Ultraprocessed Food Leads to Premature Aging

By Ray Schilling | Cancer, Cardiovascular disease, cholesterol, diet, food, meat, Mortality, Nutrition, Obesity, Processed food, processed meat

What are ultraprocessed foods?

The NOVA Food Classification System explains what ultraprocessed foods (UPFs) are and what other ones are not. Examples of ultraprocessed foods are: fatty, sweet, savory or salty packaged snacks, pre-prepared poultry and fish ‘nuggets’ and ‘sticks.’ Others are cola, soda and other carbonated soft drinks, pastries, cakes and cake mix. Generally speaking, the food processors add too much salt, sugar and saturated fat. They often also add food preservatives, coloring, and flavor enhancers.

What do ultraprocessed foods cause?

Sugary beverages lead to blood sugar peaks and insulin surges. This in turn can cause type 2 diabetes later on. Melanie Murphy Richter, MS, RDN, a registered dietitian nutritionist said that “overly salty snacks like chips, crackers, and instant noodles, and other UPFs with trans fats and hydrogenated oils all should ideally be avoided”. Read labels before you buy any food product. Hydrogenated oils and trans fats are increasing LDL cholesterol leading to premature hardening of the arteries. This can cause strokes and heart attacks.

Hot dogs, sausages, and deli meats contain nitrates and nitrites as preservatives. This can form carcinogenic compounds like nitrosamines during cooking or metabolism. The World Health Organization (WHO) has classified processed meats to contain Group 1 carcinogens. These processed meats also contain high amounts of sodium and saturated fats. This causes high blood pressure and cardiovascular disease.

Telomere length reduced by ultraprocessed foods

Another study regarding consumption of ultraprocessed foods came out in 2020. There were 886 participants aged 57–91. Researchers measured telomere length in saliva samples. Subjects with the highest UPF consumption had almost twice the odds of having short telomeres in comparison to those with the lowest UPF consumption. Patients with shorter telomeres were much more prone to chronic diseases like cancer and cardiovascular disease. The overall death rate was much higher in patients with shorter telomeres. This confirms what another study also found.

Ultraprocessed foods are causing obesity and weight gain

Another study found that ultraprocessed foods caused weight gain and obesity. The authors of this study pointed out that US residents eat up to 70% of the total calorie input as UPFs. They reviewed the literature and found that UPF consumption raises the risk of obesity. Also, chronic conditions like cancer, strokes, heart attacks, type 2 diabetes and depression are directly linked to UPF consumption. Because of the development of these chronic health conditions the life expectancy is about 10% shorter than for those who don’t consume UPFs.

Ultraprocessed Food Leads to Premature Aging

Conclusion

Over the past several decades food companies produced more and more ultraprocessed foods (UPFs). You see them on grocery store shelves. They contain high amounts of sugar, saturated fat and salt. This can cause cardiovascular disease. Added food preservatives, coloring, and flavor enhancers are also of concern as they may lead to UPF food addiction. Obesity, cancer, heart attacks and strokes are often the final result of UPF overconsumption. Another publication that I reviewed showed that consumption of UPF leads to shorter telomeres in all body cells. We know from other publications that short telomeres cause chronic diseases and premature deaths because of organ failures. The bottom line is that you want to reduce your UPF food intake and increase your whole food intake. This will strengthen your immune system, prevent heart attacks, strokes and cancer. Your telomeres will stay long and your life expectancy increases by about 6 years.

Ozempic and Wegovy can Lead to Blindness in one Eye

By Ray Schilling | fasting mimicking diet, Nutrition, Obesity, Weight loss

Shocking medical news found that Ozempic and Wegovy can lead to blindness in one eye. Ozempic was approved by the FDA for treatment of diabetes. Wegovy, which is the same drug, got FDA approval for treatment of obesity. The pharmacological name of the drug is semaglutide. Both brand names of the drug are very popular, but they have side effects.

List of side effects of Ozempic and Wegovy

Physicians noted the following side effects of semaglutide. Nausea and vomiting, diarrhea, constipation, gas and bloating, stomach pain, fatigue, burping and changes to your face (Ozempic face). In addition, headache, rebound weight gain, low blood glucose, vivid dreams, hair loss, pancreatitis, gallbladder disease, kidney damage. Finally, there are also allergic reactions, thyroid tumors and stomach paralysis (gastroparesis) that are listed as side effects.

Rare side-effects of Ozempic and Wegovy

There is one side effect of Ozempic or Wegovy, namely a higher risk of developing a rare form of blindness. This has the name “Nonarteritic Anterior Ischemic Optic Neuropathy” or “NAION”. Only 10 out of 100,000 people in the general population may experience it. But patients who take Ozempic or Wegovy get this more often. People who took Ozempic for diabetes were 4-times more likely to develop blindness in one eye from NAION. And people who took Wegovy for obesity were 7-times more likely to get blind on one eye from NAION.

Alternative measures to treat diabetes and obesity

The question is whether you really need Ozempic or Wegovy to achieve control of your blood sugars or control of your body weight.“A crossover study showed that a fasting-mimicking diet is benefitting cardiovascular health. This new study was done by Dr. Valter Longo et al. from the University of Southern California. It compared the effect of two diets. They were the fasting-mimicking diet versus an unrestricted diet. In other studies Dr. Longo compared the fasting-mimicking diet (FMD) with a Mediterranean diet. He said: “The significance is that fasting-mimicking diet cycles were able to decrease fat mass without reducing muscle mass and without requiring changes in the subjects’ preferred diet for 25 days a month. In contrast, the everyday Mediterranean diet required a change in everyday dietary habits and had an association of 5 pounds loss of muscle.” It makes sense to use the FMD instead of the potentially dangerous Ozempic or Wegovy.

Effects of the fasting mimicking diet

The fasting mimicking diet consists of 5 days of a calorie reduced diet (500 to 600 calories per day) once a month. This helps you to reduce your weight and maintain it subsequently. Weight loss and control of diabetes are the main effects.

Ozempic and Wegovy can Lead to Blindness in one Eye

Conclusion

A rare complication of the popular medications Ozempic and Wegovy is the development of a rare form of blindness. This has the name “Nonarteritic Anterior Ischemic Optic Neuropathy” or “NAION”. Only 10 out of 100,000 people in the general population may experience it. But patients who take Ozempic or Wegovy get this more often, namely 4-times more often with Ozempic and 7-fold more often with Wegovy. On the other hand, weight loss can be achieved with a simple fasting mimicking diet, where you consume 500-600 calories for 5 days in a row per month. The rest of the month (25 days) you take in a normal diet. This helps you to slowly shed weight and maintain your reduced weight.

Fasting mimicking diet much safer than Ozempic or Wegovy

In my opinion the fasting mimicking diet is much safer than taking Ozempic or Wegovy. Current mainstream medicine claims that the likelihood of developing one-sided blindness from NAION is “negligible”. However, I prefer the FMD over Ozempic or Wegovy. It is important to me to maintain vision in both of my eyes.

Metabolism Can Vary in People

By Ray Schilling | Cancer, Cardiovascular disease, cholesterol, Diabetes, diet, exercise, fasting mimicking diet, Fitness, green tea, Hormones, lifestyle, mitochondria, Obesity, Smoking, Weight loss

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

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.

About Aging and a Prolonged Life

By Ray Schilling | alcohol, andropause, Cancer, Cardiovascular disease, Diabetes, diet, exercise, fasting mimicking diet, Fitness, heart attack, High Blood Pressure, Hormones, Menopause, Mortality, Obesity, Prevention, sleep

The topic “about aging and a prolonged life” is always popular with people. CNN recently discussed this topic with the Nobel prize winner and molecular biologist, Professor Venki Ramakrishnan. He shared the 2009 Nobel Prize in Chemistry with Thomas A. Steitz and Ada Yonath for research on the structure and function of ribosomes. Ribosomes are sub particles in the cell responsible for making proteins. In the following I will summarize this interview.

What is aging?

150 years ago, people lived only about to 40 years. Today we can live up to 84 years in most countries. It is because medicine has learnt a lot about the reasons why diseases occur and how they can be cured. Physicians have a number of antibiotics available for those who suffer infections. Heart bypass surgeries and stents can prolong a person’s life when there is hardening of the coronary arteries.

Aging processes

The following aging processes occur all our lives:

DNA breaks happen in our cells, but repair mechanisms are in place that deal with this. With older age repair mechanisms are more sluggish.
Faulty proteins form inside cells, however, we have mechanisms to take care of that.
Chemical damage to molecules in our cells accumulates. The cells can only partially eliminate these.
Hormone disbalances occur during menopause and andropause. But anti-aging physicians can correct this by doing hormone tests and ordering bioidentical hormone supplements.
There are limits of what anti-aging medicine can do: osteoarthritis affects our joints; our muscles are aging and with it our heart muscle. Degenerative neurological diseases like multiple sclerosis, Parkinson’s disease and dementia occur frequently as we get older with no effective therapies.
The immune system weakens with age. To a certain extend vitamin D3 and other supplements can strengthen it, but only to a certain extent.

