Vitamin D could be weapon against type 2 diabetes

A review of clinical trials has found that higher vitamin D intake was associated with a 15 percent decreased likelihood for developing type 2 diabetes in adults with prediabetes. The review is published in Annals of Internal Medicine.

Vitamin D is a fat-soluble vitamin available in or added to some foods, as a supplement, or produced by the body when ultraviolet rays from sunlight strike the skin. Vitamin D has many functions in the body, including a role in insulin secretion and glucose metabolism. Observational studies have found an association between having a low level of vitamin D in the blood and high risk for developing diabetes.
