Higher Risk Of Dementia

Women’s Health Initiative:

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

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

Problems now for HRT:

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

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

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

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

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

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

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

Hidden benefits of bioidentical hormone replacement:

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

Conclusion:

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

Industry Sponsored Diet Soda Study Deceptive

By | Health, Hormones, Nutrition, Prevention, Vitamins and supplements, Weight loss

Recently an industry sponsored study was reviewed by the media with this headline: “Diet soda helps weight loss, industry-funded study finds”. Before you get too excited about this study, let me tell you that you are being deceived. Essentially the study compared 150 overweight or obese people on water and a similar group of people on diet sodas. Both groups were counselled on the benefits of exercise and a healthier diet. At the end of 12 weeks the water group that did not drink diet sodas had lost 9 pounds, while the diet soda group that continued their former habit lost 13 pounds. The question now is why this 4 pound difference? The sponsor of the study would like you to think that the soda diet drink is healthier, because it helps you to lose weight. Let me explain to you that there are a few flaws in the study as follows.

1. Most often there are confounding errors in industry-sponsored studies. Even though it looks on the surface that the two groups were comparable, researchers should have checked out various parameters like sex distribution, other underlying illnesses, mental state (depressed or not etc.), diabetes and other factors to make sure that there is no metabolic bias between the two groups from the start of the study.

2. Deception built into study: we know from other studies that on the long-term diet sodas lead to weight gain by stimulating your appetite for sweets and their subsequent consumption. Often short-term studies show the opposite effect, so it would be false to assume that long-term results would be similar. But most readers who read this quickly would be tempted to think “so it must be OK to continue to consume diet soda drinks!” Off you go to the grocery store and buy another 6 or 12 pack. That’s exactly what the industry-sponsored study set out to do. Somewhere in the back-room of a big soft drink corporation the executives discussed among themselves that their statistics were bad; the sales of diet soft drinks were down; there was too much negative press fuelled by the health food industry. They had to do something about this, so they designed a study where the good guy was the diet soft drink. If the consumer is not buying the results, at least the study helped to confuse people and whenever there is confusion, at least part of the confused population will return to their old habits. After all the study showed “ it is OK”.

Industry Sponsored Diet Soda Study Deceptive

3. Excitotoxins are not OK. Unfortunately all artificial sweeteners are toxic to your brain, they are excitotoxins. MSG is another excitotoxin. The only exception is the natural sweetener stevia, a plant product, which is OK. Splenda is an insecticide, so this is belongs to the xenoestrogens, bad for you as it acts like a foreign estrogen and has cancer-promoting qualities when exposed to it for several decades. The rest of the artificial sweeteners are excitotoxins: they burn your brain cells very slowly and can lead to dementia. Unfortunately they are addicting and your brain will make you feel good when you drink more of it. So, the real reason why the study group on diet sodas did better than the water group is because they did not have to change that habit, there was no withdrawal to deal with and they felt fine. So they could concentrate on dieting and exercising and of course you would lose 13 pounds in 12 weeks doing that. The water group on the other hand had to cope with diet soda withdrawal and on top was challenged by an exercise and weight loss program. As there was no diet restriction, they could compensate a bit for their trouble of withdrawal and eat a few muffins or some extra bread to make up for the lack of their comfort diet drink fix (the satisfaction of consuming the excitotoxin). This slick short-term study design is what should have alarmed the publisher to ask a few hard questions.

4. There needs to be an internal logic in the study: Let’s do a thought experiment where we repeat the study and start with two comparable overweight/obese groups of people and put them on no sugar and no refined carbs for 2 weeks and also on no diet sodas for the same time. After two weeks they are both accustomed to this diet and the no diet soda habit and they have probably lost the same amount of weight from the calorie restriction. Now we start the one group on diet sodas and the other group on water, but strictly controlled for a similar calorie intake in terms of other foods or drinks as much as is humanly possible. I would predict that after 12 weeks the water group will have at least lost the same weight as the diet soda group, if not more. The diet soda group likely will have had some problems with sugar craving and may have had more dietary indiscretions (sneaking in snacks and underreporting them), but this would show up as weight gain.

You may be proud of having completed this well controlled study. The trouble is that your industry sponsor that produces the diet drinks will not like this outcome and would not allow the results to be published. In fact that kind of result would be actively suppressed.

Conclusion:

The diet soda study discussed here is a lesson in biased publishing. We are constantly bombarded by an endless string of meaningless publications that are designed to make the consumer insecure, or bias us for accepting a company’s product in the hope of achieving a certain result (like high sales). Even, if this is not accomplished the company has sold enough of their product just for giving it a try. Beware of the door-to-door sales person. This figure is very much present right in this publication. In this case it is the sales pitch of the diet soda manufacturers! You are looking at a study that was designed to make you buy more of the excitotoxin (aspartame or other artificial sweeteners), which likely contributed to your extra weight or obesity in the first place. It’s up to you to shut the door on this sales pitch. Instead of a diet soda I suggest you make your own drink: squeeze half an organic lemon and top this with mineral water of your choice. Sweeten it with a tiny amount of stevia. This has no calories and does not stimulate you to eat more sugar and starchy foods; but it quenches any thirst and you even get some water-soluble vitamins in the process.

