Adequate Vitamin D Level Strengthens the Immune System

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.

Here are some peer-reviewed publications on vitamin D:

Take Enough Vitamin D3

Many people supplement with 300 to 400 IU of vitamin D3, but do they take enough vitamin D3? There is a simple way of finding out: ask your doctor to order a 25-hydroxyvitamin D blood test.   This will show whether the gut absorbed enough of the essential vitamin. It will also show whether or not your vitamin D3 capsules or tablets were strong enough. It is now generally accepted that a good range of the vitamin D blood level is between 50 and 80 ng/ml. Unfortunately many Americans who come down with various diseases have blood levels of less than 30 ng/ml. Here are some facts about what a lack of vitamin D3 can cause.

Increased risk of mortality with lower vitamin D levels in ICU patients

  1. A New England Journal study from 2009 reported about 1100 patients in Intensive Care Units (ICU). Their average vitamin D blood level was only 16 ng/ml. They tracked the mortality rates depending on the vitamin D blood level. Insufficient vitamin D levels showed an association with a mortality rate of 45%. An intermediate level had a mortality rate of 35%. And a satisfactory level of vitamin D had a mortality of only16%. Between the low level of vitamin D and the normal level there was a 3-fold difference in mortality!
  2. Another study from 2015 repeated the mortality study with 135 ICU patients. Researchers correlated Vitamin D blood levels with mortality rates of patients. When vitamin D levels were below 12 ng/ml, there was a mortality rate of 32.2%. Patients with higher levels of vitamin D had a mortality rate of 13.2%. The authors concluded that vitamin D blood levels were an independent risk factor for mortality. Patients less than 12 ng/ml had a 2.4-fold higher risk of dying than patients with normal vitamin D levels.

Do patients with multiple sclerosis take enough vitamin D3?

Perhaps one of the earliest results of vitamin D3 research was the following observation. More than 90% of patients with multiple sclerosis were deficient in vitamin D blood levels. Their levels were below 20 ng/ml. Other researchers showed that vitamin D could directly tone down the aggressiveness of the immune cells of MS patients. These were the ones that attacked the myelin sheath. As a result of this knowledge it is important for MS patients to take high enough vitamin D3 supplements. When they reach good vitamin D blood levels their MS is better controlled.

Canada as a northern country has 291 MS patients per 100,000 people. Contrast this to 110-140 MS patients per 100,000 people in the northern US (between the 37th parallel and the US/Canadian border). In addition south of the 37th parallel there are only 57-78 cases of MS per 100,000 people. Researchers have concluded that the less sun light people get, the higher the rate of MS in the population will be. However, instead of sun exposure you can supplement with vitamin D3 capsules to get the blood vitamin D levels up to the range of between 50 and 80 ng/ml.

Do stroke patients take enough vitamin D3?

Strokes are very common. About 6.8 million Americans survive a stroke and live with various disabilities. 15% die shortly after their stroke. 40% are left with moderate to severe disabilities. Many require special care.

  1. Studies have shown that patients with the lowest level of vitamin D have the poorest functional outcomes. Moreover, for every 10 ng/ml decrease in vitamin D levels the odds of a healthy recovery 3 months after the stroke fell by about half. This was independent of age and the initial stroke severity.
  2. In another 2015 study from South Korea 818 stroke patients took tests to evaluate whether they had adequate vitamin D blood levels. There was a clear division between those whose levels were higher than 10 ng/ml or lower. When the vitamin D level was higher, there was a 90% better recovery from their stroke after 3 months. In comparison those whose vitamin D levels were below 10 ng/ml had poor recovery rates. Experts say that vitamin D levels should stay in the range between 50 and 80 ng/ml. This will prevent numerous diseases.

Do diabetics take enough vitamin D3?

  1. Vitamin D3 can silence diabetes genes in connection with the right diet and cofactors of zinc and magnesium. A Mediterranean diet can stabilize the metabolism and fight inflammation. Zinc and magnesium are important cofactors in enzymes necessary to prevent diabetes. Vitamin D3 and omega-3intake are helping to control inflammation and preserve beta cells in the pancreas in diabetes patients. This is important for continued production of insulin.
  2. A Chinese research team found that vitamin D3 protects beta cells in the pancreas from dying off. The finding was that vitamin D3 receptors in the insulin producing cells prevented the dying off of these cells, as long as there was enough vitamin D available. Insulin production by the pancreas remained effective. And insulin is vital for long-term survival of diabetes patients. The key for diabetes patients is to take adequate doses of vitamin D3 to protect their insulin producing beta cells.
  3. A 2015 Italian study showed that micro vascular complications in diabetes patients were high, if the vitamin D3 blood levels were low. If patients had high levels of vitamin D3, there were no complications such as retinopathy or nephropathy. But if levels were below 20 ng/ml, damages were significant in the capillaries of the eyes and kidneys.

Do patients with inflammatory conditions take enough vitamin D3?

What do the lining of the arteries, the inflamed joints, a degenerative meniscus and heart attacks and strokes have in common? It is the inflammation that changes the body chemistry. It gets even more complicated, because the extra calories that we consume get stored as visceral fat. This is done automatically when you eat too much sugar and starchy foods. When the glycogen stores are full, any surplus sugar gets metabolized by the liver into triglycerides, fatty acids and LDL cholesterol and gets stored as body fat. The most active fat is the visceral fat between our guts and around our body organs. This produces interleukins and other inflammatory cytokines that circulate in the blood causing inflammation in all our arteries. Interleukin-6 is an inflammatory cytokine. High interleukin-6 levels contribute to causation of various cancers.

This 2015 study from Seattle University followed 218 obese postmenopausal women with a body mass index of larger than 25.0 for 12 months. Both received weight loss intervention and either 2000 IU of vitamin D3 daily or a placebo pill. Both groups lost about 5 to 10% of weight in 12 months. However, the interleukin-6 level of the vitamin D3 group had a reduction of 37.3%. This was in stark contrast to the placebo group where the interleukin-6 level reduction was only 17.2%. This type of research shows the incredible power of vitamin D3. This likely is the reason why several cancer frequencies can show a reduction with regular vitamin D3 supplementation.

Attention deficit disorder and vitamin D3

  1. Other research compared a group of 37 children with attention deficit hyperactivity disorder (ADHD to 37 normal children. Blood levels of vitamin D were 19.11±10.10 ng/ml in the ADHD group and 28.67±13.76 ng/ml in the normal group. Other researchers have found similar findings, establishing that very low vitamin D levels have a connection with ADHD.
  2. A prospective study from Spain involving 1,650 mother-child pairs investigated the effect of mother’s vitamin D level during her pregnancy with the risk for ADHD by the time the child was 4 to 5 years old. Schoolteachers followed the standard test procedures to establish the ADHD diagnosis. The study showed that for every 10-ng/ml increment of the mother’s blood vitamin D level during her pregnancy the children had 11% less ADHD-like symptoms. The authors cautioned that it takes mega doses of vitamin D3 to reach these kinds of results. The usual 400 IU of vitamin D3 per day will not achieve the desired increase of vitamin D3 levels, but amounts of 5,000 IU to 8,000 IU are necessary to achieve this.

Schizophrenia and vitamin D3

A 2014 Meta analysis found that low vitamin D levels have an association with a 2.16-times higher probability of having schizophrenia than controls with normal vitamin D levels. Another study examined whether those patients who had an acute psychosis would have lower vitamin D blood levels than schizophrenia patients in remission or control patients without schizophrenia. Studies compared 40 patients with an acute psychosis to 41 patients in remission and 40 healthy controls. Patients with an acute psychosis had extremely low vitamin D blood levels, while patients in remission had much better vitamin D levels. Healthy controls had the best vitamin D levels.

Absorption and metabolism of vitamin D3

Magnesium plays a central role in activating vitamin D3. This publication points out that magnesium is also necessary for absorption of vitamin D3 in the gut. The activation of vitamin D3 is also partially responsible for vitamin D absorption. Both vitamin D3 and magnesium play an important role in bone and calcium metabolism. The fact that every body cell has vitamin D3 receptors shows how important it is for the maintenance of the body. Many researchers say that vitamin D3 qualifies as a hormone because of the specific effects on cells via vitamin D3 receptors.

