About Aging and a Prolonged Life

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.”

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.

Eating the right Food Determines your Health

By | Cancer, diet, exercise, food, Health, heart attack, Mortality, Nutrition, Prevention, sleep, sugar

CNN had an interview with Dr. Leana Wen about the fact that eating the right food determines your health. Dr. Wen is a wellness expert, an emergency physician and adjunct associate professor at George Washington University.

How much does the quality of food we eat influence our health?

There are detailed studies that showed the following effects of healthy food on our lives.

  • If you eat a diet consisting of more vegetables, fruits, whole grains and nuts, the following will happen. You could exceed the age of controls eating unhealthy food by 10 to 13 years.

Specifically, a woman starting such a diet at age 20 would add 10 years to her life, when starting at age 60 she could add 8 years to her life. For men starting this diet at age 20 would allow him to gain 13 years, when starting at age 60 he would add 9 years to his life.

Additional healthy food studies

  • A 2023 Nature study found that men can add 10.8 years, women 10.4 years by switching their diets. This switch was from unhealthy diets to a longevity diet with more whole grains. In addition, the healthy diet contained more nuts and fruits and less sugar-sweetened beverages and processed meats.
  • Another 2023 study from the Jama network followed over 100,000 people for more than 30 years. There was an association between adopting healthy eating patterns and a reduction in early mortality. People on a healthy diet reduced their risk of early death by 20%! The study also noticed that people who ate more whole grains, fruits, vegetables, nuts and legumes had fewer other diseases. They were less likely to die from cancer, cardiovascular illness and respiratory and neurodegenerative disease. These were important findings. 

What kinds of food make you live longer?

Dr. Wen stated clearly that it is only minimally processed, whole food that allows a person to live longer. The highly processed foods like processed meats, sausages, cakes and cookies are a “no go”. They are the ones that cost lives from heart attacks, strokes and cancer. On the other hand, leafy green vegetables, fresh fruits and whole grains associate with significantly reduced mortality. Fish contains omega-3 fatty acids, which reduce heart disease and dementia. It is also a good source of protein. So, stay away from hot dogs and chicken nuggets, instead enjoy salmon fillet or roasted chicken.

Foods that you need less of

Avoid sugar sweetened sodas and energy drinks, as they elevate cholesterol levels and cause heart attacks. Next, stay away from ultra-processed foods like chips and candies. In one study with more than 11,000 participants people who ate a lot of ultra-processed foods had a 31% higher risk of mortality.

With what do you replace junk food?

Here are a couple of examples. Somebody who used to drink a lot of sodas can replace them with water, sparkling water, flavored water or lemon juice, sweetened with stevia. Instead of snacking on ultraprocessed foods like chips, candies or pretzels eat nuts instead. Look at the list of ingredients before you buy anything in the grocery store. If there is a long list of ingredients including chemicals, this is ultraprocessed food. Replace it with minimally processed foods with only a few items on the ingredient list.

Other advice for health and longevity

  1. If possible, eat three meals a day (breakfast, lunch and dinner). Stop eating 2 hours before bedtime to allow your guts to digest the food you previously ate. This avoids heart burn and interference with your sleep.
  2. Exercise regularly. Studies showed that 150 minutes of vigorous exercise per week reduced mortality by 23%.
  3. Take care of stress in your life. Cherish your social life and socialize; it is important for longevity. See your doctor regularly to take care of any medical problems you may have.
  4. Watch your sleep habits. Many studies have shown that adults need 7 to 8 hours of sleep. Sleep restores your hormone glands, gets them ready for the next day, but it is also important for longevity.
  5. Keep your body mass index (BMI) between 21.0 and 24.0. Personally, I keep my BMI between 21.0 and 22.0. Any extra pounds of fat merely lead to elevated cholesterol and triglycerides. Eventually this leads to heart attacks and strokes, but also to diabetes.
Eating the right Food Determines your Health

Eating the right Food Determines your Health

Conclusion

A recent article in CNN described that eating the right food determines your health. One study said that you should eat a diet consisting of more vegetables, fruits, whole grains and nuts. Doing this increases your life expectation by 10 to 13 years compared to controls who ate unhealthy food. It is only minimally processed, whole food that allows a person to live longer. You must eliminate ultraprocessed food. This means you should not consume sausages, fries, chips, pretzels and other overprocessed foods. Instead, eat leafy green vegetables, fresh fruits and whole grains that associate with significantly reduced mortality. Yes, eating the right food determines your health.

Allergies to Red Meat after a Tick Bite

By | Allergies, anaphylactic reaction, food, Prevention, red meat

A new disease has arrived, allergies to red meat after a tick bite. This condition has surfaced in Australia and in the southeast of the US. It is linked to the bite by a lone star tick. Researchers determined that alpha-gal, which is galactose-α-1,3-galactose from the saliva of the tick is responsible for causing an allergy. Meat from mammals also contains alpha-gal. Due to a cross reaction between a lone star tick bite and alpha-gal in beef and other meats a person can develop a sensitivity to alpha-gal. This has the name alpha-gal syndrome (AGS). Between 2010 and 2022 the CDC recorded about 110,000 suspected cases of AGS in the US.

Symptoms of alpha-gal syndrome

A person who was previously sensitized by a lone star tick bite often only gets symptomatic after eating beef. The symptoms are hives, a skin rash, nausea or vomiting, heartburn or indigestion and diarrhea. Other symptoms could be a cough, shortness of breath, difficulty breathing or a drop in blood pressure. Some patients develop swelling of the lips, throat, tongue, or eye lids. Others complain of dizziness, faintness or severe stomach pains. These symptoms usually develop 2 to 6 hours after eating a meal with beef or dairy products. The person who was previously bitten by a lone star tick was sensitized following this encounter and produced specific antibodies against alpha-gal. The second encounter of the body from ingested alpha-gal containing food is the reason why the allergic reaction takes place. The more alpha-gal is ingested by different foods that contain it, the more severe the allergic reaction becomes.

