Diabetes and sun exposure By Marc Sorenson, EdD.
Diabetes is a disease of chronically high blood glucose leading to blindness, nerve damage, heart disease and numerous other maladies. Diabetes comes in two forms: (1) Type-one, in which there is damage to the islet cells of the pancreas. This is usually due to an autoimmune response, and the damage prevents production of insulin responsible for removing glucose from the blood. (2) Type-two, in which insulin is produced, but blood glucose remain high due to insulin resistance. In this article, we will discuss type-two, which is by far the most common type. As with heart and vascular disease, we must realize a paucity of sunlight is not the cause of either type of diabetes; rather it is caused by deleterious nutrition habits, primarily high meat consumption,   sugar consumption,  egg consumption, low consumption of fruits and vegetables, and too many fried foods. In the case of type-one, milk consumption may be the most important nutritional factor. However, sunlight may act as a prophylactic against either type of diabetes. With either type of diabetes, it is not usually the diabetes that kills, but other diseases resulting from it.
There are several studies showing a relationship between type-two diabetes mellitus (DM) and sun exposure or UVB exposure. One paper showed blood-sugar levels were lower during the summer, and another demonstrated exposure to sun lamps increased insulin secretion. It has also been found there is a direct and significant association between low 25(OH)D levels (a surrogate measure for low sun exposure) and increased risk of type-two.
In addition, a meta-analysis produced moderate evidence that recreational sun exposure is associated with a reduced risk of type-two. The study was undertaken because of the observation by researchers showing that although higher 25(OH)D levels were consistently associated with a lower risk of diabetes, supplementing 25(OH)D had shown no such effects. They hypothesized sun exposure could have influences not related to vitamin D, and such seems to have been the case.
Another of the more important investigations showed that women who had “active sun exposure habits” had a 30% reduced risk of type-two.
Diabetes is increasing very rapidly and may someday overwhelm the health-care system. In my opinion, it is the most easily reversed of all degenerative diseases, so this is a tragedy. Proper nutrition, exercise and safe sun exposure can prevent almost all type-two diabetes. At our former resort, about two-thirds of type-two diabetics were free of all medication in two weeks. It is a totally unnecessary disease. If you don’t have it, prevent it. If you have it, reverse it. Start today.
