The Fine Art of Finding the Fat

摘要

You think you're eating a healthful diet because you've limited your consumption of artery-dogging saturated fat. But if you are not minding your intake of another harmful fat called trans-fat, you might still be increasing your risk of heart disease. Indeed, whereas saturated fat raises the body's level of bad "LDL" cholesterol, trans-fat packs a double whammy by also reducing the good "HDL" cholesterol that protects against heart disease, according to Penny Kris-Etherton, professor of nutrition at Pennsylvania State University.
