Healthier After Age 60

Unhealthy lifestyles have staying power, so what can we do be healthier after age 60? A recent CNN article describes 10 ways how to adopt a healthier lifestyle when you get close to retirement.

The thinking is that 5 years before your retirement at 65 you should perhaps adopt a healthier lifestyle.

2017 study by Dr. King regarding lifestyles before and after retirement

Dr. Dana King was the author of a 2017 study where lifestyles before and after retirement were compared.

Seven factors were examined, namely cardiovascular factors including physical activity, healthy diet, healthy weight, smoking status, total cholesterol, glucose, and blood pressure. Retirees were more likely to have poorly controlled blood pressures compared to non-retirees. 23.9% of retirees had uncontrolled blood pressure versus 15.1% of non-retirees. This difference was statistically significant. There was another significant difference with regard to physical activity. Retirees were 1.85-fold more active than non-retirees. But sadly, the other 5 of the 7 points did not significantly improve. There were no differences in healthy weight, smoking rates, healthy diet, glucose levels or cholesterol control.

Healthier after age 60: how to change your diet

Adopt a Mediterranean diet. This is an anti-inflammatory diet that prevents hardening of the arteries. It lowers the bad LDL cholesterol and also triglycerides. It is also recommended to consume at least 2 tablespoons of olive oil per day. When you cook only with olive oil and use only olive oil and Balsamic vinegar for salads, it is relatively easy to reach or surpass the recommended 2 daily tablespoons of olive oil.

Healthier after age 60: how to change your exercise status

You have more time when you retire. The easiest to get into a routine regarding regular exercise is to get a membership in a gym. In the beginning you may want to see a trainer to show you some routine exercises on weight machines. You start the program off with 30 minutes on the treadmill. Before long you get used to the exercise routine and you feel stronger. But your system also produces much more of the protective HDL cholesterol, which is sensitive to regular exercise. If you have been physically inactive, get some input from your health care provider.

Healthier after age 60: how to change your weight

It is not exercise, but a healthy diet, which controls your weight. Having adopted a Mediterranean diet is a big first step in that direction. But it is also important to cut out sugar and starchy foods (potatoes, rice, bread, muffins, pasta etc.). This will reduce your LDL cholesterol and triglycerides. On the long term you prevent heart attacks and strokes.

Healthier after age 60: how to change your smoking status

It is old knowledge that smoking cuts down on life expectancy. Better quit smoking now than later. It prevents heart attacks, strokes, lung cancer and many other cancers.

Healthier after age 60: how to lower your blood pressure

Regular exercise, weight loss and quitting to smoke will all lower your blood pressure. Some people though continue to have high blood pressure. It is important to seek medical advice regarding this. People with persistent elevated blood pressure need medication to have this controlled in order to avoid getting a hemorrhagic stroke.

Healthier after age 60: how to lower your glucose levels

The diet I described will help you to control your blood sugars. Your doctor can order a hemoglobin A1C, which summarizes your average blood sugars over the past 3 months. Controlling your blood sugar is important to prevent type 2 diabetes. Diabetes reduces your life expectancy significantly. The risks are heart attacks, strokes, blindness, leg amputations, kidney damage and cancers.

Healthier after age 60: how to lower your cholesterol

When I discussed a healthy diet, I indicted that it lowers the LDL cholesterol and triglycerides. This reduces the risk of hardening of the arteries. A regular exercise program increases the protective HDL cholesterol, which reinforces the protection from heart attacks and strokes.

Healthier After Age 60

Healthier After Age 60

Conclusion

Whether we retire or not, we should all strife to achieve these 7 changes of lifestyle that Dr. Dana King has discussed. They were cardiovascular factors including physical activity, healthy diet, healthy weight, smoking status, total cholesterol, glucose, and blood pressure. Each of these factors is important on its own. But when you tackle all of them simultaneously, there is a potentiation of these factors that allows you to get super-healthy. That’s what you want for your life after age 60. It is not too late to start! You want to be healthier after age 60!

Hormones Helping In Menopause

Dr. Filomena Trindade presented a talk about hormones helping in menopause. This talk was part the 26th Anti-Aging Conference of the American Academy of Anti-Aging Medicine in Las Vegas from December 13 to 15, 2018. The exact title of her talk was “Women and cognition: insulin, menopause and Alzheimer’s”. Above the age of 80 Alzheimer’s disease in women becomes much more common compared to men. PET scans of the brain of postmenopausal women in comparison to PET scans of premenopausal women, often show more than 30% slow down of metabolism after menopause. Literature regarding that finding showed that it was mostly the decline in ovarian estrogen production that was responsible for the slow down in brain metabolism. Other factors that lead to Alzheimer’s disease are central adiposity (abdominal) and inflammation in the body.

Brain insulin resistance and Alzheimer’s

Older women with Alzheimer’s have more IGF-1 resistance and IGF-1 dysfunction. Other studies showed that minimal cognitive impairment (MCI) progressing into Alzheimer’s disease (AD) might be due to type-2 diabetes. One of the studies stated the following:

“We conclude that the term type 3 diabetes accurately reflects the fact that AD represents a form of diabetes that selectively involves the brain and has molecular and biochemical features that overlap with both type 1 DM and type 2 DM.“

Another publication said that type 3 DM is a neuroendocrine disorder that represents the progression of type 2 DM to Alzheimer’s disease.

Dr. Trindade presented several hormone studies in postmenopausal women who started to develop Alzheimer’s disease. Older women with existing Alzheimer’s did not respond to estrogen hormone replacement. They did not recover with regard to their memory loss. However, younger women who just entered menopause responded well to estrogen hormone replacement and many recovered from their memory loss.

Hormone changes in menopause

There are a number of hormones that experience changes with the onset of menopause. Estrogen production ceases in the ovaries. The production of progesterone in the ovaries also ends. In addition thyroid and adrenal gland hormone production decreases. Often insulin production is increased, but insulin resistance is present at the same time.

Stress can interfere with progesterone and aldosterone production as pregnenolone is the same precursor molecule for both hormones.

How stress interferes with Selye’s general adaptation syndrome

Stage 1 of Selye’s adaptation syndrome, called arousal, involves elevation of cortisol and DHEA. When stress is over, the patient recovers on his/her own.

Stage 2 is the adaptation stage, where cortisol is chronically elevated, but DHEA is declining. The patient feels stressed, has anxiety attacks and may experience mood swings and depressions.

Stage 3 is the exhaustion stage. The underlying cause of this stage is adrenal insufficiency. Both cortisol and DHEA blood levels are low. Patients often suffer from depression and chronic fatigue.

Other hormones and menopause

DHEA and cortisol (stress) have the same precursor (pregnenolone). This means that when a patient is stressed, DHEA production tends to suffer as most of the pregnenolone is used for the production of cortisol.

