Learn about Longevity from the Blue Zones

People who live in blue zones often turn 100 or older, so we can learn about longevity from the blue zones. The 5 most often cited blue zones are in Okinawa, Japan; Sardinia, Italy; Nicoya, Costa Rica; Icaria, Greece; and Loma Linda, California, United States. But there are many more blue zones throughout the world. These zones contain the most centenarians, people who have reached the age of 100. It is thought that it is the people’s lifestyle that makes them live much longer than the rest of the world.

Lifestyle of centenarians

People are active, are bicycling, walking, swimming, constantly on the go and they are careful about what they eat. They stay slim, but are muscular. Their diet consists mostly of vegetables and salads, with very little meat. They may consume a small piece of beef on Sundays, but not during the rest of the week. Fish may be a part of their diet two or three times per week.

Diet characteristic of blue zones

Sandee LaMotte  published an article on March 4, 2023 at CNN, which describes the diet consumed in blue zones. People in blue zones are active, handle stress well, are close to friends, have a purpose in life and are often members of a social or religious group. They eat mostly a plant-based diet and they stop eating before they are full.

The food consists of complex carbohydrates. No processed foods are eaten. The American Heart Association says: “Complex carbohydrates, such as beans, peas, vegetables and whole grains provide vitamins, minerals and fiber that can go missing in processed and refined foods. In addition, they are digested more slowly, and the fiber helps you feel full longer.”

Origin of blue zone foods

The blue zone food has its roots in the African, Asian, Latino and Native American diets. Dan Buettner originally published an article about the blue zones in the National Geographic Magazine. Recently he published a collection of 100 blue zone recipes in book form.

The Mediterranean diet is very close to blue zone eating.

What blue zone meals contain

Buettner said: “The five pillars of every longevity diet, including the blue zone, are whole grains, vegetables in season, tubers, nuts and beans. In fact, I argue the cornerstone of a longevity diet is beans.” People in blue zones eat similar foods as those who eat a Mediterranean diet, but they do not eat as much fish as people on a Mediterranean diet. People on a blue zone diet don’t eat any milk products. On the other hand, goat and sheep’s milk cheeses such as feta and pecorino are part of the blue zone diet. In the blue zones the consumption of purple sweet potatoes, sesame seeds, fresh vegetables and fruit are the major staples.

All of the meals contain complex carbohydrates, micronutrients and a whole variety of fiber.

Perhaps the important difference to the Standard American diet is that in the blue zone there is a lack of beef, hamburgers, processed foods and highly processed carbohydrates like bread, pasta, sugar-sweetened beverages, salty snacks like potato chips, candies, cookies and processed meats (bacon, sausages or cold-cuts). People in blue zones eat very little bread and if they do, they eat sourdough bread, which does not raise the blood sugar level as the highly refined white bread.

Recapturing healthy foods

So, what foods are blue zone people really eating? Tofu, quinoa, mushrooms, lentils, beans, turnip greens, artichokes, asparagus, chickpeas and spinach are the main staples of their nutrition. They stay away from sugar, rarely eat meat (once or twice per week) and otherwise have a healthy lifestyle. Scientists think that longevity comes from the healthy lifestyle and diet, which centenarians practice. Several longevity genes get activated as explained in this publication. This translates into living long lives with very few illnesses and experiencing energy until the end of their lives.

Conclusion

We can learn a lot from observing what centenarians eat and do. Scientist have investigated the lifestyle of people living in blue zones in various parts of the world. These zones contain the most centenarians, people who have reached the age of 100. People in blue zones eat mostly vegetables and very little red meat. They avoid sugar and processed foods. But they are also very active, have a rich social life and allow themselves enough sleep. Scientists accumulated evidence that genetic longevity switches are activated by the life style of people living in blue zones.  It is the activation of these epigenetic switches that are responsible for the longevity of people in blue zones.

Plant-Based Meat Alternatives are Healthier

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

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.

Extreme Heat and Heat Related Deaths

Extreme heat and heat related deaths are closely linked. A record heat wave hit the North West of the US and British Columbia in late June/early July. Many people died from heat stroke and from cardiovascular problems. Here I like to review the medical literature regarding extreme heat and heat related deaths. Also, why is it important to cool down? Much of what I like to communicate was published in a review article by CNN. But I also reviewed many other websites and added links below.

How does global warming contribute to the summer heat?

There are a few explanations how global warming drives the heat in summer even higher.  Essentially, what weather experts are saying is that the jet stream can get stuck in one place during a summer heat wave and the heat keeps getting more intense. Global warming is responsible for heat waves that are higher than in the past. Conversely, in winter global warming can produce cold waves that are colder than in previous years.

Why is extreme heat dangerous for us?

According to the CDC between 2004 and 2018 an average of about 700 Americans died from heat-related causes. The majority of deaths occurred between May and September. There are a number of observations that explain why more people die during a heat wave.

In 2006 there were widespread heat waves and as a result there was a peak in heat related deaths.

  • When people have pre-existing cardiovascular disease, this gets aggravated during a heat wave and the death rate from cardiovascular disease increases during a heat wave. About 25% of heat related deaths are due to an underlying cardiovascular disease.
  • Age by itself plays a big role in heat related deaths. People above the age of 65 are several times more likely to die from a heat related cardiovascular disease than the general population.

     Under reporting of heat related deaths

  • Many times, it is not clear whether a death is due to a medical condition or due to exposure to heat. A death certificate that reports a heart attack as the cause of death during a heat wave will be missed when statisticians attempt to get a number for heat related deaths after a heat wave.

Medical causes why extreme heat and heat related deaths are linked

Our body is used to an inside temperature range between 97 to 99 degrees Fahrenheit (36.1 to 37.2 degrees Celsius). The body can compensate in two ways to counter a rise of the body temperature from heat exposure.

  1. When the brain senses a rise in body temperature, the sweat glands open up and sweat is produced. The evaporating sweat cools down the body temperature.
  2. The body has a second coping mechanism to cool you down. The body can dilate its blood vessels and increase the heart rate. This brings the blood more to the surface. This is when your forehead and the extremities give off heat and you lower your body temperature.
  3. But with exposure to extreme high temperatures both of these mechanisms are not enough to decrease your core temperature.

