The higher the vitamin D level, the lower the risk of diabetes

It will appear that all of my news posts are related to vitamin D, but the news lately just don’t stop mentioning it in various contexts. Why is there such a surge of new results with vitamin D, it’s difficult to say.   Harvard Health Letter has reported a recent study published in PLOS One, where it was shown that higher levels of vitamin D were correlated with a lower diabetes risk.  Among 900 older adults, people with vitamin D levels of 30 ng/ml or more had one-third the risk for developing diabetes, while people whose D levels were 50 ng/ml or more had one-fifth the risk. The study does not show a causal relationship, just a correlation, so this is still not a proof that taking vitamin D supplements would reduce risk of diabetes, but there is a possibility.