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!

Overuse Of Supplements that Can Create Health Risks

By | Health, Nutrition, Vitamins and supplements

This article is about the overuse of supplements that can create health risks. The Dietary Supplement Health And Education Act of 1994 made it easier for people to acquire supplements and vitamins from health food stores. But since then there has been a proliferation of various products that merchants sell as supplements and not as drugs. It may give you the impression that all supplements are harmless, but this is not so. There are some supplements like vitamin A where you need to watch that you are not inadvertently overdosing, as toxicity is a problem; calcium supplements are also potentially toxic, if overdone. And amino acid supplements (protein supplements) can lead to an overdose of brain hormones. Here is a sample of some of the supplements that I would want you to watch.

1.Vitamin A toxicity

Vitamin A is essential for normal night vision, for red blood cell production in the bone marrow and for the immune system. Here is a brief review about its metabolism. But while small amounts are beneficial for the body, high doses are toxic. In the 19th century the Arctic explorer Elisha Kane reported that consumption of polar bear liver caused severe headaches, drowsiness, irritability and vomiting within a few hours of ingesting it.

The underlying condition is due to “pseudotumor cerebri”. This is a condition that mimics a brain tumor, but coms from an acute overdose of vitamin A contained in liver (Ref. 1).

In the US where people eat enough meat, fish and dairy products, there is no overt vitamin A deficiency. Read this link to avoid overdosing with vitamin A in multiple supplements.

2. Vitamin C

Vitamin C is an important antioxidant vitamin. It plays a role as a cofactor for many metabolic reactions. It is participating in the production of collagen and connective tissues, helps with fatty acid transport and is necessary for the synthesis of neurotransmitters in the brain (Ref.2). The lack of vitamin C has the name scurvy; symptoms include bleeding gums from fragile capillaries, delay in wound healing and impaired bone metabolism. In the earlier research the hope was that vitamin C would prevent colds and cure cancer. More recent re-evaluations found that vitamin C does not prevent you from getting colds. Instead it accelerates the recovery from colds by cutting down the recovery time by as much as 25 to 30%. It also has some cancer protective effects (Ref.2).

1500 mg of vitamin C per day the upper limit

Higher doses seem to be more beneficial, but 1500 mg per day seems to now be the consensus of a reasonable upper dose limit per day. What about kidney stones? Several studies in the past have warned that vitamin C may in some people experience a breakdown into calcium oxalate kidney stones. Here is a brief review of the literature with regard to kidney stone formation. A study regarding the DASH diet, which is used for people with high blood pressure, showed that the incidence of kidney stones is almost half for both men and women compared to controls on a normal North American diet.

Kidney stones from vitamin C a myth

There has been a concern among the medical community that vitamin C as a supplement would increase kidney stones (oxalate stones). However, a 2014 study showed that when both vitamin C and vitamin E are taken as supplements, the kidney stone formation goes down.

Many inhabitants of industrialized countries including the population in the US and other countries are magnesium deficient and this can be a major factor for forming calcium oxalate stones. But it has been known for decades that those who develop kidney stones excrete more oxalates in their urine (so-called “oxalate excreters”). Here is a 1996 study that measured this in detail.

Green smoothies contain a lot of vitamin C

If you are taking in a lot of green smoothies from green leafy vegetables (spinach, kale, Swiss chard) that are high in water-soluble vitamins, you may not require any vitamin C supplements. In other words, think about what else you do and eat and add it up, so you do not exceed a total of 1500 mg to 2000 mg of vitamin C per day.

3. Calcium supplements

Calcium is a key mineral in the body, important not only for healthy bone structure, but also to balance the electrolytes within the blood, in the extra cellular fluid space and within our cells. If calcium is low, the brain is more prone to seizures and the heart can produce dangerously irregular heart beats. We definitely need a balance of calcium! Because calcium is so central to our wellbeing, several factors work together to keep our calcium levels stable: the kidneys, the thyroid, the parathyroid glands, the adrenal glands, the bone as a reservoir of calcium, the gastrointestinal tract for absorption and a good, balanced nutrition. The chapter on “Vitamins and Minerals” of Ref.3 points out that 4000 mg of calcium per day definitely causes toxicity (hypercalcemia and milk-alkali syndrome).

Absorption of calcium

Absorption of calcium depends on the dose you take meaning that only 500mg of calcium carbonate crosses the gut/blood barrier at a time. Vitamin D3 deficiency leads to reduced calcium absorption. But with high doses of vitamin D3, which is now often recommended, more calcium is absorbed, so it is important not to take too many calcium supplements. They can also interfere with iron and zinc absorption and when more than 2600 mg of calcium is taken magnesium absorption is inhibited as well. Calcium can interfere with thyroid hormone supplements (take 4 hours apart) and may reduce the effect of calcium channel blockers, drugs used for angina or high blood pressure.

