Metabolism Can Vary in People

Weight loss is easier for some than others, because metabolism can vary in people. In the following I will outline this in more detail. A biochemist recently published an article in “the conversation”, which is the basis for my review.

Everybody has their own metabolism

It is important to realize that everything that our body comes in contact with influences our physical characteristics like our blood pressure and our energy. Together all the biological characteristics have the name phenotype. The most important factor that influences our phenotype is our metabolism. It matters what you do like eating, whether you are taking medication, smoking, or exercising. This all influences your metabolism. On a molecular level it starts when your digestive system breaks nutrients down into each component: carbohydrates, fats and protein. When your digestive juices break down these food components, electrons are released from chemical bonds. These are transferred to the mitochondria, the energy packages in all of our cells. It is important to note that we do not all have the same metabolism as our neighbour. There are different types of metabolism.

Metabolism of an elite athlete

Elite athletes are not born that way. They have to practice hard physically for many hours a day and do that over several years. Their bodies adapt to the regular training by creating extra mitochondria in every cell of their body. Their body also learns how to burn fat, carbs and amino acids into chemical energy effectively. The elite athlete has superior energy production.

Metabolism of a Covid-19 patient

At the other end of the spectrum is the metabolism of a Covid-19 patient. Researchers found by examining patients who got sick from Covid-19 that their fat metabolism was impaired. This inability to burn fat persists in long Covid patients. The fatigue from long Covid is due to a dysfunction of the mitochondria. The mitochondria are not producing enough energy.

The in-between metabolism of blood donors

Travis Nemkov is an assistant research professor at the University of Colorado Anschutz Medical Campus. His team investigated blood from 13,000 blood donors. They found that the metabolism of blood donors placed between the metabolism of elite athletes and that of Covid-19 patients. They also found a lot of variation of a metabolite by the name of kynurenine, which is due to a breakdown of the amino acid tryptophan. The researchers found that blood from donors with higher kynurenine levels was unable to restore blood levels of blood recipients. In addition, they found that kynurenine levels were higher in older donors and also in patients with obesity (higher BMI’s). Kynurenine was also a strong predictor for Covid-19 severity.

Weight loss problems when the metabolism is slow

We all know people who have a problem shedding their weight compared to others who loose weight with only a few days of food restriction. “People might have fast, slow, or average metabolism, regardless of their body size and composition,” says Dr. Chih-Hao Lee, professor of genetics and complex diseases at Harvard’s T.H. Chan School of Public Health. This Harvard University website explains this in detail. How do we speed up a naturally slow metabolism?  We can exercise a bit more, and watch the quality of our food intake. This means cutting out added sugar, too much fat, too many carbohydrates and processed foods. The Harvard website says: “Studies have found green tea contains a compound called epigallocatechin gallate, which may increase the calories and fat you burn. “By making these small changes mentioned you can rev up your metabolism.

Hormones and body weight

Our metabolism and body weight depend on a number of hormones: leptin, insulin, estrogens, androgens and growth hormone play a crucial role in weight control. Additional hormones, such as the thyroid hormones are involved in maintaining our weight in a healthy range. Researchers have noticed that patients with hypothyroidism gain weight and burn less calories in their mitochondria. On the other hand, patients with hyperthyroidism stimulate their metabolism, lose weight and burn more calories. The exact mechanism of how thyroid hormones interact with the other hormones is unknown.

Metabolism Can Vary in People

Metabolism Can Vary in People

Conclusion

I came across a review about metabolism and weight control, written by a biochemist. He pointed out that different people have different metabolisms. Examples he gave were the metabolism of elite athletes and the metabolism of Covid-19 patients, who are at the low end. His team investigated the metabolism of 13,000 people who were blood donors. He called them people with an in-between metabolism.

How to speed up naturally slow metabolism

How do we speed up a naturally slow metabolism?  We can exercise a bit more, and watch the quality of our food intake. This means cutting out added sugar, too much fat, too many carbohydrates and processed foods. Your physician can also tell you whether your thyroid hormones and your human growth hormone are adequate. Other hormones that regulate your metabolism are leptin, insulin, estrogens and androgens. When you look at the factors that are responsible for your metabolism, the genetic factors come first. Your hormone status, eating pattern and exercise status come second. But by making small changes to the factors mentioned you can rev up your metabolism significantly.

Living with the Aging Process

The following article describes living with the aging process. Older adults undergo the process of aging between the ages of 50 and 80. This is a complex process affecting various systems parallel. There are hormone factors that are particularly prominent in women during menopause. Joints are affected by degenerative changes, which can lead to total knee and hip replacements. The aging process was described in an article by Monica Jimenez at Tufts University.

What is aging?

Aging is the loss of function over time. The body is much more complex than a car, so there are more possible points of failure.  Christopher Wiley is a scientist on the Basic Biology of Aging Team who studies the role of nutrition and metabolism in aging at a cellular level at Tufts University. He said:” The fact that life works is amazing”. He went on to say: “The body tries to maintain itself and restore homeostasis(self-healing) even in the face of all this stress and all this damage. We have these really sophisticated programs for dealing with these points of failure.”

Aging goes on relentlessly

He explains the aging process this way: “It can start with something as simple as a broken molecule, one little thing that goes wrong in one cell, and then it’s like the butterfly effect,” Wiley said. “The tissue starts struggling, and then the organ, and then your entire body.”

Dr. Wiley warns about those who say physicians could make people “immortal”. “There’s definitely a misconception out there that we’re trying to make people immortal. But there is never going to be an immortality vaccine,” Wiley said. “There’s never going to be one thing that defeats all of aging. There’s always going to be another point of failure.”

Slowing down biological aging

The emphasis of research about aging is not to add chronological years. It is on biological aging and on how well our cells and tissues are functioning. Dr. Sarah Booth is the director of the Human Nutrition Research Center on Aging (HNRCA) at Tufts. She said: “Lengthening the time in which we can continue to move around, care for ourselves, and participate in social life and activities, is a worthier goal than extending years of suffering.” Many people become disabled in their last years of life, then they die. “Healthspan” is a new term for our years of freedom from disability, Booth noted.

Factors that prolong healthy aging

  1. Telomere length: One of the factors of longevity is our telomere length. Telomeres are the protective caps at the end of each chromosome. When they wear down, it leads to mistakes in the DNA copies of genetic information. There are supplements and herbs that can elongate telomeres. Exercise and the fasting mimicking diet also make telomeres longer. Older adults in good shape have longer telomeres, which stabilizes the DNA in their cells.
  2. Healthy diet: Researchers have determined that several diets are healthier than others. The Mediterranean diet is anti-inflammatory, so is the DASH diet, which was developed for people with high blood pressure. The HNRCA of Tufts is one of six organizations that got research grants recently to investigate life-prolonging diets. The amount was for $8.5 million.

Exercise and lifestyle factors

  1. Regular exercise: Over the years a lot of research accumulated data that shows regular exercise makes people biologically younger. Heart vessels have less atheromatous deposits and the brain stays younger as well. One study reported that 30 minutes of exercise daily prevents dementia.
  2. Other lifestyle factors: other factors are whether or not you are smoking (it goes without saying that you must quit). In addition, genetics (longevity gene), the environment (polluted or not), stress levels and socioeconomic class all play a factor in how fast we age. These latter points are difficult to tease apart, but they influence us globally. Target organs for aging are: the brain, heart, eyes, and bones, along with cancer, obesity, and more.

Hormone replacement 

  1. Bioidentical hormone replacement: One factor about delaying aging significantly was not mentioned in the review article by Monica Jimenez. But I am including it, because bioidentical hormone replacement is important for women who undergo menopause in their 50’s. I also mention it because men enter andropause in their 60’s. BiEst estrogen and progesterone cream make a big difference for the symptoms of menopausal women. Similarly, men experience a lot of relief with testosterone injections twice a week, when blood testosterone levels are low. If they have a lack of erections (erectile dysfunction) they may in addition need to take the “happy pill”. Sildenafil or tadalafil can treat erectile dysfunction by giving a good erection to a menopausal male. Hormone replacement can add as much as 10 healthy years to your life.