Avoiding heat-related illness

  • The Mayo Clinic link explains that it is important to drink enough fluids to avoid dehydration. This helps with the second coping mechanism mentioned that cools you down (see above).
  • When the outside temperature rises beyond 86 degrees Fahrenheit (=30 degrees Celsius) it is wise to stay inside air-conditioned premises. This could be your house, if you have air-conditioning, an air-conditioned mall or a public building. A cool pool, bathtub, or cold cloths applied to your arms, legs and torso cool you down as well. Otherwise, intermittent cold showers or cold baths will do the same.

Health conditions that are a higher risk for heat related deaths

The population group at higher risk for developing heat-related illness and eventual deaths are infants and children up to age 4. In addition, anybody older than 65 years is also at risk. Pre-existing medical conditions like diabetes, heart disease and chronic lung disease (COPD) increase the risk of dying from excessive heat exposure. Being overweight or obese is also a risk factor. Heat exhaustion and heat stroke are conditions that require hospitalization.

Common heat-related symptoms

Symptoms of heat exhaustion are: profuse sweating, a pulse that is fast and weak, clammy skin, vomiting and nausea. In addition, there can be cramps in muscles, weakness, tiredness, dizziness, headaches and fainting.

Symptoms of heat stroke are: high fever of 104 degrees Fahrenheit (= 40 degrees Celsius) or higher. Take the temperature with a rectal thermometer to get the core temperature. Other symptoms of heat stroke are altered mental state (confusion, agitation, delirium and seizures). Further, the skin may turn red as the temperature increases, and there may be rapid and shallow breathing. The heartbeat races and the head may throb from a severe headache. Both patients with heat exhaustion and heat stroke need hospital care. Call an ambulance.

Extreme Heat and Heat-Related Deaths

Extreme Heat and Heat Related Deaths

Conclusion

We have to take extreme heat and heat related deaths seriously. Only when we employ counter measures will the death toll from heat related deaths go down. Prevention is everything. But if a person develops heat exhaustion and heat stroke swift transportation to a hospital is a must. This can often save a life. We all need adopt an awareness what our risks are regarding heat and heat related deaths. We need to apply early countermeasures by getting into cooler areas and by drinking enough fluids to prevent dehydration. Prevention is everything regarding extreme heat and heat related deaths.

Melatonin Is More Than a Sleeping Aid

Notably, the January 2021 issue of the Life Extension magazine informs you that melatonin is more than a sleeping aid. It contains an interview between Dr. Roman Rozencwaig and a Life Extension (LE) magazine reporter. It must be remembered that Dr. Rozencwaig dedicated much of his career to the healing effects of melatonin. Another keypoint is that in 1987 Dr. Rozencwaig published a paper together with two other researchers. Specifically, it showed that melatonin production by the pineal gland declines in older age. Markedly, they stated that this is the reason why people age and why diseases of aging develop. Another key point is that Dr. Rozencwaig also stated that taking oral melatonin can promote a healthier life.

Melatonin deficiency causing aging and various illnesses

With the aging process the pineal gland calcifies and melatonin production is steadily declining. Surely, along with this is a deterioration of the circadian hormone rhythm. Meanwhile, the neuroendocrine system in the brain gets disorganized. Accordingly, this causes various diseases to occur. To emphasize, Dr. Rozencwaig says that a proper balance between melatonin and neurotransmitters is what we need to maintain health and longevity. As a result, a daily intake of melatonin supports healthy aging and longevity.

The many clinical effects of melatonin

Oral melatonin tablets help you to fall asleep easier, particularly the population that is older than 60 years.

But besides that, melatonin has many other clinical effects.

  • Melatonin improves immunity, which improves resistance against infections. It helps also in cancer prevention
  • Melatonin maintains the circadian hormone rhythm by synchronizing pituitary and hypothalamic hormone production
  • It protects the brain and may prevent Parkinson’s disease, Alzheimer’s disease, multiple sclerosis, autism, and others
  • Melatonin modulates anti-inflammatory cytokinins in different diseases

Dr. Rozencwaig mentioned that melatonin slows down the aging process. There are multiple intertwining reasons for this. 

Melatonin’s actions against the aging process 

  • Melatonin regulates gene expression. This means that some signs and symptoms of aging can be reversed through genetic switches
  • Because melatonin regulates the immune response, the body is more protected against viral, bacterial and parasitic infections
  • Melatonin helps to overcome chronic inflammation that produces cytokines
  • Melatonin is also liver-protective through stimulation of an enzyme (AMPK). This enzyme regulates cellular metabolism.
  • There are other processes that melatonin is involved in: energy metabolism by protection and restoration of mitochondria.
  • Melatonin protects against osteoporosis by balancing and regulating bone formation versus bone loss.

More actions of melatonin

  • An important function of melatonin is the stimulation of antioxidant enzymes like glutathione peroxidase and superoxide dismutase (SOD)
  • Melatonin regulates sirtuins, which are proteins that maintain cellular health. They protect you from obesity, type 2 diabetes, cancer, heart attacks and strokes, dementia and more
  • As already mentioned, melatonin is a neuroprotective agent and may prevent Alzheimer’s and dementia
  • Melatonin stimulates apoptosis of cancer cells.
  • Oral health and melatonin are related. Melatonin suppresses herpes infections and periodontal disease. Melatonin prevents oral cancers to a certain degree. In addition, dental implants survive better when melatonin is present in saliva.

Prevention of cognitive decline

Dr. Rozencwaig mentioned that melatonin stops much of the cognitive decline of aging. To achieve this the following processes take place.

  1. Melatonin improves the sleeping pattern and increases the amount of REM sleep.
  2. During sleep melatonin removes toxic amyloid and tau proteins. We know that with Alzheimer’s disease these are the proteins that accumulate in the brain.
  3. Melatonin improves myelination of white matter in the brain. This prevents brain atrophy of old age.
  4. The brain is metabolically very active and produces toxic free radicals. But melatonin is a strong antioxidant dealing with free radicals. Melatonin can cross the blood brain barrier and stimulates enzyme production to eliminate toxic reactive oxygen species.
  5. Chronic inflammation also increases with age, but melatonin deals with this condition in the brain.
  6. Here are 3 subtypes of melatonin receptors. The body integrates the multitude of actions of melatonin with the help of these receptors.
Melatonin Is More Than a Sleeping Aid

Melatonin Is More Than a Sleeping Aid

Conclusion

Melatonin is a powerful antioxidant that has many other useful protective qualities as explained. The body integrates various functions like anti-aging, anti-free radical activity, neuroprotection in the brain and more. Melatonin even synchronizes pituitary and hypothalamic hormone production. This helps to integrate the effect of melatonin, which benefits the body in many ways. Melatonin prevents Parkinson’s and Alzheimer’s disease, multiple sclerosis, autism, obesity, type 2 diabetes, cancer, heart attacks, strokes and dementia. Melatonin production deteriorates from the age of about 60 onwards. It is important to supplement with melatonin at nighttime from that age on. Usually, you only need small amounts of melatonin, between 1mg and 3 mg at bedtime. This prevents most of the serious diseases of old age, stimulates your immune system and lets you age gracefully.

