Vitamin D & diabetes.

People with higher blood levels of vitamin D had a lower risk of Type 2 diabetes in the largest study to look at the link.

Researchers compared levels of vitamin D in blood samples taken in 1990 from roughly 1,200 participants in the Nurses' Health Study, half of whom were later diagnosed with diabetes and half of whom were not.

Women with the highest vitamin D blood levels (they averaged 33 ng/mL) were half as likely to get diabetes as those with the lowest levels (they averaged 14 ng/mL).

What to do: Scientists won't know if vitamin D lowers the risk of diabetes until large-scale trials comparing the vitamin to a placebo are done. in the meantime, it's worth taking 800 to 1,000 IU a day of vitamin D if you're over 60 and 400 IU a day if you're younger.