99% of body calcium stored in bone

There is a balance between calcium stored in bone (99% of total body calcium) and the circulating portion of 1% of calcium in the blood. The parathyroid hormone and calcitonin are also involved in this balance. Hypercalcemia is the condition when calcium is too high. Common causes are the improper use of diuretics (thiazide diuretics), overuse of calcium carbonate supplementation (often for osteoporosis) and overuse of vitamin D3, which increases the absorption of calcium (Ref.3). See your family doctor for blood tests and advice what to do in your case.

4. High protein diets and protein (amino acid) supplements

Many protein supplements are available through health food stores and vitamin stores. The advertisers often state that our food would be substandard and these supplements would help “to regain strength”.  Athletes hope to get stronger muscles from amino acid supplements because they are the building block for protein that builds up muscles. Fact is that no supplements are needed when you eat balanced meals containing meat and fish and you exercise regularly. The protein in your food will be broken down into amino acids and your body metabolizes this into your own protein. Here is a website that reviews the subject of supplementation with amino acids.

Protein supplements or not?

It is clear from this that this is a rather complex problem. Vegetarians may require these supplements to replace protein for the missing meat intake. But the rest of us have to guard ourselves against overdosing with too much meat, amino acids supplements or protein supplements.

High protein diets (Atkins diet and others) have been glorified as being helpful for weight loss. But the long-term effect of such diets lead to chronic kidney damage in those with diabetes and high blood pressure as evidenced by protein leakage in the urine (called ”microalbuminuria”, Ref.4).

Reference range for protein requirement

According to this reference the average protein requirement is 0.6 g of protein/kg body weight/day. This text comments that this would be compatible with the World Health Organization (WHO) recommendation for protein intake. For a person weighing 140 lbs. this translates into about 50 grams of protein per day. Here is a website that explains the upper limit of meat intake with the example of an 8-ounce portion of top sirloin steak.

Protein supplements have become very popular, but you need to be careful when you supplement with this that you do not get an overdose of amino acids. Amino acid profiling has been useful for physicians and naturopaths to examine deficiencies in children or adults checking for essential amino acids in the blood.

Overuse of meat from food and protein supplements

In industrialized countries like the US, Canada and others the larger concern is now the overuse of meat. Atkins-like diets and protein supplements are also a source of extra amino acids. The same amino acid screening tests will find several of the ingredients (amino acids) in these protein supplements to be too high. In this case it is imperative to stop the protein supplements to prevent amino acid toxicity.

This study warns that not enough is known how performance-enhancing supplements affect the metabolism of the body. There are discussions that perhaps upper limits for amino acid supplements need to be established.

5. Creatine supplementation

Creatine supplementation in the sports-minded and in athletes who want to build up muscle mass is of concern. The liver synthesizes creatine from amino acids, which derive from fish and meat. The body breaks this down into the amino acids arginine, glycine and methionine. There is no shortage of these amino acids, but athletes and sports minded people want to push the envelope. They consume additional creatine for their energy metabolism (ATP production) in the muscles to increase their performance (Ref. 5). Creatine is vital for the brain, the heart, the kidneys and the eyes (retina). It is a buffer for lactic acid during anaerobic exercise. Some of the side effects are muscle cramps, diarrhea, fluid retention and kidney failure. Exposure to high heat and dehydration aggravates this. There are no long-term studies of the use of creatine supplements, yet many athletes take them all the time.

Conclusion

We are tempted by various merchants and infomercials to take in more and more vitamins and supplements. This includes protein and amino acid supplements. But when you eat well-balanced meals, preferably organic food, you already have enough nutrients. This includes protein, nutrients, calcium, vitamin C and vitamin A in your food. So you may be inadvertently putting a strain on your kidneys. They have to eliminate whatever it is that is too much for your body to take. Your liver may also be quietly working overtime as well.

Limits of your organs

Your brain gets overactive by the surplus of amino acids that are utilized by the brain to make brain hormones. Your system can only take so much; at one point a surplus of supplements will make you sick! So, be vigilant and think about what your regular food intake already provides. Do you really need that supplement or do you already get enough from your food intake? Are you falling for some marketing scheme? Remember, you are the steward of your own health!

Lead Still Poisoning Us

By | Cancer, Health, High Blood Pressure, Hormones, Infertility, kidney disease, Other neurological conditions, Prevention

We are living in an environment that puts emphasis on quality control, and companies around us take pride in their high quality products, supervised by the FDA. This is how it ideally should be. But is it really? Unfortunately not!

I read the headlines about lipsticks on April 4, 2014 and could not believe it!

When it comes to skin care or cosmetic products, things start to get scary.  Skin is not a barrier, but it is an organ of our body. From skin cream and ointment applications in medicine it is known that pharmaceutical compounds can be applied to the skin, and this way the body can readily absorb active substances.

When it comes to cosmetics, the skin areas to which cosmetics are applied have softer skin, for example the mouth. The vulnerable skin of the lips can readily absorb any chemical substance, and this is where health concerns get even more serious.