Discussion

Dr. Booth said: “We’re looking at the same question through different lenses with different tools, technologies, and perspectives. Progress in aging research is only going to be achieved by bringing together different disciplines addressing the same problem.”

Christopher Wiley added: “The biggest change I’ve seen in the past ten years is that we really are finding new, different ways of actually intervening somewhere that could potentially extend the healthy years of life, and prevent people from getting age-related diseases.” He mentioned that scientists are gradually reducing the suffering associated with aging: “What aging research is really trying to do is compress the morbidity and make it as small as possible – to alleviate suffering,” Wiley said. “I think that’s a much more humanitarian goal, and I think we’re having a lot of success with those efforts.”

Living with the Aging Process

Living with the Aging Process

Conclusion

Aging is a slow process that starts the moment we are born. But between the age of 50 and 80 we age faster. I mentioned 5 specific areas that can slow down the aging process. If somebody smokes, he/she must stop smoking. Cigarette and tobacco smoking  the biggest aging factor. The protective caps at the end of each chromosome go by the name of telomeres. When they shorten prematurely, mistakes occur in the DNA copies of genetic information. This leads to premature aging.

What keeps you younger for longer

The good news is that exercise, the fasting mimicking diet and several supplements can elongate telomeres. A healthy diet like the Mediterranean diet and regular exercise keeps the arteries open preventing heart attacks and strokes. Bioidentical hormone replacement helps to rebalance your hormones, which is important for normal cell function. In anti-aging circles they talk about life prolongation of about 10 years for hormone replacement alone. It comes down to not simply extend your lifespan, but to extend your years of healthy living without disability.

Effects of a Plant-centered Diet on Cardiovascular Disease in Midlife

A study followed younger patients for 32 years looking for the effects of a plant-centered diet on cardiovascular disease in midlife. The researchers determined the heart attack and stroke rates when the participants were in their 50’s to 60’s. When on a plant-based diet cardiovascular disease rates fell by 52% compared to a control group with a meat containing diet. One subgroup changed the diet from a regular diet to a plant-based diet over 13 years. This reduced the risk ratio by 61% for heart attacks and strokes when assessed later.

Details of this study

There were 4946 adults as participants of this 32-year study. They were recruited in 1985 and 1986, at which time none of them had cardiovascular disease. The study completed in 2018. The results were published on Aug. 4, 2021. The researchers assessed the plant-centered diet quality using a tool with the name “A Priori Diet Quality Score” (APDQS). The higher the score, the higher the quality of the food. This means the person consumed nutritionally rich plant foods, limited amounts of high-fat meat products and less healthy plant foods.

Although a plant-rich diet consisted primarily of nutritionally rich plant foods, small amounts of animal products were also allowed. This involved low-fat dairy products, non fried poultry and steamed or grilled fish. This made the diet tastier and ensured that people would stick to this diet for decades.

Improvements of heart attack rates with plant-centered diet

After 32 years 289 cases of cardiovascular disease developed. The researchers compared participants with the highest food quintile to participants with the lowest food quintile. As mentioned, the risk for participants on a plant-based diet was 52% lower to get a cardiovascular disease. Moreover, a subgroup changed from a higher risk (fatter meals, meat, less vegetables) diet to a lower risk diet (lean fat, lean poultry, vegetables). Physicians followed this subgroup for 13 years and the risk ratio for heart attacks and strokes fell by 61%.

Comparison to other diet studies

There are other studies that looked at the effect of diet changes on the risk of developing heart disease. One such study examined 86 cross-sectional studies and 10 prospective studies in a meta-analysis. Vegetarian diets reduced deaths from heart attacks by 25% and brought down the incidence of total cancer rates by 8%. A vegan diet reduced the risk of total cancer by 15%.

In a study from the United Kingdom dated March 2019 several clinical trials were analyzed regarding non-diabetic populations. The question came up, what the effect of a Mediterranean diet was on cardiovascular disease incidence and mortality. The authors reviewed 30 RCTs (49 papers) with 12,461 randomized participants and seven ongoing trials. In one study the observation time was 46 months. A Mediterranean diet reduced the cardiovascular disease mortality by 65%!

Another study from Spain

Another study from Spain published in 2019 examined 7356 older adults (average 67 years) and followed them for 6.8 years. The investigators kept track of the physical activity and put everybody except the controls on a Mediterranean diet. The group on the lightest leisure-time physical activity consuming a Mediterranean diet had the lowest mortality. The all-cause mortality of this group was 73% lower than the control group.

What is so healthy about the Mediterranean diet?

Despite a wide variation between all the 15 countries bordering the Mediterranean Sea, there are common characteristics: an abundance of vegetables and fruit, along with nuts and legumes. Cereal products are largely whole grain. Olive oil is the principal fat source, and people eat fish, seafoods and poultry in moderation. They consume red meat rarely. Cheese and yogurt can be part of the diet, depending on the region.

The first clinical evidence supporting the health benefits of the Mediterranean diet came from the Lyon Heart Study. The researchers placed patients who had a heart attack either on the diet designed by the American Heart Association or a Mediterranean style diet. After a follow-up of 27 months, the group eating the Mediterranean diet had a reduction of heart attacks by 73% and a decreased mortality by 70% compared to the other group.

More detail on the ingredients of the Mediterranean diet

An analysis of the various foods of the Mediterranean diet shows the reasons for the health benefits clearly. The fats that people on a Mediterranean diet eat are heart-healthy monounsaturated fats like olive oil or fats that contain omega-3 fatty acids. They come from fish (tuna, salmon, trout, sardines) or from plant sources (walnuts, other tree nuts and flax seed).

As there is an emphasis on natural foods, the diet is extremely low in trans fatty acids (hydrogenated fats), which otherwise increases the risk for cardiovascular disease. As people consume more than 300g of vegetables per capita daily, the contents of antioxidants and other beneficial plant chemicals is much higher in comparison to Western diets. There are many individual components of the Mediterranean diet that contribute to the reduction of disease. This is particularly true for heart disease. It also is apparent, that there is not one single food or nutrient that is responsible for the health benefits. What matters are the interactive effects of all the nutrients that lead to the health benefits.

No processed food means healthier living

The practical application does not mean deprivation and starvation, but a move away from processed fats (margarine), baked goods (donuts, muffins, pastries), and high saturated fat snacks and trans fats (chips, crackers, cookies, pies). Food choices move towards those of fresh fruit and vegetables, nuts, fish, and olive oil. Portions or servings have to be adequate to maintain a healthy weight.

Mediterranean food is not the heaping plate of pasta with an afterthought of vegetables. It also is not the super-size fast food pizza with pepperoni and cheese. Mediterranean food incorporates fresh food rather than fast food. It entails a shift from large portions of red meat to smaller portions of fish, a transition from highly processed foods to ample helpings of dark green vegetables with a dose of olive oil. Low amounts of alcohol, especially red wine can make a meal enjoyable, which means that the limit is one drink per day for women, and two drinks per day for men. After dinner go for a walk!

Olive oil is one of the reasons why the Mediterranean diet is so healthy

In the past it was thought that the monounsaturated fatty acids in olive oil would be the reason why it is protective of the heart. However, newer studies have shown that it is the polyphenols and among these in particular hydroxytyrosol that lower blood pressure and protect you from hardening of the arteries.

A 2012 study from Spain has found that mortality from heart attacks was 44% lower than that of a control group who did not incorporate olive oil in their diet.

How polyphenols in olive oil work for you

Only two tablespoons of extra virgin olive oil per day protect you from heart disease. It does so by reducing the total cholesterol level in the blood as well as the LDL cholesterol level. When there is more polyphenol in olive oil (such as in extra virgin olive oil), the body produces more HDL, which is essential to extract oxidized LDL from arterial plaque. On top of that polyphenol rich olive oil increases the size of the HDL particles (these larger particles have the name HDL2), which are more efficient in extracting oxidized LDL from arterial plaques. A Sept. 2014 study in humans showed that higher polyphenol olive oil as found in extra virgin olive oil caused an increase in the more effective HDL2 particles. This cleans out plaques from arteries more effectively than the regular, cheaper olive oil.

Effects of a Plant-centered Diet on Cardiovascular Disease in Midlife

Effects of a Plant-centered Diet on Cardiovascular Disease in Midlife

Conclusion

Several large, well-controlled studies showed that there are pronounced effects of a plant-centered diet on cardiovascular disease in midlife. Heart attack rates and mortality rates were reduced by 25% to 73% on a Vegan diet or a Mediterranean diet. When people combine a plant-centered diet with regular physical exercise they also live longer. One of the ingredients of a Mediterranean diet is extra virgin olive oil. It contains polyphenols that lower total and LDL cholesterol. It also increases the larger particles of HDL cholesterol with the name HDL2. HDL2 is more efficient in extracting oxidized LDL cholesterol from arterial plaques.

What you can eat on a plant-centered diet

A plant-centered diet incorporates fresh food rather than fast food. It entails a shift from large portions of red meat to smaller portions of fish, a transition from highly processed foods to ample helpings of dark green vegetables with a dose of olive oil. Instead of large portions of beef and sausages shift to seafood (tuna, salmon, trout, sardines), walnuts, other tree nuts and flax seed. The statistics clearly showed the effects of a plant-centered diet on cardiovascular disease in midlife with a reduction of heart attacks and mortality.

Mother’s Lifestyle Predicts Heart Attack Risk for Offsprings

A European Society of Cardiology study found that mother’s lifestyle predicts heart attack risk for offsprings. This study was published in the Journal of Preventive Cardiology, a journal of the European Society of Cardiology. It was also summarized in Science Daily. The study author Dr. James Muchira of Vanderbilt University, Nashville said: “This maternal influence persists into the adulthood of their offspring.” What he meant is that the study found that lifestyles of mothers influence the choices of lifestyles of the offsprings, and with poor choices even determine when the next generation gets their heart attack or stroke.

In previous research the team established that both genetic factors as well as environmental and lifestyle factors are responsible for cardiovascular disease. Now the researchers wanted to determine the influence of each parent on the risk of cardiovascular disease of the offspring.

Set-up of the study

The study was done with offspring and the parents of the Framingham Heart Study. 1989 children from 1989 mothers and 1989 fathers were enrolled 1971 and followed for 46 years. The average age of the offspring at enrolment was 32 years. The study ended 2017. Dr. Muchira said: ”Crucially, the study followed children into most of their adult life when heart attacks and strokes actually occur.”

Risk factors for cardiovascular disease

The researchers rated the risks of fathers and mothers in the study according to 7 factors.

  • Smoking status (non-smoker preferred)
  • Diet (healthy or not)
  • Physical activity
  • Body mass index (normal or not)
  • If blood pressure is too high
  • Level of blood cholesterol
  • Blood sugar values

The researchers established three categories of cardiovascular health: poor (fulfilment of 0 to 2 factors); intermediate (fulfilment of 3 to 4 factors) and ideal (fulfilment of 5 to 7 factors). The researchers wanted to know how long the offspring were able to live without symptoms of cardiovascular disease.

Findings of the study

Here are the findings of the study.

  • Children of mothers with ideal cardiovascular health lived free of cardiovascular symptoms for 27 years; they were on average 32+27= 59 years when symptoms started.
  • Children of mothers with poor cardiovascular health lived free of cardiovascular symptoms for 18 years; they were 32+18= 50 years old when symptoms started; this is 9 years earlier than children from mothers with ideal cardiovascular health.
  • Father’s cardiovascular health did not influence the children’s onset of cardiovascular symptoms.

Cardiovascular risks of the children are due to a combination of things

A combination of the health status during the pregnancy and the environment in early life influenced the children.

Dr. Muchira said: “If mothers have diabetes or hypertension during pregnancy, those risk factors get imprinted in their children at a very early age. In addition, women are often the primary caregivers and the main role model for behaviors.” Sons were much more affected by their mother’s cardiovascular health status. Dr. Muchira explained: “This was because sons had more unfavourable lifestyle habits than daughters, making the situation even worse. It shows that individuals can take charge of their own health. People who inherit a high risk from their mother can reduce that risk by exercising and eating well. If they don’t, the risk will be multiplied.”

Discussion

We remember that the Framingham Heart Study long time ago established the above-mentioned risk factors for heart disease. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4159698/ It is also important for the offspring to quit smoking as this is a high-risk factor for heart disease. Next eat a balanced diet, like the Mediterranean diet. With this you eat more vegetables, less meat, more fish and add olive oil. Engage in regular exercise, which will raise the protective HDL cholesterol. Keep your body mass index low (in the 21.0 to 22.0 range, but definitely below 25.0). Keep your blood pressure in the normal range (120/80 or less). Make sure that your blood cholesterol and blood sugar values are normal. This will give you the lowest risk to develop a heart attack or a stroke.

Mother’s Lifestyle Predicts Heart Attack Risk for Offsprings

Mother’s Lifestyle Predicts Heart Attack Risk for Offsprings

Conclusion

We are normally concerned about our own cardiovascular health. But in a new study researchers examined children of participants in the Framingham Heart Study and their parents. This showed that the cardiovascular health status of the mother had a significant influence on the children’s  cardiovascular health. The offspring had an average age of 32 years when the researchers started to follow them for 46 years. When the mother was in poor cardiovascular health, the offspring developed cardiovascular symptoms at age 50. But when the mother’s cardiovascular health was ideal, the children got symptoms of cardiovascular disease only at age 59. This delay of 9 years of disease onset was purely due to the mother’s cardiovascular health status.

Risk management of cardiovascular risks

The authors of the study say that the children can do a lot to minimize the cardiovascular risk. They need to work to reduce the known risk factors and also start a regular exercise program. The authors of the study mentioned that even people who inherited a risk for cardiovascular disease benefit significantly from cutting out risk factors for cardiovascular disease.

Medical Myths about Aging

Medical myths about aging are easy to debunk. Many people believe that it is inevitable that they become disabled as they age, their lives become unbearable, without passion, boring and full of pain. Some aspects of your health may decline with age, none of the myths discussed below is inevitably happening in everyone. Studies showed that a positive outlook on aging and life in general will help you to live longer and stay healthier.  Here I discuss 7 common myths about aging.

Myth 1: Everyone will experience physical deterioration

It is common for people to experience reduced muscle strength, increased blood pressure, excessive fat accumulation and osteoporosis. A study with 148 older patients showed that an expectation of reduced fitness in older age actually resulted in less physical activity when older age arrived.

But you can maintain good cardiovascular function and good muscle strength with a regular exercise program.  This study showed that men and women can reduce mortality by exercising regularly, even in older age.

Myth 2: Older adults cannot exercise

There are several reasons why older people stop exercising or are afraid to start exercising. People use the excuse of their arthritis getting worse from exercise. But studies showed the opposite: joint function improves and joint pains are getting better with exercise. Your muscles get stronger and you are less likely to fall. Your heart and lungs are improving their functions and your mentation improves. Exercise increases the HDL cholesterol, which reduces the risk for heart attacks and strokes.

Myth 3: As we age, we need less sleep

For many years there was the notion that older people need less sleep. What was not known then was that people above the age of 60 have no appreciable secretion of melatonin from the pineal gland. But when they replace their melatonin deficiency by taking a nighttime dose of 3 mg at bedtime, they will sleep better and longer. They may need a second dose of melatonin in the middle of the night. We need 7 to 8 hours of sleep at night for our diurnal hormone rhythm.

This will also slow down our aging clock.

Myth 4: Your brain slows as you age

Dementia is common when you get older. 13.9% have it at age 71 and older. 37.4% have dementia over the age of 90. But the majority, namely 86.1% in the 71+ age group and 62.6% above the age of 90 do not have dementia. A Mayo Clinic study showed that when the person engaged in artistic activities in midlife or later in life the risk for mild cognitive impairment (MCI) development was reduced by 73%, involvement in crafts reduced it by 45% and engagement in social activities by 55%. In a surprise finding the use of a computer late in life was associated with a 53% reduction in MCI development. These are very significant observations.

Physical activity reduces risk for dementia

Apart from stimulating your brain, physical activities also significantly reduce the risk for dementia. A synopsis of 11 such studies showed that dementia is reduced by 30% when physical activity is started in midlife and the person is aging compared to non-exercisers.

Myth 5: Osteoporosis occurs only in women

There is a serious misunderstanding about osteoporosis. Several factors work together that can cause osteoporosis. Women in menopause are more likely to develop it due to the missing ovarian hormones estrogen and progesterone. These hormones work together and stimulate vitamin D induced calcium deposition into bone as well as decreasing bone resorption.

Vitamin K2 also deposits calcium into the bone. In postmenopausal women who take bioidentical hormone replacement, vitamin D and K2 the bone density remains strong. Unfortunately, the opposite is true in postmenopausal women who take synthetic hormones. Synthetic hormones have side chains that do not fit the natural hormone receptors of a woman. This is why osteoporosis persist. And, yes, men get osteoporosis, but typically 10 years later. Typically, they get into andropause where testosterone production declines 10 years later.

Myth 6: People stop sex as they age

With age men can develop erectile dysfunction (ED) and women vaginal dryness, both of which can interfere with having sex. A large study showed that only 0.4% of men in the age group 18-29 had ED. In the age group of 60-69 there were 11.5% who suffered from ED. What this means though is that 88.5% of men age 60-69 did not suffer from ED. Fortunately for those who have ED drugs like Cialis and Viagra can correct their problem and they can have regular sex. What a change from 25 years ago when none of these drugs were available (approval of Viagra by FDA in 1998 and of Cialis in 2003).

Bioidentical hormone replacement beyond menopause and andropause preserves your normal sex drive as well. There are additional benefits of bioidentical hormones. They have positive effects on the heart, brain, bones and the muscle mass.

Myth 7: It is too late to stop smoking now

One of the myths that many older smokers like to say is that it would be too late to stop smoking. They think the damage to heart and lungs is permanent and quitting now is too late. Fact is that quitting smoking immediately improves your blood circulation and gives you more oxygen. In just 1 year the risk of getting a heart attack is cut into half. In 10 years, the risk of a heart attack or stroke is the same as that of non-smokers. There is a reduction of getting lung cancer by half.

Medical Myths About Aging

Medical Myths about Aging

Conclusion

There are all kinds of medical myths about aging. We may think that physical deterioration is inevitable. Or we believe that older people cannot exercise. And we cannot help it, but our brain slows down as we get older. And there is the question whether we need less sleep as we age. Osteoporosis is a disease of women, is it not? These older couples, they don’t have sex any more, do they? And is it too late to stop smoking now that I am 65 years old? All of these myths exist, but there is a need to debunk them.

The truth behind the medical myths about aging

I explained in detail what the medical truths are behind these questions. Many of these myths have developed in the past. But with regular exercise, balanced nutrition (Mediterranean diet) and a positive attitude much of these old myths can be overcome. Bioidentical hormone replacement when hormones are missing is another powerful tool. Yes, we all age. But we are still living and can enjoy life as long as it lasts.

Mediterranean Diet Reduces Heart Attacks and Strokes in Diabetes

A recent publication came to the conclusion that a Mediterranean diet reduces heart attacks and strokes in diabetes. This Canadian and Spanish study compared prospective cohort studies and randomized trials (RCT). 41 reports (3 RCTs and 38 cohorts) formed the basis for this analysis.

Details of the study

Metaanalysis showed that a Mediterranean diet reduced the cardiovascular disease incidence by 38%. It also reduced myocardial infarctions (heart attacks) by 35%. Next the authors compared the highest to the lowest adherents to the Mediterranean diet (Med diet). The highest Med diet adherents showed the following reductions:

Cardiovascular disease mortality: 21%

Coronary heart disease incidence: 27%

Coronary heart disease mortality: 17%

Stroke incidence: 20%

Stroke mortality: 13%

The conclusion was that the Mediterranean diet is beneficial to prevent heart disease and strokes in people with diabetes.

Other studies

In a study from the United Kingdom dated March 2019 several clinical trials were analyzed regarding non-diabetic populations. Again, the question came up, what the effect of a Mediterranean diet was on cardiovascular disease incidence and mortality. The authors reviewed 30 RCTs (49 papers) with12,461 randomized participants and seven ongoing trials. In one study the observation time was 46 months. A Mediterranean diet reduced the cardiovascular disease mortality by 65%!

Another study from Spain published in 2019 examined 7356 older adults (average 67 years) and followed them for 6.8 years. The investigators kept track of the physical activity and put everybody except the controls on a Mediterranean diet. The group on the lightest leisure-time physical activity consuming a Mediterranean diet had the lowest mortality. The all-cause mortality of this group was 73% lower than the control group.

The fats that people on a Mediterranean diet eat are heart-healthy monounsaturated fats like olive oil or fats that contain omega-3 fatty acids. They come from fish (tuna, salmon, trout, sardines) or from plant sources (walnuts, other tree nuts and flax seed).

As there is an emphasis on natural foods, the diet is extremely low in trans fatty acids (hydrogenated fats), which increase the risk for cardiovascular disease. As people consume more than 300g of vegetables per capita daily, the contents of antioxidants and other beneficial plant chemicals is much higher in comparison to Western diets. There are many individual components of the Mediterranean diet that contribute to the reduction of disease. This is particularly true for heart disease. It also is apparent, that it is not one single food or nutrient that is responsible for the health benefits. What matters are the interactive effects of all the nutrients that lead to the health benefits.

No processed food means healthier living

The practical application does not mean deprivation and starvation, but a move away from processed fats (margarine), baked goods (donuts, muffins, pastries), and high saturated fat snacks and trans fats (chips, crackers, cookies, pies). Food choices move towards those of fresh fruits and vegetables, nuts, fish, and olive oil. Portions or servings have to be adequate to maintain a healthy weight.

Mediterranean food is not the heaping plate of pasta with an afterthought of vegetables. It also is not the super-size fast food pizza with pepperoni and cheese. Mediterranean food incorporates fresh food rather than the fast food. It entails a shift from large portions of red meat to smaller portions of fish, a transition from highly processed foods to ample helpings of dark green vegetables with a dose of olive oil. Low amounts of alcohol, especially red wine can make a meal enjoyable, which means one drink per day for women, and two drinks per day for men. And after dinner go for a walk!

Olive oil is one of the reasons why the Mediterranean diet is so healthy

In the past it was thought that the monounsaturated fatty acids in olive oil would be the reason why it is protective of the heart. However, newer studies have shown that it is the polyphenols and among these in particular hydroxytyrosol that lower blood pressure and protect you from hardening of the arteries.

In a 2012 study from Spain it was found that mortality from heart attacks was 44% lower than that of a control group who did not incorporate olive oil in their diet.

How polyphenols in olive oil work for you

Only two tablespoons of extra virgin olive oil per day protect you from heart disease. It does so by reducing the total cholesterol level in the blood as well as the LDL cholesterol level. When there is more polyphenol in olive oil (such as in extra virgin olive oil), the body produces more HDL, which is essential to extract oxidized LDL from arterial plaque. On top of that polyphenol rich olive oil will increase the size of the HDL particles (these larger particles are called HDL2), which are more efficient in extracting oxidized LDL from arterial plaques. A Sept. 2014 study in humans showed that higher polyphenol olive oil as found in extra virgin olive oil caused an increase in the more effective HDL2 particles, which cleans out plaques from arteries more efficiently than the regular, cheaper olive oil.

Endothelial function

The endothelium is the lining of the arteries. Normal endothelial functioning involves widening of the arteries and maintaining its flexibility. The body achieves this through production of a signal molecule, called nitric oxide; the endothelial cells that line our arteries from inside produce it. Exercise increases the production of nitric oxide as well (Ref.1).

In a group of patients with poor endothelial function 2 tablespoons of olive oil (polyphenol rich) per day given over 4 months (the time of the study) showed a significant improvement of endothelial function.

The authors suggested that an enzyme in the endothelial cells, called nitric oxide synthase is being stimulated by components of polyphenol-rich olive oil. This leads to protracted release of nitric oxide, which in turn keeps blood vessels flexible and wide open. Other investigators found that olive oil can influence even a hereditary gene variant of endothelial nitric oxide synthase found in people with a history of premature heart attacks. This high-risk group of people should take extra virgin olive oil regularly to prevent premature heart attacks and strokes.

