Diabetes and sunlight. Is there a connection? By Marc Sorenson, EdD.
Diabetes associates with sunlight. Yet, please understand that lack of sunlight is not the primary cause of the disease. Nevertheless, sun exposure can act as an adjunct to the primary healing methods, which are nutritional changes and more exercise. My wife and I saw first hand, the efficacy of sunlight and good nutrition. During our 15 years at our former health institute, our clients lost more than 100 tons of fat. In addition, two-thirds of diabetic guests were free of all medication in less than two weeks. If clients stayed four weeks, there was about an 85% cure rate, and the remainder profoundly lowered medication. Sunny Southern Utah furnished the sunlight; we furnished the nutrition, exercise and expertise.
What is diabetes?
Diabetes is a disorder of chronically high blood glucose and it leads to blindness. It also leads to nerve damage, heart disease, kidney disorders, neuropathy and other maladies. Furthermore, it is so deadly that some experts believe it will ultimately destroy our health care system. Due to a change to a high fat, junk-food diet, this destruction of health care presently exists in China. In addition, diabetes was the seventh leading cause of death in the United States in 2017. Thus, 83,564 death certificates listed diabetes as the cause of death. Furthermore, it is important to understand that death certificates underestimate the carnage effected by diabetes. Most noteworthy is that diabetes contributes to far more than 83,564 deaths. Therefore, when researchers listed diabetes as the underlying or contributing cause of death, the number of deaths skyrocketed to 270,702.
Two forms of the disease: Both associate with lack of sunlight.
Diabetes comes in two forms: (1) Type-one diabetes occurs due to autoimmune response, thus damaging the insulin-producing islet cells. This damage consequently reduces production of insulin, which is responsible for removing glucose from blood and storing it in tissue. Only about 5% of diabetics are type-one. (2) Type-two diabetes, in which there is sufficient insulin, yet blood glucose remains high due to insulin resistance. This discussion involves type-two.
Most noteworthy, as with heart disease, a paucity of sunlight is not the primary cause. Rather, deleterious nutrition habits are the main reasons. These habits are principally high meat consumption, sugar consumption, egg consumption, low consumption of fruits and vegetables, and too many fried foods. In the case of type-one diabetes, milk consumption is probably the most important nutritional factor. Yet, sunlight may act as a prophylactic against both types of the disease. Especially relevant is that diabetes probably does not kill someone directly. Rather, it is the diseases resulting from diabetes, which lead to death.
The influence of sunlight on this disease.
There are several studies showing a relationship between type-two and sun exposure. Hence, one paper showed that blood-sugar levels were lower during summer, indicative of a protective effect of summer sun. Another, a meta-analysis, produced moderate evidence that recreational sun exposure associates with a reduced risk of type-two . The study materialized because the researchers observed that higher vitamin D levels associated with lower diabetes risk. Yet, vitamin D supplementation did not associate with lower risk. They hypothesized sun exposure could have influences unrelated to vitamin D, and such seems to have been the case.
Perhaps the most important investigation showed that women who had “active sun exposure habits” had a 30% decrease in the risk of type-two diabetes. It seems like being a regular participant in sunny activities is a good idea, no? Therefore, enjoy regular, non-burning sun exposure, avoid junk foods and prevent or heal this disease.
In research on rheumatoid arthritis, involving studies done on nurses, an interesting result emerged. It was found that among nurses 30-55 years of age who were assessed in 1976, and followed until 2008, there was an inverse association between sun exposure and the risk of rheumatoid arthritis. Those who were exposed to the greatest sun exposure had a 21% reduced risk of the disease. However, among nurses 25-42 years of age who were assessed in 1989 and followed until 2008, rheumatoid arthritis was not associated with greater sun exposure.
The authors of the researchers offered an explanation regarding the disparate results. They felt that the greater use of sunscreen among the younger subjects
may have made the difference.
I agree with that idea. Sunscreen would have decreased the availability of vitamin D production, which may have lead to the lack of a protective effect on rheumatoid arthritis among the younger nurses.
Rheumatoid arthritis is a disease which causes chronic inflammation of the joints, the tissue around the joints and even in certain organs in the body. It is an autoimmune disease such as lupus, multiple sclerosis and seasonal vitamin D declines may trigger it. Vitamin D is an anti-inflammatory hormone and declines in vitamin D levels, of course, are a result of decreasing sun exposure in colder seasons.
Arthritic joints carry another devastating side effect. Hip replacement surgery is often prescribed for arthritic conditions, and those people who go through total-hip-replacement procedures are 4.7 times as likely to have an ischemic stroke, and 4.4 times as likely to have a hemorrhagic stroke in the first two weeks post surgery. Those stroke risks remain elevated for 6-12 weeks. The term “ischemic” means producing a local deficiency of blood supply by obstructing blood flow.
I would be remiss if I did not also mention the transcendent importance of anti-inflammatory nutrition program. Sunlight is important but what you eat is critical. I would suggest that you google “anti-inflammatory diet.” Learn which foods (primarily fruits and vegetables) will help to decrease or prevent the inflammation that leads to RA. In the meanwhile, enjoy some safe, non-burning sunbathing.

Benefits of sun exposure by Marc Sorenson, EdD…
A new study on nutrition and skin aging corroborates what I have said previously in this blog: Sunlight is not the guilty party when skin problems occur; it is only one of many factors that influence the skin, and in some cases the influence is protective. And of course, sun exposure influence on the other organs of the body is overwhelmingly healthful.
To the extent that sun causes skin damage, it does so due to lack of proper nutrients in the diet, and there is little doubt that there will be some damage caused by sun exposure without proper nutrition. We eat too many toxic fats, too much meat and cheese, too much sugar and too many refined carbohydrates. At the same time we eat far too few vegetables and fruits, which can protect all the tissues in the body, including skin. Much of that protection is due to the high antioxidant levels of fruits and veggies. It is normal for humans to be exposed to sunlight, and it is equally normal for humans to take in the nutrients necessary to prevent skin damage, so that the sun may heal the body without harming our largest organ.
One of those antioxidants is astaxanthin, a new “superstar” in the antioxidant field. A new study shows that a group of mice that were exposed to Ultraviolet A Light (UVA,) lost water in the skin and developed wrinkles (both signs of skin aging). But in a group of mice that were also exposed to UVA and were supplemented with astaxanthin, no such skin aging occurred. This information demonstrates that poor nutritional habits may make sun exposure dangerous to the skin, because it is working without God’s natural balancing through nutrition. Our atrocious eating (and drinking) habits lead to skin damage, and sun exposure gets the blame.
Fruits and vegetable consumption help protect the skin, but other nutritional factors damage the skin. Alcohol consumption is one such factor; in one investigation, those persons who were in the highest quintile (fifth) of alcohol consumption were shown to have a 65% increased risk of melanoma.  Another indicated a 250% increased melanoma risk among those who consumed two or more alcoholic drinks per day, and a third demonstrated that those persons who consumed seven or more drinks per week had 64% greater risk of melanoma and a 23% greater risk of non-melanoma skin cancer when compared to non-drinkers. There are at least two other negative dietary habits that correlate to increased skin-cancer risk: first, the highest dairy-product consumption has also been shown to correlate to a 2½ times increased in risk of developing a non-melanoma carcinoma (common skin cancer). Secondly, the types of fats we consume are exceptionally important. Fats we consume in junk foods are deadly, both for overall health and for skin cancer. They are filled with free-radical molecules that wreak havoc on the skin; if we eat such fats without massive quantities of colorful fruits and veggies, we will be much more susceptible to skin damage and potential cancers of all kinds.
Sun exposure is absolutely essential for human health; but to protect yourself against any damage to the skin, eat the foods that were made for humans!

A new article on November 30, 2015, from the Daily Mail, discusses breaking research on the association between ED and vitamin D. The research from Johns Hopkins University, by Dr. Erin Michos and her colleagues, was conducted on 3,400 men over age 20, 30% of whom were vitamin D deficient, and 16% of whom reported symptoms of ED. Men with Vitamin D deficiency were 32% more likely to suffer ED than those whose levels were sufficient.
Although I, along with Dr. Grant, were the first to hypothesize that vitamin D deficiency could lead to ED, I have moderated my opinion somewhat. It is entirely possible that higher vitamin D levels are really a surrogate measurement for sunlight exposure. Although vitamin D probably has a positive affect on ED, the UVA portion of sunlight has a nearly immediate effect in dilating the blood vessels through the production of nitric oxide (NO), which is absolutely necessary for producing an erection. Viagra and other ED drugs work by inhibiting the breakdown of NO, which keeps NO in circulation for a longer period. But, they don’t always work and can have many deleterious side effects.
My hope is that research will be done to determine the effectiveness of sunlight exposure in alleviating the condition. Of course, the underlying cause of ED is consuming foods that occlude the arteries. Sunlight and/or vitamin D serve as palliatives to that occlusion, as do the ED drugs. A nutrition program filled with colorful fruits and vegetables,[i] along with ample sunlight exposure, would, in my opinion, produce the very best results in mitigating or perhaps reversing the disease.

Whereas melanoma, the deadly skin cancer, is inversely associated with sunlight exposure (more sunlight exposure, less melanoma) the same is not true for NMSC, which is directly associated with sunlight exposure. It is a rarely fatal disease unless the immune system is compromised due to other diseases or anti-rejection drugs. It has been shown that NMSC associates to a lower risk of melanoma and many other cancers.
I am not suggesting that we contract NMSC in order to prevent melanoma. Correct nutritional habits can also reduce the risk of both NMSC and melanoma, and it should be remembered that in the case that someone contracts an NMSC, it can be easily removed. Melanoma, however, can be deadly. The best bet is to eat wisely and obtain plenty of regular sun exposure so that risk of melanoma is dramatically decreased.
NMSC is often used as a marker for sunlight exposure and is compared with various diseases beyond cancer to determine if sunlight exposure associates to those diseases. Dr. Bill Grant just sent me a paper showing that among people over 70 with NMSC, the risk of Alzheimer’s disease (AD) is profoundly decreased; in fact those with NMSC had a 79% reduced risk of Alzheimer’s. Or stated another way, those without NMSC had about five times the risk of the disease. Of course, this demonstrates the value of sunlight in reducing AD.
Let’s protect our minds as we age by getting plenty of non-burning sunlight! Search the Sunlight Institute site to learn more about how Alzheimer’s is influenced by sunlight and vitamin D.