In 2010 as the above link shows the FDA determined that all of the “400 lipsticks tested had traces of lead in them, ranging from 0.9 to 3.06 ppm. Another study from California noted that there were other toxic metals in lip sticks and lip glosses containing chromium, cadmium, manganese, aluminum in addition to lead. Even to the unconcerned this sounds like a precarious cocktail of noxious substances! On June 1, 2013 I wrote a blog about toxins in the bathroom. I mentioned the dirty dozen of chemicals that repeatedly are found in cosmetics. With this new information of traces of lead still being in cosmetics, more so than previously reported, women need to be more careful about the choice of lipsticks that they are using.

1.History of lipsticks:

This overview explains that the long-lasting lipstick was only invented around the 1950’s (“Sticks on you, not on him” was the slogan).

Traces of lead were often recorded, but not really thought to be that dangerous. The thinking of the FDA at that time was that children needed to be protected from lead in house paints, but nobody mentioned that lead was part of the red pigment and therefore had to be part of a lipstick. The FDA did know this, but the concentration was supposed to be so small and absorption was thought to be negligible, so considered to be safe for an adult.

Lead Still Poisoning Us

Lead Still Poisoning Us

2. Evidence of considerable absorption of lead:

We know from several studies summarized in this link that various components of cosmetics including lipsticks and lip-glosses get absorbed through the skin. Lead is no exception to this. A 2011 study showed in children in Africa that lead-containing cosmetics for tribal ceremonies in children had higher lead concentrations in their blood than children who did not use these cosmetics.

When doing a PubMed review on the subject I came across a very interesting study: In India there is a practice that parents apply kajal (also called kohl or surma cosmetic) around their eyes, on old traditional practice. Unfortunately this is a lead-containing cosmetic, which is absorbed into the blood and can cause lead poisoning. According to this ancient belief this application of cosmetics around the eyes would keep their eyes cool and clean and is supposed to improve vision, strengthen the eyes and prevent eye diseases. None of these belief are compatible with Western medicine (although a lot of the Ayurveda medicine is valid).

In another 2010 study done in the mountainous Aseer region in the Southwest of Saudi Arabia here there is pristine air quality, 176 pregnant patients with a single baby were followed to see whether there was an effect with regard to lead poisoning in the offspring. Two groups of women were identified, those with lead levels of more than 200 mcg/L in the blood and another group with less than 200 mcg/L. The researchers noted that there was no difference with regard to prematurity, size of the baby or premature rupture of membranes (premature birth).

The conclusion of this study was that there was significant absorption of lead from 100% lead sulfide eye cosmetic “kohl” only on those who used it. To my surprise nobody mentioned anything about the lead levels in the children, which is an example of compartmentalization of science. Common sense would dictate that these children who were at higher risk from mothers with over 200 mcg/L should have received chelation treatments to remove lead (we do this in Western medicine!).

3. Different lip sticks and lip glosses analyzed in Europe and in the US:

A European study showed that 31% of lipsticks and 4% of lip glosses tested positive for lead. All of them had less than 0.88 mg/kg of lead (less than 1 mg/kg). Pink lipstick or lip gloss (0.81 and 0.38mg/kg) tested lower than purple lipstick or lip gloss (0.88 and 0.37mg/kg) and red (0.58 and 0.25mg/kg), but purple tested the highest! I did not know that until now when I researched this.  On average the tests show that the gloss has half the concentration of the lipstick.

Don’t be fooled by the difference in recommended safe levels in Canada (10 mg/kg) and Germany (20 mg/kg). Germany has a very powerful chemical industry with lobbyists that likely lead to this higher “safe” level. In Canada it is the Health Products and Food Branch of Health Canada. No country got it right so far:  A zero tolerance (meaning a blood level of 0 mg/kg in babies and adults alike) is the only solution for humans. A little bit over a long time can lead to chronic chronic lead poisoning.

One other interesting tidbit for those who need to apply something to their lips:

The more expensive lipsticks had much less lead in it than the cheaper varieties (don’t buy the dollar store brands).

Contrast this to an FDA initiated study between 2009 and 2012, published in 2012 that showed that the average lipstick concentration in 400 lipsticks tested  was 1.11 mg/kg, but the highest concentration was 7.19 mg/kg and 13 of them tested 3.06 mg/kg. Here is another review that shows more details (ppm equals mg/kg, so you can compare directly with the figures above. As stated before, in my opinion and that of toxicologists around the world who are the real experts in this a “0 mg/kg” level (no lead in the body) should be the acceptable norm!

Only organic lipsticks and lip-glosses are recommended, if you must wear any of such products. Here is a helpful blog that tells you more positive news (lead and chemical free products).

4. What are the effects of chronic low lead exposure?

Adult lead toxicity is not as common as in the past. Painters in the decades leading up to the 1970’s when laws became more stringent were the ones mostly affected (Ref.1). Keep in mind that more than 30 million tons of lead was released into the air in the US before the lead ban finally remedied this in the 1970’s.  This phasing out was completed in 1995. The mean blood lead levels of Americans declined by 35% since. The EPA is monitoring lead levels in public water systems.

