Question: “I recently read that selenium supplements cause cholesterol numbers to increase? Do you have any information on this?”—Carolyn, via e-mail
Answer: This antioxidant mineral is needed in small amounts. So far, there’s just not enough information yet about selenium supplements and its effect on heart disease. (However, large studies so far have found alarming results for men taking the mineral supplement: not only did supplement takers in the study not have less prostate risk, but their diabetes risk was higher.) If you don’t have a condition that requires nutrient supplementation, choose food for your nutrients. Besides the fact that it tastes better, you’re likely gaining fiber, minerals, vitamins, and a host of other compounds that may bolster health.