Dr. Trindade spent some time explaining the complicated details of thyroid hormones during menopause. In essence stress can interfere with the normal metabolism of thyroid hormones with respect to T3, T4 and reverse T3. The end result is that not enough functioning thyroid hormones are present and hypothyroidism may develop.

Both estrogen and progesterone are lower in menopause. In a longitudinal French study with over 80,000 postmenopausal patients the women that received replacement with bioidentical progesterone and estrogen did the best in terms of low Alzheimer’s rates and lower heart attack rates. You achieve optimal Alzheimer’s prevention best starting hormone replacement at the time when menopause starts. You need both estrogen to control hot flashes and to give you strong bones, and progesterone for preservation of your brain, your hair growth and a good complexion.

Hormones Helping In Menopause

Hormones Helping In Menopause

Conclusion

Hormones are missing in menopause and this becomes the starting point for many postmenopausal complaints of patients. The sooner the physician does blood tests to diagnose hormone deficiencies, the better. Various studies showed that the best result in terms of Alzheimer’s prevention is possible, when estrogen and bioidentical progesterone are replaced right at the beginning of menopause. This approach prevents neuroinflammation. There are no extracellular beta amyloid protein deposits and no intracellular tau protein deposits that typically are present with Alzheimer’s disease. In addition the cardiovascular system stays healthier for longer. It contributes to preventing heart attacks and strokes. A longitudinal French study with over 80,000 women who have received treatment with a combination of estrogen and bioidentical progesterone have excellent survival data. The women also enjoy excellent mental health, no cardiovascular complications and less cancer than controls without hormone treatment.

Death By Fried Chicken

A new study has shown that when you eat one piece of fried chicken per day, you risk “death by fried chicken”.

Details of a postmenopausal women study

This was a study by the same group that published the Women’s Health Initiative. Participants were asked whether they would take part in a dietary prospective study published in the British Medical Journal January 2019.

93,676 women were part of the study, and researchers observed them for an average of 17.9 years. There were 9,320 deaths from cardiovascular disease, 8,358 deaths from cancer, and 13,880 deaths from other causes.

Here are the results for all cause mortality

Total fried food consumption: 1% risk for less than 1 serving per week

3% risk for 2 to 3 servings per week

3% risk for 3 to 6 servings per week

8% risk for eating at least 1 serving per day

Fried chicken consumption:     6% risk for less than 2 servings per month

12% risk for 2 to 3 servings per month

13% risk for at least 1 serving per week

Fried fish/shellfish consumption: 7% risk for at least 1 serving per week

Risk factors for cardiovascular mortality

The following are the risk factors for cardiovascular mortality of the consumer of fried chicken or fish.

8% risk for less than 2 servings per month

17% risk for 2 to 3 servings per month

12% risk for at least 1 serving per week

Fried fish/shell fish consumption.: 13% risk for at least 1 serving per week

Cancer mortality from fried foods was not that clear. Here are two interesting statistics.

Cancer mortality for fried fish consumption

-8% risk for less than 3 servings per month.

Other fried food consumption:

+9% risk for less than 2 servings per month.

Discussion of the results

This has been an extensive prospective study involving a large amount of postmenopausal women from the Women’s Health Initiative. In addition the observation time was very long, namely an average of 17.9 years. These properties give the study an unusually strong statistical significance. The following features are noteworthy.

Comparing fried chicken with fried fish/shell fish

Fried chicken, prepared in the US in 40 different states has a risk of 17% to cause a heart attack or a stroke for persons that consume two or three servings per month.

Fried fish/shell fish only has a risk of 13% when eaten once per week of causing a heart attack or stroke.

Comparison between this study and a Spanish study

The authors discussed that their findings are different from a Spanish study that found no increased cardiovascular risk of deep fried chicken. They pointed out that in Spain the oil used for deep-frying is usually olive oil while in the US it is mostly corn oil. Frying causes the process of oxidation and hydrogenation, which leads to a loss of unsaturated fatty acids. Linoleic acid experiences a reduction and a corresponding trans fatty acid formation. The end result is that the concentration of trans linoleic acid increases. This may be an important factor increasing the risk of heart attacks and strokes in the US where the use of corn oil is common for deep-frying, but not in Spain where chefs use olive oil instead. Olive oil is a monounsaturated fatty acid and stable with cooking.

Comparison between fried fish consumption and other fried food

There was a less than average cancer risk (-8%) when fried fish consumption was compared to other fried food consumption. With other fried food consumption a +9% risk for cancer mortality was found. This is a spread of 17%. Frying fish, which contains omega-3 fatty acids may neutralize the cancer causing effect from frying other foods. Omega-3 fatty acids are natural anti-oxidants. This may be the reason why fried fish/shell fish did not cause excessive cancer deaths.

Other considerations

The authors did not delve into the quality of the chicken meat in the US fast food industry. It is known that chicken farmers use an arsenic compound (“3-nitro”) for faster growth and prevention of infections among crowded living conditions of the birds.  3-nitro is a carcinogen, which contributes to cancer toxicity in humans as non-organic chicken meat contains it.

It likely would be wiser to buy organic chicken and pan-fry it in olive oil. Alternatively you may want to BBQ chicken at a low temperature.

Death By Fried Chicken

Death By Fried Chicken

Conclusion

Buying deep fried chicken from a fast food outlet is a favorite for many Americans. This study shows clearly that it is deep fried chicken that causes the highest heart attack and stroke mortalities in the US. But “death by fried chicken” does not have to be. The problem may be that the kitchen used the wrong fats to prepare deep fried chicken. In a similar study in Spain there was no increase in cardiovascular risk when cooks used olive oil for deep-frying chicken.

Alternative to buying fast food

The small extra step of buying organic chicken and preparing it at home in a frying pen with olive oil will pay big health dividends. Similarly, fish and shellfish prepared in olive oil at home will also not have any risks for you. A lot of people rave about the convenience of buying deep fried food and in this case deep fried chicken. This article, however, shows that it is time that we take at least some control back in our own hands to prepare healthy food for our families and ourselves. It is a poor trade to choose convenience over health!

Health Benefits of Vitamin E Tocotrienols

Dr. Barrie Tan gave a talk about health benefits of vitamin E tocotrienols that I attended. This occurred at the 26th Anti-Aging Conference of the American Academy of Anti-Aging Medicine in Las Vegas (Dec. 13-15, 2018).

First of all, Dr. Tan stressed that there has been some confusion about vitamin E, as in the past the school of thought was that the main active ingredient of vitamin E would be alpha-tocopherol. Furthermore, many clinical trials with this ingredient go back to the 1960’s, which showed antioxidant activity. But further research revealed that there were many other tocopherols and isomers of tocotrienols. What is worse is that beneficial cardiovascular effects of the newer tocotrienols became null and void through traces of alpha-tocopherol in the mix.

Finally, this led to purer vitamin E production without alpha-tocopherol contamination. Recent clinical trials found that health benefits of vitamin E tocotrienols are linked to delta- and gamma-tocotrienols. They were many times more active in preventing heart attacks and strokes than former mixes of vitamin E.