Diagnostic tests for alpha-gal sensitivity

Allergists have the following tests available to them to check your immune system.

  • One test is called the alpha-gal U953 immunocap, a blood test.
  • The mammalian meats immunocap (Beef, Lamb, Mutton, Pork and Rabbit are available) shows specific antibodies as a result of exposure to these meats.
  • In severe cases of alpha-gal sensitivity blood tests for a mast cell tryptase level may also be necessary. This test can distinguish between a higher or lower risk of alpha-gel sensitivity. Tryptase is an enzyme, which is higher in people with mastocytosis. There is often an elevation of tryptase in patients who have allergies to both insect bites and tick bites.

Foods that contain alpha-gal

The Australasian Society of Clinical Immunology and Allergy describes in great detail what foods contain alpha-gal and what not. The main culprit in developing alpha-gal syndrome is mammalian meat. The most popular among these is beef, but veal, pork, lamb, buffalo, venison, rabbit and guinea pig also belong into this category. Other meats are deli meats like bacon, ham, salami, silverside, chorizo, prosciutto and others. When a person reacts to eating one or more of these items, we are dealing with a cross reaction. It is between the alpha-gal from the original tick bite and alpha-gal from the meat the person ingested.

There are more obscure mammalian meats that contain alpha-gal: whale, dolphin, seal, goat, kangaroo, wallaby and possum. But gelatin products and fats from mammals also contain alpha-gal.

What foods do not contain alpha-gal?

The following foods are OK to eat for people with alpha-gal sensitivity: chicken, mollusks, crustaceans, turkey, quail, goose, fish, duck, eggs, legumes, lentils and soy products (tofu, tempeh). According to the allergy.org website, you have to be careful about jams, soups and gravies, as merchants often mix gelatines into their products. Stay away from energy drinks with taurine, sausages (even chicken sausage) and cheese spread. Avoid rennet, jelly-based lollies, mousses and desserts. All of them contain alpha-gal.

Treatment for alpha-gal syndrome

There is no known treatment for sensitivity to alpha-gal. However, experience has taught allergists that strict avoidance of alpha-gal in food improves the symptoms. After about 3 to 4 years of a strict diet that excludes alpha-gal many patients are no longer sensitive to alpha-gal and can tolerate a certain amount of alpha-gal in their diet. But others continue to be sensitive to alpha-gal. They have to adhere to strict avoidance of alpha-gal in food and stay away from tick bites.

Allergies to Red Meat after a Tick Bite

Allergies to Red Meat after a Tick Bite

Conclusion

A new condition, alpha-gal syndrome has joined the rare, but important group of new diseases. It is a sensitivity to a sugar, called galactose-α-1,3-galactose, or alpha-gal. It is present in the mouth and saliva of the lone-star tick in the US and Australia. A bite from this tick can be the first sensitizer in a human. But unfortunately, alpha-gal is also present in many foods as mentioned in detail above. Repeated exposure to alpha-gal regardless of the origin causes hypersensitivity, which can get life-threatening. There is no treatment for this condition other than to adopt a very meticulous avoidance of alpha-gal in the diet. After 3 to 4 years of such a diet the hypersensitivity to alpha-gel disappears in many, but not in all patients. When the hypersensitivity persists, the patient has to continue with the alpha-gal avoidance diet.

What Electronic Cigarettes Do to You

By | e-cigarettes, heart attack, Lung Disease, Prevention

A review paper of Canadian researchers showed what electronic cigarettes do to you. They can be an effective smoking cessation aid for motivated smokers who eventually want to quit. But when people continue to inhale electronic cigarettes, their use can cause heart attacks, strokes, high blood pressure and increased heart rates. With regard to the lungs electronic cigarettes can cause vaping-associated lung disease, obstructive pulmonary disease, asthma and chronic cough. A literature review showed that e-cigarettes are less harmful to the heart and the lungs than smoking combustible cigarettes.

Increased use of e-cigarettes in younger people

In Canada the 2017 Canadian Tobacco, Alcohol, and Drugs Survey, which included all ages, found that 15.4% tried e-cigarettes. But among adolescents between 15 to 19 years old 22.8% were using e-cigarettes. For young adults aged 20 to 24 the figure of e-cigarette users was 29.3%. In addition, there was a significant increase of Canadian adolescents aged 16 to 19 from 29.3% in 2017 to 37.0% in 2018. Data from the US shows similar trends. E-cigarette use among US high school students increased from 11.7% in 2017 to 27.5% in 2019.

Some facts about e-cigarettes, cigarette smoking and smoking cessation

  • First, researchers noted that the smoking of e-cigarettes has a 3.62-fold risk of leading to subsequent cigarette smoking.
  • Second, a UK study found that when people used e-cigarettes for smoking cessation, 80% of the e-cigarette group were still smoking e-cigarettes after 1 year. In contrast, only 9% of those who used traditional nicotine replacement therapy (Nicorette etc.) to quit smoking were still using nicotine replacement after 1 year.
  • One study compared heart attack rates in a group of regular cigarette smokers and compared this to e-cigarette smokers. Cigarette smokers had a 2.72-fold higher heart attack rate than non-smokers, while e-cigarette smokers had a 1.79-fold heart attack rate compared to non-smokers.

Effect of e-cigarette use on heart and lung disease

Several studies looked at the relationship between e-cigarette use, heart attacks and strokes. There was a 1.4-fold higher incidence of coronary artery disease in e-cigarette smokers in comparison to non-smokers. The e-smokers had a 1.71-fold higher stroke incidence and 1.59-fold higher heart attack rates. In a large metaanalysis done with e-cigarette smokers, researchers noted the following facts: Electronic cigarette smokers were compared to non-smokers. Researchers noted a 2.27-fold increase of the heart attack rates in e-cigarette smokers. There was a 2-fold elevation of the systolic and diastolic blood pressure in e-cigarette smokers.