Endothelial dysfunction occurs when the arteries no longer can deliver adequate amounts of blood to vital organs like the heart or the brain. Endothelial dysfunction is also present in patients with type 2 diabetes, obesity, high blood pressure and metabolic syndrome. Introducing extra virgin olive oil in the diet of these patients will help restore their endothelial function.

Lowering blood pressure

In a study on 23 hypertensive patients it was shown as far back as in 2000 that extra virgin olive oil over 6 months allowed physicians to reduce high blood pressure medications by 48%. When the study was crossed over, the reverse was the case for the control group on sunflower oil. The polyphenols of olive oil released nitric oxide, which is known to lower blood pressure. This is an important finding. High blood pressure is a risk factor for the development of hardening of the coronary arteries. This leads to heart attacks, congestive heart failure, but also stroke. Regular intake of 2 tablespoons of extra virgin olive oil often will reverse high blood pressure and restore normal endothelial function.

Preventing heart attacks and strokes

In April of 2013 The New England Journal of Medicine published a Spanish diet study that showed that a participants on a Mediterranean diet with olive oil or nuts had 30% less heart attacks over 5 years than people on a low fat control diet. Other studies have also shown that olive oil and omega-3 fatty acids play a big role in preventing heart attacks and strokes. We also know that regular exercise reduces the risk further; so does keeping your body mass index below 25.0. Extra virgin olive oil is part of the protection from heart attacks and strokes. The study did not show any protection against cancer.

Mediterranean Diet Reduces Heart Attacks and Strokes in Diabetes

Mediterranean Diet Reduces Heart Attacks and Strokes in Diabetes

Conclusion

A Mediterranean diet reduced heart attacks and strokes in diabetic patients, but also in patients without diabetes. Here I attempted to show what the ingredients of a Mediterranean diet are that lead to such astounding positive effects. There is an emphasis on vegetables and fresh ingredients of food. In addition, olive oil and a lack of processed food are also important. With these wholesome ingredients the lining of the arteries works best. The body reduces cholesterol and lowers blood pressure. The end result is that there are less heart attacks and strokes, and people live longer.

Cutting Out Bad Lifestyle Habits Increases Life Expectancy

A Jan. 8, 2020 study stated that cutting out bad lifestyle habits increases life expectancy. It was a publication in the British Medical Journal by the Harvard T.H. Chan School of Public Health. The senior author of the study was Frank Hu, chair of the Department of Nutrition at Harvard Chan School. The researchers looked at data collected from a large group of males and females that had been accumulated for 34 years. They found that a 50-year-old male or female who did not change their lifestyle habits had another 25.5 years to live for males and another 29 years to live for females.

Five bad lifestyles and life expectancy 

The 5 bad lifestyle habits were smoking, a body mass index above 25.0, excessive alcohol intake, less than 30 minutes of exercise per day and an unhealthy diet.

When people cut out all of those risky lifestyles, 50-year-old men and women had a life expectancy of 37.6 years for men and 43.1 years for women. This was an addition of 12 years of healthy life for men compared to controls who did not change their lifestyles. With regard to women there was an addition of 14 years of life compared to controls.

Diseases that kill prematurely

The research team wanted to know what diseases caused the most reduction in life expectancy when people did not change their bad lifestyle habits. Men and women who cut out all negative lifestyle habits were 82% less likely to die from cardiovascular disease. They also were 65% less likely to die from cancer. Bad lifestyles caused the two major diseases, cardiovascular disease (heart attack and strokes) and cancer, which increased overall mortality. The overall study time was about 30 years. The third major disease that can cost lives is diabetes. In addition, the research team identified chronic diseases as being another potential cause of people dying prematurely.

Additional life expectancy

When life expectancies were broken down according to diseases, the following was noticed.

For men:

When cancer free    When free of heart issues   Without diabetes

6 more years             9 more years                         10 more years

For women:

When cancer free    When free of heart issues   Without diabetes

8 more years            10 more years                       12 more years

Dr. Frank Hu, who chairs the department of nutrition at Harvard T.H. Chan School of Public Health said: ”We found that following a healthy lifestyle can substantially extend the years a person lives disease-free”. Those who do not shed their bad lifestyle habits will come down with one or more of the mentioned diseases and die prematurely. Others who cut out all their bad lifestyle choices live substantially longer.

Diseases caused by poor lifestyle habits

It is important to review the diseases that shorten life expectancy due to having poor lifestyle habits.

Cardiovascular disease

Smoking, lack of regular exercise and poor eating habits result in being overweight or developing obesity. All of these are risks with LDL cholesterol elevation and HDL cholesterol lowering that leads to heart attacks and strokes. Here is a study that shows how life is shortened after a heart attack.

It is clear from this how important it is to give up all of the poor lifestyle habits to avoid this from happening.

Cancer

90% of lung cancers are the result of cigarette smoking.

Heavy drinking can contribute and also lead to cancer of the liver, esophageal cancer, cancer of mouth and throat and cancer of the breasts in women. In addition, cancer of the colon and rectum are also caused by consuming too much alcohol in both sexes.

Diabetes

There are a variety of risk factors causing diabetes. Obesity, a lack of exercise, a bad diet with too much carbohydrates and the aging process are what contributes to the development of type 2 diabetes.

We see again that it is largely lifestyle issues that drive the onset of this disease. People who have developed diabetes need to control their blood sugar very closely to avoid complications of diabetes. This includes making healthier choices.

Otherwise complications of diabetes are diabetic nephropathy, blindness from macular degeneration of the cornea, heart attacks, stroke and diabetic neuropathy. In addition, vascular complications also include artery occlusions in the lower extremities with frequent foot or below knee amputations.

Chronic diseases

Often chronic diseases develop when there is generalized development of inflammation. COPD, chronic kidney disease and arthritis are examples of such conditions. In addition, Alzheimer’s disease, arthritis, asthma, Crohn’s disease, cystic fibrosis and diabetes belong into this category. All of these chronic diseases have in common that cytokines produce inflammation in the body. This keeps the chronic disease going and makes it more difficult to cure. When the person with a chronic disease makes poor lifestyle choices, the inflammation just becomes more chronic.

Smoking is one of the factors that makes chronic inflammation more chronic. Having a body mass index above 25.0 (being overweight) and above 30.0 (obesity) also creates more inflammation in the body. Excessive alcohol intake damages body cells and releases free radicals. These in turn cause inflammation and make the chronic disease more difficult to treat. An unhealthy diet tends to raise the bad LDL cholesterol, introduces pesticides and other chemicals into the system and adds to the chronic inflammation. Finally, a lack of exercise is not contributing to a healthy circulation and lowers the protective HDL cholesterol, paving the way for heart attacks and strokes.

Cutting Out Bad Lifestyle Habits Increases Life Expectancy

Cutting Out Bad Lifestyle Habits Increases Life Expectancy

Conclusion

Bad lifestyle habits are what causes us to get illnesses and die prematurely. Functional medicine and anti-aging medicine are at the frontier of modern medicine. These specialties are teaching us how to stay well and age gracefully. For decades conventional medicine has treated only symptoms, but not the causes of diseases. But this has not changed the mortality rates of heart attacks and cancer. Smoking, a body mass index above 25.0, excessive alcohol intake, exercising less than 30 minutes of exercise per day and an unhealthy diet are causes that make us sick. These bad lifestyle factors cause chronic inflammation in our system. They are the real cause of heart attacks, strokes, cancer and diabetes, the major killer diseases that prevent healthy aging.

Facing bad lifestyle habits

Bad lifestyle habits cause chronic inflammation. T he C-reactive protein blood test can measure the degree of inflammation that is present. A fasting insulin level can detect whether a person is in danger of developing diabetes and improved lifestyle habits can prevent this from happening. Men can add 12 years and women 14 years of healthy life by eliminating bad lifestyle habits. By eliminating chronic inflammation our new life expectancy, which is 79 to 80 years, now can reach 92 to 94 years. It is up to you how healthy you stay and whether or not you age gracefully.