Annatto derived tocotrienol

In 2002 scientists were able to extract pure tocotrienol without contamination of alpha-tocopherol from annatto. Prior to this vitamin E came from rice and the red palm fruit. But rice contained 50% of tocopherols, while the red palm fruit contained 25% of it.

Here are several sources of vitamin E. The components of tocopherols and tocotrienols vary depending on the source as follows.

Rice: 50% tocopherols (inactive or antagonistic), 15% alpha- and beta-tocotrienols (less active); 35% delta- and gamma-tocotrienols (most active).

Red palm fruit oil: 25% tocopherols, 25% alpha- and beta-tocotrienols, 50% delta- and gamma-tocotrienols.

Annatto: 90% delta tocotrienols and 10% gamma-tocotrienols.

Subsequent research was able to discern between the detrimental effect of alpha-tocopherol and the protecting effect of delta- and gamma-tocotrienols. Now the recommendation of Dr. Tan is to use only annatto-derived vitamin E to prevent heart attacks and strokes. He called annatto-derived vitamin E the vitamin E for the 21st century.

Tocopherol interfering with action of tocotrienols

Dr. Tan explained that alpha-tocopherol blocks absorption of tocotrienols from the gut. It also prevents storage of tocotrienols in liver and fatty tissue. By itself alpha-tocopherol leads to premature elimination of prescription drugs. It also increases blood pressure and cholesterol. What is worse is that alpha-tocopherol increases the risk of prostate cancer and glioblastoma in humans. It also decreases bone mass and increases LDL oxidation, which leads to accelerated hardening of the arteries.

Action of tocotrienols

In contrast to tocopherols, tocotrienols (particularly the delta and gamma isomers) have all the attributes that you want from vitamin E. It has the highest anti-oxidant properties among the tocotrienols. Delta- and gamma-tocotrienols accumulate in LDL cholesterol and in lipid-rich organs like the brain, heart, kidneys, lungs, spleen and skin. Abdominal adipose tissue from obesity also stores delta- and gamma-tocotrienols.

Tocotrienol’s antioxidant activity

When you use a vitamin E preparation consisting of only delta- and gamma-tocotrienols, the portion of vitamin E contained in cell membranes protects against oxidation. Vitamin E  also protects lipids from omega-3 supplements and lipids in foods and beverages from oxidation. Tocotrienols are about 50-fold more potent as antioxidants compared to tocopherols. Based on this information it is not by chance that the following statistics were the results of clinical trials.

Cholesterol lowering effect of vitamin E delta- and gamma-tocotrienols

Dr. Tan cited a 6-week placebo controlled clinical study where the anti-oxidant power was measured in terms of reduction of LDL and total cholesterol.

A group of elderly patients were divided into a subgroup that had normal levels of cholesterol and another subgroup with elevated lipid levels. After 6 weeks of taking a vitamin E preparation consisting of 90% delta tocotrienols and 10% gamma-tocotrienols the blood levels dropped as follows.

Hypercholesterolemic group:    LDL cholesterol    Triglycerides       CRP

                                                          20-28%                11-18%         31-48%

In healthy elderly patients the CRP still dropped 21-29%. Gamma-glutamyl transferase, a predictor for heart attacks dropped by 14-20%.

Another study on postmenopausal women for 12 weeks also showed beneficial effects of tocotrienols.

Hardening of arteries

Dr. Tan explained that hardening of arteries is due to a combination of factors. It is due to combined chronic inflammation and deposits of LDL cholesterol in the wall of the arteries. Studies have shown that monocyte adherence is the first step in fatty streak formation in arteries. Delta-tocotrienol is 60 times more powerful than alpha-tocopherol in inhibiting monocyte adherence. Gamma-tocotrienol is 30 times more powerful than alpha-tocopherol. This proves that taking a vitamin E preparation of 90% delta tocotrienols and 10% gamma-tocotrienols is the most advantageous vitamin E combination to take.

Health benefits of vitamin E tocotrienols include hardening of carotid artery

A 4-year study examined the effect of taking 240mg of tocotrienol-tocopherol supplementation. 88% of patients who took the vitamin E supplement showed improvement (regression of the carotid artery stenosis). Placebo patients deteriorated 60%, only 8% improved. In the 4th year of the study total cholesterol decreased by 14% and LDL cholesterol fell by 21%.

Health benefits of vitamin E tocotrienols include type 2 diabetes

Patients with type 2 diabetes received tocotrienols. Within 60 days of taking 250 mg of tocotrienols the serum total lipids were reduced by 23% and total cholesterol by 30%. The LDL cholesterol was reduced by 42%. Triglycerides were also lowered by 15-20%. C-reactive protein (CRP), a marker for inflammation was lowered between 35-60%.

Beneficial effects of tocotrienols on the eyes and skin

Tocotrienols have antioxidant effects on the eyes and skin. With regard to eye diseases glaucoma and cataracts are improving and macular degeneration in diabetics is responding as well.

The subcutaneous fatty tissue absorb tocotrienols well. Delta- and gamma-tocotrienol largely neutralize oxidative stress from UV light and ozone.

Non-alcoholic fatty liver disease (NAFLD)

This condition has a close association with obesity and the metabolic syndrome. The liver stores excessive fats. About 30-40% of US adults suffer from this disease. Researchers conducted a 12-week study with 71 NAFLD patients. It was randomized, double blind and placebo-controlled. After 12 weeks of supplementation with delta- and gamma-tocotrienol there was evidence of reduction of stress on the liver by improved liver enzymes. The ALT and AST enzymes were reduced by 15-16%. There was also an 11% reduction of triglycerides and 18% lowering of CRP, which indicates a reduction of inflammation. The fatty liver index score showed a decrease of 11%. This suggests that there was intrahepatic fat reduction. The group with delta- and gamma-tocotrienol supplements lost on average 9.7 pounds. Here is another study regarding non-alcoholic fatty liver disease and using tocotrienols.

Health Benefits of Vitamin E Tocotrienols

Health Benefits of Vitamin E Tocotrienols

Conclusion

Vitamin E supplementation is undergoing rejuvenation after research has established that it is delta- and gamma-tocotrienol that are the active antioxidants among the 10 or so tocopherol and tocotrienol isomers. The most active of them, delta- and gamma-tocotrienol, have excellent absorption in the gut and migrate through the blood stream to the lipid rich cells in the body. Key organs like the brain, heart, kidneys, lungs, spleen and skin accumulate vitamin E. Even the abdominal adipose tissue takes up vitamin E, which is beneficial when a person becomes obese or develops diabetes. Apart from lowering triglycerides, total and LDL cholesterol, vitamin E (delta- and gamma-tocotrienol) is also important for directly interfering with hardening of the arteries.

