Vitamin D is officially having a moment. To date, there is some research that suggests D can help build bones, strengthen your immune system, and lower the risk for diabetes, cancer, high blood pressure, and heart and kidney disease. Yet, as has been widely reported, half or more of all children and adults may be vitamin D deficient. (You can read more about vitamin D and its effects in Vitamin D: Sunshine and So Much More, and in Vitamin D, Miracle Drug: Is It Science or Just Talk?) As a result, interest in vitamin D is at an all-time high — which is great news. Public interest and media coverage have led to increased individual vitamin D testing, increased discussion among medical professionals and, perhaps most important, to more funding for reliable studies to determine just how important, effective and safe it really is. In the meantime, there are at least a dozen new vitamin D books out this year, and there's much discussion about how exactly to get more of this currently in vogue vitamin. (In addition to supplements, the easiest way to get vitamin D is from sunshine. You can also get it from fortified milk; oily fish such as salmon, sardines and mackerel; eggs (free-range have more D); and shiitake mushrooms.)