Lead is a nerve poison. It leads to fatigue, insomnia, irritability, lethargy, headaches, difficulty concentrating, memory loss, and tremor. It can also affect the nerves of the extremities, more so in the arms than the legs, which was significant in the past century among painters using lead paints. (“Upper extremity paresis” found in painters). Chronic lead poisoning targets the kidneys and the bone marrow. In the kidneys leakage of the filtration units, called glomeruli, leads to loss of microglobulins that can be measured in the urine among other tests. Above a level of 30 mcg/dL (this is the same as above 300 mcg/L) electrophysiological studies reveal often the ulnar nerve conduction is disturbed, which is the cause for the arm weakness in painters. The bone marrow toxicity can be seen in stippling of red blood cells and anemia develops subsequently. High blood pressure and fertility issues are also common (low sperm count in men, higher rate of spontaneous abortions and stillbirths in women). The gums around the teeth show lead lines (blue discoloration).  I will not get into lead toxicity in children, as this is a big topic of its own. Needless to say symptoms are much worse as any pediatrician can tell you. It goes without saying that should you notice any of these symptoms, see your doctor and have appropriate tests done.

5. Treatment and prevention:

As we do not see acute lead poisoning as much as in the past, except sadly to say still in development countries and highly industrialized areas with lead emissions into the air, I like to emphasize the importance of prevention here.

a)    If you absolutely must have make-up and/or lip sticks or lip gloss, at least go for the expensive, organic products. You owe it to yourself. However, having said that keep in mind that anything you put on your skin anywhere is absorbed to a certain percentage. So, why mess with your body’s metabolism? I really question this. For your skin you can use a product called “Youth serum” from LifeExtension, where only a few drops will suffice to cover your face and neck with a thin film. Within a few seconds this is absorbed into the skin and it will stimulate your skin to grow where wrinkles are, so the wrinkles flatten out in time.

b)    Keep in mind that skin appearance is hormone dependent, males need testosterone as they age and women need bioidentical progesterone. The first link under point 2 above claims that progesterone would be cancer producing. This is not true: it is progestin, a synthetic copy of progesterone that does this. So, bioidentical progesterone in cosmetics would be cancer preventing in women (men should stay away from a woman who has applied this for at least two hours as skin transfer will block testosterone production). Worse still: if a manufacturer uses progestin (the synthetic version), the traces of it over a long period of time will act like xenoestrogens, which can cause breast cancer in the woman who uses such a product and through transfer can cause prostate cancer in a man.

c)    If you insist on using chemicals on your skin, you may want to consider seeing a naturopathic physician who does intravenous chelation. Lab tests are available to assess the levels of heavy metals and toxins in your body. If the levels are creeping up, chelation treatments from time to time may be needed in people with measured elevations of lead levels in blood tests and/or urinary lead level elevations.  Discuss this with your doctor.  Removal of any accumulated mercury, lead, and cadmium or other heavy metals will be an option. I have summarized detoxification methods elsewhere.

Conclusion:

In conclusion, I think that it has to be carefully considered, how much use of lipstick application is necessary. Next the choice of a high quality product is of utmost importance. Taking all the factors together, its constant use cannot be recommended, especially since there is not only lead present, which is a known health hazard. Beside lead there are many other chemicals that get absorbed and their effects have not been adequately tested by the agencies.

Mold Allergies Often Overlooked

By | Allergies, Asthma, Health, Lung Disease, Prevention

In a recent news story extensive mold infestation was found in a house that had oriented strand boards (OSB) instead of plywood walls. The house also was tightly sealed trapping moisture, which contributed to the extensive mold problem.

Mold problems have been around for centuries, but only in the past few decades allergists  have pointed out to their patients how important it is to prevent this from happening.

In the following I will review a few typical scenarios that can lead to mold accumulation.

1. Mold from airtight house construction

The homeowner described in the link above is not the only case in the world that has a mold problem. Energy efficient homes are popular because they save energy costs; homeowners often also respond to gas companies, electric utility companies and government incentives to convert to airtight home construction.

In the 1980’s the construction industry introduced the cheaper OSB products to replace the more expensive plywood for wall construction. This is often the problem with newer house construction. However, older homes are not immune to mold development.

2. Roof leaks in older homes

Older homes that were built in the 1970’s may have plywood walls and have a bit of airflow from poorer wall construction, which would prevent mold formation. But roofs are older and do not always get replaced right away when a leak is detected. It may even take some time in areas where there is less precipitation before it is picked up during a particularly heavy rainstorm. Water that enters from a leaky roof can form a puddle on top of the ceiling where mold softens the drywall material until a leak in the ceiling causes water to drip down onto the floor. The mold spores multiply particularly well in wall-to-wall carpeting, but OSB material is also a good growth opportunity for molds due to the mini air spaces between the glued wood pieces. Plywood with its several tight layers is much more resistant to water penetration and mold growth.