The Quality of Food is Important

Many authors wrote books about food; the quality of food is important. Recently I came across a book review regarding the book “The Way We Eat Now” by Bee Wilson. In the March 2020 edition of the health magazine “LifeExtension” Laurie Mathena interviewed Bee Wilson about her book.

Bee Wilson explained that there is a distinct history about the production of food throughout the centuries. She described 5 phases.

  1. During the hunter/gatherer time people were eating a low-fat diet with berries, wild greens and wild animals.
  2. Stage two began around 20,000 BC. It was the agricultural age with a switch to cereals. At that time the population experienced rapid growth.

More stages

  1. Only a couple of centuries ago, agriculture made progress with crop rotation and by adding fertilizers. This led to a more varied diet. People ate more vegetables, less starchy food and animal protein.
  2. After the Second World War there was a major food transition. Processed food was introduced. People started eating more fat, meat, sugar and a lot less fiber. We are now experiencing a phenomenon that we are simultaneously overfed, but undernourished. We get too many calories, but our diet is poor in nutrients. This type of diet causes obesity and degenerative type illnesses.
  3. Stage 5 involves people abandoning junk food and eating more vegetables and fruit again. The more knowledgeable people are about the link between a good diet and health, the healthier people eat. This stage requires governments and other organizations to do their part in assisting people to make that food transition.

Food labeling changes in Chile

Here is one example of how governments can make a difference. This happened in Chile. Chile used to have the highest consumption of sugary beverages in the world. Prior to 2016 the average consumer in Chile bought more than 50% of the food as ultra-processed. This resulted in Chile having the second highest obesity rate after Mexico. The government of Chile decided in 2014 to introduce very simple labels for every food item. The government of Chile demanded that all the foods with too much sugar, high saturated fat, food high in salt and high in calories had proper labels. These labels are simple, hexagonal warning labels.

Warning labels

For instance, if a food product had too much salt in it, it would say in the hexagonal label: “Warning: high in salt”. As the labels had the effect of lowering sales, the food companies reformulated their products very quickly to stay under the threshold triggering the food warning. In 2016 Chile also decided to tax unhealthy foods higher. The government taxed sugar-sweetened colas with an 18% extra tax. Schools had to abandon junk foods sales.

Quality of food

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 grape-seed 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 hand.

The omega-6 to omega-3 ratio is important

In the past a healthy ratio between omega-6 and omega-3 was 4:1 or less. The average American now eats food with 16-times the amount of omega-6 fatty acids than omega-3’s. This is an omega-6 to omega-3 ratio of 16:1. No wonder people get sick with degenerative diseases.

Brain health maintained by eating enough omega-3 fatty acids

Here is a study that looked at brain structure using MRI scans. 3660 participants aged 65 received MRI brain scans. The researchers recorded their food intake with questionnaires. They rescanned 2313 of these individuals 5 years later. The group highest in omega-3 consumption was compared to the group with the lowest omega-3 consumption. Blood tests were also done both initially and 5 years later to verify the omega-3 intake. The researchers found that the higher omega-3 group had less subclinical infarcts and the white matter of the brain was of a better grade. They concluded that fish consumption, the major source of omega-3 fatty acids, had a beneficial effect on brain health later in life, preventing Alzheimer’s disease.

Cook your own food, do not eat out frequently

When you cook your own food, you can choose the right foods as you shop. Stay away from the “dirty dozen”, which is poisoned with insecticides, herbicides or pesticides. Instead you can buy organic foods that have not been sprayed with toxic substances. When you eat out, you have no choice about what you eat. Food in restaurants also contains food preservatives that are not labeled in North America, but that would be labeled in restaurant menus in Europe. In addition, food in restaurants often contains too much salt, too much sugar and the wrong oils. Omega-6 fatty acids are much cheaper than olive oil, and as a result this is what the chef uses.

Transition from stage 4 to stage 5

When you want to transition from stage 4 to stage 5 regarding your food composition you are swimming against the stream of establishment. At this point you are more or less alone when you want to abandon French fries, processed food bars, hamburgers and sugary soft drinks. But the more you eat at home, the more you take out your lunch box with food prepared at home, the more you are winning the war against convenience foods. It is what you put into your mouth, which is the fuel for your body. Don’t compromise regarding the quality of your food!

The Quality of Food is Important

The Quality of Food is Important

Conclusion

The quality of food is important. We have been inundated by ads from the food industry that we should eat fast foods (hamburgers, French fries), processed foods like power bars and drink sugary drinks. We have met the entire lineup on television! But it is best to buy basic foods and prepare all your food from scratch. Be careful that you avoid the “dirty dozen” foods. If you want to eat these, buy the organic food versions. This way you avoid pesticides and other poisons. Stick to extra virgin olive oil as a fat source and avoid vegetable oils. Soybean oil, canola oil, safflower oil, corn oil and grape-seed oil contain a lot of omega-6 fatty oils.

Inflammation caused by vegetable oils

These cause inflammation in your blood vessels and joints. The end result are heart attacks, strokes and arthritis. I also eat a lot of wild salmon and other seafoods, a great source of omega-3 fatty acids. In addition, I take two capsules of molecularly distilled fish oil in the morning and at night. Eat more vegetables and fruit. You are now paying attention to the fact that the quality of food is important.

Clinical Applications of the Fasting Mimicking Diet

Dr. Kurt Hong, professor of clinical medicine spoke about clinical applications of the fasting mimicking diet in Las Vegas. This was at the 27th Annual World Congress on Anti-Aging Medicine on Dec. 14, 2019. Although he spoke on various forms of fasting, he concluded that the fasting mimicking diet had the best results and was most consumer-friendly.

How we age

Dr. Hong reviewed the processes of aging. We age, because our cells experience oxidative damage and our telomeres (the end caps of our chromosomes) get shorter in time. We also age, because there are genetic mutations in our cells’ DNA and our mitochondria are aging as well. The mitochondria are the small energy packages inside the cells that give us energy. When people age, they have lost mitochondria, there is less energy that the body makes out of food and we feel chronically tired.

Above the age of 65 we are also likely to develop diseases of various organs:

  • Heart disease: 31%
  • Cancer: 24%
  • Chronic lung disease (lower respiratory disease): 21%
  • Alzheimer’s disease: 13%
  • Diabetes: 11%

Women are generally healthier than men and their life expectation is 4 to 5 years longer than that of men.

Cellular and molecular aging

Longevity researchers have done mouse experiments and human clinical trials for decades. Dr. Hong asked the question: how much longer could humans live, if we could cure cancer, heart disease, stroke and diabetes? The answer is: 13 years. But if we transfer the animal data to humans it should be 30 years of longer life. Why is there such a discrepancy? The answer is that it is easy to force good lifestyles onto animals, but humans are resistant to changes. Humans have their habits; they like to continue to smoke and eat fast food instead of switching to a healthier Mediterranean diet. Humans also resist a regular exercise program. And they do not want to hear that they should replace missing hormones with bioidentical ones. The result is that we humans will prolong our lives only by less than 50% of what we could achieve.

The concept of intermittent fasting

Dr. Hong stated, that ten thousand years ago, people did not always have enough food to eat. They were forced to intermittently fast. That did not mean that they had long life expectancies, as there was no cure for any disease. But one fact was true: the body learnt to rejuvenate itself during periods of fasting. And these longevity genes are still present in our genes. But they will only help us when we actually fast for some periods of time.

Dr. Hong reviewed what kind of fasting methods are available.

Prolonged fasting and juice fasting are not among the options. With prolonged fasting electrolyte disturbances become an issue. Juice fasting does not remove enough calories and nutrients. This, however is needed to allow the body to stimulate the longevity genes.

How fasting diets work

Dr. Hong explained that there are essentially 5 fasting diets that are effective in regulating the key nutrient sensitive pathways of IGF-1, TOR and PKA. This increases cellular protection and maintenance. It also increases activation of stress resistance pathways and removes and replaces damaged and dysfunctional cells. Finally, a fasting diet also reduces inflammation, which is often the start of disease.

A review of the 5 fasting diets

Time-restricted eating (TRE)

With TRE the person fasts for 12 to 16 hours every day. The person restricts the daily food consumption to a 4- to 12-hour window. The disadvantage is that this fast is done every day. The period of fasting may not be long enough to change the metabolism, where the above-mentioned effects take place.

Alternate-day fasting  

This is a 24-hour fast every other day with a 1:1 day eating-fasting cycle. This does not appear to be physiological and is disruptive with regard to social activities.

5:2 intermittent fasting

With this fast you fast for 2 days every week. With this 2:5 eating-fasting cycle the person fasts for 2 days every week; the other 5 days you eat as much as you desire.

Although this is effective, it can be quite disruptive to your lifestyle.

Periodic fasting

You fast for 48 to 72 hours every couple of months. This fast is socially more acceptable. It is not that often, just a couple of times in a year. The question remains whether it is effective in changing the metabolism to trigger the effects mentioned above.

Fasting-mimicking diet (FMD)

The original suggestion by Dr. Longo, the inventor of the FMD was that you should fast for 5 days once every month. Since then he has modified it and said that you can achieve similar metabolic changes, if you only fast for 3 days and do this a couple of times per year. I have done the FMD since December 2017 and I adhere to the original schedule of doing the FMD monthly for 5 days. This has provided me with more energy. It is easier to keep my body mass index in the 21.0 to 22.0 range. Dr. Hong explained that the FMD allows you to eat, but it tricks the body into acting like you are fasting. Because you are eating 500 to 600 calories per day, you are getting some fluid and nutrients, so the hunger pangs are tolerable.

More details about the FMD

Here is Dr. Hong’s summary about the FMD: “The stomach sees food, while the cells see fasting”. Dr. Hong said that the FMD is the most user-friendly method of fasting. It also has had the most scientific studies to validate that it is indeed working. Poorly functioning mitochondria and misfolded proteins are removed by a process of phagocytosis. The FMD reduces heart disease, cancer, and neurodegenerative disorders. Stem cell production also gets a boost. This promotes cell regeneration and reduces risk factors of premature aging.

Publication on the effectiveness of the FMD

A publication came out in 2017 reporting about the findings of a clinical trial regarding the FMD.

Researchers followed markers of aging, diabetes, cancer and cardiovascular disease in 100 volunteers. They underwent a FMD for 5 days on 3 consecutive months. The results were astounding. The body mass index, the fasting blood sugar level, triglycerides, total and LDL cholesterol and the CRP were all lower. CRP stands for C-reactive protein, which measures the degree of inflammation in the body. The blood pressure was also lower. Overall the 5-day FMD was a safe method with no side effects. The FMD reduced markers and risk factors of aging and age-related diseases. In doing so it prolongs life by reducing the likelihood of coming down with disease.

Who should abstain from fasting?

Dr. Hong mentioned that the FMD is not for everybody. Pregnant women should refrain from going on it, also type 1 and type 2 insulin dependent diabetics. Anybody who has a sign of an active infection (coughing, having a fever or diarrhea) should be excluded. Other exclusions are people who are underweight (BMI less than 18.5) or are malnourished (protein deficiency). Patients with heart failure and advanced kidney or liver disease should not take part in a fasting program.

Autoimmune diseases and FMD

The myelin sheath around the axon of nerve cells in the central nervous system are supported by oligodendrocytes. In multiple sclerosis (MS) patients T lymphocytes activate macrophages and B cells to produce autoantibodies. They destroy oligodendrocytes breaking down the insulating barrier of the myelin sheath. In MS patients the broken-down myelin sheath suppresses the electrical impulses transmitted through the nerve fibers. The FMD led to clinical improvements.

In a pilot study intermittent fasting changed the gut flora into a healthier flora.

This triggered the immune system in the gut to make less inflammatory T cells producing the IL-17 cytokines. There was also an increase in regulatory T helper cells.

Inflammatory bowel disease (IBM) can be improved with several courses of FMD. As the authors showed, intestinal inflammation improved with FMD. The intestinal gut flora improved with the FMD and it promoted intestinal regeneration.

Reversal of physical and functional decline

The fasting mimicking diet (FMD) has a variety of effects on the human body. Dr. Hong showed a slide where we could see that ketone bodies, cortisol and ghrelin levels are increased in the blood. At the same time glucose, insulin, leptin and IGF-1 levels are reduced. In addition, triglycerides and LDL levels are getting lower. Inflammatory markers including the C-reactive protein (CRP) are reduced as well.

Effects of the FMD on various organs in the body

A look at all of the organs shows that in the liver the ketone body production and insulin sensitivity are up. Glycogen production in the liver as well as the liver size are down.

The intestines produce ketone bodies. In the skeletal muscles the insulin sensitivity is increased, while the muscle structure and function are improved. In the brain the hunger feeling increases the release of neurotropic factors including the neuropeptide Y. Cognitive function and stress resistance increase with the FMD. The FMD reduces inflammation and oxidative stress in the brain. With respect to the cardiovascular system the heart rate drops down and blood pressure gets lower. The insulin production in the pancreas is reduced.

Fatty tissue

In fatty tissue lipolysis is up and also the production of adiponectin. This is a protein hormone involved in glucose and fatty acid metabolism. Insulin sensitivity with the FMD is also increased. On the other hand, the FMD reduces fat mass, leptin production and inflammation.

The FMD is the solution to preventing disease and prolonging your life

All of these effects lead to a reversal of physiologic and functional declines. Age-related metabolic diseases like type 2 diabetes are postponed or eliminated. The FMD prevents neuro-cognitive decline like Alzheimer’s disease. In addition, the risk of developing cancer is getting lower. In summary, the FMD improves the health-span, quality of life and can prepare you for a long life.

Clinical Applications of the Fasting Mimicking Diet

Clinical Applications of the Fasting Mimicking Diet

Conclusion

Dr. Kurt Hong is a professor of clinical medicine at UCLA. He gave a talk at the 27th Annual World Congress on Anti-Aging Medicine in Las Vegas on Dec. 14, 2019. He discussed what we could do to help patients with various autoimmune diseases like multiple sclerosis, rheumatoid arthritis and inflammatory bowel disease. It turns out that the fasting mimicking diet (FMD) is the best solution to reduce inflammation and modify  the autoimmune response from aggressive T lymphocytes. With the FMD you consume only 500 to 600 calories per day for 5 days every month. The rest of the days of the month you eat a healthy Mediterranean-type diet.

Fasting mimicking diet, the best way to treat autoimmune diseases

Dr. Hong explained in detail what cellular mechanisms are at work to achieve the modification of the immune system in autoimmune diseases. The FMD is also the solution to slow down aging in healthy people. Dr. Hong discussed clinical applications of the fasting mimicking diet fort autoimmune diseases. It is easier to prevent disease than it is to cure an illness. The FMD is an easier way, because you don’t fast completely, you only reduce your food intake to the bare minimum, but your body “thinks” that you are fasting.

Ultimately, this approach does take some effort, and it does take time to familiarize yourself with it. If patients do it for the first time, they will experience some hunger, the first and second day tend to be a hurdle! Once you make it part of a health routine on a regular basis, it is a lot easier.

Preserving Youthful Power

Dr. Christopher W. Shade (PH.D.) presented a lecture in Las Vegas on Dec.13, 2019 talking about preserving youthful power. The presentation was at the 27th Annual World Congress on Anti-Aging Medicine and his title was “Building Youthful NAD+ Power with Precursors, Sirtuin-Activating Compounds, and Methylation support”.

In the first place, nicotinamide adenine dinucleotide (NAD+) is a signalling molecule between the DNA of the nucleus of cells and the energy producing mitochondria that reside in the cells. The exact nature of the interaction is described in this review article. It describes how stress leads to a depletion of NAD+ and sirtuins, and causes accelerated aging. On the other hand, calorie restriction and exercise lead to increased production of NAD+, activation of sirtuins and longevity.

Details about low NAD+ activity

It is important to realize that when NAD+ is below a critical level the following disease states can develop. First, in the brain it is Alzheimer’s disease and neurodegenerative disease. Second, in the eyes macular degeneration and keratoconjunctivitis sicca can develop. Third, severe plaque-type psoriasis can occur in the skin. Fourth, the pancreas develops hyperinsulinemia and metabolic syndrome. Fifth, type 2 diabetes can make your muscles weak. Sixth, sarcopenia with loss of muscle mass and cardiovascular disease in the heart can also develop. Seventh, the liver reacts to the metabolic syndrome by causing hepatic steatosis. Metabolic syndrome causes inflammatory cytokines in the fatty tissue. Eighth, the lungs react by developing chronic obstructive pulmonary disease. Ninth, your blood can get endotoxin-induced inflammation and sepsis from bacteria. A lack of NAD+ causes all of these negative changes simultaneously in the body.

In fact, when a person exercises regularly, uses intermittent fasting as a tool of calorie restriction and takes supplements of NAD+ all of these negative processes stop and sirtuins are activated restoring the body to a more youthful condition.

Summary about the effects of NAD+

In other words, NAD+ is important for cardiometabolic health, energy balance, liver health, immune health and cognitive health. NAD+ is also involved in maintaining the membrane polarity of cell walls. The blood /brain barrier and the gut/blood barrier are also kept intact by NAD+. In addition, NAD+ is involved in detoxification and control of the action of free radicals. It also is important to control Inflammation. For these reasons, it is not a surprise that people with normal NAD+ function will be healthier than those who have a problem with this.

Sugar reduces NAD+ to NADH

It is important to note that scientists could show in animal models and in humans that sugar overconsumption leads to the reduction of NAD+ to NADH. All of the negative effects described above for low NAD+ are then coming true. NADH is a reduced and disabled form of the oxidized NAD+. In essence, this substance has no biological action.

Energy metabolism

Biochemists have determined with regard to the energy metabolism of mitochondria that there are three occasions where enzymes are dependent on NAD+. Without NAD+ the energy-providing oxidative metabolism in mitochondria would not take place. As NAD+ is lower in older age, this explains why an aging population has less energy. In addition, as we age, the number of mitochondria per cell is decreasing. That is to say that an aging population has less energy than youthful people.

Other factors that are important in preserving youthful power

The AMPK signalling pathway

AMPK stands for 5′ AMP-activated protein kinase. This is an enzyme that consists of three protein portions. In humans it is expressed in liver, brain and muscle tissue. It provides energy in the liver by fatty acid oxidation. In muscles it stimulates glucose uptake and fatty acid oxidation. AMPK also inhibits cholesterol synthesis, lipogenesis and triglyceride synthesis. Fasting and exercise can stimulate AMPK production, which in turn will stimulate SIR1 genes and NAD+ production. This is especially happening in muscle tissue. To put it another way, there are a close-linked metabolic reactions between NAD+, AMPK and sirtuins.

Balance between AMPK, NAD+ and methylation

Given the right circumstances this can lead to detoxification, longevity and energy. This is what intermittent fasting and exercise can do for you. AMPK needs high NAD+ levels to give you all of the benefits. But NAD+ must be balanced with methylation. This is a somewhat difficult subject to explain, but the link explains it in somewhat technical terms. In other words, with a balance of the body’s biochemistry the person is healthy. When there is a disbalance, you get sick.

Practical application how to supplement for preserving youthful power

Dr. Shade asked the rhetorical question: how can we achieve a balance between NAD+ and methylation?

His answer is to supplement with the following supplements.

  • Trimethylglycine (Betaine) 2‐5g/day
  • Vitamin B2: 10‐30mg/day
  • SAMe or methylcobalamin 1000‐3000mcg/day
  • Measure Homocysteine as marker of methylation; if it is low, the methylation pathway is normal and there is balance.

Next: how to we raise NAD+? The answer is by cardio-metabolic blending.

  • Berberine and quercetin (they are respiratory chain modulators)
  • Resveratrol, silymarin and lipoic acid (they are liver kinase B1 activators)
  • Resveratrol or pterostilbene and quercetin (they are sirtuin activators)
  • Nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) 200- 400 mg per day
  • Trimethylglycine (Betaine) 2-5 grams per day and methylcobalamin, B2, and others (methylation support)
Preserving Youthful Power

Preserving Youthful Power

Conclusion

It is difficult to describe energy flow in biochemical terms. Dr. Christopher W. Shade did exactly that in a lecture he gave at the 27th Annual World Congress on Anti-Aging Medicine in Las Vegas on Dec.13, 2019. The key for preserving youthful power is to balance the metabolism that occurs in the nucleus of the body cells with the metabolism taking place in the mitochondria. The mitochondria are the energy producers, but the steering of this occurs through the metabolic products from the cell nucleus. NAD+ plays a key role in our energy metabolism. But there is an interplay with AMPK, which stands for 5′ AMP-activated protein kinase. Sirtuin genes interact with these messenger molecules as well and this is where longevity comes in.

Longevity through sirtuin stimulation

Sirtuins are longevity genes that help us get more energy for a longer period of time. Regular exercise stimulates this complex biochemistry giving us extra NAD+ for energy. Intermittent fasting also stimulates sirtuins, which adds to the extra energy and gives us longevity. This is not a bad deal when you look at it from a distance. We can achieve a lot preserving our energy through an active life style. Supplements can be an auxiliary measure, but they are not effective enough without positive lifestyle choices.

Replacing Part Of Red Meat With Fish Shows Health Benefits

A Danish study has shown that replacing part of red meat with fish shows health benefits.

The research was done by a PhD student and pointed out that men above the age of 50 were particularly benefitting from fish substituting part of red meat in their diet. Women in the childbearing age also benefitted greatly. On this diet pregnant women as well as the unborn children become healthier.

Risk versus benefit analysis

Sofie Theresa Thomsen, the PhD student who conducted this study did risk-benefit assessments regarding partial substitution of beef with low-mercury fish. Red and processed meat contains saturated fat, which is added to the other saturated fat in the Danish diet. Red meat and processed meats have been associated with colorectal cancer and some other cancers. But red meat also contains beneficial iron. In contrast, fish contains a lot of omega-3 fatty acids that are anti-inflammatory and also contains vitamin D. But one has to be careful about methylmercury content in fish. I reviewed fish, mercury contamination and the benefits in this link.

In her calculations Sofie Theresa Thomsen replaced 350 grams of beef per week with 350 grams of low-mercury fish per week.

If all the Danish households would do this partial beef/fish exchange, the Danes would gain 7,000 healthy years of life annually. This includes, among other health conditions, the prevention of 170 deaths from coronary heart disease.

What kind of fish can you eat?

As the link above 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 consume low mercury fish and shellfish, like mackerel, herring, wild salmon, shrimps or clams, pregnant women benefit greatly from the beef/fish exchange. Tuna is too high in methylmercury to be included in the beef/fish exchange. If you were to include tuna in this, you would experience a health loss.

Vitamin D and iron

The study showed further that a partial exchange of beef by fish would reduce the number of Danes who are vitamin D deficient. The 350 grams of fish per week are sufficient to significantly raise the vitamin D blood level. Conversely, replacing a part of the beef intake with fish does not cause iron deficiency problems.

Who benefits most from replacing part of red meat by fish?

Sofie Theresa Thomsen asked who would benefit most from such a beef/fish exchange diet.

On the one hand it is the older than 50 year male population who is at a significant risk of developing heart attacks. The fatty fish with omega-3 fatty acids reverses some of the plaque in the arteries and keeps coronary arteries open. This prevents heart attacks and strokes.

On the other hand pregnant women and their children benefit greatly from the beef/fish exchange diet. The women will feel more energy and their offspring will have healthy brains.

Replacing Part Of Red Meat With Fish Shows Health Benefits

Replacing Part Of Red Meat With Fish Shows Health Benefits

Conclusion

A study from Denmark analyzed what happens when a person exchanges 350 grams of beef with low mercury fish or shellfish per week. The conclusion was that Danes would gain 7,000 healthy years of life annually. Among these is the prevention of 170 deaths from coronary heart disease. But the most lives saved would be among men older than 50 years due to heart attack and stroke prevention. Pregnant women are also benefitting tremendously, not only for themselves, but for their children. The fish needs to be low mercury fish, as mentioned above, as mercury is a central nervous system toxin. Tuna is too high in mercury.

I have cut out red meat and meat products from my diet since 2015, when the WHO came out with the statement that red meat causes colorectal cancer. As a result I eat a lot more low mercury seafood and shellfish.

The Foods That Are Killing Us

There is an article in a CNN report talking about the foods that are killing us. This review is based on an article in the Lancet. The Lancet study was based on a global review of eating habits in 195 countries. The question in the study was which of 15 food items caused the diseases that killed people. The answer was surprising. There are either omissions or unhealthy components of foods that kill us. Here is a list of 12 food groups that are problematical.