Vitamin E protecting skin, eyes and liver

Vitamin E also protects the skin and eyes against UV light. There can be a partial reversal of tissue damages. Finally, I pointed out that vitamin E can reverse non-alcoholic fatty liver disease (NAFLD). It is important to leave out alpha-tocopherol, which is an older form of vitamin E that is cheaper to produce, but will interfere with the function of delta- and gamma-tocotrienol as explained. As I mentioned earlier, various vitamin E supplements are on the market. It is obvious that they are not equally beneficial.

I recommend you take about 125 mg of vitamin E in the form of delta- and gamma-tocotrienol every day. I take Annatto tocotrienols (Cardiovascular Research Ltd.) 1 softgel daily.

Biological Age Is Different From The Chronological Age

Biological age is different from the chronological age said professor Morgan Levine from Yale Medical School. She is working in the department of pathology. She has found in her research that people of the same chronological age have very different biological ages. From a biological standpoint they may be much younger or older than their chronological age. When people are younger than their chronological age, they have less disease and less mortality. This article has reviewed the facts.

Measuring biological age

Dr. Levine also has developed tools how to determine the biological age. And when the biological age is higher than the chronological age, she recommends lifestyle changes that will set back the biological clock. We age differently according to what we eat, how our genetic make-up is, which we cannot change, whether we are physically active and what environmental toxins we are exposed to. So, the biological age determines our health status and what our final life expectancy will be.

Biomarkers for biological age

A simple blood test that your family doctor can order consists of the following. A fasting blood sugar, kidney and liver tests, immune tests and inflammatory tests. In addition the doctor will want to know whether you are smoking or not, how much alcohol you consume and how much red meat and processed meat you eat. A computer program processes these results, which determines your biological age.

Lifestyle improvements can lower biological age

Biological age testing has a strength built in. By changing your lifestyle you can lower it. When you exercise more regularly and switch to eating a Mediterranean diet you can lower your biological age. Other studies have shown that the Mediterranean diet is anti-inflammatory. A telomere test, which also determines the biological age, is fixed. It is not easily changed by dietary measures and increasing your exercise.

Dr. Levine said: “I think the most exciting thing about this research is that these things aren’t set in stone.”

Putting the biological age to the test

Dr. Levine was curious what her own biological age was. She entered her blood test data and lifestyle facts into the computer. She was surprised that her biological age was not as good as her first assumption. Now she is trying to get more sleep, has increased her exercise level and improved her diet.

Her research team is working on getting the algorithm online so that everyone will be able to put one’s blood tests and other data into the computer program and calculate the biological age. The program will also recommend what steps are likely most helpful to increase one’s health and decrease the biological age.

Lower your biological age

No one wants to live a long life, if they are in pain and have various illnesses like arthritis or Alzheimer’s. But things are different, if they can change lifestyle factors and maintain a low biological age for a long time. Now they can stay active, have no pains and are able to contribute to society.

“By delaying the onset of diseases and cognitive and physical functioning problems people can still be engaged in society,” Dr. Levine said. “I think that is the ideal we should be striving for.”

Other literature about biological age

Inflammation increases the biological age

In this publication the authors stressed that inflammation is the common denominator for developing disease and premature aging. The authors stress further that it is mandatory to change one’s lifestyle to lower the biological age and live longer.

Diastolic blood pressure predicts mortality

In an older study the diastolic blood pressure was related to mortality. The higher the diastolic blood pressure was, the higher the mortality.  The authors also noted that it was the persons with the higher biological age who were at the highest risk of dying.

Scientific study about the predictors for the biological age

Here is a scientific study that examines predictors for the biological age.  This is not easy reading, but I placed it here for completeness sake.

Link to a site that can calculate your biological age

Here is a link to a site that calculates your biological age. It is probably not as good as Dr. Levine’s computer analysis will be when it is available. However, it is a good approximation to what it will be like.

Biological Age Is Different From The Chronological Age

Biological Age Is Different From The Chronological Age

Conclusion

The dream of staying younger for longer is not new. Research has shown that we actually can do something about it. If we look after our lifestyle, don’t smoke, don’t drink excessively, eat a sensible Mediterranean-type diet and exercise regularly, our biological age will be less than our chronological age. It is the biological age that determines how old we get and whether or not we will suffer from age-related illnesses. Researchers also found out that when your biological age is younger than your actual age mortality will occur later. The math is simple. Let’s assume that your biological age is 15 to 20 years younger than your chronological age. As the average life expectancy presently is 80 years, your life expectancy can increase to 95 or 100 years.

Not Exercising Is More Risky For You Than Smoking

A new study showed that not exercising is more risky for you than smoking. We all know that smoking puts you at risk to get a heart attack or a stroke. It can also cause lung cancer and other cancers. So, hearing that not exercising is even more risky than smoking comes as a shocker.

The study

Dr. Wael Jaber, a cardiologist at the Cleveland Clinic was the senior cardiologist of this study. It was based on 122,007 patients who underwent tests using an exercise treadmill test at the Cleveland Clinic. This took place between the beginning of January 1991 and the end of December 2014. The end point in the study was all-cause mortality. The question in the study was whether exercise and fitness were lowering the risk of mortality. The result showed that 12% of the study group had the lowest exercise rate. This sedentary group had a mortality rate that was 500% higher than the top exercise performers. Compared to someone who exercises regularly the sedate group that hardly exercises still had a 390% higher death rate.

No ceiling of the benefit of exercise

What was astounding to the researchers was the fact that there was no ceiling of the benefit of exercise. The ultra fit group still had a super low mortality rate, lower than the next higher fitness group. Age did not matter either. Whether you were 40 or 80, the more you exercised, the lower your mortality rate was.

Comments about the study

Jaber said: “Being unfit on a treadmill or in an exercise stress test has a worse prognosis than being hypertensive, being diabetic or being a current smoker. We’ve never seen something as pronounced as this and as objective as this.” He went on to say: “If you compare the risk of sitting versus the highest performing on the exercise test, the risk is about three times higher than smoking.”

A sports medicine physician, Dr.Jordan Metzl who was not part of the study, said: “Cardiovascular disease and diabetes are the most expensive diseases in the United States. We spend more than $200 billion per year treating these diseases and their complications. Rather than pay huge sums for disease treatment, we should be encouraging our patients and communities to be active and exercise daily.”

Other studies showing that not exercising is associated with a high mortality rate

 

The STABILITY trial

This trial was based on 15,486 patients with heart disease and found that even 10 minutes of exercise per day reduced mortality. They compared the death rate of people engaging in 10 minutes of a brisk walk with a group who did not exercise at all. The brisk walkers had a 33% lower death rate than the group who was entirely sedentary.

A lack of exercise causes a lot of chronic diseases

This review article mentions that a number of chronic diseases were related to sedentary lifestyle. Major diseases like heart attacks, strokes, arthritis, depression and anxiety and others were clearly much more common in people who were more sedentary than those who were exercising regularly.