Systems working together in our body

Dr. Ramakrishnan said that our bodies work like cities. In it are various systems that need to work together to keep us alive. If a major system fails, we die. Some of the essential organ systems are the heart, the brain, kidneys, our gut, the lungs, the bone marrow and all our hormone glands. If one of these organs breaks down, we are in trouble. If an organ donor is not available, we perish. But even when everything is working together well, we are limited reaching a maximal lifespan of about 120 years. This has to do with limits of our cell metabolism and the aging processes mentioned above. Science has not found a way to prolong our maximal lifespan and likely will not find one soon. But there are various lifestyles that can prolong life as I mentioned here before.

Genetic effect on our lifespan

CNN asked Dr. Ramakrishnan what genetic effects there are that would transmit longevity from a parent who lived until 95 or older to a child’s lifespan. He answered the following: “There is a correlation between the ages of parents and their children, but it’s not perfect. A study of 2,700 Danish twins showed that heritability — how much of our longevity is due to our genes — only accounted for about 25% of lifespan. Still, researchers have found that mutation in just a single gene can double the lifespan of a certain type of worm. Clearly there’s a genetic component, but the effects and implications are complex.”

Relationship between cancer and aging

The same genes are involved for the growth of the body at a young age, and the older person who comes down with cancer. In old age the same genes can cause cancer and dementia. Dr. Ramakrishnan said: “Our risk of cancer increases with age because we accumulate defects in our DNA and genome, which sometimes cause gene malfunctions that lead to cancer. But many of our cellular repair systems that seem to be designed to avoid cancer early in life also cause aging later.”

Apoptosis (programmed cell death) and senescent cells

The body has two mechanisms in place that counter the danger of developing cancer cells. Dr. Ramakrishnan explained: “For example, cells can sense breaks in our DNA that might allow chromosomes to join in an abnormal way, which could lead to cancer. To prevent that joining, a cell will either kill itself or enter a state called senescence, where it can no longer divide. From the perspective of an organism like us, which has trillions of cells, this makes sense. Even if millions of cells are destroyed this way, these actions protect the whole organism. But the buildup of senescent cells is one of the ways we age.”

Lifestyle changes that help you live longer

Dr. Ramakrishnan said that our grandmothers knew what a healthy lifestyle was. The following is a list of what science now confirms adds years to your life:

Don’t be gluttonous. Eating a variety of healthy foods in moderation can prevent the health risks of obesity.
Get exercise: this helps us regenerate new mitochondria, which are the powerhouses of our cells providing energy.
Avoid stress, which creates hormonal effects that change our metabolism and can accelerate aging.

More life prolonging points:

Get enough sleep. This allows our bodies to do molecular-level repair.
One of the newer findings is Dr. Longo’s fasting mimicking diet. Do a semi-fast once a month for 5 days with 500 to 600 calories per day. This helps you to shed 0.5 to 0.7 units of body mass index. It also stimulates your immune cells, your stem cells and elongates your telomeres. Long telomeres make you live longer.
Replacing missing hormones with the help of an anti-aging physician will add about 10 years to your life. I mentioned this earlier.

A few more points about longevity research

Dr. Ramakrishnan said: “Already the top 10% of income earners in both the US and the UK live more than a decade longer than the bottom 10%. If you look at health span — the number of years of healthy life — that disparity is even greater. Poorer people are living shorter, less healthy lives.” He said further about the concept of “immortality”: “I think this quest for immortality is a mirage. One hundred and fifty years ago, you could expect to live until about 40. Today, life expectancy is about 80, which, as author Steven Johnson has said, is almost like adding a whole extra life. But we’re still obsessed about dying. I think if we lived to be 150, we’d be fretting about why we’re not living to 200 or 300. It’s never-ending.”

About Aging and a Prolonged Life

Conclusion

CNN discussed the quest for longevity with Nobel prize winning Dr. Ramakrishnan. He pointed out that the aging process is due to a number of factors that work together. There are DNA breaks, faulty proteins, chemical damage to molecules, hormone disbalances and degenerative changes. We need to watch that we do not overeat, get regular exercise and eat a variety of healthy foods. In addition, we need to avoid stress, get enough sleep and replace missing hormones with bioidentical hormones. A newer boost to your health is the fasting-mimicking diet (FMD) from Dr. Valter Longo that helps you keep your weight in the lower body mass index range. Dr. Longo showed in animal experiments and with humans that the FMD elongates telomeres, which directly prolongs life.

Apply what helps your longevity

While it is far-fetched to believe that we now have a ticket to live for 120 years or longer, it is more important to know that we can do our part to spend our golden years in health and wellness.

Plant-Based Meat Alternatives are Healthier

By Ray Schilling | Cancer, Cardiovascular disease, diet, food, Health, Nutrition, Obesity, Weight loss

A recent study showed that plant-based meat alternatives are healthier than the original meat dishes. This spread into various health websites on the Internet. One example is this one.