A dozen foods that were found to be problematical in the global review

  • Diet high in sodium (4 grams per day, which is 86% above the optimal level)
  • Low intake of whole grains (only 23% of optimal levels)
  • Low fruit intake
  • Diet high in trans fatty acids
  • Low omega-3 fatty acid diet (due to low intake of sea food)
  • Diet low in calcium
  • Diet low in fiber
  • High intake of sugar beverages or sugary foods (49 grams of sugar per day)
  • Processed meat intake too high (4 grams per day, 90% more than optimal)
  • Red meat consumption too high (27 grams per day, 18% higher than optimal)
  • Nut and seed intake too low (only consuming 12% of desired amount)
  • Diet low in milk (16% of desired amount)

Each of these components or several of them in combination create deficiencies in us or overburden us to the point where we can get sick and disabled.

Different countries have different eating habits

Globally there were 11 million deaths found in 2017 and 255 million years of disability because of various dietary inadequacies.

Here is the lineup of the leading causes of death:

  • cardiovascular disease with 10 million deaths and 207 million years of disability.
  • Cancers caused 913,090 deaths and 20 million years of disability.
  • Type 2 diabetes caused 338,714 deaths and 24 million years of disability.

This was broken down into statistics for each of the contributory countries. Here I am only citing some pertinent data that shows the importance of balanced meals for a healthy life expectancy.

Different death rates in various countries

There were big differences in terms of cardiovascular disease deaths according to various regions. Central Asia had the highest death rate with 613 deaths per 100,000 people per year. In contrast the high-income Asia Pacific group had only a cardiovascular death rate of 68 per 100,000 people per year.

Cancer deaths were highest in East Asia with 41 deaths per 100,000 people. The lowest cancer rate was found in North Africa and the Middle East with 9 deaths per 100,000 people.

Among the 20 most populous countries Egypt had the highest diet-related deaths, namely 552 deaths per 100,000 people. On the other hand Japan had the lowest of all diet related deaths with 97 deaths per 100,000 people. 

Some highlights how unhealthy foods kill us

Globally people only eat 12% of the desirable amount of nuts and seeds. They only drink 13% of what they should consume in terms of milk. People worldwide eat 23% of the desirable amount of whole grains.

Nuts and seeds contain mono- and polyunsaturated fats and omega-3 fatty acids, which lower your risk of getting heart attacks and strokes.

Milk is a good source of calcium, protein, minerals and vitamins. However, milk, yogurt or cheese should be consumed as low fat varieties. Alternatively people who do not consume milk should look for protein carriers such as soy milk or pea milk.

If you eat nuts and vegetables you can largely compensate for low milk consumption. If you don’t get enough whole grains, you are missing a whole lot of nutrients. This makes you more vulnerable of getting cardiovascular disease, hypertension, type 2 diabetes, colon cancer, and obesity.

Other unhealthy foods can kill us

The WHO has labelled red meat and processed meat as being carcinogenic

Studies clearly showed a higher than normal rate of colorectal cancer in those who consumed larger amounts of red meat and/or sausages.

Sugar overconsumption

Sugar overconsumption leads to a variety of conditions. Weight gain with the development of obesity and type 2 diabetes are common when you eat too much sugar. But even cancer like colorectal cancer and pancreatic cancer is more common in people who overindulge in sugar or sugary drinks. Sugar consumption raises your triglyceride and LDL level. This will eventually lead to hardening of the arteries, heart attacks and strokes.

Gout develops with purine containing foods

Gout can be caused by consuming a lot of red meat combined with copious amounts of beer. This is how royalty in the Middle Ages suffered from gout attacks. Gout had the nickname of “Disease of the affluent.” Both beer and red meat contain a lot of purines, which the kidneys cannot handle. The uric acid crystals that precipitate around joints cause excruciating pains.

 What the global health study showed

Researchers of the global health study stated that improving the diet habits could potentially eliminate 1 in 5 deaths globally. Dietary risks for major diseases like heart attacks, strokes and cancer are independent from sex, age and socioeconomic status.

Three dietary factors stood out: too much salt, too little fruit and too little whole grain. These three items were responsible for 50% of diet-related deaths and 66% of “disability-adjusted life years”. The authors used this expression to describe how years of disability had their root in diet deficits (e.g. too little fruit) or overdoses of unhealthy food components (e.g. salt).

The leading dietary risk factors are too much salt, low whole grain, low fruit consumption, low vegetable intake and low omega-3 fatty acid consumption. On top of that come the previously established risks due to sugar overconsumption, excessive fat intake and consumption of red meat and processed meat.

Discussion of the meaning of these results

Deaths from heart attacks and strokes

We know for some time that high sugar and high starchy food intake cause elevated triglycerides and elevated LDL cholesterol. This leads to hardening of the arteries and eventually to strokes and heart attacks.

High sodium intake

Sodium intake of more than 2300 mg per day is considered high and can cause high blood pressure. heart attacks, strokes and aneurysms.

Eating not enough fruit

If you eat too little fruit, your system does not get enough vitamin C and other vitamins. Heart disease, cancer and anemia could develop from that.

Eating not enough vegetables

People who do not eat enough vegetables do not have enough antioxidants that protect them from free radicals. Free radicals are unstable chemicals that attack cells and DNA. Mutated cells can cause cancer. If you eat too little vegetables, you are at a higher risk of getting cancer. But there is another aspect of vegetables: phytonutrients protect from hardening of the arteries and blockages of heart and brain vessels. When someone does not eat enough vegetables, the risk for heart attacks and strokes is higher. Eating vegetables also protects you from diabetes and keeps the blood sugar more stable.

Not eating enough whole grain

Whole grain was identified as missing in a lot of people’s diet. When you incorporate whole grains into your food, you reduce the risk of cardiovascular disease, hypertension, type 2 diabetes, colon cancer, and obesity.

There are vitamins, minerals, dietary fiber and lignans in whole grain. Other nutrients are beta-glucan, several phytochemicals, phytosterols, phytin, and sphingolipids. All of these are necessary to maintain good health.

Low omega-3 fatty acid consumption

Omega-3 fatty acids are important for healthy skin, brain development (neurodevelopment of children) and prevention of heart attacks. Omega-3 fatty acids reduce the risk of cancer because of their anti-inflammatory action and inhibition of cell growth factors. In one study rectal cancer showed a 21% reduction comparing the highest omega-3 fatty acid intake to the lowest intake of omega-3 fatty acids. Colon cancer showed no effect to omega-3 consumption, but breast cancer showed a reduction with omega-3 fatty acid supplementation. Researchers showed that omega-3 fatty acid supplementation can slow down dementia and Alzheimer’s disease. Protein deposits called amyloids were found less in the brain of patients with omega-3 fatty acid supplementation; in addition the brain volume was preserved more with the omega-3 supplement. Low omega-3 fatty acid consumption also has a detrimental effect on macular degeneration of the eyes and on joint pains of rheumatoid arthritis patients.