Poor lifestyle in general causes diseases

Lifestyle, in particular regular exercises, a healthy diet and NOT smoking has a profound positive effect on our health. In one study researchers showed that 79% of major diseases including heart attacks and strokes could be prevented with a healthy lifestyle. I reviewed this in this blog.

High blood pressure reduced by regular exercise

This 2017 study from Brazil has examined the effects of regular exercise on high blood pressure patients. They came to the conclusion that regular exercise can be as powerful as blood pressure lowering medication. Both bring down systolic and diastolic blood pressure. Even complications of previously untreated high blood pressure will be reversed with regular exercise while medication will not have this positive effect. Controlling high blood pressure with regular exercise will prevent diseases like heart attacks and strokes and the associated mortality.

Regular exercise and diet change to prevent type 2 diabetes

In this 2015 study the researchers noted that a combination of adopting a healthy diet and regular exercise could lead to weight loss. This was shown to prevent type 2 diabetes. The authors questions why such a lifestyle change was not more widely taught to people to prevent cardiovascular diseases and diabetes.

Not Exercising Is More Risky For You Than Smoking

Not Exercising Is More Risky For You Than Smoking

Conclusion

The medical profession knows for a long time that regular exercise is good for your health. But there always was a concern that perhaps too much exercise may be hazardous. A 2018 study from the Cleveland Clinic followed 122,007 patients for 14 years. All patients underwent an exercise treadmill test as a baseline. The end point was mortality during the 14 years of follow-up. The results made clear that there was no upper limit of exercise. Patients who were exercising the most still had a lower mortality than those who exercised less.

Sessile patients

But perhaps the most impressive result was that sessile patients who did hardly any or no exercise had the highest mortality. Their mortality was higher than that of smokers who exercised a little bit. If you want to avoid getting a heart attack, a stroke, diabetes or many types of cancer, exercise regularly, don’t smoke and eat a Mediterranean type diet. Regular exercise can reduce cardiovascular disease by 79%. And since the Cleveland study we know that more exercise is even better as the top athletes had the lowest mortality.

Distribution Of Obesity In Women And Men Is Different

The distribution of obesity in women and men is different, when they gain weight on a low fat/high carb diet. The distribution of fat follows a pear shape in women due to fat accumulated around the hips. In males excessive fat accumulates around the waist, which gives them an apple shape appearance.

Researchers at the University of California, Riverside (UCR) have done experiments using a mouse model. They wanted to see what changes take place when obesity develops. Djurdjica Coss was the lead researcher of the study from the UCR School of Medicine.

The reason why this study was thought to be necessary

Many men and women have relatively normal weights until their mid 50’s. But when women approach menopause, they tend to accumulate fat in the thigh areas (pear-shape obesity). When their weight continues to rise, they also accumulate weight in the abdominal area. It is general knowledge that the fat in the abdominal region is metabolically more active producing inflammatory kinins.

Men above the age of 50 or 60 are also accumulating fat, but typically in the abdominal area right away. The name for this is apple-shape obesity. Unfortunately this is the fat we just discussed, metabolically active with inflammatory kinins. It is known to be the cause for heart attacks and strokes as it accelerates hardening of the arteries in the whole body. Dr. Coss found in doing experiments on mice that estrogen plays a major role in the development of obesity as discussed below.

The mouse experiments to study the development of obesity

The research team of Dr. Coss compared a group of mice that had their ovaries taken out. The ovaries in females are the main source of estrogens. They fed them a high-fat diet comparing their weight gain to that of male controls on the same diet. Obesity leads to a change in metabolism, called metabolic syndrome. This condition has an association with the production of inflammatory substances originating from the abdominal fat accumulation. Both male and female mice underwent a series of blood tests. They were also physically inspected. The female mice had the pear-type accumulation of fat, the males an apple-type fat accumulation.

More details about what obesity did to the experimental mice

In males there was a reduction of sperm count in the obese group as well as low muscle strength. In addition they were low in energy, had a lack of libido and their testosterone levels were low. The sperm number and the testosterone level had fallen to 50% of what they were when their weight was normal. This is what happens in human obese males as well. The inflammatory substances, that the abdominal fat creates, broke down the blood/brain barrier, and this affected the brain.

Among the female mice there was no neuroinflammation in the brain. There was no change in their hormones, which was quite a remarkable finding. This was a surprise and points out that beside estrogens there are other mechanisms to protect females from the effects of obesity.

Brain inflammation from obesity

Dr. Cross explained that in male mice the fat accumulation was of the apple-type. Female mice had the pear type fat accumulation. The fatty tissue in females did not release inflammatory kinins. On the other hand, the abdominal fat in the males released inflammatory kinins. These attracted macrophages, which is a cell type of the immune system. Activated macrophages now became aggressive and broke down the blood/brain barrier. This resulted in neuroinflammation of the brain. The brain normally is an immune protected site because of the blood/brain barrier. When this breaks down because of the action of inflammatory kinins from abdominal fat, the brain starts to develop memory loss like in Alzheimer’s disease.

Women before and after menopause

In females who still produce enough estrogen, fat from the pear type obesity distribution does not produce inflammatory kinins. This explains the relative protection of premenstrual women from heart attacks and neuroinflammation. But menopausal women start accumulating fat around the abdomen as well. At that point they can also develop inflammatory kinins and neuroinflammation. This is why the heart attack and stroke rate increases in postmenopausal women with apple-shape obesity.

Other studies supporting the effects of obesity in men and women 

Inflammatory substances in obese people affecting their brain

This publication shows that in a group of 141 neurologically healthy obese individuals the anti-inflammatory defense in the brain was weakened. Subsequently, various brain conditions developed because of the inflammatory substances affecting the brain.

How obesity affects your body functions

Obesity affects the body in various ways. It is particularly the apple type obesity that causes inflammatory substances circulating in the blood. A multitude of conditions can develop from this.

  • The cholesterol shows an increase of the bad LDL cholesterol and a reduction of the good HDL cholesterol.
  • The blood pressure rises. Without treatment high blood pressure can cause strokes.
  • Type-2 diabetes often develops because the insulin production cannot keep up with the demand. A second factor is a loss of insulin receptor sensitivity. As a result the insulin receptors of the body cells become resistant to insulin.
  • The gallbladder often develops stones, which may require gallbladder surgery.
  • Some cancers are increasing in frequency: endometrial cancer, breast, colon, kidney, gallbladder, and liver cancer.
  • Anxiety, depression and other mental disorders are more common, in part because of the neuro-inflammatory processes that I mentioned before.
  • Body pain and problems with physical functioning: obese people have more back pains, hip and knee pains from the extra weight. Slim people are less likely to have these problems. Obese people require more hip and knee replacement surgeries for end-stage arthritis than slim people.

Difference of metabolism in pear-shape versus apple-shape obesity

Back to the pear versus apple distribution of fatty tissue in obesity. diabetes, heart disease, high blood pressure and strokes as the apple type obesity. The difference in metabolism between the two is explained in detail here.

