Researchers at Tufts analyzed 19 studies and found that people with a daily intake of vitamin D of more than 500 IU had a 13% lower risk of type 2 diabetes than people with a 200 IU daily intake. When they looked at blood levels, they found those with the highest blood levels (more than 25 ng/ml) were 43% less likely to develop diabetes.

In a similar analysis of 23 studies, published in the August, 2011 issue of the British Journal of Nutrition, Australian researchers found that those with the highest blood levels of vitamin D were 50% less likely to develop type 2 diabetes than those with the lowest levels.
