Research shows that a diet high in trans fats is associated with an increased risk of heart disease. In fact, some scientists, such as Alberto Ascherio, M.D., of the Harvard school of public health, believe that trans fats pose more of a danger to your heart than the artery-clogging saturated fat found in bacon, butter, and lard. If trans fats were replaced by unsaturated vegetable oils, we would expect to see at least 30,000 fewer people die prematurely of heart disease each year. Dip, don't spread. