Higher blood levels of vitamin D may reduce the risk of insulin resistance. Tufts University researchers studied 808 men and women enrolled in the Framingham Offspring Study, testing blood levels of 25-hydroxyvitamin D and markers of insulin resistance, a risk factor for type 2 diabetes. They found that those with the lowest levels of D were much more likely to have markers for insulin resistance than those with the highest D levels, even after adjusting for other variables.
