Vitamin D has been in the news lately, as most people are deficient. If you don’t get out in the sunshine, you probably have low levels—unless you supplement.
Getting the optimum amount of vitamin D helps prevent everything from cancer to heart disease, primarily due to its immune-boosting power.
New studies suggest that those who have high levels of D are also about 40 percent less likely to develop type 2 diabetes than those with lower levels, according to the July ’11 Bottom Line Health. D apparently can reduce insulin resistance, a key cause of diabetes.