3. Mold growth after hurricanes

After hurricane Sandy images of “black mold” were frequently shown in the media. The problem is that after 48 hours anything that was in contact with water produces mold. However, often with disasters like hurricanes there are evacuation orders and you cannot return to your home for several days. There may be further delay because there is a waiting period for insurers to assess the amount of damage, before you can clean all surfaces affected by mold.

The end is result often that expensive mold sanitation is needed or the person ends up moving away and the house is levelled before a new house can be built.

4. Effects of molds

People with preexisting allergies and asthma are more susceptible to the effects of molds. It leads to itchy eyes, wheezing, coughing, and exacerbation of asthma.

Here is a brief overview what the CDC is stating about mold. This site also explains that you can recognize a mold problem because of a musty smell or foul stench in the air and because of the appearance (discoloration of ceilings or walls, water damage).

You can clean hard surfaces with bleach water. Bleach kills molds, but it may have to be cleaned several times within a few days to get rid of the last spores. Whatever cannot be sanitized in this way must be removed or replaced.

5. Health concerns regarding molds

Ref. 1 reviewed the public concern about the toxic effects of molds. It noted that with the Internet and the popular press having exaggerated some of the connections of symptoms with mold allergies, the term “mold madness” has been coined (Ref.2). Despite the paranoia in the general public about toxins from molds, there is only a small percentage of the population that is sensitive to molds where IgE antibodies and IgG antibodies against molds can be determined through blood tests. These individuals often are also allergic to other environmental allergens like grass pollen and dust mites. The asthmatic reactions in sensitive people are not as severe as what peanut traces would do to peanut sensitive patients, but skin testing and blood test screening for specific IgE and IgG antibodies do often confirm that sensitive people indeed can have specific mold allergies. In the vast majority of people these tests are negative and correlations between mold infestations and allergic reactions could not be verified (Ref.1).

6. Fixing mold damage and dealing with allergies

It follows from this that you should remove any visible molds and fix whatever the cause was for its appearance. Carefully disinfect the areas with diluted bleach water (the CDC recommends 1 cup of bleach per 1 gallon of water) several times. Make sure the areas are dry and not musty otherwise you  have  work on improving ventilation. If you are not one of these hypersensitive persons, there is nothing to worry further. However, if you are hypersensitive an allergist should examine you. Common indoor molds that cause the so-called “immediate type hyper reactivity” are due to the mold species Aspergillum and Penicillium. Most outdoor molds that can cause problems for sensitive people are due to Alternaria and Cladosporium species. The latter would be the ones found in carpets after a leaky roof has caused problems. When the allergist has found specific allergies to one or several of the mold species, allergy shots may be prescribed that would have to be given weekly to the sensitive person who was found to have environmentally induced asthma. Often it takes several years for these desensitization shots to stop the affected person from reacting  to molds. In some cases patients need to stay on these shots life-long.

Conclusion

The key with regard to mold allergies is to prevent mold growth by being vigilant about detecting early problems with leaky roofs, walls and cleaning up water damage right away. When there is a musty tell- tale smell, investigate right away and remedy the problem. For most people this is the end of the story. However, a small percentage of very sensitive people need to consult with an allergist who should investigate whether or not these people would benefit from allergy injections.

In some rare cases the affected person may have to relocate to another house that is free from molds.

Melatonin More Than A Sleeping Aid

By | Anti-aging medicine, Cancer, Health, Hormones, Insomnia, Prevention, Vitamins and supplements

Melatonin has been available to the public in the US since 1992. It is usually used as a sleeping aid or for jet lag related sleeping problems. However, in the last decade much more data about melatonin has come out that has proven that melatonin is a major hormone. The pineal gland contains another brain hormone, serotonin, which is converted into melatonin within that gland. Melatonin is a key hormone that regulates the sleep/wake cycle. It works in concert with cortisol, which has the highest level in the morning while melatonin has its highest level in the evening and during the night. Melatonin also regulates the menstrual cycle and determines when women get into menopause.

Lately new information has come to the forefront showing that there are connections to Alzheimer’s disease, Parkinson’s disease, stroke size and recovery from strokes. Even traumatic brain injury can be minimized when enough melatonin is present. In addition melatonin is an important anti-oxidant.

Finally, there is evidence that melatonin helps to determine how well we age.

In the following I like to review some of the evidence for all of these claims.

1. Melatonin as a hormone

Melatonin levels were found to be very low in breast cancer and prostate cancer patients. It has been determined that the immune cells have melatonin hormone receptors and need melatonin for stimulation. Because of the immune stimulatory effect of melatonin, it is often given as a cancer adjuvant treatment to other cancer treating modalities. Ref. 1 describes that melatonin regulates the female hormones (LH, FSH), which then determine when a woman has her menstrual period and also when she eventually enters menopause. The pineal gland is the master gland for the diurnal hormone rhythms.