Switching from cigarette smoking to e-cigarettes

Patients who switched from tobacco smoking to chronic electronic cigarette use had a 7-fold reduction of their systolic blood pressure and a 3.65-fold reduction of their diastolic blood pressure. The researchers concluded that switching from cigarette smoking to e-cigarettes had some merit in terms of risk reduction for cardiovascular disease. But the final judgment on this is still pending. Certainly, quitting entirely from cigarette smoking is the best choice. I reported previously that e-cigarette smokers find it difficult to quit completely and if they smoke conventional cigarettes to stop that.

Effect of e-cigarettes on lungs

In addition to cardiovascular effects there is a direct effect from e-cigarette smoking on the bronchial tubes and the lungs. The vaped substances from e-cigarettes contain a lot of noxious gases that irritate the lining of the respiratory tract. This syndrome is called EVALI (electronic vaping associated lung illness). In 2019 and 2020 there was a rush of EVALI cases in the US with 2807 hospitalizations and 68 deaths. In Canada there were 19 cases of EVALI, 15 hospital admissions, and no deaths. Patients with EVALI have problems breathing, they cough and they have chest pain. Researchers suspect that vitamin E acetate and tetrahydrocannabinol are the major culprits that cause EVALI. But at this time there is no definite proof for that.

Poor quality of vaping fluid from the black market

These substances are not present in commercial e-cigarettes, but when you buy vaping fluid on the black market, it is often mixed in. Prolonged use of e-cigarettes can cause changes on spirometry, such as chronic obstructive pulmonary disease (COPD). Chronic use of e-cigarettes may cause premature onset of COPD.

What Electronic Cigarettes Do to You

What Electronic Cigarettes Do to You

Conclusion

E-cigarette use is increasing at an alarming rate among youths and persons who never smoked. The emerging evidence from researchers showed that there is a risk when you expose yourself to the smoke of e-cigarettes. There is an association of both heart disease and respiratory disease to e-cigarette smoking, but the risk is less than with exposure to regular cigarette smoke. Some researchers think that a switch from cigarette smoking to e-cigarettes could provide a viable harm reduction strategy for some smokers. But unfortunately, many continue to smoke e-cigarettes instead of quitting altogether. And in this case the risks for heart disease and lung disease remain!

Immune System Responses against Covid-19 or anti-Covid Vaccination

By | immune system, Infectious Disease, Prevention, vaccinations

This article is about immune responses against Covid-19 or anti-Covid vaccination.

Investigations of the immune system showed that people who had Covid-19 and subsequently were vaccinated had an immune response that lasted for at least one year. In the following a discussion follows about the details why this is so.

The WHO confirmed more than 430 million cases of Covid-19 since the pandemic started. 4.9 billion people or 63.9% of the world population received at least one vaccination as of late February 2022.

How vaccination against Covid-19 works

The vaccine attacks the spike protein of the Covid-19 virus (SARS-CoV-2). The body produces antibodies through B cell activation. These are lymphocytes that originated from the bone marrow (hence B cells). They are capable of producing large amounts of antibodies that target the spike protein of the virus. It takes at least two vaccinations with the Pfizer vaccine to get a good antibody response. A booster vaccine brings the antibody titer even higher.

Cell-mediated response by killer T cells

When the virus enters a cell, the antibodies are no longer effective. Here the T killer cell comes into play. T killer cells are lymphocytes that were thymus processed (hence the name T cells) and activated by the vaccine. T killer cells function as a second line of defence. These immune cells specialize in detecting virus-infected cells. They immediately destroy these cells before the virus has a chance to replicate and shed more virus copies into the blood stream. It is the T cell response that prevents hospitalizations and deaths. Media coverage misled the public to believe that the bulk of the immune response would be from antibody production. However, the truth is that the T cell response is what is responsible for recognizing Covid-19 variants and why people survive Covid-19 with very little complications.

Long term immunity

When people had a Covid-19 infection the activated B cells that produced antibodies and the T killer cells get converted into memory cells. With a re-infection the memory cells can reactivate themselves to turn again into active B cells producing antibodies and T killer cells. The key for immunity with multiple vaccinations is also the memory cell pool. Those with two Pfizer vaccinations and a booster vaccine are much more immune to Covid-19 than those who only received one or two vaccinations.

Waning immunity

Following an infection with Covid-19 the immunity comes to a peak at 3 months after the start of the infection. The CDC said that people who are 90 days post-infection do not require a quarantine when they meet someone with an active Covid infection. By about 6 months immunity is declining. This is also true for people after double vaccination and a booster vaccine.

Hybrid immunity

The immune response after either a natural infection with Covid or following vaccinations with anti-Covid vaccines lasts only about 6 months. On the other hand, scientists observed that people recovering from Covid infections who subsequently received an anti-Covid vaccine just once had a very strong immune response that lasts for over a year. This is called hybrid immunity. This type of immune response triggers a very strong antibody response that is lasting longer. Immunologists are now researching whether the hybrid immunity is achievable with an improvement to vaccines. Results of this will not be available for several years.

Immune System Responses against Covid-19 or anti-Covid Vaccination

Immune System Responses against Covid-19 or anti-Covid Vaccination

Conclusion

The immune response to Covid lasts for about 6 months; the same is true for the immune response after a vaccination. But when a person comes down with Covid and he or she receives a vaccination one month later, the immune response lasts for over one year. Scientists call this hybrid immunity. At this point experts recommend to have a booster vaccine every 6 months. But immunologists are researching for ways to incorporate the mechanisms of hybrid immunity into vaccines, which likely will not be available for several years.

Avoid deliberate exposure to Covid-19

Some persons who read about the response after a Covid infection and a vaccination misinterpreted this. They took this as an “invitation” to expose themselves to the virus in the hope to boost their immunity. However, a Covid infection remains an illness with potentially serious consequences. There is no way to predict whether the course of an infection will be mild or extremely severe. In addition, a significant number of patients come down with “long covid” and struggle with breathing problems, lack of energy and more. Covid is still here, and our best protection remains the full vaccination including boosters and hygienic measures. This involves masks, frequent hand-washing and disinfection of surfaces in daily life.

World Suicide Prevention Day is on September 10

By | alcohol, Anxiety, depression, Pain, Prevention, stress, Substance abuse, suicide

A CNN article points out that world suicide prevention day is on September 10.

Some statistics regarding suicides

According to the WHO more than 700,000 People die from suicide every year.

In the US suicide rates have risen between 1999 and 2018. President Joe Biden stated: “In 2019, suicide was the 10th leading cause of death in the United States, and the second leading cause of death for young people between the ages of 10 and 34.”

This was further underlined by a study from the CDC. It pointed out the emergency room visits started to climb in May 2020 for attempted suicide in youth. The CDC stated: “The mean weekly number of these visits was 26.2% higher during summer 2020 and 50.6% higher during winter 2021 compared with the corresponding periods in 2019”.

Triggering factors that make people commit suicide

Suicidal thoughts start when a vulnerable person encounters stressful events. The life situation can become so painful that in their way of thinking suicide is the only way to stop the pain. There are huge differences of opinions: what may be meaningless to one person, may feel devastating to another.

Common triggering factors are as follows.

  • Illness and physical discomfort
  • Conflicts with family or friends
  • Illness of family members
  • Death of family member or friend
  • Loneliness

In a study 50% expressed two of these 5 triggers, 37.5% expressed one of the 5 triggers. 12.5% expressed three of the 5 triggers.

With the Covid-19 epidemic there are new pressures on people. They cannot freely move around or travel. He/she may have lost a friend or relative to Covid. And people may be anxious about their own survival. I described this here before.

Biochemical changes in the brain with depression

In the past low serotonin levels in the brain were thought to be the main cause of depression. But researchers realized later those medications that increased serotonin levels did not always help depression. They found that dopamine and norepinephrine are also important brain transmitters that play a role in depression. When dopamine levels are low, depression occurs. Similarly, when norepinephrine is low, the patient can develop depression. On the other hand, in bipolar disorder the brain produces too much norepinephrine, which causes manic episodes. https://www.verywellmind.com/the-chemistry-of-depression-1065137 The physician needs to take a thorough history and note from that which brain transmitter system would be mainly affected. This helps the physician later to decide which antidepressant to choose from to rebalance the brain transmitters.

How to detect stress signals

There are a number of risk factors, which the CDC has outlined, for which the health professional or a family member wants to look in order to assess the suicide risk.

Does the patient have a history?

People with a mood or anxiety disorder, or with an alcohol or substance abuse disorder are at a higher risk of developing depression and suicide.

Did the person experience a loss?

A loss can be a death in the family, a loss of a job or the loss of an important person in a relationship. This is particularly bad when there is social isolation and a lack of support. With Covid-19 millions of people have suffered the loss of a job, social isolation and having to quarantine.

Is it easy for the distressed person to get a gun?

Firearms are a common means for people to kill themselves. When there is easy access to a gun, there is a high probability that the person uses it in times of distress.

History of previous suicide attempt

When a person attempted to commit suicide, but failed, there is a higher risk for them to repeat a suicide attempt and succeed. Also, there is a copycat phenomenon when the news comes out that a famous personality committed suicide. For instance, when the comedian Robin Williams committed suicide in 2014 there was a 10% rise in suicides in the following months all over the US.

Belief system that honours personal sacrifice

Some religious or cultural groups consider suicide a noble solution to a personal dilemma.

A person from this background is at a much higher risk to commit suicide.

Warning signs of pending suicide attempt

There are a number warning signs that point to a higher risk of possibly planning suicide.

  • A person may talk about wanting to die or kill themselves.
  • Searching online for ways to kill oneself or buying a gun.
  • Feeling trapped or feeling unbearable pain.
  • Talking about feeling hopeless and having no reason to live.
  • Stating that they feel they are a burden to others.
  • Drinking more alcohol and using more drugs.
  • Acting agitated or anxious. Reckless behavior.
  • A person withdrawing or isolating themselves.
  • A person sleeping too much or too little.
  • Extreme mood swings.
  • Talking about seeking revenge or showing rage.

These are all red flags that should alarm you to ask for help. Not all of these alarm signs are present all the time with people who are considering to attempt suicide. When you have suicidal thoughts in the US, call the National Suicide Prevention Lifeline at 800-273-8255. For Spanish crisis support call: 888-628-9454.

World Suicide Prevention Day is on September 10

World Suicide Prevention Day is on September 10

Conclusion

World suicide prevention day is on September 10. This reminds us every year that suicide is a colossal problem of society. Stress, loss of health, losing a loved one, a broken marriage and financial loss can all contribute to depression. If patients with mental distress do not receive timely intervention and treatment, the life situation can become so painful that in the patient’s way of thinking suicide is the only way to stop the pain. The key is for the loved ones in the circle of friends to pay attention to the warning signs and bring the suicidal person to the attention of the psychiatric health professionals. Sometimes an in-patient admission to a psychiatric facility may be required to interrupt the negative thinking pattern. Ignoring the warning signs can have devastating consequences. Prevention is the only way to avoid suicide.

