I’ve harped on the need for additional vitamin D, from both sunlight and diet, for years. Since I’ve written extensively on the subject in the past, I’ll make this rather brief.

In addition to all the problems most commonly associated with vitamin D deficiency (immune problems, chronic muscle and joint pain, various cancers, hip and other bone fractures, osteoporosis), it now looks like it may be associated with insulin resistance--which, as you know, can lead to diabetes.

In one study, researchers at the University of California found that low vitamin D levels resulted in insulin resistance and improper function of the pancreatic cells that help produce insulin.

If you, or your family, have a history of type 2 diabetes, insulin resistance, or hypoglycemia (low blood sugar), then adequate amounts of vitamin D are even more important. At least 30 minutes a day in the sunshine (without a sunscreen) would be helpful. A daily multivitamin that includes a minimum of 400 IU of vitamin D is also a useful start toward my recommended daily amount of 2,000 to 5,000 IU. (Am J Clin Nutr 04;79:820-825)