Changes of Metabolism by Inflammation

Dr. James LaValle gave a presentation about changes of metabolism by inflammation in Las Vegas. I listened to this lecture on Dec. 15, 2020. The 27th Annual World Congress on Anti-Aging Medicine in Las Vegas took place from Dec. 13 to 15th, 2019. His original title was: “Innovations in Metabolism and Metaflammation”. This talk was complex and as a result it may not be easy reading. But it shows how various factors can affect our metabolism and our life expectancy.

In the first place he understands “metabolism” as all of the chemical reactions together that make you feel the way you feel today. In the same way metabolism is the chemistry that drives you toward future health. It is equally important to note that disregulation of your metabolism occurs from global metabolic inflammatory signalling. As has been noted he called this “metaflammation” (inflammation affecting your metabolism).

Dr. LaValle said that understanding disruptors of your metabolism can lead to renew your health on a cellular level. The key to achieve this is to remove inflammatory signals.

Factors that accelerate aging and damage your metabolism

It is important to realize that several factors interfere with the normal aging process. Oxidative stress and inflammation are major factors. But hormone disbalance and increased blood sugar values and insulin resistance can also contribute to accelerated aging and damage your metabolism. Certainly, with a disturbance of the immune balance, autoimmune reactions can take place, which also does not help. In addition, pollutants from the environment derange the metabolism due to heavy metals that block important enzymatic reactions. In the minority there are also genetic factors that can interfere with a normal metabolism.

Many of the metabolic changes can lead to chronic inflammation. One source of inflammation can be lipopolysaccharides that stimulate the immune system to start an inflammatory process.

Many conditions are associated with inflammation such as diabetes, obesity, stress, the SAD diet (standard American diet), and liver or kidney damage.

How Metaflammation is developing

Metaflammation can start in the gut with microbiota alterations. The wrong types of bacteria can release lipopolysaccharides, and low grade endotoxemia develops. With obesity inflammatory kinins start circulating in the body. Stress can activate inflammatory substances in the brain and the rest of the body. Major contributors to inflammation in the body come from faulty diets. The Western diet contains too much sugar and refined carbs; it is too high in trans fats and saturated fats. It contains too many artificial additives, preservatives, salt, sweeteners and dyes. And it is too low in nutrients, complex carbs and fiber.

More problems with metaflammation

Kidney and liver illness can contribute to metaflammation. Several diseases come from chronic inflammation, like cardiovascular disease, type 2 diabetes, chronic kidney disease, depression, cancer, dementia, osteoporosis and anemia. Metaflammation alters the methylation patterns, which can slow down your metabolism. Increased blood lipids and chronic inflammation of the blood vessels lead to cardiovascular problems. The liver and kidneys are the major detoxification organs, and their disease leads to more metaflammation. Metaflammation also leads to hormone disbalances, sleep disorders and dysfunction of the immune system. The brain reacts to metaflammation with cognitive dysfunction and mood disorders. Muscle loss (sarcopenia) is another issue, so is osteoporosis. Finally, chronic metaflammation can cause cancer.

Major causes of metaflammation

The three major causes of metaflammation are changes of the gut microbiome, obesity and chronic stress. When the gut bacteria change because of a Western diet, the wrong bacteria release lipopolysaccharides that are absorbed into the blood. The gut barrier is breaking down and a low grade endotoxemia develops. With obesity adipokines, which are inflammatory substances secreted by the fatty tissue, circulate in the blood. Chronic stress activates inflammation in the brain and in the body.

Two major conditions are common with metaflammation: hyperlipidemia (high fat levels in the blood) and hyperglycemia. Both of these conditions change the metabolism and lead to cardiovascular disease (hyperlipidemia) or to type 2 diabetes (hyperglycemia). Both of these metabolic changes lead to one or more of the conditions mentioned above, accelerate the aging process and lead to premature deaths.

Interaction of various organ systems can cause metaflammation

Dr. LaValle stated that it is vital that your hormones stay balanced. With chronic stress cortisol production is high. This causes increased insulin production, reduced thyroid hormone and lowered serotonin and melatonin production in the brain. It also leads to autoimmune antibodies from the immune system and decreased DHEA production in the adrenal glands. In addition, growth hormone production and gonadotropin hormones are slowing down. We already heard that cortisol levels are up. The end result of these hormone changes is that the blood pressure is up and abdominal visceral obesity develops. The brain shows cognitive decline, with memory loss as a result. The bones show osteopenia, osteoporosis and fractures. The muscles shrink due to sarcopenia, frailty is very common. Heart attacks and strokes will develop after many years. The immune system is weak and infections may flare up rapidly. There are also higher death rates with flus.

Other mechanism for pathological changes with hormone disbalances

When Insulin is elevated, inflammatory markers are found in the bloodstream. This elevates the C-reactive protein and leads to damage of the lining of the blood vessels in the body. A combination of insulin resistance and enhanced atherosclerosis increases the danger for heart attacks or strokes significantly.

There is a triangle interaction between the thyroid, the pancreas and the adrenals. Normally the following occurs with normal function. The thyroid increases the metabolism, protein synthesis and the activity of the central nervous system. The pancreas through insulin converts glucose to glycogen in the liver. It also facilitates glucose uptake by body cells. The adrenal hormones are anti-inflammatory, regulate protein, carbohydrate and lipid metabolism and contribute to energy production.

Change of thyroid/pancreas/adrenals triangle when cortisol is elevated

When cortisol is elevated the balance of the thyroid/pancreas/adrenals’ triangle is severely disturbed. Cortisol is high, the T4 to T3 conversion is limited and, in the brain, there is hippocampus atrophy with memory loss and brain fog. The immune system will change with production of inflammatory kinins (IL-6 and TNF alpha). Insulin sensitivity is down, sugar craving up and weight gain develops (central obesity).

Change of thyroid/pancreas/adrenals triangle when the thyroid is depressed

The thyroid activity can be lower because of autoimmune antibodies (Hashimoto’s disease) or because of hypothyroidism developing in older age. This leads to decreased pregnenolone synthesis from cholesterol. As pregnenolone is the precursor for all the steroid hormones, the metabolism slows down profoundly. Mentally there is depressed cognition, memory and mood. The cardiovascular system shows reduced function. In the gut there is reduced gastric motility. The mitochondria, which are tiny energy packages in each cell, are reduced in number, which causes a loss of energy. There is increased oxidative stress, increased lactic acid production and decreased insulin sensitivity.

Cardiovascular disease not just a matter of high cholesterol

Dr. LaValle stressed that a heart attack or stroke is not just a matter of elevated cholesterol. Instead we are looking at a complicated interaction between hypothyroidism, diabetic constellation and inflammatory gut condition. The inflammatory leaky gut syndrome causes autoimmune macrophages and Hashimoto’s disease. The end result is hypothyroidism. The inflammatory kinins (TNF-alpha, IL-6) affect the lining of the blood vessels, which facilitates the development of strokes and heart attacks. You see from this that cardiovascular disease development is a multifactorial process.

Microbiome disruption from drugs

Drugs affecting the intestinal flora are antibiotics, corticosteroids, opioids, antipsychotics, statins, acid suppressing drugs like protein pump inhibitors (PPI’s) and H2-blockers. Other factors are: high sugar intake, pesticides in food, bactericidal chemicals in drinking water, metformin, heavy metals and alcohol overconsumption. Chronic stomach infection with H. pylori, stress and allergies can also interfere with the gut microbiome.

The microbiome disruption affects all facets of metabolism. This means that there can be inhibition of nutrient absorption and this may affect the gut/immune/brain axis. There are negative effects on blood glucose levels and insulin resistance. A disturbance of the sleep pattern may be present. A significant effect on the hormonal balance can occur (thyroid hormones, sex hormones and appetite related hormones). When liver and kidney functions slow down, there is interference of body detoxification.

Dr. LaValle talked more about details regarding the gut-brain-immune pathology. I will not comment on this any further.

Conclusion

Dr. LaValle gave an overview in a lecture regarding changes of metabolism by inflammation. This took place at the 27th Annual World Congress on Anti-Aging Medicine in Las Vegas from Dec. 13 to 15th, 2019.