Pollen Allergies Make Covid-19 Infection Rates Worse

By | Allergies, Asthma, immune system, Infectious Disease, Inflammation, Prevention

A recent study showed that pollen allergies make Covid-19 infection rates worse. This was published in the Proceedings of the National Academy of Sciences (PNAS) in March 2021.

The study determined that airborne pollen exposure enhances susceptibility to respiratory viral infections. Specifically, this includes SARS-CoV-2 infections as well. There were 130 test sites in 31 countries across 5 continents where measurements were made. Pollen concentration, air humidity and temperature, population density and lockdown effects on Covid-19 figures were measured. In countries with high pollen counts, high humidity and higher temperatures the Covid-19 rates were up to 44% higher than in countries with low pollen counts and colder climates.

PNAS study in more detail

In the following I am discussing the PNAS study in more detail. The SARS-CoV virus from the SARS epidemic in 2002 and the present SARS-CoV-2 virus are both capable to suppress the body’s interferon response to either virus. Additionally, there are intracellular proteins with the name “inflammasomes”, which the SARS-CoV-2 virus activates. With excessive activation this causes a cytokine storm, where inflammation spreads through the whole body. In the blood this leads to disseminated coagulopathy with multi organ failures. In the lungs severe acute respiratory syndrome occurs with severe viral pneumonia. On average mortality is 3.4%.

Tree and weed pollen can weaken the immune response

A study from South Korea examined what happens with exposure in asthmatic and allergic school-aged children to tree and weed pollen. https://www.sciencedirect.com/science/article/pii/S0091674919311856.

Allergic reactions make allergic children more prone to rhinovirus infections by reducing interferon in the blood. In addition, allergic reactions stimulate inflammasomes. When the SARS-CoV-2 virus affects an allergic child, both interferon depletion and excessive inflammasome activation make Covid-19 much more severe than in a child without allergies.

Warm spell in the Northern Hemisphere

On March 12, 2020 the WHO announced the Covid-19 pandemic when over 33% of the world’s countries were affected by the SARS-CoV-2 virus. However, at the same time there was a large-scale warm spell across the Northern Hemisphere with tree pollens being distributed across the same regions. This resulted in an exponential increase of Covid-19 cases. The researchers determined that the rates of Covid-19 infections were highest in areas where there was a high tree pollen count, crowding of people and high humidity/temperatures. The researchers used data from 248 airborne pollen monitoring sites in 31 countries. The highest exponential growth rates of Covid-19 occurred in the countries with the highest pollen counts. 6 out of 8 countries studied with regard to high pollen counts showed a significant correlation with regard to Covid-19 infections in excess to just person-to person virus transmission.

Population density and lockdown affecting daily SARS-CoV-2 virus rate

Some countries had a complete lockdown when rates of infection were high. This reduced transmission of the SARS-CoV-2 virus by 50%. Those countries with only a partial lockdown still experienced a significant reduction of infection rates. Rural areas had significantly less daily SARS-CoV-2 virus rates compared to very densely populated cities.

The researchers observed the following:

  • There was a lag effect of 4 days between the increase of pollen concentration in the air and infection increase with the SARS-CoV-2 virus
  • Pollens in the air caused infection rates of SARS-CoV-2 to rise by 10 to 30%, but in some high pollen areas even up to 44%.
  • Lockdowns reduced infection rates of SARS-CoV-2 by 50%
  • Higher environmental temperatures and higher humidity of the air also increased infection rates of SARS-CoV-2, although this may have occurred indirectly by increasing the pollen count in the air

Discussion

  1. The authors added a thorough discussion of the multiple factors regarding the increase of the infection rate of Covid-19 in 2020. They pointed out that climatic factors, air pollutants, or pollen, often exert their effects at the same time. They quantitated the contribution of the pollen count in the air easily. In contrast, pollution and climatic factors were not predictable in their effects.
  2. The infection rate of the SARS-CoV-2 virus always lagged behind the increase in pollen count by 4 days. The researchers observed this in all those countries where increasing pollen counts were a significant factor.
  3. The epithelial lining of the nasal cavity is the target of inhaled pollen. The researchers cited several publications regarding reduced interferon production as a result of exposure to pollens in the nasal mucous membranes. This leaves the immune system with a weakness, which the SARS-CoV-2 virus exploits. Recently specialists discussed the use of intravenous interferon to interrupt the cytokine storm caused by the SARS-CoV-2 virus.
Pollen Allergies Make Covid-19 Infection Rates Worse

Pollen Allergies Make Covid-19 Infection Rates Worse

Conclusion

In a recent publication researchers showed that pollen allergies make Covid-19 infection rates worse. The investigators had 130 test sites in 31 countries across 5 continents where they took measurements. They measured pollen concentration, air humidity, temperature, population density and lockdown effects on Covid-19 figures. In March of 2020 there was a warming trend in the Northern Hemisphere. This caused pollen counts to significantly rise in many countries. The result was that the mucous membranes in the nasal cavity weakened. This made it easier for the SARS-CoV-2 virus to multiply and invade. A lag period of 4 days occurred between the rise of the pollen count and the start of SARS-CoV-2 infection. The authors recommend that those who react to pollens in the air should wear pollen filtering masks in the spring season. This minimizes the danger of getting viral infections including SARS-CoV-2 infections following pollen exposure.

Key Factors for Centenarians

By | alcohol, Alzheimer’s disease, Cancer, Cardiovascular disease, Diabetes, diet, exercise, fasting mimicking diet, fish oil, food, heart attack, Mortality, olive oil, omega-3 fatty acids, Prevention, Processed food, stress, Stress management, Stroke

A study from Washington State University (WSU) showed some of the key factors for centenarians to survive. The publication of the study goes back to June 17, 2020. In general, it was common knowledge that genetics plays a role in 25% to 35% of centenarians for their survival. That is to say, the remainder is the result of lifestyle factors. It is important to realize that the environmental factors play a significant role in the survival of centenarians, said Rajan Bhardwaj, a second-year WSU medical student. He and his research team determined what allowed centenarians to reach an age of 100 or above. Briefly, they identified the following factors that were necessary.

