Q. What are trans fats and why are they so bad for you?
A.Trans fats, also known as trans fatty acids, are man-made fats produced when vegetable oils are hardened into margarine or shortening. Trans fats are also used in many fried foods and processed baked goods.
Trans fats are bad for you because they may increase your LDL, or "bad" cholesterol, while lowering levels of HDL, or "good" cholesterol. This can lead to increase risk for heart disease. In addition, trans fats have also been linked to an increased risk for Type 2 diabetes and certain cancers.
Starting Jan. 1, 2006, the FDA is requiring all packaged foods to list trans fats on the Nutrition Facts label. Currently the only way to spot trans fats in your food is to read the ingredients list and look out for shortening or partially hydrogenated oil.