The Foods That Are Killing Us

The Foods That Are Killing Us

Conclusion

I have reviewed a global health study that described various risks that led to deaths from different diseases. It was noticeable that death and disability rates varied significantly according to different countries. The authors also looked into food habits and could pinpoint certain food deficiencies that caused diseases that prematurely disabled or killed people. I have described the various one-sided food habits that led to specific diseases.

What we should all learn from this complicated study is that we all can strive to eat more balanced meals. You want to eat a low sodium diet, eat enough fruit and vegetables, to which you add some nuts. Eat enough whole grains and add omega-3 fatty acids. This way the risk of getting cancer, cardiovascular diseases or other problems can be significantly reduced.

Live The Life That We Evolved For

A review article at CNN by a psychiatrist recommends that we live the life that we evolved for. Dr. Arash Javanbakht, an assistant professor of psychiatry at Wayne State University in Detroit, MI explains that man lived on this planet only since 200,000 years. But it takes about 1 million years for evolutionary changes to take place. As a result of this we tend to still behave in our lives the way we may have reacted 10,000 years ago. It is useful to think back of us being hunters and gatherers.

Anxiety, an ancient emotion

Anxiety, for instance, is an emotion that goes far back to 10,000 years ago when humans had to be part of the tribe. If an opposite tribe was fighting them chances were high that they could get killed. Even if your own tribe did no longer like you, there was a strong possibility that you were driven out or killed. This left us with an inheritance going back many millennia of anxiety. In modern life though it is the boss who does not like something you did. It could be a deadline for a school or college project that makes us anxious or some political news. The reasons have changed, but anxiety is still there!

Live the life that we evolved for: assess what we eat

Food was very scarce 10,000 years ago. When the tribe finally caught some prey, there was a feast where fatty food, meat, vegetables, fruit, nuts and seeds were eaten. Refined sugars were not available. You did not know when the next time would come where you had ample food. Today we still behave this way: we eat what we can and eat some more. The only problem is that there is no longer the pattern of famine orfeast. Instead there is easy access to the fridge with all kinds of food. We also have access to fast food places. And we drink sodas, eat candies and other sweets. Eventually we end up fat and fatigued.

Live the life that we evolved for: which way do we move?

Our ancestors had to run and walk many miles a day to find food. They may have been attacked by wild animals and had to flee. They also needed to chase a prey for food. Constant movement was the order of the day. What are we doing today? We did not evolve to step into a car and drive to work. We also did not evolve to sit at a desk from 9AM to 5PM. In the evening we sit in front of the TV or lie on a couch eating munchies and drinking beer.

Our modern life

It is no wonder that we gain weight, that our heart and lungs do not get conditioned, and that our muscles are a pile of mush. We need to think back what our bodies were built to do. Perhaps a long walk would be healthier than sitting all the time. Some of us do not mind to visit a gym daily and build an exercise routine into the day. This mimics the activities of the hunter/gatherers and is a lot better for our bodies.

Live the life that we evolved for: sleep problems

Many people today have problems to fall asleep. The sun had 100% control of the diurnal rhythm in the past. Now we have artificial lightning, blue light from TV’s, computer screens and iPhones. We are constantly getting stimulated. In addition, the stories we read or see on TV get us excited, so that the stress hormone, cortisol is released and melatonin, the sleeping hormone gets suppressed. Taken all this together, it is not really a wonder we have problems sleeping. Relaxation methods can help us to tone down before we go to sleep. You may want to meditate, do self-hypnosis, practice some yoga or just lie still and relax, clearing your mind, and more importantly switch the TV off and put the computer on “sleep”. Sleep for you comes easier this way.

Live the life that we evolved for: our fears

10,000 years ago fear was a normal part of our lives. There were predators you had to fear. There were tribal wars where you had to fight for your survival. You had to fear starvation. The fight/flight response was a reality. Compare this to our lives now. We may fear an exam, a meeting at work or agonize what to wear for a party. We have no real existential fears unless you live in a war zone. Many people may feel that they do not have enough fear in their lives, so they get drawn to horror and mystery stories, computer games, haunted houses etc. But this is fodder for anxiety!

Live the life that we evolved for: how to feel better

When we adopt a pet, let’s say a dog, we understand that it needs food, exercise, love and sleep. But when it comes to the human animal in us, we find it hard to understand that we need that too. In fact, we need to live the life that we evolved for. We need some form of exercise all the time, because that is what we were meant to do 10,000 years ago and our bodies are still built for that. When you walk the dog, you may make new friends or even a date. If you go to the gym, you realize that your muscles work better and begin to make your body fitter. You will also feel better about yourself. You appreciate that your mood is lifting, and you feel the increased energy and strength.

Dr. Arash Javanbakht said about the bottom line:

“If we treated our body the way responsible dog owners treated their dog, we would live a much happier life.”

Live The Life That We Evolved For

Live The Life That We Evolved For

Conclusion

It takes people 1 million years for evolutionary changes. We do not change our behavior fast. Dr. Arash Javanbakht, an assistant professor of psychiatry at Wayne State University in Detroit, MI compared our lives now with the lives of the hunters/gatherers in the past. People ate fatty food, meat, vegetables, fruit, nuts and seeds when a prey was hunted. But then there was an episode of fasting. People then had to walk and run all day long to catch some food again or they had to run to escape from a predator. Nowadays we use cars for transportation, use the elevator to get upstairs and walk from the table at home to the TV set. If we do not move enough and we eat the wrong foods, we do not turn fit but we turn fat.

Our modern lives

We also use LED lights from TV’s, computers, iPhones and tablets that interfere with our diurnal hormone rhythm. It is not about going back to sending smoke signals, but it is all about setting limits and when to stop and disengage from social media and the phone. Not setting limits is part of why we have problems to sleep. Stress can also be a factor of insomnia. Dr. Javanbakht says that we need to relearn how our bodies were built. We need proper nutrition without high-energy carbs. In addition we need regular exercise that will help us to relax and feel more energy. Anxieties will lift and we will feel better about ourselves.