Three factors identified by the Washington State University study

  • walkability of the neighbourhood, which encourages regular exercising
  • belonging to the higher socioeconomic class
  • a high percentage of working population in the neighborhood (a mixed population) was also important

In the discussion the authors of the WSU study said that “blue zones” of centenarians had been mentioned before in the literature. To clarify, these are areas in the world where more than the average of centenarians live. Dan Buettner used the term “blue zones” in a National Geographic article about where centenarians were located.

The blue zones

He wrote a book about the location of the 5 blue zones. Notably, they are located in Sardinia (Italy), the islands of Okinawa and a group of Seven Day Adventists in Loma Linda. California. In addition, the Nicoya Peninsula of Costa Rica, and the island of Icaria, Greece complete the 5 blue zones. Specifically, Dan Buettner described the following characteristics of the lifestyle of centenarians.

  • They engage in regular physical activity
  • Mostly eating a plant-based diet including legumes
  • Calorie intake is moderate
  • Moderate intake of alcohol, mostly wine
  • Having a purpose in life
  • Engaged in family life
  • Having an active spiritual life
  • Reducing stress
  • Engaged in social life

Other attributes of centenarians

Dr. Thierry Hertoghe gave a presentation in Las Vegas on Dec. 14, 2019 where he stated that centenarians are positive thinkers. This was at the 27th Annual World Congress on Anti-Aging Medicine. In particular, the topic of his talk was “Positive Psychological Attitudes of Centenarians “. Dr. Hertoghe is an endocrinologist in Belgium. He took an interest in people above the age of 100. These people, he felt, are special people with a very optimistic outlook on life. Dr. Hertoghe went on to say that centenarians have a will to live. Indeed, they adapt to changes; they have a sense of purpose, and they stay active.

More positive attributes of centenarians

Other psychological features, by the same token, show that they have a positive mood and they avoid stress and anxiety. Another key point is that they have self-determination. It must be remembered also that they are very sociable, have close family ties, love their relationships and often have a strong religious faith. In addition, there is a connection between their basic values, beliefs and spirituality. Truly, centenarians insist on their freedom and they have a feeling of youth. For one thing, centenarians have their own centenarian spirit where they can feel young or old.

In the following I am reviewing some of the details that Dr. Hertoghe gave.

The will to live

For one thing, it takes courage to grow old, and all centenarians have this. They say “Life is worth living”. Essentially, they have a certain resiliency in a world that has an obsession about youth. Despite negative experiences they had to overcome they do not give up and they enjoy life as much as they can. A Finnish study examined 400 individuals aged 75-90 and followed them for 10 years. Group 1 who wished to live less than 5 years had a mortality rate of 68%. Group 2 wished to live for 5-10 years. They had a mortality of 45.6%. The last group, group 3 wanted to live more than 10 years. Surprisingly, their mortality was only 33.3%. Be careful what you wish for!

Adaptability

In other words, this describes the capacity to overcome adversity and your ability to adjust. In a study of 7400 Chinese centenarians’ resilience to changes was measured with psychometric psychological tests. The majority of subjects did not qualify for being resilient. However, 9% of male centenarians and 6% of female centenarians had the resiliency where they qualified for high adaptability. This high resilience group had a 2%-4% lower mortality risk. They had a 36%-55% higher probability of not developing cognitive impairment. That is to say, they rated themselves to be in good health and having a “good life” satisfaction. These resilient centenarians had a 7%-12% higher probability of not developing a physical disability. In essence, these high resilient centenarians had no short-term health decline.

Remaining active

If a centenarian remains active and moves about several hours per day, the body functions are preserved. Anna Mary Robertson Moses who was known by her nickname “Grandma Moses” took up painting at age 78. She died at age 101 in 1961.

Positive emotions

One study of 54 Ashkenazi Jewish older adults (aged 98-107) compared those with positive emotions to those with negative emotions. The researchers noted that a positive attitude about life allowed centenarians to live longer.

A study involving 2282 Mexican Americans aged 65 to 99 showed that positive affect scores were a predictor for the following. Subjects with a high positive affect had a 52% lower probability of becoming physically disabled. They were 36% less likely than the negative controls to lose their walking speed. In addition, they were 47% less likely to die during the two-year observation period than their negative controls.

Nurses’ Health Study and Veterans Affairs Normative Aging Study

Two studies, the Nurses’ Health Study (NHS) and men from the Veterans Affairs Normative Aging Study measured optimism. The researchers found that those with the highest optimism scores had a 1.5-fold higher probability in women and 1.7-fold in men to survive to age 85. This was compared to a control with the lowest optimism scores. Dr. Hertoghe provided 19 more studies that showed the effects of positive emotions regarding long term survival. For brevity reasons I will not dwell on them here.

What is the centenarian spirit?

When people are older than 100 years, they often have a mix of humor and eccentricity; they express emotions openly and they are happy people. They accept the death of spouses, siblings and significant others.

By the way, humor has a strong predictive survivor value. In a study that researchers conducted over 15 years, there was a clear positive effect of humor regarding mortality. A sense of humor reduced the all-cause mortality by 48% in males. In women humor lowered mortality regarding cardiovascular disease by 73%. Humor reduced death due to infections in women by 83%. Men had a non-significant reduction of all‐cause mortality by 12% and a significant lower mortality due to infections by 74%. Dr. Hertoghe cited three more publications that showed the power of humor in reducing disease and disability.