This article is complex and contains a lot of detail, but there is one simple truth: oxidative stress and inflammation are major factors that influence our health on many parameters and lead to a list of illnesses. They lead to hormone disbalance and increased blood sugars and insulin resistance, which can also contribute to accelerated aging and damage of your metabolism. Dr. LaValle explained how high cortisol from chronic stress can lead to low thyroid hormones and in the brain, there is hippocampus atrophy with memory loss and brain fog. With alterations of the immune system there is production of inflammatory kinins (IL-6 and TNF alpha). Insulin sensitivity is down, sugar craving up and weight gain develops (central obesity). It does not stop there! We put our hope in medications, but the sad truth is that there are

Drugs that change the gut biome

Many drugs that are common also change the gut biome with resulting increased permeability of the gut wall (leaky gut syndrome). This overstimulates the immune system and leads to autoimmune diseases like Crohn’s disease and rheumatoid arthritis. Whenever there is an injury to the gut barrier, the blood brain barrier is following suit. This is how brain disease can develop as a result of a change in the gut biome. Impaired cognition, memory and mood can result from this. Alzheimer’s disease is one of the worst conditions that may be related to a combination of gut inflammation, chronic stress and inflammatory kinins.

How Healthy Is Food From The Supermarket?

I am asking the question here: “how healthy is food from the supermarket?” We tend to assume that food we buy at the supermarket would be safe to eat. Think again, because below I will explain why it is NOT safe.

The “dirty dozen”

You may or may not have heard about the “dirty dozen”. The Environmental Working Group (EWG) is a non-profit organization that monitors fruit and vegetables for insecticide residues. For 2019 they have determined these unhealthy dozen of fruit and vegetables: strawberries, spinach, kale, nectarines, apples, grapes, peaches, cherries, pears, tomatoes, celery, potatoes and peppers (hot and bell peppers). Yes, you counted right, this “dozen” actually consists of 13 items.

When I want to buy any of these fruit, I strictly get fruit and vegetables, which are organic. If this is not available in the regular supermarket, I go to the health food store and buy organic fruit and vegetables there. Local farmers’ markets also offer organically grown produce. Every year the EWG brings out an up-to-date list of the dirty dozen. If an item is not on this list, you can assume that it is safe to eat.

Sugar and too many starches are the next problem

How healthy is food from the supermarket? We said we wanted healthy food. Unfortunately ample consumption of sugar and starchy foods end up as belly fat and also as atheromatous deposits in the arteries. I do not eat bread unless it is 100% rye, but then only 1 or 2 slices occasionally. I do not eat potatoes, rice or pasta. Those who love pasta can eat the pasta-look-alike, called shirataki, which is made from the glucomannan root (also known as konjac root). The carbs here are bound to fiber, which digest a lot slower than regular pasta. So, this means that you are bypassing the section in the supermarket where they sell muffins, donuts etc.

Processed foods

In the center of the supermarket you find all kinds of processed foods. They are usually full of sugar, salt and unhealthy fats (hydrogenated fats). People who eat a lot of processed foods are more prone to get heart attacks, strokes and may even come down with cancer. It is not the kind of food that I want. Instead I like whole foods like organic apples, berries and raw or cooked vegetables.

Fish section

I like salmon, sole, cod, halibut, trout, mussels, shrimp and squid. But I am careful not to load up on the big predator fish like tuna. One has to be careful about methylmercury content in fish. I reviewed fish, mercury contamination and the benefits in this link.

As this link shows, there are low, medium and high methylmercury contaminated fish. The higher the fish is in the predator chain, the higher the methylmercury content. This is of particular concern for pregnant women as mercury is toxic for the fetal brain tissue. But they can consume low mercury fish and shellfish, like mackerel, herring, wild salmon, shrimps or clams. I figure, what’s good for women who are pregnant is good for other people. As a result, I limit my fish meals to the low methylmercury contaminated fish category.

How healthy is food from the supermarket – Meat section

Now your shopping trip becomes problematical. There has been news from the Word Health Organization at the end of 2015 that red meat and red meat products are class 1 carcinogens.

This would mean that you may come down with colorectal cancer, if you consume red meat and red meat products regularly. This is when I stopped eating red meat and red meat products like prosciutto. Unfortunately this warning includes pork, lamb and all sausages as well. In the meantime further research has shown that antibiotics that are fed to beef before they are slaughtered get into the meat and change the human bowel flora when red meat or red meat products are consumed.

Trimethylamine N-oxide (TMAO)

There is a change in bowel flora that causes chemical reactions in the gut with the consumption of beef and eggs. Beef contains carnitine, which can lead to the production of TMAO (trimethylamine N-oxide).

Egg yolk contains choline, which also raises TMAO levels in the blood.

In the following study 113 healthy men and women consumed either a meat diet (beef), white meat diet or protein from non-meat sources. After one month the beef group had triple the amount of TMAO in their blood compared to the other two diets.

Interestingly, when the diets were switched the TMAO levels normalized again in the former beefeaters, when consuming white meat or protein from non-meat sources.

What meat am I shopping for?

I recommend not to eat beef more often than once per week and to eat only grass-fed beef. I eat organic chicken and ground turkey breast meat from health food stores (the turkeys are NOT fed antibiotics). Otherwise I eat seafood, cheese from non-recombinant growth hormone milk. This means that I only buy European import cheese or Canadian cheese. In the US you have to ask for organic milk and organic milk products.

The deep frozen section

I look for deep frozen vegetables, fruit, and fish as well as meats. As vegetables are quickly readied for the freezer, their vitamin content can be higher than that of a vegetable that has spent 8 days in transit from the field to the produce department. The deep frozen section also gives you access to a lot of variety. You’ll be able to enjoy some organic strawberries, even when they are not in season. Read the labels, as some fruit have been packaged with sugar syrup. Look for the varieties, where no sugar has been added. The frozen section also contains some highly processed items: deep-fried foods and dessert selections, which have nothing to do with health, so I avoid them.

Canned foods

Canned foods can be useful, as long as you are dealing with fruit that are canned in their juices and not in sugar syrup. The vegetables are less valuable in vitamins than their deep frozen counterparts. Watch out for varieties, where less salt is added. The label will tell you ”low sodium”. Also pay attention to the cans. Those that are not lined with BPH have a label that emphasizes this. You can avoid this by buying canned food in glass jars, such as tomato sauce.

Cosmetics

You will not have to navigate all the aisles, except for your cleaning products and your cosmetics. These have their own problems: lots of cosmetics contain Parabens. Leave them on the shelf, and be aware that some cleaning products can be hazardous too. Pick environmentally friendly, non-toxic products!

Staples you need

There are some staples, which you will also require: olive oil, some olives, almonds or macadamia nuts (preferably raw). The one cereal product, which is valuable will be coarse rolled oats and some pot barley. Both varieties carry a lot of fibre, which makes them very useful food staples. Avoid the “quick cooking” or “instant” oats. Due to the processing, the carbohydrates are absorbed a lot faster and consequently trigger a higher insulin response.

Drinks

You will wonder about drinks next. Having passed the colas, ginger ales and other sugar pops you may eye the diet drinks. Beware of drinks sweetened with aspartame. There is increasing evidence that phenylalanine (brand names: Aspartame, NutraSweet and Sweet’N Low) is not a “harmless” sweetener. Newer research has shown that it can cause gastroesophageal reflux (=GERD) and migraine headaches. Stevia, a sweetener from a South American plant, does not have harmful effects. Stevia is safe to use, as it does not cause an insulin response. You are best served with mineral water, purified drinking water, herb teas, tea or coffee. Fruit juices do have vitamins and minerals, but they are high in sugar causing an insulin release.

What is in fruit juices?

You would not really eat 3 large apples in one sitting? Probably not! So why insist on drinking 8 oz. of apple juice? You’ll ingest all the sugar and forgo the fibre! You also notice that a lot of fruit juices have been mixed with sugar, water, artificial flavor, some color, and as an apology some vitamin C has been added. They are appearing on the shelves as “a good source of vitamin C”. In reality we are dealing with flavoured, colorful sugar water. Use your own judgement, whether you want to spend your dollars on this selection!

Power bars, snacks

In the aisle adjacent to the pop you will very likely encounter a huge selection of convenience and snack foods. They have several things in common: you have met them on TV, some will be high in starches and fat (chips), others will be high in starches, sugar, and fat (cookies, donuts, cream pastries), and we are dealing with trans fats. Do take time to read the listed ingredients, and then decide, whether you and those who eat in your household deserve nutritional garbage. 