Distribution Of Obesity In Women And Men Is Different

Distribution Of Obesity In Women And Men Is Different

Conclusion

You may have heard that women tend to accumulate fat more around their hips, possibly because of hormonal factors. This is a pear-type fat distribution. In men who turn obese the fat accumulation follows an apple pattern. This type has a more aggressive metabolism in the fat tissue with inflammatory kinins accessing the blood circulation. It also affects the blood/brain barrier. Normally this barrier does not allow proteins to enter the brain. But when a person is obese, inflammatory kinins and proteins can enter the brain freely causing mental illnesses like depression and anxiety. Many obese people also develop type-2 diabetes leading to heart attacks and strokes.

Low fat diet from the 1980’s

The low fat diet of the 1980’s has caused a lot of obesity around the world. The problem is that merchants who provide low fat products have replaced fat with refined sugar. The liver converts refined sugar into fatty acids and triglycerides. These end up as fatty tissue. Given enough time this is causing obesity. Those who are obese need to cut out refined sugar in its many disguises. In addition they also need to cut down their starchy food intake. In the gut starchy foods break down into sugar.

When you cut out sugar and starchy foods, a person will typically lose 50 pounds in 3 months, at which point they have lost the label of “obesity”. They will also feel more energetic. The best advise for you is to maintain your weight loss with a Mediterranean diet. Research studies have shown that it is beneficial and anti-inflammatory.

No Amount Of Alcohol Is Good

New research, more extensive than previous research has shown that no amount of alcohol is good.

This is completely against the widespread belief that moderate consumption of alcohol would prevent heart disease.

Specifically, previous research had shown the following: one glass of alcohol per day for women and 2 glasses of alcohol for men was reportedly make us live longer.

New research with larger population numbers

But a new study involving much larger population groups, all ages, and drinkers versus non-drinkers came to a different conclusion. It concluded that the previous recommendation was based on only heart attack rates, but excluded other causes of sudden death like heart failure, a rupture of the aorta (aneurysm), high blood pressure that kills (fatal hypertensive disease) and strokes. With the compilation of all these cardiovascular diseases, the statistics suddenly started to look different. Now even small amounts of alcohol killed. What is worse, there was clear evidence that binge drinkers have much worse survival statistics than moderate drinkers. When you drink according to the American Heart Association’s recommendation, you drink smaller amounts of alcohol daily.

Binge drinking

But many of us like to live it up on weekends or whenever there are friends over who also like a few drinks. This binge drinking habit lowers the life expectancy by an average of 10 years. It does so because the list of complications I mentioned above. In addition there are alcoholic liver cirrhosis, pancreatitis and various cancers that shorten your life.

Global health study

The funders of this global health study was the Bill and Melinda Gates Foundation, and it looked at the burden that alcohol puts on 195 countries. The original study appeared in the Lancet. The combined study population was 28 million individuals. There were 649,000 cases of various deaths due to alcohol. Here is a summary of the abbreviated outcome of the global health study. As you can see from this, there is no safe level of alcohol consumption as even small amounts of alcohol over a long period of time lead to significant damage in the body. You can prevent heart attacks to a certain extent. But instead people die from a ruptured aorta, from strokes or from heart failure. The leading cause of death for men and women age 15 to 49 worldwide was alcohol. It accounted for almost 1 in 10 deaths.

Some alcohol-related statistics

The following were the observaions in the study.

  • Over 300 disabilities and diseases were directly related to alcohol consumption. The findings were collected in 195 countries, classified by age and sex. The data was gathered between 1990 and 2016.
  • Globally, 2.4 billion people drink alcohol. 25% are women who consume 0.73 drinks on average each day, 39% are men drinking 1.7 drinks a day.
  • Denmark, Norway and Germany drank the most alcohol globally.
  • For ages 50 and up the leading causes of death were: road injuries, suicides and tuberculosis.

More statistics

  • Most deaths caused by alcohol came from cardiovascular disease and cancer for all countries.
  • When you look only at drinkers, the standard recommendation of the American Heart Association regarding low alcohol consumption seems true. But the new study compared non-drinkers with drinkers. From this it is clear that even one drink a day has a risk of premature death.
  • At the age of 40 cutting down long-term alcohol use will add 1 to 2 years of life expectancy.
  • For all ages 2.8 million people die globally every year from alcohol related diseases.
  • Half of the world does not drink at all. This means that the ones, who drink, consume double as much as the statistics show.
  • Americans prefer beer. They drink about 27 gallons of beer, 2.6 gallons of wine and 2.2 gallons of spirits per adult/year.

Common clinical conditions from alcohol consumption

Binge drinking is the consumption of 5 drinks or more in an evening for men or 4 drinks for women. The CDC is concerned about binge drinking, because of its association with significant organ damages. There are 4 major concerns regarding these effects. Heart disease and cancer; diabetes; memory loss and appearance. In the following I will zero in on these alcohol-related conditions. 

Heart disease

As this article pointed out above, there is a very limited protective effect, but mostly in above 55-year-old women who drink in moderation (1 glass of alcohol; per day). They have some protection from developing heart attacks, because their LDL cholesterol gets lowered and their clotting system is influenced in positive ways. But 6% of breast cancer in women is due to the effect of alcohol consumption, which is a downfall. For both men and women binge drinking is what kills. Binge drinkers who drink more than 100 grams of alcohol per week (more than 7 drinks in the US) experience increased deaths. The causes are heart failure, strokes, fatal hypertensive disease and fatal aortic aneurysm, where the main artery bursts. Apart from that alcohol-related pancreatitis and liver cirrhosis can kill as well.

Cancer

A relatively new finding is that alcohol has a close relationship to causing various cancers. Alcohol weakens the immune system. Also, alcohol has a negative influence on the bacterial composition, the microbiome in our digestive tract, is. This can be a cause for colon cancer. Liver cancer, mouth cancer and breast cancer also has a direct relationship to increased alcohol consumption. Esophageal cancer and laryngeal cancer are also related to alcohol consumption.

Diabetes

Alcohol can stimulate the pancreas to release insulin, which may give you hypoglycemic attacks. As alcohol contains empty calories, over the course of several years alcohol consumption can add to your weight, causing obesity and type 2 diabetes. As diabetes has detrimental effects on the heart and blood vessels, this mixed with alcohol consumption, can worsen cardiovascular disease thus increasing the risk for heart attacks and strokes.

Memory loss

In the beginning of chronic alcohol consumption you may enjoy the relaxing effect of alcohol. This is merely the toxic effect of alcohol on brain cells. Alcohol has the effect of inhibiting brain cells, which makes you feel relaxed, super-sociable and even silly. In reality you are starting to loose control. After several years of this effect you are left with feelings of anxiety, depression and anger. This is when trouble starts to occur. People out of control are more likely to get into fights and get injured or killed. People can develop blackouts where they do not remember parts of the evening or an entire event. Memory loss is starting. The hippocampus is an important part of the brain that is involved in processing short- term memory into long-term memory. A form of dementia can occur that was brought on by chronic alcohol overconsumption.