Some statistics about plant-based meat alternatives

Plant-based meat alternatives came to the market in the 1960’s. At that time, they consisted mainly of soy. Later textured vegetable protein joined soy products. Today they consist of pea protein, soy, potato, oils, various binders and flavorings to mimic the texture and flavor of meat.

The global plant-based meat market was about 5 billion USD last year. It is projected to increase by 19% from 2022 to 2030. The plant-based dairy alternatives market totaled 11 billion in 2020. The estimate is that this will grow to 32 billion in 2031.

How healthy are plant-based substitutes?

In the center of this discussion is the publication of Christopher J. Bryant from the Bath University in England. This publication reviewed 43 studies regarding plant-based substitutes regarding healthiness and environmental sustainability. In the following I am discussing the findings, particularly about health benefit of plant-based foods versus meat-based foods.

Problems with our current food consumption

There are several problems with human diseases that are transmitted from wildlife. HIV arouse from hunting of non-human primates. Rabies was transmitted in South America by vampire bats from cattle to humans. Early cases of severe acute respiratory syndrome (SARS) came from contact with wild life. Finally, bats transmitted the SARS coronavirus-like virus from wild animals and live animal markets to humans. Subsequently human to human transmission caused the spread of Covid all around the world as a pandemic.

Use of antibiotics in feedlots

In order to control diseases in closely kept animal feedlots farmers feed the livestock antibiotics. This helps to contain infections, but it also poses a grave problem to humans as antibiotics become more and more resistant. Superbugs developed this way. 18% of meat imported from China was contaminated with Salmonella. 88% of those exposed to contaminated meat were resistant to at least one antibiotic. But 58% were resistant to multiple antibiotics.

A Harvard study from Boston showed in 2020 that red meat and processed red meat consumption caused 15% more heart attacks compared to those who substituted the protein source with plant-based foods. The same study also noted that the heart attack rates were about 15% less for subjects who substituted meat with plant products in comparison to meat eaters.

Other results of the study

Several of the reviewed studies compared the nutritional profile of plant-based meat with the animal-based counterparts. Plant-based meat was significantly lower in saturated fat, and protein. However, they were significantly higher in fibre and salt. 40% of meat products were classified as ‘less healthy’. In comparison to that investigators assessed that only 14% of plant-based meat was ‘less healthy’. When saturated fat, sodium, sugar, and overall calorie content were tabulated, plant-based meat products compared favorably to meat. But salt content was often too high in plant-derived foods.

Plant-based burgers were much healthier than conventional beef-burgers, as they contained no cholesterol, less trans-fatty acids and less saturated fat. Vegetable-based food that contains pea protein is particularly valuable with regard to a high protein content.

Criticism of plant-based meat alternatives

At the present time many plant-based meat products have too much sugar and salt in it, but lack iron and vitamin B12. Various authors suggested that the food industry should add iron and vitamin B12 to their products and reduce the sugar and salt content.

Muscle synthesis

Mycoprotein is the active biochemical that builds up the protein of the muscle mass in man. Non-animal-derived dietary protein contains ample amounts of mycoprotein according to this publication. These authors investigated the ingestion of mycoprotein in a dose-response manner. They also measured insulin levels for 4 hours after ingestion of plant-derived mycoprotein. Insulin levels remain higher than normal for a sustained period.

Weight loss

A 2017 study showed that 40 grams of mycoprotein, which is the equivalent of 18 grams of protein was sufficient to lead to a robust muscle synthetic response. 60 g of mycoprotein (27 g protein) provided an optimal response regarding muscle synthesis. Gram for gram milk protein and mycoprotein were equivalent in amino acid bioavailability. Several studies examined weight loss following mycoprotein meals. One study found in overweight patients that chicken protein consumption was higher in comparison to consumption of plant mycoprotein. The mycoprotein consuming group chose to eat 10% less calories than the chicken control group.

Greenhouse gas emissions and other factors

The publication cited above also included a lot of findings regarding how plant-derived food saves greenhouse gas emissions and other facts. For instance, the pork supply chain requires 3.3-times more fertilizer and 1.6-times more pesticides than the production of plant-derived food. What this means is that plant-derived foods are more environmentally sustainable than animal products.

Plant-Based Meat Alternatives are Healthier

Conclusion

Plant-derived foods have improved in the past few decades. Pea-derived plant products are now equivalent in terms of protein content to milk and meat. By eating more plant-derived food people consume less meat, which helps the environment, but also benefits the person who eats it. We know that with the consumption of a certain amount of plant-derived food less people develop cardiovascular disease, diabetes and cancer. 40 grams of mycoprotein, which is the equivalent of 18 grams of protein was sufficient to lead to a robust muscle synthetic response.