Melatonin More Than A Sleeping Aid

2. Melatonin levels decline with age

Melatonin levels in both men and women decline as we age. This figure shows that the highest melatonin levels are reached by the age of 10; by the age of 40 only 15% of the youthful levels remain while by the age of 55 only 5% or less of the original youthful levels are left. This explains why older people are more prone to infections (missing immune stimulation) and why the sleep pattern in older people is changed (shorter periods of sleep, less restful sleep). Ref. 1 points out that with insulin resistance (from diabetes or due to excessive sugar and starch consumption) cortisol levels are chronically elevated, which in turn inhibits melatonin production.

3. Melatonin protects from neurodegenerative diseases

A newer application of melatonin is as a preventative in the neurological field, particularly in the area of Alzheimer’s disease, Parkinson’s disease and the prevention of strokes. With respect to Alzheimer’s disease studies have shown that patients with Alzheimer’s have much lower melatonin blood levels when compared to age matched normal controls. In ischemic stroke patients it was found that stroke patients had much lower melatonin levels when compared to normal age-matched controls. Other studies have shown that pineal gland calcification was associated with low melatonin levels and a high risk for ischemic stroke. This risk was even higher when the patients had high blood pressure, diabetes and high cholesterol/triglycerides. When a stroke has occurred, it is important that the free radicals are removed as quickly as possible, which is where the antioxidant properties of melatonin fit into a rehabilitative program. The presence of melatonin enhances brain plasticity. However instead of using melatonin after a stroke, it is much better to use melatonin regularly before a possible stroke, as this gives a better chance reducing the size of the stroke. This in turn will lead to a faster and more complete recovery after a stroke.

Another important disease of the elderly is Parkinson’s disease. Melatonin helps to prevent oxidative damage to the dopamine producing cells in the basal ganglia thus preventing Parkinson’s disease. As with Alzheimer’s disease, there is a correlation of low melatonin levels and this neurodegenerative disease, which goes beyond the age-related reduction of melatonin levels. In experimental Parkinson’s disease models in mice melatonin was highly effective in preventing deterioration of Parkinson’s disease.

4. Melatonin may extend life

The combination of being a free radical scavenger, an immunostimulant and an integral key hormone allow melatonin to have beneficial effects in the aging process. When melatonin supplements are given, the stimulation of the immune system can cut down infection rates in the elderly, prevent and mitigate degenerative diseases of the brain (Alzheimer’s, Parkinson’s), re-establish sleep/waking rhythms and help reduce arthritis.

Conclusion

Melatonin is a widely used sleep aid. As it is practically absent in people beyond the age of 55, it makes sense to supplement with melatonin in that patient group. However, there are side effects particularly in people on blood thinners as coumadin competes with melatonin in getting eliminated through the cytochrome P450 liver enzyme system. This will result in longer bleeding times in patients on blood thinners who also take melatonin supplements. It is important that patients discuss this with their doctors. However, given all of the benefits described above, for the vast majority of the baby boomers melatonin supplementation would be very beneficial. Doses as a sleep aid vary between 1mg and 5mg at bedtime for most people. Cancer patients require higher doses (10 to 20 mg per day).

Sugar As A Cause Of Cancer

By | Cancer, Diabetes, Health, Nutrition, Obesity, Prevention

It has been known for a long time that cancer cells can survive without the ordinary aerobic pathways of energy production. They can get energy from a metabolic pathway, which bypasses normal cell metabolism (aerobic glycolysis). But many attempts of designing a cancer therapy to exploit this difference have so far been unsuccessful.

This Mayo Clinic website even explains that it would be a myth that cancer would grow better with sugar. The following pieces of research question this myth.

Sugar makes cancer grow faster (activates oncogenes) in fruit flies

In this study from the Icahn School of Medicine at Mount Sinai in New York City fruit flies were used as an animal model. You may ask, why fruit flies; we are not fruit flies, we are humans! As incredible as it sounds, on a cellular level our cell metabolism and the cell metabolism of fruit flies is identical. But the generation time of fruit flies is much shorter and results can be seen in days and weeks. To achieve the same in human trials would take months and years. Also, researchers could breed a strain of fruit flies that was susceptible to develop tumors. When they were fed sugar, the fruit flies developed insulin resistance within a short time. This model was chosen by the researchers as it is known for some time that in humans insulin resistance from diabetes, obesity, and other metabolic diseases leads to a higher risk of developing breast cancer, liver cancer, colon cancer and pancreatic cancer. The researchers wanted to sort out what the metabolic advantage of the cancer cells was under these conditions.

The researchers found that the sugar in the diet activated silent cancer causing genes (called “oncogenes)” in the fruit flies that in turn helped to promote insulin resistance and the development of tumors. Because of the insulin resistance sugar could not enter into the normal body cells, but the tumor was using up all of the sugar allowing the tumor cells to multiply at a rapid rate. The end result was that the sugar from the diet fed the cancer cells directly making them grow faster. Interestingly, when these flies that had developed tumors on a high sugar diet were switched to a high protein/low sugar diet, the tumors stopped growing and were contained.

In this fruit fly example the researchers were subsequently able to block cancer cell growth by special cancer suppressing drugs (acarbose, pyrvinium and an experimental drug AD81), which were given in combination. 90% of the flies given the triple-drug treatment survived to adulthood while control flies not treated with this regimen all died of their tumors.