Appearance

Alcohol dries out the skin cells and body cells. The face gets wrinkles. Your skin looks parched and gives you the appearance of a prematurely aged person. Alcohol can interfere with your sleep and when you have a lack of it you end up with dark circles around your eyes as well as puffy eyes. It does not make for a good picture, whether it happens inside the body or on your skin!

No Amount Of Alcohol Is Good

No Amount Of Alcohol Is Good

Conclusion

A new study that was larger and more comprehensive than any previous study has exposed the myth that one drink for women and two drinks for men would protect you from heart disease. It may protect you from heart attacks, but it definitely does nothing to protect you from other heart conditions. There is also sudden death from heart failure, a rupture of the aorta (aneurysm), high blood pressure that kills (fatal hypertensive disease) and stroke. When you factor all that in as well, even your low, moderate alcohol consumption has health risks. The global health study, funded by the Bill and Melinda Gates Foundation looked at the burden that alcohol puts on 195 countries. The combined study population was 28 million individuals.

Alcohol related deaths and diseases

649, 000 registered cases of various deaths occurred due to alcohol. This included deaths from traffic accidents, injuries, cancer, heart disease and suicide. This global study compared the life expectancy and disease frequencies of alcohol-consuming people with non-alcohol consuming people. It concluded that non-alcohol consuming people live on an average up to 10 years longer than their alcohol-consuming counterparts. No studies up to now have been that comprehensive. The results from twenty-eight million people speak for themselves, and the death statistics are clear. It is worthwhile to look at the details and draw your own conclusion.

The Best Foods For Your Heart

In the following I will describe 16 foods, which are the best foods for your heart. I will also comment as to why I believe they are best. This review is based on this article in “Medical News Today”.

But I have added many other comments to it.

Heart disease is still the number 1 killer. We need to change what we eat.

Vegetables

The regular intake of green leaf vegetables and cruciferous vegetables (broccoli, cauliflower and cabbage) has an association with the  preservation of cognitive function. In the Nurses’ Health Study starting in 1984 women were asked about their usual intake of a specified portion of food items, including 15 fruits and 28 vegetables. At a later date, between 1995 and 2001, researchers decided to ask the oldest participants (70 years and older) to participate in a cognitive function study. Two years later researchers repeated these tests.The main finding of the study is that women with the highest intake of green, leafy vegetables had the least decline in their cognitive function. The vegetable lovers, who consumed five serving of cruciferous vegetables, like broccoli, cabbage and cauliflower had less decline in their cognitive function. On the other hand the highest decline showed up in the group that averaged only 2 servings per week.

Asparagus

Asparagus is a source of fiber, folate, multiple vitamins and chromium. Chromium enhances the function of insulin to transport sugar into cells. Asparagus contains glutathione, a powerful antioxidant that neutralizes free radicals and carcinogens. It is said to help prevent lung cancers, larynx cancer, and bone, breast and colon cancers.

Berries

Berries like strawberries, raspberries, blackberries and blueberries are full of bioflavonoids. These are antioxidants, which prevent cardiovascular disease.

It is the anthocyanines, which prevent oxidation of LDL cholesterol. Berries also have bioflavonoids and reduce lipid formation in the blood. Berries contain fiber, folate, iron, calcium, vitamin A, and vitamin C.

Broccoli

This fiber rich vegetable helps to prevent hardening of the arteries. Broccoli and kale likely have preventative effects against colon cancer.

Chickpeas, beans, peas and lentils

Legumes or pulses are a great way to consume plant-derived protein. People who are on vegan diets should be eating them for a protein source. They also contain lots of fiber, vitamins and minerals. We know that they lower cholesterol, which prevents heart disease. Other healthy nutrients they contain are bioflavonoids, which have antioxidant properties and help prevent cardiovascular disease.

Dark chocolate

This is a food rich in antioxidants. Dark chocolate is chocolate with more than 70% cocoa content. Please note: “milk chocolate” is nothing better than candy and devoid of any health benefits. Dark chocolate increases the protective HDL cholesterol and prevents oxidation of LDL cholesterol. It is said to prevent atherosclerosis (hardening of the arteries). Don’t exceed eating 1 to 2 oz. per day, as chocolate has some sugar in it and the fat content would be detrimental with higher consumption.

Chia seeds and flaxseeds

Chia seeds and flaxseeds are rich in omega-3 fatty acids in the form of α-linolenic acid (ALA). ALA reduces LDL cholesterol and it dissolves plaque in the arteries. ALA also reduces blood pressure to a certain degree. All of this helps reduce cardiovascular disease (heart attacks and strokes). Note that flaxseeds must be ground to powder to release the nutrients from its tough shell. Both chia and flaxseeds can be used as an egg replacement in vegan cooking.

Fish high in omega-3s

Omega-3 fatty acids are abundantly present in fish. It has plaque-reducing properties and also reduces the risk for abnormal heart beats. Overall this means less cardiovascular disease. The American Heart Association recommends a 3.5 oz. serving of fatty fish (salmon, mackerel, lake trout, herring or sardines) twice per week.

Coffee

A Brazilian study from 2018 showed that drinking 3 cups of coffee a day would stop coronary artery calcification. Many other studies have shown reduced mortality from heart attacks and strokes with increased coffee intake.

Green tea

Green tea is known to reduce blood pressure slightly and to reduce cholesterol. Both effects are beneficial for the cardiovascular system (prevents heart attacks and strokes). Green tea also prevents many cancers. Whatever we know about coffee consumption seems to also be true for green tea consumption.

Nuts

Nuts contain healthy fatty acids (omega-3). But they also contain fiber, protein, minerals, vitamins and antioxidants. Use them in desserts, in salads and as a quick food on the go. They are definitely healthier than protein bars.

Liver

Liver is one of the nutrient rich foods. It is rich in iron, phosphorus, vitamin A, folate, vitamin B12 and biotin.

Oatmeal

Oatmeal is rich in soluble fiber. It has been shown to lower LDL cholesterol and total cholesterol. This is important for prevention of heart disease.

Red wine (may be)

The bioflavonoids of red grapes have been the subject of much research. There is a dose-response curve showing a protective effect with regard to heart attacks and strokes with the consumption of  1 to 3 glasses of red wine per day. But unfortunately there is also a dose-response curve with respect to alcohol consumption and cancer causation. Personally, I take resveratrol from the health food store, 500 mg daily and consume white wine or red wine very rarely.

Tomatoes

There are a number of beneficial phytochemicals in tomatoes. Carotenoids like lycopene, lutein, zeaxanthine and beta-carotenes are helping to prevent prostate cancer and colon cancer. Potassium and folate are cardioprotective.

Spinach

Eating spinach regularly will provide you with magnesium, iron and bioflavonoids. Magnesium is good for a regular heart rhythm. The other nutrients are good for skin, bone and hair health.