Consumer beware

It is important to realize that not all is well with the list of “fake meat” and other highly processed plant-based products. Consumers must read the list of ingredients. If a product contains a laundry list of ingredients that not even an adult can pronounce and understand, it is very likely a highly processed food product that only pretends to be good for you. Should the sodium content be too high, steer away from it. High sugar content means that you put it back in the shelf. All in all, eating more plant-derived foods makes you healthier and improves the environment at the same time. But it is up to us to be discriminating colourful advertising from a nutritionally sound product.

Adolescents’ Lifestyles Are Linked to Faster Aging in Adulthood

By Ray Schilling | diet, fasting mimicking diet, Mental Health, mitochondria, Mortality, Obesity, Smoking, Vitamins and supplements

A longitudinal study found that adolescents’ lifestyles are linked to faster aging in adulthood. The study started with a baseline examination in a group of adolescents around the age of 15. 30 years later doctors examined the same individuals again. The researchers found that smokers, obese people and people with untreated emotional problems were aging faster than controls who did not have these problems. CNN discussed this study as well. A fourth condition, asthma was also included in the study. Indeed, adolescents who suffered from asthma in their mid-teens were not more biologically aged at age 45 when compared to controls who never had asthma. The authors concluded that treated asthma did not prematurely age a person. However, lifestyle habits like smoking, excessive weight and untreated mental illness contributed to accelerated aging.

Does having a healthy lifestyle lower your risk of developing medical conditions and diseases?

It must be remembered that anti-aging medicine is watching out for new treatments that can prolong life. However, this is not just one “breakthrough”, but rather a number of factors that in combination lead to longevity.

Resveratrol

Resveratrol, the supplement from red grape skin can stimulate your mitochondria metabolism. Exercise more and regularly as this will also stimulate your mitochondria to multiply similar to the effects of PQQ, a supplement. I take 500 mg of resveratrol concentrate once daily.

Exercise regularly

The first thing to remember is that regular exercise will prevent about 50% of chronic diseases (diabetes, heart failure, arthritis). Consequently, this prolongs life: Lack of exercise is a major cause of chronic diseases.

Replacing missing hormones with bioidentical hormones

When you enter menopause or andropause replace missing hormones with bioidentical hormones. This will add 10–15 years of good life. This information comes from the anti-aging medicine circles and European studies of women on bioidentical hormone replacement. Here is a more conservative opinion from a US review: Counseling Postmenopausal Women about Bioidentical Hormones: Ten Discussion Points for Practicing Physicians.

Abandon sugar, starchy foods

Starchy foods (potatoes, pasta, rice, pastries and bread) and processed food accelerate aging. Avoid these foods for a healthier heart – Harvard Health. Many studies have confirmed that a Mediterranean diet is anti-inflammatory and prevents premature aging.

Are you deficient in human growth hormone?

Find out whether you are deficient in human growth hormone or not by taking an IGF-1 blood test. Dr. Hertoghe, an endocrinologist from Belgium said at various anti-aging conferences that HGH by itself prolongs life by about 15 to 20 years or more. I am deficient in HGH and I am injecting HGH myself regularly. My anti-aging physician orders my IGF-1 level three to four times per year to monitor the right dosage of HGH replacement. But it is crucial that the physician supervise the patient. This involves giving the patient only minimal amounts of HGH, which keeps IGF-1 levels in the high normal range. This is also re-emphasized in this review: Growth Hormone and Aging: Updated Review. When you overdose HGH, you lose all of the beneficial effects that HGH replacement brings.

Fasting mimicking diet (FMD)

Fasting for Longevity: 9 Questions for Dr. Valter D. Longo. When you consume only 500 to 600 calories daily for 5 days out of every month you are stimulating your telomeres (the caps on your chromosomes) to grow a little bit longer. Longer telomeres translate into longer life expectancy. In addition, your stem cells anywhere in your body also undergo stimulation. Here is more information: fasting mimicking diet for 5 days every month.

Lifestyle factors

It is best not to smoke. Keep your body mass index in the 21.0 to 22.0 range. Get enough sleep (7–8 hours every night). Use a form of relaxing exercise (yoga, self-hypnosis, meditation, Tai-Chi). This will keep the stress hormone cortisol under control; if it is constantly high from ongoing stress, it leads to premature deaths. The Science of STRESS – SLMA

Take key vitamins and minerals

When you take key vitamins and minerals every day you can add another 5 to 10 years of disease-free life to your life expectancy. Ray Schilling’s answer to Is taking vitamin supplements helpful or quackery?

All of these factors taken together help you to not age prematurely. A healthy lifestyle elongates your telomeres, which prolongs your life without diseases. It also prevents heart attacks and strokes, which again prolongs your life. And a healthy lifestyle prevents Alzheimer’s disease, so you can turn old and not have to worry about memory loss. I cannot overemphasize how important a healthy lifestyle is!

Conclusion

As summarized above, a recent study going on for about 30 years showed that premature biological aging occurs in adolescents who smoked, were obese or had untreated mental illness. On the other hand, treated asthmatics did not show this biological aging effect. I summarized what factors contribute to slowing down aging. It is a combination of proper diet, regular exercise, hormone replacement as you age and taking some supplements. One key to slower aging is to be aware of how important a healthy lifestyle is for you.

What can Happen to Your Body Over Months of Isolation

By Ray Schilling | Cardiovascular disease, Circadian rhythm, diet, exercise, fasting mimicking diet, Fitness, heart attack, melatonin, Obesity, Processed food, sleep, Stroke, vaccinations

A recent article by CNN describes what can happen to your body over months of isolation at home. The article is rather negative showing all the possible things that can go wrong. I have been isolated as well since March 2020. I handle the isolation differently than described in the article. I will comment to each point what can be done differently to avoid the complications mentioned.

Muscle loss

The CNN article makes the point that inactivity can make you lose muscle bulk within only one week. A lack of exercise weakens your muscle strength. And muscle strength has been associated with longevity.

My comment:

I do a brisk walk of 5 to 7 kilometers daily. This maintains my muscle bulk. But I have a treadmill in the basement and a couple of weights that I can use, if it rains outside.

There is a danger that heart and lungs get weaker

You need to raise your heart rate and you also need to perfuse your lungs through exercise. Many people do not like exercise. They sit in front of the TV for hours or they surf the net on the computer. Even just reading a book does not give you enough exercise to get your heart rate up and increase your lung perfusion.

My comment:

A brisk walk with proper distancing gives you fresh air, exercises your muscles, your heart and your lungs. It maintains your cardiovascular fitness.

Weight gain

Being home all the time allows you to look into the fridge more often and eat snacks that are processed. People tend to eat more often than 3 times a day. The end result is that you gain weight. In the beginning of the epidemic people stocked up on non-perishable foods. Often they contain more sugar and carbohydrates. Consuming these foods leads to weight gain. Wearing masks, frequent hand washing, isolation practices and change of normal routines makes people get stressed. Stress leads to overeating and weight gain.

My comment:

In the last 6 months that I did home isolation my body mass index (BMI) stayed in the 21.0 to 22.0 range. I ate three meals a day. I avoided processed foods as they are overloaded with sugar, salt and refined carbs. Once a month I do a 5-day fasting mimicking diet according to Dr. Longo. This ensures that my BMI stays within the range I indicated. Otherwise I eat a Mediterranean diet, which is anti-inflammatory.

Your posture could suffer

When you are seated in front of the computer or the TV you tend to engage in poor postures. This can lead to strains of your back, neck, shoulders and hips. Staring at the computer screen or the TV can also give you eye strain.

My comment:

The key is movement, such as getting up and walking around; doing other activities like lawn mowing, weed eating or doing dishes. This interrupts any longer stretch of bad posture.

Your sleep quality can suffer

The more exposure to sunlight during the day you get, the more vitamin D you produce in the skin. Some people lack the necessary enzymes in the skin to convert cholesterol into vitamin D. But exposure to sunlight also helps to reinforce your diurnal hormone rhythm. This is also called circadian rhythm. Avoid blue lights (TV, computer, iPhones etc.) in the evening before bedtime as this can interfere with a deep sleep later. Also go to bed early enough (between 10 and 11 PM) to allow your circadian rhythm to take over.

My comment:

Some people (above the age of 60) benefit from 3 mg of melatonin at bedtime. After the age of 60 people no longer produce enough melatonin in the pineal gland. If I wake up in the middle of the night, I take another 3 mg of melatonin prior to 3AM. Caution: after 3 AM melatonin can give you a bit of a hangover in the morning.

Your brain can slow down

The brain needs nutrition and exercise. Exercise can eliminate certain amino acid by-products that otherwise turn into neurotoxins. With exercise you even prevent neurotoxins to enter the brain.

My comment:

I find that I must at least do a brisk walk of 4 kilometers a day. It prevents back pain, helps me sleep better and keeps my mind clear. But as mentioned earlier I prefer doing a brisk walk for 5 to 7 kilometers a day. In the past (prior to March 2020 when the Covid-19 pandemic started) I went to the gym every day. When it finally reopened, they had one Covid-19 case at the gym. I decided that it is too dangerous to go back to the gym until a safe Covid-19 vaccine is available in the summer of 2021. I feel the same way about flying. It is not worth the risk. I can just stay local and do my own program. The pleasure of traveling can wait until the summer of next year.

