The FDA now requires statin drug labels to warn of the risk of developing diabetes. The most effective statin, Crestor, probably carries the greatest risk. Many alternative doctors prefer to use red rice yeast instead of the synthetic drugs, because they seem to be similarly effective at lowering cholesterol and reducing inflammation with much fewer side effects. I also like to add cinnamon pills, which not only lower cholesterol but also reduce blood sugar and insulin resistance.