Discussion

I have reviewed why these 16 foods are the best foods for your heart. We have seen that many foods that are rich in antioxidants are also cancer preventative. People who eat a Mediterranean diet will get these 16 foods, because their meals are balanced with nutrients. But if you eat a hamburger or a pizza you will not get balanced nutrients. The more one-sided your food intake, the more dangerous your lifestyle becomes. This is the problem with the Standard American diet (“SAD”). You need all of the components of the 16 foods described here. Junk food won’t do, as it consists only of empty calories.

The Best Foods For Your Heart

The Best Foods For Your Heart

Conclusion

It is useful to review healthy foods as was done above. Now it is a matter of including them in your daily food intake. If this is overwhelming you, start with baby steps. One or two healthy foods here or there are a good start. Increase this until you cover all the 16 foods mentioned. The more balanced your food intake is, the more antioxidant vitamins you will get. And the more heart disease and cancer prevention you will experience.

Apart from good, balanced nutrition we also need regular exercise for heart disease and cancer prevention. Go to a gym, go for a walk, climb some stairs. Get away from the computer and television. Together with best foods for your heart this will keep you healthier for longer.

Moderate Carb Intake Has The Lowest Mortality

A 25-year long study has shown that a moderate carb intake has the lowest mortality. A comprehensive study from the US has followed more than 15,000 men and women for 25 years. They were between 45-64 years when they entered the study and they were from diverse socioeconomic backgrounds. The authors chose mortality as an end point. Dr. Sara Seidelmann is a clinical and research fellow in cardiovascular medicine from Brigham and Women’s Hospital in Boston. She was the lead author of this study. The research group used food questionnaires and analyzed the carb content in the food. They also determined what percentage of the food composition was of animal origin or plant origin.

Research study finds moderate carb intake has the lowest mortality

The main findings of the study were that less than 40% of carbs in the diet led to an increased death rate with a mortality of between 1.4-fold and 1.8-fold. On the other hand, more than 70% of carbs in the diet also had increased mortality rates of 1.2-fold. The lowest mortality was in the group that consumed a diet where carbs were between 50% and 55%. Dr. Seidelmann explained that in terms of life expectancy the result of the study could be summarized as follows. A 50-year-old person had another 33 years to live when carb intake was in the moderate range. The low-carb person had only another 29 years to live (4 years less than the moderate carb person). The high-carb person lived another 32 years, 1 year less than the moderate carb person.

Plant-derived versus animal-derived fat and protein

The study showed that there was increased longevity when carbohydrates were exchanged for proteins and fats from plant sources. Mortality was 18% less for this group. Conversely, when carbs were replaced for animal-derived fat or protein mortality was 18% more!

Dr. Seidelmann noted that this study was coming from a US based population. In the case of an Asian group they would consume much more carbs on average, but they would replace a lot of the animal fat and protein with fish. Fish is a healthier source of protein and fat than beef or pork.

A moderate carb intake group that used protein and fat from animal sources was compared to plant sources. When protein and fat had the origin from lamb, beef, pork, and chicken the mortality over 25 years was higher. When protein and fat came from vegetables, such as nuts, peanut butter, seeds and whole-grain breads there was a lower mortality rate.

Other studies comparing the effect of animal protein versus plant protein

  1. A 2016 study that had gone on for 49 years was involving 131,342 participants. Animal protein intake showed an association with higher mortality from heart attacks and strokes. 3% of energy from processed red meat was now substituted by an equivalent amount of plant protein. This reduced the all-cause mortality by 34%, for unprocessed red meat by 12% and for egg by 19%.

 

  1. Red meat is cancer-producing. Several studies have shown this. When red meat is digested, cancer-causing substances are released that can be the cause of cancer in the lining of the stomach and the colon. The above link says we should limit red meat consumption to 65 grams (2oz.) per day or 2 servings (130 grams or 4 oz.) 3 to 4 times per week. We should avoid eating more than 455 grams (1 pound) of lean red meat per week.

Triglycerides are an independent risk factor for heart attacks

In this publication evidence is also present that triglycerides are an independent risk factor that can cause heart attacks.

When you eat too many carbs, the body produces the excess you don’t need into triglycerides, and it deposits its subsequently as fat in fatty tissue.  Physical activity burns up some of the triglycerides. But when we eat too much refined sugar and starchy foods, there will be an excess of triglycerides putting our blood vessels and our hearts at risk.

Regular exercise prevents disease and premature deaths

Many studies have shown that regular exercise prevents heart attacks and premature deaths. We even know the mechanism of why this is so. Exercise releases nitric oxide ((NO) from our blood vessels, which widens the arteries. This also prevents high blood pressure. Exercise elevates the protective HDL cholesterol. When regular exercisers were compared to a non-active group they had a 41% lower risk of death. All-cause hospitalizations were down by 21% and cardiac hospitalizations were down 32%.

Discussion

  1. Barry Sears is the inventor of the Zone Diet. I attended a lecture in 2001 at an Anti-Aging Conference in San Diego. Dr. Sears was the keynote speaker at this conference. He stressed that a diet with 55% of complex carbs would be the best diet. It is interesting that Dr. Seidelmann in the study mentioned in beginning of this blog found the same thing. The lowest mortality was in the group that consumed a diet where carbs were between 50% and 55%.
  2. The second point that is important to note is that it matters whether we eat protein derived from animals or from plants. Even small steps help. When we reduce our animal protein intake by only 3% of the energy intake, and replace it by plant protein, there is a significant reduction in mortality.
  3. Exercise is rarely mentioned in relation to diets. But exercise needs to be included every day and you will experience a reduction of cardiac hospitalizations of 32% as mentioned above.
Moderate Carb Intake Has The Lowest Mortality

Moderate Carb Intake Has The Lowest Mortality

Conclusion

A moderate carb intake, as is the case in the Mediterranean diet and in the Zone Diet of Barry Sears, has the lowest mortality rate. Complex carbs (in vegetables) are absorbed much slower. As a result the risk for heart attacks is much lower. The opposite is true for refined carbs from sugar. They cause heart attacks and strokes with premature mortality. Dr. Sara Seidelmann led a study at the Brigham and Women’s Hospital in Boston that lasted 25 years. Less than 40% of carbs in the diet led to an increased death rate with a mortality of between 1.4-fold and 1.8-fold. These diets are paleo-type diets, the Atkins diet and the ketogenic diet. More than 70% of carbs in the diet also had increased mortality rates of 1.2-fold.

The healthiest diet

People who consumed a diet where carbs were between 50% and 55% had the lowest mortality rate (Zone Diet). Another finding of this study, which was confirmed by others is that animal-based protein is unhealthier than plant-based protein. Even replacing 3% of energy from an animal-based diet with plant-derived protein delayed mortality significantly.

If you want to live longer and stay healthy you need to critically evaluate what you eat.