What can Happen to Your Body Over Months of Isolation

Conclusion

A recent CNN article described the dangers of passively staying in home isolation. I felt that this article was on the negative side. I found that by including a regular brisk walking program into my daily lifestyle the day got more structured. I felt I had more energy and I had no aches or pains. If I spent too much time watching TV or spending in front of the computer, I developed back aches and felt sluggish. I incorporated a 5-day fasting mimicking diet according to Dr. Longo once per month into my regular Mediterranean diet. This allowed me to keep my body mass index in the 21.0- 22.0 range. Doing what I described above I could continue to hold my weight, have energy and stay pain free for many more months. But when the Covid-19 vaccine arrives in spring/summer of 2021 I hope that things will return to normal.

Medical Myths about Aging

By Ray Schilling | andropause, cholesterol, Circadian rhythm, Dementia, diet, exercise, fractures, heart attack, High Blood Pressure, Hormones, lung cancer, Menopause, Mortality, Obesity, Pain, Smoking, Stroke

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

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.

Poor Diets Threaten Americans and Cause Diseases

By Ray Schilling | alcohol, Alzheimer’s disease, Cardiovascular disease, diet, exercise, fish oil, Fitness, food, heart attack, Hormones, lifestyle, Lung Disease, Nutrition, Obesity, polyunsaturated oil, Smoking, Stroke, sugar

A new Federal Nutrition Research Advisory Group stated that poor diets threaten Americans and cause diseases. More than 500,000 people in the US are dying every year because of poor nutrition. 46% of adults have unhealthy diets; but children have even more, namely 56%. In 1979 the US healthcare cost was 6.9% of the gross domestic product. Compare this to 2018 when the US healthcare cost was 17.7% of the gross domestic product.

The Federal Nutrition Research Advisory Group states: “Poor diets lead to a harsh cycle of lower academic achievement in school, lost productivity at work, increased chronic disease risk, increased out-of-pocket health costs, and poverty for the most vulnerable Americans.”

You can improve your diet quality

When you start cutting out junk food and other processed foods, the quality of your food intake is improving. Eat more vegetables, and fruit. Eat wild salmon, which provides omega-3 fatty acids. Do not consume vegetable oils like soybean oil, canola oil, safflower oil, corn oil and grapeseed oil. They all contain omega-6 fatty acids. Omega-6 fatty acids are essential fatty acids and they convert mainly into energy. But the problem is that our western diet contains too many omega-6 fatty acids. Omega-6 fatty acids can convert into arachidonic acid, which causes inflammation. This in turn can cause heart attacks and strokes on the one hand and arthritis on the other. Use cold-pressed extra virgin olive oil instead for cooking and on salads.

How does poor quality food affect your health?

Researchers are aware of trans fats causing Alzheimer’s disease, heart attacks and strokes for a long time. They increase the bad LDL cholesterol, decrease the good HDL cholesterol. Rancid oils contain free radicals that oxidize LDL cholesterol and attack the lining of your arteries through small dense LDL cholesterol. The FDA has started to initiate steps in 2015 to make the use of trans-fats in the food industry illegal. Completion of this in the US occurs in early 2020.

Japanese trans-fat study (Alzheimer’s disease)

This Japanese study followed 1,628 Japanese community residents (men and women) for about 10 years. Researchers used the typical trans fatty acid, elaidic acid to monitor the accumulation of trans fats in patients. This is possible with a simple blood test, which serves as a marker for industrial trans fats. 377 participants developed dementia (247 Alzheimer’s disease and 102 vascular dementia). Based on the blood elaidic acid levels earlier in the study individuals with higher trans-fat levels were more likely to develop Alzheimer’s disease as the study progressed. Patients whose trans-fat blood levels were in the higher range were 50% to 75% more likely to develop Alzheimer’s disease or dementia.

Diseases caused by poor lifestyle habits

It is important to review the diseases that shorten life expectancy due to having poor lifestyle habits. Note that it is not only your dietary habits that determine this, but in addition, several lifestyle factors.

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, consuming too much alcohol causes cancer of the colon and rectum 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 your system and adds to 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.

Poor Diets Threaten Americans and Cause Diseases

Conclusion

A new Federal Nutrition Research Advisory Group has been formed, which noted that many Americans follow very poor diets. 46% of adults in the US have unhealthy diets; but children have even more poor diets, namely 56%. This is of concern, because in time this causes a variety of diseases discussed here. Instead of just treating the symptoms of these diseases, it is important to improve the diet people are on, which prevents the development of these diseases. A well-balanced diet not only prevents diseases, it also leads to longevity and healthy aging without Alzheimer’s disease. Take care of what you eat, and be sure it is healthy!

