Abstract Inadequate vitamin D nutritional status is prevalent worldwide and has been associated with autoimmune disorders, heart disease, deadly cancers, insulin resistance, inflammation, neurological disorders, adverse outcomes in pregnancy, and increased risk for mortality.

Diabetes prevention is a public health priority. Vitamin D supplementation may help prevent the development of diabetes in persons at increased risk. We performed a meta-analysis of controlled clinical trials that assessed glycemic outcome measures among adults at risk for type 2 diabetes, including prediabetes, overweight, or obesity. We searched PUBMED/MEDLINE, CINAHL, and Google Scholar databases for trials published prior to April 2017.

We interviewed Dr. Michael Holick on why sunshine is good for you and the best source for vitamin D. Here is what he said: In your opinion what is the root cause of vitamin D deficiency? The 2 major reasons for the global D deficiency epidemic are the lack of understanding that very few foods naturally contain vitamin D and that sunlight has been and continues to be a major source for vitamin D worldwide.