Although this model was only done in fruit flies and one could question whether or not this was relevant to what is happening in human cancer patients, the following piece of research puts this fear to rest.

Sugar As A Cause Of Cancer

Sugar As A Cause Of Cancer

Human breast cancer cell study in vitro

In January 2014 the American Society for Clinical Investigation published a collaborative study between the Lawrence Berkeley National Laboratory, Berkeley, California, CA and the Hokkaido University Graduate School of Medicine, Japan, which used human breast cells in tissue culture showing that sugar could cause breast cancer.

The original papers of this US/Japanese research team are quite technical and I do not expect you to understand this link where it is published. I posted it for those who want in depth information. The researchers used a simple tissue culture model where they could observe tumor growth in cell cultures under the microscope using a gel where the breast tissue samples were placed side by side with normal breast cells that served as controls. The cell cultures of both normal cells and malignant cells were obtained from the same reduction mammoplasty tissue samples. This way the cell cultures mimicked a situation as close to the reality of what is going on in a woman’s body when breast cancer develops.

The normal breast epithelial cells were seen in culture to get organized as a roundish cell formation (an acinus formation) while the cancer cells were growing as irregular cell clumps. This visual effect was reproducible and is depicted in the paper. With high sugar concentrations in the growth medium breast cancer cells multiplied at a faster rate, not so the normal cells. But some normal cells underwent a transformation into abnormal and cancerous cell types. On the other hand, when sugar concentrations were severely restricted, morphological changes took place where cancer cells slowed down their growth or stagnated while some of them even changed into the normal cell formation (acinus formation). Using various known oncogene stabilizers the investigators could show that the same effect was noted as with the low sugar concentration in the growth medium.

The investigators tested whether other cell lines of breast cancer would show similar results as to the effects of sugar feeding or restriction. They were able to show that high sugar feeding activated cancer cells, no matter where the cancer cell lines originated. The authors discussed that metformin, which is known to control the metabolism in diabetic patients and lowers blood sugar levels, has also been shown to calm down growth of cancer (due to stopping oncogene stimulation), which improves the survival rates of many different cancer types in diabetic patients; it also reduces the risk of developing cancer in those who are taking metformin.

Other investigators have shown in mouse experiments that an impressive lowering of cancer rates could be achieved with low carb diets.

Human evidence for cancer causation and cancer prevention

Several clinical studies seem to indicate that there is a higher cancer rate in diabetics where insulin resistance can lead to activation of cancer producing genes (called oncogenes) and cause various cancers. In this link colorectal cancer and pancreatic cancer are discussed in relationship to diabetes and insulin resistance. High glycemic foods (sugar, starchy foods) were associated with breast cancer, colorectal cancer and endometrial cancer. The majority of trials showed this association although not all. The more obese patients were, the more pronounced the insulin resistance was and the more the relationship to these cancers became apparent. A diet that is high in starchy foods like potatoes, rice and bread is causing pancreatic cancer as was shown by researchers at the Dana-Faber Cancer Institute, Brigham and Women’s Hospital and Harvard School of Public Health. High glycemic diets have shown to cause colorectal cancer, diabetes and being overweight. The Standard North American Diet (SAD) is a pathway to many chronic illnesses due its high load in refined carbohydrates. Ironically the abbreviation for it is “SAD”, which in my opinion reflects adequately its sad influence on health and well being. We know now that sugar and starchy foods lead to insulin overproduction, which in turn causes the metabolic syndrome (also known as “insulin resistance”). This causes the immune system to weaken and fat to be deposited as visceral fat in the stomach area. Visceral fat is metabolically very active as it secretes cytokines like tumor necrosis factor alpha (TNF alpha), COX-2 enzymes and others. Insulin and growth factors from the visceral fat gang up together with the elevated blood sugar, which activates tumor-producing genes (oncogenes) to cause cancer.

While cancer rates are higher in patients with insulin resistance, they were lower in patients who did have normal insulin levels. It is important to concentrate your efforts on normalizing weight, which will normalize insulin sensibility and avoid the development of cancer. Sugar avoidance and avoidance of cereals and starchy foods will help you achieve this goal.

Conclusion

Although the idea that sugar could cause cancer has been around since 1924 (Dr. Warburg), it has taken up to now to be proven in animals and humans.

The purpose of this blog was to show how there is a connection between the consumption of sugar and starchy foods and various cancers in man. Animal experiments are useful in suggesting these connections, but many clinical trials including the Women’s Health Initiative have shown that these findings are also true in humans. It is insulin resistance due to sugar and starch overconsumption that is causing cancer.

We are now in a position to know why people who consume a low carb diet, develop less cancer than people who consume a high carb diet. I have followed such a low carb diet (also known as low-glycemic index food diet) since 2001 and find it easy to follow. However, I do not dispute that it takes some discipline to change the old way of eating to the new one. The benefits are definitely worth it: you are feeling well now and you are staying well as you age.
