More on health benefits of Vitamin D

Almost everyone needs more of the sunshine vitamin USNews&WR 12/18/06 "A single nutrient that keeps bones strong, wards off diabetes, and protects against tuberculosis, cancer, colds, and the flu. Sound too good to be true? There's more: It's free. But you're almost certainly not getting enough...Prior to the industrial revolution, humans had no trouble getting an abundance of the sunshine vitamin; a mere 10 to 15 minutes outdoors at midday gives the average fair-skinned person 10,000 international units. That's far above the government's dietary recommendations of 200 IUs a day up to age 50, 400 IUs to age 70, and 600 IUs over 70... A review of more than 100 studies on vitamin D and respiratory diseases, published in the current Epidemiology and Infection, found that low levels probably allow the viruses to penetrate the immune system...With cancer, it's thought that vitamin D might prevent tumors from rapidly growing by controlling the expression of certain genes that regulate cell division"

This is a vitamin D renaissance. More on Vit D later.
