Known far and wide as “vitamin D,” the amazing benefits of this life-critical hormone are little recognized or understood.
As author Krispin Sullivan has discovered, recently published research links insufficient vitamin D with an array of ailments, including Syndrome X (hypertension, obesity, diabetes, and heart disease); senile cataract; osteoporosis; build up of calcium deposits in the arteries; cardiovascular disease; and autoimmune diseases such as M.S., Sjögren’s syndrome, rheumatoid arthritis, thyroiditis, and Crohn’s disease. D deficiency has also been mistaken for fibromyalgia and chronic fatigue. Breast, prostate, skin, and colon cancers have a strong association with low levels of D, and low levels may even contribute to depression. Why is it that so many of us are not getting the D we need?
Even elementary school children know that vitamin D “comes from the sun,” actually a particularly narrow band of sunlight called UV-B. Historically, our ancestors spent more time in the direct sun. Distributed about the globe, their skin pigmentations appropriate to absorbing and processing the amount of UV-B (the precursor of D) available in their part of the world, the wild game they consumed ranged freely under the sun and contained more of this vital hormone stored in its fat
Today, migration and dietary changes have meant that we no longer receive vitamin D in doses calibrated by nature. Additionally, the clothes we wear and our glass windows separate us from the world, screening out nearly all available UV-B. With rampant fear of skin cancer, and ever-increasing sales of ever more powerful sunscreens, sunshine has become a dirty word, and millions now suffer deficiencies of vitamin D.
Naked at Noon explores what some might consider the “silver bullet“ of good health. Catching some rays, it tells us, is really good for us. Naked at Noon tells us which ones we need, and how much is optimal for each skin type. It provides information on testing for levels of vitamin D, and also discusses the pros and cautions about D and related supplements—calcium and magnesium.
