Sunlight the Great Healer

The USA's Environmental Protection Agency's (EPA) advice to avoid sunlight is believed by many to be based on junk science. The Townsend Letter (the examiner of medical alternatives), January 2004, in an article entitled, The Healing Power of Full Spectrum Lighting, explains why.
"The phobia arose after investigators anaesthetized animals, propped their eyes open and shined intense UV light into them; this damaged their retinas. Excessive exposure to one kind of ultraviolet (short wave, germicidal UVC) can damage tissue. But the EPA makes the ridiculous leap from that truth to the conclusion that we should avoid all UV. UVC is not present increasingly in sunlight... In fact, trace amounts of UV radiation in natural daylight are required for physical and mental health, civilized behavior, muscle strength, energy, and learning.
Sunlight in moderation improves immunity and stimulates our metabolism while decreasing food craving and increasing our intelligence. Those words were taken from the book Sunlight by Zane R. Kime, M.D., M.S., where he backs this statement up with scientific research.
Brian Clement, Director of the Hippocrates Institute, says that sunlight is the most powerful booster of the immune system that he is aware of.
In his book, Sunlight, Dr. Kime explains the link between nutrition and sunburn. "Unless one has proper diet, sunlight has ill effects on the skin. This must be emphasized: sunbathing is dangerous for those who are on the standard high-fat American diet or do not get an abundance of vegetables, whole grains, and fresh fruits. Those on the standard high-fat diet should stay out of the sun and protect themselves from it; but at the same time they will suffer the consequences of both the high-fat diet and the deficiency of sunlight." Dr. Kime also summarizes several excellent studies which conclude that sunlight is a much better source of vitamin D (which more closely resembles a hormone) then the kind added to enriched foods, especially cow's milk.
My personal experience supports Dr. Kime's thesis. Before I changed my eating habits from the Standard American Diet (S.A.D.) to the health- promoting lifestyle that I practice today, I could not spend much time in the sun without sunscreen or I would become sunburned. Ever since my positive lifestyle change, I have been able spend as much time as I wish in full sun, without sunscreen, and never burn! After researching the matter, I found that an increased dietary intake of vitamins and other nutrients, and an avoidance of free-radical forming foods, has been scientifically shown to have that effect on humans.