Take Enough Vitamin D3

Take Enough Vitamin D3

Conclusion

Vitamin D3 is an important signaling hormone and vitamin that regulates the body’s calcium absorption and is responsible for bone metabolism. Research has shown that the lack of vitamin D3 causes several unrelated diseases, like rickets, multiple sclerosis, and schizophrenia. But other diseases, where a lack of vitamin D3 was present, were diabetes, attention deficit disorder and strokes. When patients with elevated inflammatory markers take vitamin D3 their interleukin-6 levels dropped by 37.3%. To achieve this, patients needed to consume at least 2000 IU. We all should have our vitamin D blood level measured from time to time. It should be between 50 and 80 ng/ml. Too many Americans are deficient in vitamin D3 and come down with the diseases mentioned! Prevention and supplementation go hand in hand. You can prevent a lot of diseases this way.

Vitamin D3 Protects Your Brain

More and more studies are showing that vitamin D3 protects your brain. It protects against MS, but also against Parkinson’s disease and Alzheimer’s disease. In the following I will review what evidence there is to support each of these topics.

Vitamin D3 protects your brain from multiple sclerosis (MS)

It has been known for some time that in the northern hemisphere MS is more common because of the lack of sunshine, which in turn produces less vitamin D3 in the skin.

MS is an autoimmune disease where immune cells attack the lining of nerves. Both nerve cells and immune cells have vitamin D receptors. It appears that immune cells are calmed down by vitamin D3 and remission of an MS relapse is more likely.

There are two forms of MS, the relapsing-remitting MS and the progressive MS. The first one (relapsing-remitting) is more common. After a bout of active MS, the illness calms down and the condition of the patient is stable for some time until the next relapse occurs.

With progressive MS there are two forms, primary progressive MS and secondary progressive MS. The primary form is a case of MS where symptoms steadily worsen, without any remission. The secondary form of progressive MS occurs at the end of fairly stable relapsing-remitting MS. Symptoms become more pronounced and the condition deteriorates steadily from there.

Progression and disability in MS patients with various vitamin D3 levels

Dr. Fitzgerald and colleagues published a study in JAMA Neurology in 2015.

They took 1482 men and women who were on interferon beta-1b treatment. This treatment utilizes the immunomodulator interferon beta-1b and reduces the number of relapses in patients with MS. The study took place between November 2003 and June 2005. Results were analyzed between June 2013 and December 2014. The researchers measured vitamin D levels (as 25-hydroxy vitamin D). The vitamin D levels were obtained at baseline, at 6 months and 12 months.

The number of brain lesions were measured by MRI scans. All of the patients also underwent a functional test, called expanded disability status scale. This measured impairment of ambulation, ability to communicate and activity levels.

Results of this study showed marked differences between patients with high and low vitamin D levels. Those patients who had the highest vitamin D blood levels (more than 40 ng/mL) had the lowest rates of new MS lesions. Previous studies had found that a low blood level of vitamin D (less than 25 ng/mL) in patients was associated with a much higher risk of developing MS. Dr. Fitzgerald’s study showed that a 50.0-nmol/L increase in serum vitamin D levels associated with a 31% lower rate of new MS lesions. Patients with the highest vitamin D level of more than 100 nmol/L had the lowest amount of new MRI lesions (47% less than the patients with the lowest vitamin D levels).

Another study showed that a low-dose vitamin D level accelerated MS. There was a 5.9-fold risk converting the initial relapsing-remitting form of MS into the secondary progressive form of MS.

All these studies show that vitamin D3 can decrease the risk of getting MS. In addition vitamin D3 also delays progression in those who have MS.

Vitamin D3 protects your brain from Parkinson’s disease

Vitamin D3 plays a role in preventing Parkinson’s disease.

Parkinson’s disease is a neurodegenerative disease that causes tremor in muscles, causes balancing problems and eventually can lead to dementia. A metaanalysis was done in 2014 and 7 studies where identified to be relevant. The authors were looking for correlation of vitamin D levels with Parkinson’s disease. The study included 1008 patients in the metaanalysis with 4,536 controls.

  • Patients with a vitamin D level of less than 75 nmol/L had a 1.5-fold higher risk of developing Parkinson’s disease than the controls.
  • Patients with a vitamin D level of less than 50 nmol/L were at a 2.2-fold higher risk of developing Parkinson’s disease.

Another metaanalysis utilized 5,690 Parkinson’s disease patients and 21251 matched controls.

It found that vitamin D levels of less than 20 ng/ml were associated with a risk of 2.08-fold to develop Parkinson’s disease. Interestingly, vitamin D3 supplementation reduced the risk of Parkinson’s disease by 38%. Outdoor work reduced the risk of developing Parkinson’s disease by 28%.

Vitamin D3 protects your brain from Alzheimer’s disease

Alzheimer’s disease is a neurodegenerative disease of old age. We know that it is much more common in patients with type 2 diabetes where insulin levels are high. Studies have shown that Alzheimer’s disease can be termed type 3 diabetes.

The resulting neurofibrillary tangles and amyloid-beta deposits damage nerve cells, which are responsible for the memory loss and the profound personality changes in these patients.

What does vitamin D3 have to do with this?

A 2014 study showed that a low vitamin D level was associated with a high risk of dementia and Alzheimer’s disease.

Specifically, the researchers found the following observations.

  • Vitamin D level of less than 10 ng/ml: 122% increased risk of Alzheimer’s
  • Vitamin D level 10 to 20 ng/ml: 51% increased risk of Alzheimer’s

The same research group found in two trials that vitamin D deficiency leads to visual memory decline, but not to verbal memory decline.

Vitamin D3 combined with metformin suppresses cancer

The newest development with respect to vitamin D3 is the finding that it also has anti-cancer effects. Dr. Li demonstrated that vitamin D reduced prostate cancer cell line growth by 45% while metformin alone reduced it by 28%.

But when both vitamin D and metformin were present in the cell cultures there was growth inhibition of 86%. Dr. Li explained that vitamin D potentiated the growth inhibitory effect of metformin.

Vitamin D3 protects your brain: guidelines to proper vitamin D3 dosing

For years the medical profession stated that 400 IU of vitamin D3 would be enough supplementation. It may be enough to prevent rickets in children. But these low doses will be insufficient in many patients who are deficient for vitamin D to prevent MS, Parkinson’s disease, Alzheimer’s disease or cancer.

A study on medical staff in Northern India showed that 85% of the staff had very low vitamin D levels of less than 10 ng/ml.

It took high doses of vitamin D3 to increase the vitamin D level in the blood.

Generally supplements of vitamin D3 of 5000 IU to 8000 IU are the norm now. But some patients are poor absorbers and they may require 15,000 IU per day. The doctor can determine the patient’s requirement for vitamin D by doing repeat vitamin D blood levels (as 25-hydroxy vitamin D). The goal is to reach a level of 50-80 ng/ml. The optimal level with regard to nmol/L is 80 to 200 (according to Rocky Mountain Analytical, Calgary, AB, Canada).

Vitamin D3 Protects Your Brain

Vitamin D3 Protects Your Brain

Conclusion

Many people are deficient with regard to vitamin D, and they do not know it. The most important thing is to do a vitamin D blood test to assess your vitamin D status.

We know for a long time that vitamin D plays a role in bone metabolism and this is why women approaching menopause often need vitamin D3 supplementation. But it may come to you as news that vitamin D3 also protects from MS, Parkinson’s disease and Alzheimer’s disease. In addition, as indicated above, we know that vitamin D3 when taken regularly suppresses many cancers.

When you realize that all body cells have vitamin D receptors on their surface, it is no surprise that vitamin D3 is so important to take. The vitamin D3 receptors must be there for a reason. When you deprive your body of this valuable vitamin, the high risk of degenerative diseases will be the consequence.

High Vitamin D3 Prevents Cancer

In the last few years we learnt a lot about vitamin D3, but the newest thing is that high vitamin D3 prevents cancer.

Researchers at the University of California, San Diego School of Medicine reported that with respect to several cancer types higher doses of vitamin D3 led to less cancer over a period of time.

The cancers investigated were colon cancer, breast cancer, and lung and bladder cancer. People absorb vitamin D3 differently.  The researchers found that the best way to measure vitamin D3 concentration in the body is to use serum 25-hydroxyvitamin D (25(OH)D). In the past people did not pay much attention to this matter. However, several studies including the present study showed that in patients who had a lower level of 20 ng/ml cancer rates were higher.

Comparison of two cohort studies

The researchers used data from two prior studies, a randomized clinical trial of 1,169 women and a prospective cohort study of 1,135 women. The researchers found that the age-adjusted cancer incidence was 1,020 cases per 100,000 person-years in the randomized clinical trial, called “Lappe cohort”. The other prospective cohort study was called the “GrassrootsHealth cohort” where cancer incidence was 722 per 100,000 person-years. The interesting fact was that the Lappe cohort median blood serum level of 25(OH)D was 30 nanograms per milliliter, while the GrassrootsHealth cohort had a higher level of 25(OH)D of 48 ng/ml.

Higher vitamin D levels correlate with lower cancer incidence

This likely explains the lower cancer rate in the GrassrootsHealth cohort. Researchers combined the two trials in order to increase the statistical significance . The striking finding was that above 40 ng/ml the overall cancer risk was more than 71% lower than for the group of people whose level of 25(OH)D was 20 ng/ml or lower. The above ScienceDaily article was based on this scientific study.

Other studies showing high vitamin D3 prevents cancer

AfroAmerican men had less prostate cancer, if vitamin D level was higher

In a 2015 study Afro American men were found to have 71% less prostate cancer, if their serum 25-hydroxyvitamin D level was at least 30 ng/ml or higher.

Prospective study showing high vitamin D levels cancer protective

This 2006 study reported a 14-year prospective follow-up in men where all cancers were counted and blood serum 25-hydroxyvitamin D levels were correlated to cancer incidence. An increase of 25 nmol/L (=10 ng/ml) in predicted serum 25(OH)D level showed an association of a 17% reduction in total cancer incidence, with a 29% reduction in total cancer mortality and a 45% reduction in digestive-system cancer mortality. These investigators stated that it takes about 1500 IU of vitamin D3 increase per day to achieve an increment of serum 25(OH)D increment of 25 nmol/L (=10 ng/ml).

University of Arizona Cancer Center study

A publication from the University of Arizona Cancer Center in Jan. 2016 is more critical of the evidence regarding vitamin D3 and the claim that it lowers cancer rates. The researchers reviewed the cancer literature and found that for colorectal cancer there is a clear inverse relationship between serum 25(OH)D levels on the one hand and rates and mortality of colorectal cancer on the other hand. However, with breast cancer the literature was more divided. Only higher vitamin D levels were related to a lower risk for progression of breast cancer and a lower mortality rate. Randomized, double-blind clinical trials with regard to breast cancer failed to show effectiveness on cancer prevention or reduction of mortality. For prostate cancer conditions were similar with the exception of a study using 4000 IU of vitamin D3 per day, which inhibited progression of prostate cancer.

Mouse model regarding ovarian cancer and vitamin D

In a mouse model using a carcinogen to induce ovarian cancer there was an inverse dose-relationship between vitamin D3 and ovarian tumor development both in tissue culture and in the animal.

How high vitamin D3 prevents cancer

Immune stimulating effect of vitamin D3

Several studies have attempted to speculate how vitamin D3 may prevent cancer. Chirumbolo summarized the literature and noted that vitamin D3 has been shown to function as an immune cytokine stimulating the immune system non-specifically.  Vitamin D3 is also anti-inflammatory and counters insulin resistance and inflammatory kinins in obesity. Flavonoids with their antioxidant activity are also cancer preventing. We know that low levels of vitamin D have an association with higher cancer frequency. This means,. it is important to use vitamin D3 as supplements in our diet.

Chinese study describing action of vitamin D3 in detail

This Chinese study examined the effects of vitamin D3 on cancer prevention. It found that vitamin D3 combines three specific actions in one. Vitamin D3 is anti-proliferative meaning that it stops uncontrolled cell division. Secondly, it has an apoptotic (cell death) effect, which means it supports the removal of cells that are dying. If they are dying, but not removed, cancer can occur from these cell remnants. The third effect of vitamin D3 is that it has differentiating effects in several malignant cell types. When cancer cells are non-differentiated (=more immature cells) cancer can multiply quickly. Mature cells find it more difficult to turn cancerous. This is an effect that controls the speed by which cancer cells divide and how quickly cancer metastasizes.

There still is some confusion about the effects of vitamin D3 regarding cancer prevention. In colorectal cancer the statistics are clear: vitamin D3 can significantly prevent colorectal cancer to a large extent. There are also preventative effects in breast cancer and prostate cancer. But individuals may have to take at least 4000 IU of vitamin D3 or more. This is particularly true in higher latitudes where sunlight exposure is lower in the wintertime. Also, people absorb vitamin D3 differently. For this reason it is important to at least check your serum 25-hydroxyvitamin D levels on a few occasions. This will tell you whether your vitamin D3 supplementation is sufficient. Aim for levels in the 50-80 ng/ml, which is health promoting.

Apart from cancer prevention vitamin D3 is also important for prevention of cardiovascular disease. This is particularly true for diabetes, osteoporosis and Alzheimer’s disease.

Sun Exposure Helps Many Symptoms

For the past few years it has become evident that sun exposure helps many symptoms. Patients with psoriasis have skin plaques on their skin. With sun exposure some of them disappear and the skin appearance improves. Patients with seasonal affective disorder have worsening of their depression over winter. Depression lifts with more sun exposure in the spring. Even a complicated disease like MS, which is more common in the northern latitudes, improves with sun exposure or a move to the southern states.

Osteoporosis: sun exposure has a positive effect

Osteoporosis was the subject of an April 2016 study from Argentina.

The researchers counted the amount of actinic keratosis lesions on the skin of subjects. This correlated well with lifetime sun exposure. Next they measured the  occurrence of hip fractures from osteoporosis. There was a correlation of the two. This case control study had 51 patients with hip fractures. Controls were 59 patients from the same hospital without hip fractures. The mean age was 80 years of age. 23.5% of patients with a history of hip fractures were observed to have actinic keratoses. In contrast 40.7 % of actinic keratoses were found in controls.

Sun exposure prevents hip fractures

The authors conclude that higher sun exposure is protective of hip fractures, but led to more actinic keratoses. They also stated that higher actinic keratoses rates, which are precancerous skin lesions are a risk for developing skin cancer. It is important to balance risk of osteoporosis from a lack of sun exposure with the risk of skin cancer from overexposure to the sun.

We know that higher doses of vitamin D3 in combination with vitamin K2 and calcium supplementation prevent osteoporosis. Reasonable daily doses are 5,000 to 10,000 IU of vitamin D3 per day, 200 micrograms of vitamin K2 per day and 500mg of calcium daily.

Psoriasis: sun exposure helps many symptoms

Psoriasis is an inflammatory condition of the skin with plaques and a characteristic skin rash. This February 2016 study from Turkey showed significant differences between women with psoriasis versus controls. Bone density studies showed lower levels in psoriatic females than in female controls. Female psoriasis patients had lower vitamin D levels than female controls. Male psoriatic patients showed no difference from controls. Low levels of vitamin D3 may be triggers for osteoporosis to develop in female psoriasis patients. Inflammation may also be a contributory factor. There was an elevation of the C-reactive protein (CRP) in female psoriasis patients.

Clinical observations have shown for years that the rash of psoriasis patients tends to improve during the summer.

Seasonal affective disorder: sun exposure lifts the mood

Seasonal affective disorder (SAD) has been known to respond to light therapy. Typically it peaks in the winter months and presents in mostly females who live far away from the equator. They improve when they travel to a sunny spot such as the subtropics or the southern states of North America during the winter months. But light therapy, vitamin D3, antidepressant therapy and counseling the mood swings of seasonal affective disorder will lessen.

In this 2014 study it was shown that depression in older people was not related to the darker months (between October and March). The summer depression rates in older people were identical to the winter depression rates.

Clinical trials with seasonal affective disorder (SAD) patients

In a group of 38 patients with SAD 14 patients were treated with white light visors, 15 with infrared visors and 9 served as a control (visors, no light). Both white light and infrared treated groups showed prevention of SAD while the control group developed SAD.

A 6-week trial was published March 2015. It involved 78 patients (51 Afro-Americans and 27 Caucasians). They all had SAD and received a treatment with 10,000-lux bright light for 60 min daily in the morning. Caucasians had a response rate of 75%. African-Americans had a response rate of only 46.3%. The investigators found that the symptomatic improvement and the rate of treatment response were the same in both groups. The researchers found that the Afro-American subgroup of patients required more education resources. This can overcome the inconsistent application with the bright light.

Vitamin D trials regarding SAD patients

In a study involving 185 female undergraduates of the Pacific Northwest, vitamin D blood levels were measured and a correlation of low vitamin D with depressive symptoms was found in SAD patients.

In a small study the hypothesis was tested that vitamin D3 in higher doses would be beneficial for SAD patients. Eight subjects received a treatment with 100,000 I.U. of vitamin D3, while seven subjects received phototherapy. All subjects had their vitamin D blood levels checked. Interestingly the vitamin D3 group improved on all depression scales. The phototherapy did not show improvement on the depression scale. The vitamin D level increased 74% in the vitamin D3 group and 36% in the phototherapy group.

Light exposure and vitamin D supplementation for SAD

All of these studies seem to indicate that SAD is more common in a younger population while in older people depression seems to be year-round. SAD does respond very well to 1-hour exposure of 10,000 lux of light in the morning. On a sunny day a walk in the sun for 1 hour is equivalent to an exposure at home with a SAD light. High dose vitamin D3 supplementation makes sense as low vitamin D levels were a persistent finding among SAD depression patients.

Multiple sclerosis: sun exposure makes a difference

Multiple sclerosis (MS) is more common in northern latitudes of the northern hemisphere. It is thought that sun exposure leads to higher vitamin D3 production in the skin, which prevents MS. On the other hand, once the diagnosis of MS is certain sun exposure or high doses of vitamin D3 can make it better.

This 2015 Australian study showed the same findings with a large group of MS patients.

This 2015 study from Sweden indicates that there is a compelling connection of prevention of MS through sun exposure or the taking of supplements of vitamin D3. In view of this evidence the authors suggest that you should take vitamin D3 supplements for prevention of MS before trials confirm this further.

Sun protection needed to prevent skin cancer

We have been hearing the slogan “slip, slop and slap” for skin cancer prevention. Slip, slop and slap stands for: slip on a shirt; slop on the sunscreen and slap on a hat. This publication dated March 2016 questions whether the precautions have been too zealous.

On the other hand the statistics regarding higher precancerous actinic keratoses in patients without osteoporosis are alarming too. It seems better to use high doses of vitamin D3, which will prevent osteoporosis, depression (SAD), MS and also improve psoriasis. Sun protection has decreased skin cancer, but did not curtail melanoma rates because sunscreen lotion can be penetrated by infrared radiation.

Use common sense for skin cancer prevention

This means that you should listen to the advice to stay out of the intense sun between 11AM and 3PM. Use vitamin D3 supplements in higher doses as this protects your skin. Research from England indicates that melanoma patients are usually the ones that are susceptible to melanoma genetically. They also have low vitamin D levels in the blood to a certain degree from skin cancer formation. The researchers recommend strongly that those at risk for melanoma need to be on higher vitamin D3 supplementations. A patient with a diagnosis of melanoma should receive high doses of vitamin D3.

Sun Exposure Helps Many Symptoms

Sun Exposure Helps Many Symptoms

Conclusion

It is not a myth: sun exposure helps many symptoms as explained above. Diverse body systems like osteoporotic bones, psoriatic skin and seasonal affective disorder respond to sun exposure. Sun exposure also prevents MS, a degenerative central nervous system disorder. The effects of vitamin D3 can explain some of this effect. It likely stems from sun exposure to the skin. But sunlight has hormonal effects. This occurs through the optic pathways and connections to the hypothalamus. We know that the sun helps combat many symptoms, but more research will be necessary, till we know exactly how it works.

Depression Needs Treatment

Depression is common and depression needs treatment. 10% of all men and 20% of all women have a period of depression in their lives. In people with medical illnesses depression is more common: 20% to 40% (Ref.1).

First, the peak age for depression is usually the age of 25 to 44. There are special groups where depression is also common. In adolescents 5% are affected with depression and 13% of women tend to get depressed after delivery, a condition called postpartum depression.

Second, in any age group with depression there is a risk of suicide, but with adolescents this is particularly true.

Third, about 10% to 15% of people with general medical illness are developing depression, such as patients with Parkinson’s disease, stroke, Alzheimer’s disease, cardiac disease, HIV infection, end-stage renal failure and cancer.

Causes of depression

Officially it is not known what causes depression. That is what medical textbooks say. However, other books like Datis Kharrazian’s book “Why isn’t my brain working?” offers several scenarios that can cause depression and he has examples of cases that were cured of depression (Ref.2). He points out that deficiencies in two major brain transmitters can cause depression: serotonin and dopamine.

Serotonin

First of all, serotonin is produced in the midbrain from the amino acid tryptophan in two biochemical steps. It is important to realize that these biochemical conversions require iron, vitamin B6, vitamin B12, niacin, folic acid and magnesium as cofactors. But you also need the “large neutral amino acid transporter” (LNAA) to transport tryptophan through the blood/brain barrier into the brain.

Dopamine

Furthermore, dopamine is a neurotransmitter that is produced in the frontal lobes of the brain. Notably, it is also necessary for learning. The brain synthesizes dopamine from tyrosine, which has to be manufactured in the liver from the amino acid phenylalanine. You need to have a healthy liver to produce tyrosine, which needs to be transported through the blood/brain barrier into the brain; similar to tryptophan this requires the “large neutral amino acid transporter” (LNAA). People with hepatitis, fatty liver, insulin resistance or diabetes may have problems with the LNAA transporter, which can cause dopamine deficiency (Ref.2). But they may also have low serotonin, if tryptophan did not enter the brain because of a transportation problem. This will happen with sugar overconsumption, as insulin resistance develops and affects the LNAA transporter resulting in both low serotonin and dopamine (Ref.2).

Inflammation

Finally, in the 1990’s researchers confirmed that inflammation is also a possible factor in the causation of neurological disease including depression. Ref. 2 points out that gut issues can become brain issues as inflammatory substances can leak trough a leaky gut into the blood stream and trough a leaky blood/brain barrier into the brain. Hypothyroidism can activate brain inflammation and lead to an imbalance of the neurotransmitters. Gluten sensitivity is also an important cause of depression through the inflammatory connection, but few physicians recognize the full impact of this.

Tests for depression

There are no laboratory tests that would define depression. However, every patient should receive a blood test to check for hypothyroidism, a common cause of depression. When the tests confirm hypothyroidism, the physician can easily treat this with thyroid hormone replacement.

Otherwise the physician diagnoses depression by doing a mental status examination, history and review of symptoms. A good start is to ask: “In the past 2 weeks how little interest or pleasure in doing things have you had?” and “Have you been feeling down, depressed, or hopeless in the past 2 weeks?” (Ref.3).

There are detailed psychometric questionnaires available such as the Beck Depression Inventory that can assist the physician to establish the diagnosis.

Myths of depression

One of the myths regarding depression is that it would be contagious. As a matter fo fact, a study on 2000 high school students showed that depression was not infective. The contrary was true: human interaction with friends who had a “healthy mood” improved depression. By the same token, when you constantly compare yourself with your Facebook friends, and you are not in the best mood, your mood may worsen and you could become depressed.

Treatment of depression

Despite advances in the treatment of depression the response rate with antidepressant therapy has a limit of 60% to 70%. According to Ref.4 inadequate dosing and misdiagnoses account for the fact that 30% to 40% of treated people with depression have treatment failures. Typically the first antidepressant involves a selective serotonin reuptake inhibitor (SSRI), but newer trials have shown that the older monoamine oxidase inhibitors (MAOIs) have a higher success rate when treating depression initially (Ref.4).

For example, a good antidepressant for mild to moderate depression is St. John’s wort, which is recommended by Ref. 5 as having less side-effects as other antidepressants.

In treating resistant depression the psychiatrist often employs other combinations of antidepressants. In addition the health professional recommends to add cognitive/behavioral therapy, which makes the overall treatment more successful. It goes without saying that complicated cases of depression belong into the hands of an experienced psychiatrist.

Suicides

Unfortunately a mental disease like depression still has a stigma attached to it. As a result many people are in deep denial about the fact that mental disease exists. Friends who do not understand depression may inadvertently say things that make the symptoms of the depressed person more severe and distance themselves at a time when they would need support from friends. The end result is that the patient feels lonely, misunderstood and that suicidal thoughts enter the mind. Men often resist seeking treatment for depression, women are better in seeking professional help and getting effective treatment.

Need for a psychiatrist to help prevent suicides

This is where a psychiatrist needs to intervene. If this does not happen, people start attempting suicide and finally commit suicide. In the US committed suicides have a gender ratio of male to female of 3:1 to 10:1. These situations become very difficult. The family needs to step in and talk to the patient. It is best to accompany the patient to the hospital for an assessment. You may want to go to the hospital in your private car or by ambulance. Don’t be shy to call 911 for an ambulance. Better to be cautious than have a major crisis that ends in completed suicide.

Alternative depression treatments

There are alternative treatments for depression.

  1. Magnetic therapy for depression: This therapy is also called transcranial magnetic stimulation (TMS) and was approved for Canada and in 2008 by the FDA. But it is not as powerful according to Ref. 3 as unitemporal electroconvulsive therapy.
  1. Bifrontal electroconvulsive therapy (ECT): Electroconvulsive therapy with two pedals applied to the front of the skull appears to have the best results in terms of treating depression.
  2. Omega-3 fatty acids (EPA and DHA) are powerful anti-inflammatory agents, which will take care of the inflammatory component of depression. Both fish oil and krill oil in combination give the optimal response as outlined here.

Vitamin D3 and light box therapy

  1. Vitamin D3 is also anti-inflammatory and will contribute to an improvement with existing depression, but it also helps prevent the development of depression when taken in regularly as a supplement.
  2. Light box therapy: The observation of seasonal affective disorder (SADS) can develop as a result of lack of light. This has led to the discovery that light boxes are helpful for treating depression and also for prevention of depression due to seasonal affective disorder.

The patients should use a light box for 30 minutes every morning during the fall and winter months. The box should emit at least 10,000 lux. Improvement can occur within 2 to 4 days of starting light therapy, but often it takes up to 4 weeks to reach its full benefit.

Avoid alcohol and too much sugar

  1. It is known for a long time that alcohol is a depressant; it can actually cause depression and in persons with bipolar disease it can trigger a flare-up of that disorder as well.
  2. Finally it matters what you eat: sugar and too much starchy foods (high glycemic index carbs) lead to insulin overproduction and insulin resistance. This causes inflammation, and this will cause depression. As mentioned earlier it also lowers the two key brain transmitters, dopamine and serotonin.

The solution is an anti-inflammatory diet, the Mediterranean diet without sugar and high glycemic index carbs; only low glycemic index carbs are part of this diet. This will normalize insulin production and eliminates inflammation.

B vitamins, electroacupuncture and exercise

  1. Vitamin supplements: Folate and vitamin B12: Up to 1/3 of depressed people have folate deficiency. Supplementation with 400 mcg to 1 mg of folic acid often helps. Vitamin B12 should also be taken to not mask a B12 deficiency (Ref.5). Folate and vitamin B12 are methyl donors for several brain neuropeptides.
  2. The symptoms of depression often improve with electro acupuncture, as shown in many studies. This treatment ameliorates the symptoms of depression and seems to work through the release of neurotransmitters in the brain (Ref.6).
  3. Exercise on a regular basis helps to equalize the mood and seems to exert a slight anti-depressant effect on the person who engages in regular physical activity.
Depression Needs Treatment

Depression Needs Treatment

Conclusion

I have attempted to show the complexity of depression and what we know about its causes and treatment. Very likely there are several causes for depression and further research will hopefully bring more clarity to this. Over the years psychiatrists have developed treatment modalities, both conventional and unconventional, by trial and error. The physician and patient need to use common sense: if a treatment is working, stick to it and use it. If it does not work, move on and try something else. More complex cases should be referred to a psychiatrist who has the most experience with patients that are difficult to treat. Do not neglect life-style factors and alternative depression treatments as they can often help to stabilize depression significantly. We all must be vigilant about suicide risks in depressed patients and act by calling 911, if necessary to intervene.

Forty Percent Of Premature Deaths Can Be Prevented

A new report from the CDC (Center of Disease Control) in the US has revealed that up to 40% of premature deaths could be prevented by simple lifestyle changes. As this link shows every year about 900,000 premature deaths occur in the US, which are due to 5 major diseases that in the opinion of the CDC can be prevented by 20 to 40%. Here are the diseases that kill: cancer, heart disease, COPD/emphysema, stroke and accidents/injuries. These conditions were responsible for 63% of all deaths in the US in 2010.

Let’s discuss each of these conditions and how one could lower the risk of dying from them.

1. Cancer:

The Framingham Heart Study has shown that smoking and cancer are closely related. Smokers who quit can significantly reduce their risk of getting cancer. We also know that exercise and prophylactic supplements like fish oil and vitamin D3 have cancer preventative effects.

Antioxidant supplementation that included beta-carotene, vitamin A, vitamin C, and vitamin E daily or on alternate days for 1 to 12 years, along with selenium supplementation reduced the incidence of cancer of the esophagus, colon, pancreas, stomach or the liver. Insulin resistance due to sugar and starch overconsumption is causing cancer, particularly breast cancer, colorectal cancer and endometrial cancer. I have discussed this in a recent blog.

Pollution has been linked to increased lung cancer risks as discussed here.

2. Heart disease:

Heart disease can be caused by several factors in combination. Lifestyle issues are important: Smokers need to quit smoking as the Framingham Heart Study has shown more than fifty years ago that smoking causes heart attacks. Obesity and diabetes also contribute significantly to the risk of heart disease. Often these are connected to faulty nutrition, which is another lifestyle issue that comes to mind when too much sugar and starchy foods are taken in; your liver will convert these into fatty acids, triglycerides and elevated, oxidized LDL cholesterol, which gets deposited under the lining of the arteries. A lack of exercise adds to this problem as a lack of exercise lowers the protective HDL cholesterol and fat is deposited under the lining of the arteries. Start exercising and your protective HDL cholesterol will rise, your total cholesterol to HDL ratio will lower to healthier levels and your risk for hardening of the arteries and for getting a heart attack will fall. If you have diabetes, it is important that you manage your blood sugars well; this means that if you inject insulin, you want the blood sugar tests to be within the normal range and the hemoglobin A1C values to be below 5.5%. Poorly controlled diabetes is an important cause of heart attacks and strokes. High blood pressure is also an important cause of developing heart attacks and strokes. It is important to control your blood pressure by taking blood pressure lowering pills and also by exercising regularly. Exercise seems to send a signal to relax the blood vessels thus lowering the blood pressure, which in turn prevents heart attacks.

3. COPD/emphysema:

Chronic obstructive pulmonary disease (COPD) or emphysema is mostly caused by chronic exposure to cigarette smoke from smoking. The earlier you can quit, the better your chances that your breathing will not be the limiting factor when you age. But it is also important to avoid exposure to other noxious gases, such as from welding and from exposure to pollution. This may involve a decision to move to a less polluted area. Or it might involve a job retraining. Those who are suffering from COPD can be helped to a certain extent by a portable oxygen tank with nasal prongs.

4. Stroke:

As mentioned before, quitting smoking, controlling high blood pressure and controlling blood sugar, if you suffer from diabetes have been shown to stabilize your blood vessels including the ones that supply your brain. The key is to prevent hardening of the arteries by a healthy lifestyle. Exercising and keeping your weight under a body mass index of 25.0 have been shown to be effective stroke prevention. Healthy nutrition as indicated above under “heart disease” is equally important for stroke prevention. Go green (eat more vegetables, consume more green smoothies), cut down grains, sugar and starchy foods and you will live longer without strokes and heart attacks. Remember, what’s good for your heart is good for your brain!

5. Unintentional accidents/injuries:

Wearing helmets when bicycling, wearing seat belts when driving in a car, avoiding risky behaviors are all measures that save lives. One factor stands out in all of this: if you drink too much, you run the risk of being involved in unintentional accidents or injuries. People may not like to hear this, but your brain lacks the natural inhibitory impulses when you are under the influence of alcohol, so you become more daring and you may not pay attention for the split second that could have prevented an injury or accident. People react very differently to alcohol. Some people feel inebriated after only ½ a glass of wine or beer whereas others can drink more before they make mistakes. The best is to be sober when you drive, ski, use power tools or walk in traffic. Even climbing ladders requires a clear mind!

Conclusion:

As the CDC said 20 to 40% of premature deaths (deaths that occurred before the age of 80) could have been prevented, if the above-mentioned recommendations were followed. Let me rephrase this: 180,000 to 360,000 premature deaths every year in the US before the age of 80 could have been prevented! Curative medicine cannot help with these statistics as a heart attack or stroke has happened when it has struck you. Cancer and end stage lung disease are similar conditions that you are suddenly faced with when they occur and unintentional accidents just seem to happen. This is where the importance of prevention can be seen, because these little baby steps every day are adding up to something formidable, a force to be reckoned with. Be part of the solution, think prevention!

Protecting Yourself From Environmental Toxins

Environmental toxins are toxins that may be in your drinking water, in what you eat, in the air you breathe, or they enter your body through your skin when you swim in contaminated water or walk on a sandy, wet beach.

In the following blog I will address some of these issues and how we can defend ourselves against toxins.

The youngest and most vulnerable

Toxins are particularly bad for infants and premature babies.

The reasons for this are the following ones: their kidney function (tubular secretion) is only 20% to 30% of that of an adult; the cytochrome P-450 enzyme system in the liver, one of the toxin eliminators is slowed down to only 25% to 50% of the adult activity and glucuronidation in the liver, another detoxification process, reaches adult levels only at the age of 3 years. The kidneys and the liver are limiting the removal of toxins by way of urine and bile in the newborn. Stomach acidity in a premature has a pH of 4.7, in a full-term newborn 2.3–3.6 and in an adult 1.4–2.0. This is important to note as a lack of stomach acid increases susceptibility of newborns and infants to gastrointestinal infections and cause diarrhea. Percutaneous absorption in newborns is much higher than in adults, which makes them very susceptible to absorbing toxins through the skin (Ref.1).

Diabetes from environmental toxins

Environmental toxins can cause insulin resistance and type 2 diabetes.

Bisphenol A (BPA) is used to make polycarbonate and epoxy resins and is found primarily in food and beverage containers. The world population has been exposed to this since 1957 and as a result 90% of US residents have detectable levels of BPA in their urine. Ref.2 explains that the higher the urine concentration of BPA, the higher the risk is for developing diabetes.

Persistent organic pollutants are another source of concern: pesticides and herbicides, dioxins, polychlorinated biphenyls, hexachlorobenzene, and hexachlorocyclohexane have all been found in humans. Several investigators have shown that virtually all of the risk in obese patients to develop diabetes comes from the fat-soluble persistent organic pollutants (Ref.2).

Inorganic arsenic is another pollutant that is found in soil and rock naturally and finds its way into the drinking water. About 8% of the public water system of the US exceeds 10 mcg/L for drinking water, which has been set as the safe limit for drinking water by the US Environmental Protection Agency’s standard. Anything above those levels is considered toxic.Ref.2 describes that people who ingest inorganic arsenic will excrete it in the urine; the highest group with arsenic in their urine had a risk of 3.58-fold to develop diabetes when compared to the lowest group. Curiously enough organic arsenic that is found in fish and shellfish is excreted in the urine unchanged and does not cause diabetes. Overall this indicates to me that nobody should consume or cook with contaminated water that contains inorganic arsenic. Reverse osmosis filters will protect you from this risk.

Protecting Yourself From Environmental Toxins

Other toxins around the house

Volatile organic compounds are often contained in carpets, but also in laser and inkjet printers. They are part of everyone’s life as this link shows. Varied symptoms like irritation of eyes, nose or throat, breathing problems, headaches, loss of coordination, damage to the liver, kidneys and the brain have been reported after exposure to volatile organic compounds. Long-term exposure can even cause cancer in animals and has been suspected to cause cancer in humans as well.

Air fresheners and cleaning solutions that contain ethylene-based glycol ethers and terpenes have been the subject of a study that examined concentrations in the air and interaction with ozone that can also be released by some cleaners. As this link shows the investigators concluded that with exposure to high enough concentrations and long enough exposures to these fumes lung cancer can be caused in cleaning personnel. They recommended to use cleaning solutions only in diluted form and to air out the premises well after cleaning. Another component of many air fresheners and cleaning chemicals is paradichlorobenzene, the same chemical that is contained in mothballs.

There have been problems with flame retardants: polybrominated diphenyl ethers, which are cancer producing; they have been outlawed in the US since 2004, but older mattresses, upholstery, television, computer casings and circuit boards may still contain them.

Lead and mercury poisoning, and radioactive pollutants

Manufacturers were not allowed to use lead in paints anymore since 1978. Paint from buildings older than that still may contain lead. There have been serious lead poisonings in children who were gnawing on items painted with lead containing paint. Lead causes problems with your central nervous system, brain, blood cells and kidneys. Just last year a news story about lead found in fashion jewelry surfaced warning about cheap fashion jewelry from China. Lead form these items can be absorbed through the skin and cause lead poisoning. Because of the apparent lack of regulations in China it is my recommendation not to buy anything that goes into your mouth or on your skin, if it has been grown or produced in China.

Mercury from tuna and other predator fish: It is sad that the oceans are polluted to the point where it has become unsafe to eat predator fish as there is an accumulation of mercury through the food chain.

How did things develop this way? Back 100 years and more ago gold panning and the purification process of gold caused mercury to enter into rivers and allow mercury to end up in the oceans where it has since accumulated; it just sits there as it has nowhere to go.

Coal burning (yes, there is mercury in coal) has also contributed to this by smoke being emitted from smoke stacks containing mercury vapors, which ended up returning to earth as polluted rain and drained through the river system into the oceans.

It is monomethylmercury that accumulates in the tissue of humans. It affects many organs, such as the brain, kidneys, lungs, and skin. It causes various symptoms like red cheeks, fingers, and toes; there can be bleeding from the mouth and ears; it can cause rapid heartbeats, high blood pressure, intense sweating, loss of hair, teeth, and nails. It also can cause blindness, loss of hearing, impaired memory, and lack of coordination, disturbed speech and birth defects. You may think all mercury comes from the outside. However, silver amalgam fillings in your teeth could also be the source of mercury poisoning. It is a good idea to replace amalgam/mercury fillings with ceramic fillings.

There are many forms of other marine pollution as this link shows.

One particular concerning aspect is pollution with radioactive materials as the Fukushima disaster in Japan has shown. Following the catastrophe on March 11, 2011 there have been several leaks of radioactive material into the ocean, which are described here. Dr. John Apsley II pointed out that with the explosions in Fukushima there were also several releases of radioactive pollution into the stratosphere. This pollution has subsequently traveled around the globe and has come down as radioactive rain. He has made it his ambition to help people minimize radiation exposure from nuclear accidents such as Fukushima.

Protecting yourself from toxins

Having said that pollution and toxins are problems that we are living with, how can we protect ourselves from all of that?

1. Avoid as many unsafe chemicals around you as you can. This includes checking ingredients in hair care and body care products, toothpaste, hair dyes, cosmetics, mouthwashes and underarm deodorants.  I have written a blog about toxins in the bathroom and what you should watch for.

2. I would recommend you switch from a standard food to organic food. It has become unsafe to eat non-organic meats, leafy vegetables, vegetables and fruit. There are too many residues of herbicides and pesticides contained also in meat, not only in vegetables and fruit. Washing will not remove these substances, even though some merchants may tell you otherwise. Buyer beware!

3. Detoxification methods are available and I have reviewed them in this blog. Briefly, to remove lead and mercury a formal intravenous chelation protocol should be followed.  Depending on how many heavy metal toxins you have on board, you may need only a few treatments or else up to 20. Here is a more conservative website stating that it would be safe to have silver amalgam fillings. I think that gold and ceramic fillings are much safer.

4. Genetically modified food is another danger as I have summarized in this blog. This is another reason why I like to stick to organic food. There is evidence that GMO food causes autoimmune diseases, infertility and chronic inflammation that can eventually lead to cancer. It may take decades to prove this, but I am not willing to be a human guinea pig.

5. I have mentioned in a prior blog that we live in a toxic world. You need to carefully look at your home and remove toxins. You need to assess your drinking water. A water analysis can tell you how good the water in your home is and whether there are concerns about inorganic arsenic. Usually places that sell filter systems can advise you in that regard. Your drinking water should either be bottled pure water or else reverse osmosis water that can be part of a filter system in your house.

6.Vitamins and supplements have been shown to support your cell integrity and have anti-inflammatory and antioxidant effects that protect you from toxins. I discussed this in detail in my NetHealthBook under nutrition. For instance vitamin D3 in doses of 5000 IU or more and CoQ-10 are powerful anti-inflammatories and CoQ-10 is also an antioxidant and preserves mitochondrial function. High fish oil supplements (3 to 6 Grams per day) have anti-inflammatory effects and protect your cell membrane integrity. With these overlapping qualities of vitamins and supplements your body will be in a much stronger position to defend itself against the negative effects of toxins. When you take multivitamins, this translates into telomere lengthening of 5.1% (or converted into a survival advantage of 9.8 years when it is accumulated over a life time). Ref. 4 explains this in more detail.

7. Exposure to radioactive substances is a scary thought, but this is becoming more and more a reality, at least for those who live close to disaster areas such as the Fukushima site in Japan or the Chernobyl site in the Ukraine. But according to Dr. Apsley II low dose radiation that we have already received in the US and in Canada following the Fukushima disaster is equally disastrous (Ref.3). Many of the vitamins and supplements I have mentioned are also cell and mitochondria protective and will help with DNA repair following radiation damage, but you must avoid sugar and other refined carbs and starches to reduce the oxidative effect on cells and on LDL cholesterol to prevent premature aging and cell death. Ref. 3 contains a lot more detail about this and explains what specific supplements can be taken to detoxify your system from specific radioactive elements that function as free radicals. There are specific antidotes for radioactive iodine-129 and iodine-131, radioactive cesium-137 and others.

Conclusion

Many people shrug their shoulders when they hear that pollution has an effect on their lives. They feel that they are powerless and cannot do anything about this. The truth is far from this! Above I mentioned seven points that you can follow to counter toxins. On top of that you can get politically active and urge your government representative to create a nuclear free zone in your area. Ref. 3 contains compelling evidence why this is so important not only for us now, but for future generations and the future of mankind. We need to hold those who provide us with food and beverages accountable for the quality of these. Shrugging it off is not good enough. Get involved. Buy organic food. Avoid the section in the grocery store where sugar and high carb foods are sold. It’s good for your own health, but it will collectively change the mentality of the grocery store owners who will notice that they are stuck with the comfort foods that sold well in the past. This new trend will result in cheaper prices for healthy foods and more availability of organic food.

Live Your Best Life

While attending the 21st Annual World Congress on Anti-Aging, Regenerative & Aesthetic Medicine the audience was treated to a magnificent speech by the keynote speaker, who you all know from the TV show  “The Doctors”, namely the ER-doctor, Dr. Travis Stork.

He said that there are 4 main ingredients that are necessary to live the “best of your life”.

1. Healthy living starts in the kitchen

You want to make sure that you leave out unhealthy foods. This includes that you also need to cut out sugar. Be aware how important protein is, so you need protein with each meal. This includes legumes, fish, chicken, turkey meat and others. Saturated fat is essential, can improve your health and makes you feel full, but stay away from unhealthy, sugary snacks.

Snacks do not harm your health, but they must be healthy ones like nuts three times per day. To include nuts three times per day lowers your risk of dying by 39% and your rate of heart attacks by 52%.

In order to prove a point about cutting out junk foods, the TV producer convinced Dr. Stork to go on a junk food diet for 7 days to see what would happen. He gained 8 pounds after 6 days, his mood was getting subdued and he started to look forward to his next meal as if he was addicted to the junk foods. But suddenly he could not take it anymore and was concerned about getting sick from this experiment (rightfully so). He told his producer that he had to stop this experiment. He explained that most of his fat accumulation was happening in the abdominal area (visceral fat) and he showed a video that illustrated this further. He explained that the visceral fat is metabolically very active, produces inflammatory agents and causes changes in the heart vessels that eventually lead to heart attacks and strokes.

2. “I need you to start working out!”

We were designed to get moving. Our ancestors were gatherers and hunters, so they were constantly on the move. Our genetics have not changed, but our lifestyle habits are far removed: the sessile habits are not suiting us well healthwise. Translated into modern life this means: sit less; do gardening; use pacing as a technique to move when you are on the phone. Take the stairs instead of the elevator; walk (a minimum of 30 minutes three times per week). Personally, I like to add that our body never takes a holiday, so I think we should exercise 7 days per week.

3. Mind and body are connected

Stress can ruin your health. Happy people are 50% less likely to die prematurely. Laughter heals. A funny video was shared with the audience where a parent ripped a piece of paper into smaller and smaller pieces and the toddler watched with glee and laughed every time when the paper was ripped into two smaller parts. A service dog can be a great companion for disabled individuals, but pets have a positive impact on the health of any individual. They can be of help to reduce stress.

It is known that mind and body are connected. As a result, if your mind and body are balanced, your hormones get balanced and this helps to keep your metabolism in check. If your metabolism is balanced, you will avoid getting diseases like heart attacks, strokes, arthritis, and even cancer.

4. Make sure you get enough sleep

40% of people do not get enough sleep. You can change your sleep behavior. How do you do it?

a)    Have a consistent bedtime/waking time. Set your alarm clock to the same time every morning. Aim for 7 to 8 hours of sleep per night.

b)    Avoid late night caffeine as it prevents a good night’s sleep.

c)    Get active throughout the day; this will prepare you to get tired in the evening.

d)    Towards the end of the day have a to-do-list ready for the next day. This prevents tossing and turning and thinking about what you want to do the following day. You know that it is all written down on the list, so you can relax and get to sleep.

e)    No bright lights in the bedroom, no bright alarm clocks, no control lights of electronic gadgets and have light-blocking window coverings in place. Do not have a TV in the bedroom, also no cell phone, and stay away from the computer for 1 hour before your bedtime.

After you re-programmed your body and mind to a regular sleep rhythm, you automatically get tired when you should and your hormones and body chemistry find a new balance, which contributes to good health.

Dr. Stork stated that we all need to prevent disease. We do this by making health our hobby. There is no need to be obsessed about it. “Just live your best life!”

Conclusion

I summarized Dr. Stork’s presentation from the anti-aging conference, as it struck me how simple it really is to live a healthier life. If we all follow these simple steps, we are a long way into anti-aging, because it gives us the footing we need to further refine it from there.

In many previous blogs I have mentioned these 4 factors that are needed to slow down aging. However, there are other factors that may be needed like bioidentical hormone replacement when there are hormone deficiencies; detoxification, if there is evidence of toxicity; and vitamins and other supplements. Anti-inflammatory and antioxidant vitamins and supplements like CoQ10, vitamin D3 and omega3-fatty acid/DHA supplements are needed to keep LDL from getting oxidized as this is the reason why people die of heart attacks and strokes and get cancer.

I have recently written a book entitled “A Survivor’s Guide To Successful Aging” (being published at Amazon.com in March 2014), which explains the science behind why it is important to cut out sugar and starch. Sugar and starchy foods are the foods that oxidize LDL cholesterol, and ultimately it is the oxidized LDL cholesterol that causes deaths from heart attacks and strokes. In this text I have explained how proper nutrition, exercise, hormone rebalancing, supplements and lifestyle changes will allow you to prevent the major illnesses from setting in thus extending your life expectancy considerably. Included in the book is a chapter (written by my wife, Christina Schilling) that contains 7 days of recipes for breakfasts, lunches, dinners and desserts as well as snacks.

Pollution And Soaring Lung Cancer Rates

In early 1900 lung cancer was unheard of. This was before the cigarette industry started to mass-produce and market cigarettes.

However, ever since the arrival of the industrial revolution air quality has suffered. In China poor air quality has now reached such enormous values that the specialized cancer agency of the World Health Organization, the International Agency for Research on Cancer (IARC) has labeled poor air quality as one of the causes of lung cancer.

When you rank countries by average air pollution measurements, one sees that Europe, the US and South America overall have good ratings, whereas the Middle Eastern countries, China and India have poorer ratings.

However, when the pollution index of cities where the population is much denser than in the countries at large, are tabulated a much different picture emerges: Cities in Iran, India and Pakistan stand out as particularly bad followed by cities in China, Eastern Europe, Paris, London, Berlin, cities in California (the populous State), Chicago and New York.