The fasting mimicking diet helps you to reach a longer life

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

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

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

Key Factors for Centenarians

Key Factors for Centenarians

Conclusion

As we reviewed the factors that lead to longevity, we learnt that engaging in regular moderate exercise is one of the key factors. But belonging to the higher socioeconomic class and living in a mixed neighborhood with people from all walks of life is also important. We also reviewed the blue zones according to Dan Buettner. Mostly eating a plant-based diet including legumes with moderate calorie restriction prolongs your life. Add to this moderate intake of alcohol, mostly wine, and having a purpose in life. Augment this further with being engaged in family life, having an active spiritual life and reducing your stress level.

Living longer is a matter of fulfilling these longevity factors

With all of this you are on your way to become a centenarian. A review by Dr. Hertoghe in a lecture given at an Anti-Aging Conference in Las Vegas in 2019 added more criteria centenarians have. He provided references regarding the will to live, being adaptable, remaining active and harboring positive emotions. The more of these factors you can adopt, the longer you will live. At the same time, you will avoid getting diseases like heart attacks, strokes or cancer, which leads to a longer and healthier life.

Adequate Vitamin D Level Strengthens the Immune System

By | immune system, Infectious Disease, Inflammation, kidney disease, Lung Disease, Mortality, Prevention, Vitamins and supplements

The Covid-19 coronavirus crisis is teaching us that an adequate vitamin D level strengthens the immune system.

When we age, our resistance to infections weakens, but this may be because our immune system needs more vitamin D3. I have reviewed the super powers of vitamin D3 before in 2014. In the past the thought was that the human body would need only 400 IU of vitamin D3 every day to cure rickets. And these were the daily vitamin D3 recommendations from medical authorities for several decades. Gradually it became known that for cancer prevention, infection prevention, cardiovascular illness prevention and for diabetes prevention much higher doses of vitamin D3 were necessary. As pointed out in the previous link, almost 50% of the world population is deficient in vitamin D. This is due to a lack of exposure to sunlight and due to inadequate supplementation with vitamin D3.

History of vitamin D

Dr. Adolf Windaus received the Nobel prize for chemistry in 1928. It was to acknowledge “… his studies on the constitution of the sterols and their connection with vitamins”. His work involved the metabolism of vitamin D and the precursors of vitamin D.

Rickets

As the above link shows, rachitic children were treated since the mid 1800’s with cod liver oil and since the early 1900’s also with ultraviolet light. But we know now that 400 IU of vitamin D3 per day is just enough to cure rachitic children, but it is not enough to strengthen the immune system to fight influenza viruses or the Covid-19 coronavirus. I will discuss further below what vitamin D blood levels are important to achieve a healthy state of the immune system.

Adequate vitamin D level strengthens the immune system

The immune system is very complicated and consists of many cell types that interact with each other and the rest of the body. It is important to recognize that the innate immune system immediately inactivates intruding viruses. But the vitamin D blood concentration has to be high enough. The acquired immunity consists of antibodies that are produced by B cells. The antibodies were produced during prior infections that you have survived and you are now immune to. However, other antibodies that circulate in your blood may have originated from vaccines you received in the past (whooping cough, measles, tetanus, diphtheria etc.). With the Covid-19 coronavirus it is the innate immunity that plays the biggest role until a vaccine will be found in the future.

Vitamin D is a hormone

This 2013 paper explains that vitamin D is a hormone that stimulates its own vitamin D receptor. This is a nuclear receptor that has close relations to the cell DNA and can stimulate more than 900 polypeptides. They are messenger molecules that are involved in a variety of physiological functions. One of the key functions is the immune system. This link explains that T cells that have vitamin D receptors can develop into cytotoxic T cells (also known as “killer T cells”). They are important in fighting cancer, but also parasites.

The key is that the hormone vitamin D can release more than 100 polypeptides that have the power to fight virus attacks including the Covid-19 coronavirus.

Three mechanisms how vitamin D works against the virus

The researchers outlined 3 mechanisms of how vitamin D works:

  • Maintaining tight epithelial junctions making it more difficult for the Covid-19 coronavirus to penetrate.
  • “Killing enveloped viruses through induction of cathelicidin and defensins.” These powerful antiviral polypeptides can kill viruses that have invaded the blood stream within 1 to 2 days.
  • “…And reducing production of proinflammatory cytokines by the innate immune system, thereby reducing the risk of a cytokine storm leading to pneumonia.” It is people who get the viral pneumonia that are at a high risk of death. By bringing the blood level up to the higher range of normal, between 50 and 80 ng/mL, patients that have encountered Covid-19 coronavirus are more likely to survive.

Two polypeptides, cathelicidin and defensins

Again, I like to emphasize that it is not vitamin D that has a direct effect on the virus. It is two polypeptides, cathelicidin and defensins, which are powerful antiviral polypeptides, that are released by vitamin D.

They can kill viruses that have invaded the blood stream and can eliminate the cytokine storm. This all happens very fast, within only 1 to 2 days. But you have to have an adequate vitamin blood level for this to occur (about 50-80 ng/mL).

Sources of vitamin D

First of all, vitamin D is readily absorbed from food. But there are not many foods that contain enough vitamin D for the immune system. The ones that contain vitamin D are as follows:

  • “Fatty fish, like tuna, mackerel, and salmon.
  • Foods fortified with vitamin D, like some dairy products, orange juice, soy milk, and cereals.
  • Beef liver.
  • Cheese
  • Egg yolks. “

Sun induced amount of vitamin D

Secondly, vitamin D can be synthesized in the skin from exposure to sunlight. But for this to happen all the necessary enzymes need to be present.  This link explains that many older people above the age of 65 have low vitamin D blood levels because of a lack of sun exposure and a lack of cutaneous synthesis because of enzyme issues.

Vitamin D supplements

The most reliable source of vitamin D are vitamin D3 supplements. When people supplement with the same dose of vitamin D3 there will be people who get higher vitamin D blood levels than others, as absorption in the gut is different for different people.  The ones who have relatively low vitamin D blood levels are often called “slow vitamin D absorbers”. But when the vitamin D3 dosage is increased even those people will reach the recommended high normal range (50-80 ng/mL).

Vitamin D blood level

The vitamin D blood test has the scientific name “25-hydroxy vitamin D level”. This is now the recognized gold standard for determining who is deficient or has normal levels with respect to vitamin D. The following 2013 publication has studied the vitamin D level of 1,470 healthy Swiss men and women, 60 years or older. Vitamin D levels were classified as severely deficient when the level was below 10 ng/mL. The vitamin D level was deficient between 10 and 20 ng/mL. The level was insufficient when between 21 and 29 ng/mL. A level above 30 ng/mL is normal.

8 % of the subjects were severely insufficient and 66% had insufficient vitamin D levels. Only 26.1% of the subjects had normal levels. Over 50% of healthy older Swiss (above the age of 70) had insufficient vitamin D levels.

Which vitamin D level is safe and which is not?

A peer-reviewed publication of the effects of vitamin D in health and disease contains 269 references.

What vitamin D level is optimal? This question was reviewed in this paper.

  • Below 15 ng/mL the immune system is paralyzed
  • With a level above 30 ng/mL the immune system is working
  • A level of 50-80 ng/mL has the immune system working optimally
  • Above 150 ng/mL toxic vitamin D levels start
  • With 300 ng/mL severe toxicity begins

Vitamin D toxicity

It is only with high levels of vitamin D (more than 150 ng/mL) that you have to worry about high calcium levels in the blood or kidney stones (toxic levels). But the key is to not exceed 80 ng/mL regarding the vitamin D blood level. This gives you a lot of flexibility before you reach toxic levels (above 150 ng/mL). For those who want more information, here is a thorough, peer reviewed publication about vitamin D toxicity with 59 references.

Vitamin D supplement compliance

The question is why not more people take adequate vitamin D3 supplements.  We know that vitamin D can prevent so many chronic diseases including serious viral infections. The answer is complex, but it includes a fear of the population of vitamin toxicity (kidney stone and high calcium levels). However, as pointed out before, this occurs only above a vitamin D level of 150 ng/mL. With proper vitamin D blood level monitoring you never reach toxic levels of vitamin D.

Denial

Denial likely is another major factor. People feel that if they have a balanced diet, they would be protected from vitamin D insufficiency. As pointed out before this is a grave error to think as our food does not contain sufficient vitamin D to strengthen our immune system.

False security with low doses of vitamin D

Finally, there are people who think that low doses of vitamin D, like 1000 IU of vitamin D daily, would be enough. But it is not enough. This is why testing vitamin D blood levels is so important. It is a reality check. The blood level must be in the high normal range (50-80 ng/mL). At this level the immune system functions optimally.

Compliance issues

In this context there was an interesting study done by LifeExtension, a company that publishes monthly health magazines. In this study the company examined the vitamin D blood levels of LifeExtension members. They are the ones who should be knowledgeable in how important it is to have good, preventative vitamin D blood levels. The study showed that 38% of the vitamin D test results were less than 30 ng/mL. In addition, 69% of the vitamin D tests were less than 40 ng/mL. Finally, 85% of the vitamin D test results were less than 50 ng/mL. What this means is that LifeExtension members were non-compliant when it came to taking regular adequate vitamin D3 doses. This resulted in levels that were too low for the majority to protect them from the Covid-19 coronavirus.

Covid-19 coronavirus infections and vitamin D blood level

There is a tight relationship between vitamin D blood levels and the strength of the immune system. Essentially, coronavirus mortality measures who is vitamin D deficient. Without enough vitamin D on board the virus penetrates into the blood stream and penetrates the lining of the respiratory tract. Next the cytokine storm develops, which leads to viral pneumonia. Higher doses of vitamin D3 will mitigate the course of Covid-19 coronavirus.

Adequate Vitamin D Level Strengthens the Immune System

Adequate Vitamin D Level Strengthens the Immune System

Conclusion

The Covid-19 coronavirus pandemic has taught us how important an intact immune system is to survive the virus when you get it. We do know for some time how closely related a good vitamin D level is with the functioning of the immune system. I have reviewed here what a desirable vitamin D level is and how we can achieve this with oral vitamin D3 supplements. The goal is to achieve a vitamin D level in the upper range of normal (50-80 ng/mL). With a level like this the virus cannot penetrate the mucous membranes of the respiratory tract and even if it did, it cannot produce a cytokine storm in the blood that would lead to the deadly viral pneumonia or to blood clots. When the virus invades the bloodstream, vitamin D releases powerful antiviral polypeptides that can kill viruses within 1 to 2 days.

Cutting Out Bad Lifestyle Habits Increases Life Expectancy

By | addiction, alcohol, breast cancer, Cancer, Cardiovascular disease, cholesterol, Diabetes, diet, exercise, Fitness, food, heart attack, Inflammation, lifestyle, lung cancer, Mortality, Nutrition, Obesity, Prevention, Stroke

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

Five bad lifestyles and life expectancy 

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

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

Diseases that kill prematurely

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

Additional life expectancy

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

For men:

When cancer free    When free of heart issues   Without diabetes

6 more years             9 more years                         10 more years

For women:

When cancer free    When free of heart issues   Without diabetes

8 more years            10 more years                       12 more years

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

Diseases caused by poor lifestyle habits

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

Cardiovascular disease

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

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

Cancer

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

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

Diabetes

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

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

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

Chronic diseases

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

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

Cutting Out Bad Lifestyle Habits Increases Life Expectancy

Cutting Out Bad Lifestyle Habits Increases Life Expectancy

Conclusion

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

Facing bad lifestyle habits

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