Fat Deposits Mean Higher Covid-19 Risk

By Ray Schilling | Diabetes, diet, food, heart attack, Infectious Disease, Inflammation, lifestyle, Mortality, Nutrition, Obesity, Stroke, sugar, Weight loss

A new study showed that fat deposits mean higher Covid-19 risk. This study was reviewed here.

The article is based on the June 10, 2020 publication of the British Medical Journal.

They did large population studies showing that obesity is an independent risk factor for severe disease and death from Covid-19. One study with 428,225 participants had 340 admitted to hospital with confirmed Covid-19 coronavirus. 44% of them were overweight and 34% were obese. Another study, the OpenSAFELY study used linked electronic health records. 17,425, 445 participants were included and 5,683 Covid-19 deaths occurred. In this study there were 29% overweight and 33% obese persons. The researchers noted a dose-response relationship between excess weight and severity of Covid-19. The researchers removed confounding factors like age, sex, ethnicity, and social deprivation.

Critical illness and death rates in overweight and obese people

They realized that critical illness caused by Covid-19 was increased compared to normal-weight people as follows.

Covid-19 risk 44% higher in overweight people
Covid-19 risk 97% higher in people with obesity

This means that the risk for serious illness from Covid-19 was 1.44-fold for overweight persons and 1.97-fold for obese persons compared to normal-weight controls. The OpenSAFELY study also looked at the death rates from Covid-19 for people with obesity. Two obesity categories were investigated: obesity with a BMI of 30-34.9 and BMI of greater than 40 compared to normal-weight controls. Here are the death rates.

BMI of 30-34.9: 1.27-fold increased risk
BMI of greater than 40: 2.27-fold risk

Possible mechanisms explaining fat deposits mean higher Covid-19 risk

The researchers mentioned three possible mechanisms why overweight and obese people may have higher Covid-19 disease and death rates than normal-weight controls.

First, angiotensin converting enzyme-2 is found with higher frequency in fat cells of overweight and obese persons. Researchers are aware of the fact that the Covid-19 coronavirus uses this enzyme to enter body cells. It may also be the reason that fat cells become reservoirs that can shed virus for much longer than in normal-weight people with less fat cells. They pointed out that others have seen this also and found it with other viruses. In the case of influenza A, obesity prolonged viral shedding by 42% compared to normal-weight controls. And with H1N1 influenza obesity was an independent risk factor for hospitalization and death.

Weaker immune system, more lung resistance

Secondly, any virus can weaken the host’s defence of the immune system. Researchers showed this previously with the influenza virus. But now with Covid-19 coronavirus the cytokine storm due to a weak immune system is a major factor in making the viral infection worse. A lack of vitamin D is another factor in promoting the cytokine storm.

Third, obesity decreases lung function and it is difficult to improve this. There is greater lung resistance in the airways and it is difficult to expand the lungs in obese patients. When the doctor transfers patients with obesity to the intensive care unit, it is more difficult to increase their oxygen saturation with artificial ventilation.

Unhealthy environment, so fat deposits mean higher Covid-19 risk

The researchers point out that we live in a very unhealthy environment. In 2016 there were 1.9 billion people worldwide who were overweight or obese. These figures are rapidly rising. Presently about 65% to 70% are overweight or obese in the UK or the US. Obesity causes high blood pressure, heart disease, strokes, type 2 diabetes and cancer. We are all surrounded by processed food with extra salt, sugar, wheat and other unhealthy ingredients. The high mortality and deaths rates of Covid-19 in overweight and obese people point to the problem that society has.

Reduce salt, sugar and saturated fats in food

The culprits are salt, sugar and saturated fats. Merchants and food producers must reduce them in processed food. In the UK new government regulations have already resulted in lower salt content in foods. As a result, there is less high blood pressure and cardiovascular disease is in decline. All nations need to reduce salt, sugar, and saturated fat. When the weight comes down, we all are less prone to catching dangerous viruses.

Fat Deposits Mean Higher Covid-19 Risk

Conclusion

The pandemic has taught us a new lesson, namely that overweight and obese people are at higher risk of contracting Covid-19 coronavirus. In a research paper of the British Medical Journal concrete figures showed that the Covid-19 risk is 44% higher in overweight people and that it is 97% higher in people with obesity. The OpenSAFELY study also showed that obese people with a BMI of 30-34.9 have a 1.27-fold increased risk of catching Covid-19. But morbidly obese people with a BMI of greater than 40 have a 2.27-fold risk of catching Covid-19. There is a clear linear dose-response curve between the amount of fat a person accumulates and the risk for Covid-19.

Cut out junk food and decrease your risk for Covid-19

Covid-19 is directly related to the amount of junk food we eat. As a result we can say that eating junk food increases the Covid-19 risk. The opposite is true also: sensible eating and cutting out junk food makes you lose some pounds, and your risk for Covid-19 decreases.