How Healthy Is Food From The Supermarket?

How Healthy Is Food From The Supermarket?

Conclusion

We have now completed our round trip in the supermarket. You may still be in mild shock, noticing that “healthy” foods are not the general rule on the shelves. When we buy vegetables and fruit we have to be aware of the “dirty dozen”, which is contaminated with insecticides. We will not buy anything on that list, but buy instead the organic version. You may have to go to the health food store to get these items. Red meat and red meat products produce carcinogens in the human gut. It seems to stem from antibiotics that are used in beef farms and chicken farms. With chicken I buy organic chicken. With beef you need to be more careful and reduce the consumption to once per week and eat only grass-fed beef.

It is tricky to buy healthy food from the supermarket

Much of the bakery section is useless. It consists of empty starch that is digested into sugar and leads to an insulin response. I avoid the processed food section, which contains unhealthy ingredients. Fish is great as long as it does not have too much methylmercury in it. Deep frozen foods may be useful.

Shopping for healthy foods from the supermarket has become more complicated than it was in the past. I only select healthy items and supplement the rest from the health food store. This way I get what I need and avoid the pitfalls of merchandise, which is not beneficial.

Fasting Mimicking Diet For 5 Days Every Month

In December 2017 I heard Dr. Longo speak at a medical conference in Las Vegas. He suggested the use of the fasting mimicking diet for 5 days every month. I am getting into the age group where a little help from nature would not harm (I am 74 years old). I started immediately in December 2017 to do a fasting mimicking diet (FMD) for 5 days.

Effects of fasting mimicking diet

In the beginning you just notice that you are not as hungry as you thought you would be, because you do take in three mini meals of about 200 calories each, which curbs your appetite. It is also important to consume enough liquids. Please note: liquids! Not liquor! Wine, beer or any alcoholic drinks are not part of the diet. You can drink water, but, this may get boring, and you can take water with lemon, herbal teas, black tea and coffee, as long as you stay away from sugar-laced drinks.

How the FMD works

Your total calorie intake will amount to no more than 600 calories per day for the 5 days where you do the fasting mimicking diet. Your body mass index (BMI) decreases between 0.1 and 0.4 per day to a total of 0.5 to 0.9 for the 5 days. This does not seem much, but if it is accumulating every month, a person who is obese now could have a normal weight within one year. The first day of this fast may present some challenges. I found that in the afternoon I felt hungry. What helped was a hot drink( tea, coffee, clear broth). Day two was better, and from day three it has become a routine. There are  no ferocious hunger pangs, no headaches or feelings of weakness or tiredness. I am always surprised that my energy level is improving when I do the fasting mimicking diet for 5 days every month.Dr. Longo suggests not to exercise during the fast. It is obvious that this time is not suitable for half- marathons or taxing hikes, but I found that thirty minutes of aerobics and thirty minutes of weight training felt good. Listen to your body! If you feel lightheaded at any time, stop! The emphasis is on “moderate”.

Dr. Longo noticed the following findings in a mouse model as well as on humans. I summarized this before in a previous blog:

Specific results when on the fasting mimicking diet for 5 days every month

  • Obesity diminishes, because of the weight loss effect due to missing calories.
  • Diabetes: insulin resistance becomes lower and blood sugar levels drop.
  • High blood pressure reduced: many patients were able to reduce their medications or discontinue them
  • Pain conditions improve as all kinds of pain disappears, an effect for which there is no explanation at this point
  • Autoimmune diseases like MS and rheumatoid arthritis improve, likely because of the effect of increased stem cell circulation
  • Prevention of heart attacks and strokes because of reduction of LDL, triglycerides and CRP
  • Cancer cure rates improve by protecting normal cells, the bone marrow and stimulating the immune cells
  • Longevity improved in mice with a 3-fold increase of their life span. Telomere length in humans was increased. Increased stem cells will find defective areas that need repair. This effect leads to less disease in older age.

Meal samples of fasting mimicking diet

Dr. Longo developed a kit containing all pre-packaged foods for 5 days under the name “ProLon Fasting Mimicking Diet”. The package is not larger than a shoebox, and the diet is plant-based, has some nutrition bars, drinks as well as freeze-dried soups. You can argue about the nutritional value, as it has an average rating of 3.5 out of 5. It also comes in at a hefty price of 300.00 USD. In reality it is a matter of calorie-math to consume very little food. There are plenty of tables available on the Internet that tell you the nutritional value of foods, and it does not take much effort to compose your own menu.

Here is a fairly typical list of foods

Breakfast: A typical breakfast consists of 2 slices of rye crisp bread (Wasa or Ryvita) with a bit of almond butter on it, a cup of coffee and either black or with stevia and milk.

Lunch: 8 oz. of tomato soup and coffee or tea.

Dinner: A tossed salad with organic bell peppers, ½ tomato, and two thin slices of avocado, vinegar and 1 tablespoon of olive oil.

Here is an alternative meal sample:

Breakfast: Eat a nutrition bar that is based on nuts. It should not be more than 250 calories. Alternatively make your own! Have tea or coffee.

Lunch: 8 oz. of homemade vegetable soup without the addition of pasta or beans.

Dinner: Miso soup and 4 rice crackers, alternatively a small tossed salad with olive oil and vinegar.

Results of fasting mimicking diet for 5 days every month

Here are typical results that I found over several months. I am using body composition scales every day to measure my weight, body fat percentage, visceral fat percentage, muscle percentage, calories burnt and the BMI.

One month the BMI went from 21.9 to 21.1 during a 5-day FMD. Another month the BMI experienced a reduction from 21.7 to 21. 2. Here is a list of the some of the 5-day losses of my BMI on a couple of occasions: 0.8, 0.4, 0.9, 0.7, 0.6, 0.5, 0.7 and so on.

It is important that you are not going on an eating binge after those five days. The FMD conditioned your body to be content with very small amounts of food. Enjoy your food, but stick to moderate portions.

Discussion of fasting mimicking diet for 5 days every month

An intermittent fasting mimicking diet was shown to have a diversified positive health effect in both animal models and humans. For instance, inflammatory bowel disease improves on FMD by improving the bowel microbiota and by promoting the intestinal regeneration.

Intermittent fasting, as this article shows, can prevent age-associated diseases.

This article suggests that T-killer cells that attack cancers are promoted by the intermittent fasting mimicking diet.

A FMD in type 1 diabetic patients has been shown to restore insulin generation in islets of the pancreas of these patients. The result was an improvement of their type 1 diabetes.

More research data on fasting mimicking diet

A clinical trial with 100 subjects was undertaken by Dr. Longo and his research team. He measured markers after 3 cycles of a fasting mimicking diet for 5 days every month. They found that the FMD reduced aging markers, improved diabetes and reduced susceptibility for cancer and cardiovascular disease. In another publication Dr. Longo and co-authors describe how autoimmune diseases can be improved by the use the fasting mimicking diet for 5 days every month.

Another publication by Dr. Longo describes that “age-related disorders including diabetes, cardiovascular disease, cancers and neurological disorders such as Alzheimer’s disease, Parkinson’s disease and stroke” can be prevented by fasting mimicking diet for 5 days every month.

Even cancer prevention and cancer treatment can be helped by the fasting mimicking diet.  The FMD makes chemotherapy more tolerable.

Conclusion

I have shown that with the fasting mimicking diet (FMD) done for 5 days in every month you can lower your body mass index (BMI) by 0.4 to 0.9 units. On the long-term this helps you to keep your BMI stable and in the 21.0 to 22.0 range. Dr. Longo has researched the effect of the FMD in both mice and humans. He found that you age better with less age-related diseases. In addition, inflammatory bowel disease, autoimmune diseases like MS, rheumatoid arthritis and type-1 diabetes improve. Cancer patients who need chemotherapy tolerate it better. Their immune system also produces more killer T cells that destroy cancer cells. The FMD prevents heart attacks, strokes and cancer. Dr. Longo also has shown that there is stimulation of stem cell production and telomeres are increasing in length. Telomeres are important for longevity, which allows you to age healthier with less disease.