Pollution does not stay local, but travels through the stratosphere around the globe. The result is that now 10 to 15% of lung cancer in the US occurs in patients who never smoked. This translates into 16,000 to 24,000 deaths annually of never-smokers in the US.

In certain cities such as Beijing the lung cancer rates have doubled in 9 years between 2002 and 2011. As this article shows lung cancer in never smokers can be caused from exposure to radon, to second-hand tobacco smoke, and other indoor air pollutants can also cause such cancers. But the outdoor air quality has been a problem ever since the industrial revolution, which started around Europe in the 1800’s and first part of the1900’s. In the latter half of the 1900’s much of the industrial wave has migrated to the Middle East, to India and China. But the air quality of the whole world has suffered as the jet stream and other air currents carry pollution in the stratosphere all around the globe.

Pollution And Soaring Lung Cancer Rates

Pollution And Soaring Lung Cancer Rates

History of pollution in various regions

1. In Germany’s  Ruhr district (“Ruhrgebiet”) in North Rhine-Westphalia, a highly populated industrial area, pollution reached a peak in the late 1950’s. From 1963 onward many of the coal mines, iron ore mines and other mineral mines closed down. 50 years ago the German Chancellor, Willy Brand was concerned about the environment and promised that blue skies would return to the Ruhr district again.  A special task force was initiated and maximally allowable limits were established for industries’ pollution emissions and enforced by the German government. Government and industry were co-operating in developing anti-pollution measures, which have cleared up a lot of the pollution since. With regard to car emissions lead free gasoline was introduced and carburetors ensured more complete burning of exhaust gases. This is now common and accepted anywhere except for diesel fume exhaust, which nobody wants to address despite proven carcinogenicity.

Now Germany is one of the leaders in green technology, which is also important for tourism.

2. England has its own legacy of pollution in soil and air from the industrial revolution. The soil of moorland, which soaked up acid rain for decades, is more acidy than lemon juice and it will take a long time despite industrial complexes having closed long time ago, before the soil quality will be returned to normal.

3. Hamilton in Ontario/Canada has had a longstanding pollution problem, which I witnessed from 1976 until my departure in 1978. It is well known that Stelco, the local steel plant downtown Hamilton is sending polluting emissions into the air. In 1976 a vising professor from Australia gave an interesting talk about a study that was done at that time regarding the risk of developing bronchogenic carcinoma (a synonym for lung cancer) in the immediate surroundings of the Stelco plant. He said that this was one of the first studies to show that the distance of people’s houses from the source of pollution mattered as that determined how concentrated the air pollution was (the closer the more polluted the air). This  affected cancer rates: they were much higher in the immediate surrounding of Stelco when compared to the average rate in the rest of Hamilton. This difference was very significant within a radius of 1 kilometer (= 0.62 miles) from the Stelco plant.

Just in May of 2013 the local cancer agency of Hamilton announced that the lung cancer rate in Hamilton was higher than elsewhere in Ontario because of a combination of poor air quality and of a higher percentage of people smoking. Then in August 2013 the city of Hamilton announced a new air pollution bylaw for stricter pollution measures to improve the air quality in the downtown area. It is just a pity that Hamiltonians had to wait until 2013 before the city approved an anti-pollution bylaw that could have been passed 50 years earlier like in Germany’s Ruhr district!

4. In 2008 Pittsburg, a former steel manufacturer town like Hamilton, Ont. outdid Los Angeles with regard to small particle air pollution.

Lung cancer prevention by the authorities

As mentioned before up o15% of lung cancer is caused by environmental exposure. So, we ourselves can only prevent 85% of lung cancer by not smoking and not exposing ourselves to industrial emissions or to smoke from incense. However, in many cities around the world you will get exposed to air pollutants that are well above the safe limits, so the risk of getting lung cancer from just breathing the air there can be much higher than in rural areas where there is no industry.

Technologies to control air pollution are widely available. We need to exert pressure on politicians to show leadership around the world. Government regulations to lower emission rates need to be put into place and inspectors need to ensure the rules and regulations are adhered to. Without reducing emissions of cancer producing gases and chemicals right at the source (open burning of cuttings in orchards or burning cut trees), cutting emissions of cars, planes, ships, diesel cars, locomotives, electric generator plants etc. the air quality will not improve. Despite some costs involved industry, governments and individuals have to work together to make clean air happen.

The residents of those countries that have low pollution values will not benefit, if pollution continues to occur in other parts of the world as it just travels in the stratosphere around the globe until it arrives right here at home! We need an international pollution police. Satellites can be used to monitor where pollution occurs and this can be followed up through the local regulatory bodies with penalties and remedial actions.

What can I do personally to prevent lung cancer?

1.The most obvious step is to quit smoking and ask smokers who come to your place to smoke outside (not in your home).

2.Consider moving away from the city, if the air quality is unacceptable to a place where there is low air pollution.

3.Vitamin D3 has been shown to prevent colorectal cancer, but as there are vitamin D receptors found on the surface of various cells in tissue around the body including the lungs, many researchers feel that this vitamin in higher doses (2000 IU to 5000 IU) has probably a wider applicability in preventing cancers, even lung cancer.

4.Cutting out sugar and adopting a Mediterranean type diet is a prudent thing to do; also cutting down your calories to the maintenance you need (mildly ketogenic diet). If you bought body composition scales, it would display what your daily calorie consumption is and you should not exceed this, or else you’ll gain weight. An aging man who is overweight will experience hormone changes as fat is being metabolized and the enzyme aromatase contained in fatty tissue will turn male hormones (testosterone, DHT, androstenedione) into estrogen. Estrogen (particularly estradiol) is a known carcinogen that has been proven to cause breast cancer in women and prostate cancer in men. However lung cancer is also being promoted in women by estrogen as discussed in this link. In men one needs to remember that lung cells have estrogen receptors and there is concern in aging men with higher estradiol levels that this can promote cell divisions in existing lung cancer. So, it is important to maintain a normal body mass index between 21 and 24 (well below 25.0 and well above 18.5, which are the official accepted limits). This way there is no problem with insulin resistance (too high an insulin level), and other metabolic substances (cytokines, growth hormone like factors and tumor necrosis factor-alpha from body fat) that are cancer promoting.

5. If testosterone deficiency is present, which is common in older men, testosterone will have to be replaced with bioidentical hormones. It is a myth that testosterone would cause prostate cancer. Testosterone in males is necessary to maintain a normal metabolism including the immune system, which then can fight lung cancer and any other cancers.

6. Exercise and reducing beef consumption are also often mentioned in terms of preventing lung cancer.

7. Here are several recommendations from the LifeExtension Foundation that I found very useful in terms of lung cancer prevention. This link shows that antioxidant vitamins such as vitamin C, alpha tocopherol, the minerals selenium and zinc are also helping to reduce the lung cancer rate. Drinking green tea has also been shown to be effective in a dose-response curve manner (more tea protecting more from lung cancer). Vitamin B12 and folate have been shown to reduce abnormal bronchial cell growth in smokers as shown by repeat bronchoscopy studies.

8. Those who have been smokers in the past and those who have been around heavy smokers for more than 10 years in the past should consider having a preventative bronchoscopy done by a lung specialist (also called respirologist or pulmonologists). This way any suspicious areas with precancerous lesions can be biopsied during the procedure and attended to.

Hopeful research for new lung cancer treatments

Lung cancer is a disease that is best prevented. Once a person gets lung cancer, the prognosis is still very poor. However, cancer researchers are getting close to newer treatments involving genetically modified T-cells (killer cells) as was recently achieved for leukemia. Similar research is going on regarding ovarian cancer, melanoma, lung cancer and pancreatic cancer.

Conclusion

It is not acceptable to let pollution take its course , the way politicians around the globe have handled this in the past 6 decades with a few notable exceptions mentioned. We all suffer a higher risk of getting lung cancer, even if we have been life-long non-smokers. Right now up to 15% of lung cancer in most populations are of this type. However, in Beijing this number is already much higher. The technology is available; Germany has led the way in the Ruhr district in the 1960’s and beyond. In my opinion the G8 meetings should have this high on their agendas and send technological aid to all the regions that have higher than the average world pollution index under the mandate of a special UN commission. This should be supported by the major industrial players with the knowledge that they will prevent the death of millions of potential consumers down the road, which will on the long-term pay off the relatively minor investment of installing pollution controls, before lung cancer levels rise even more.
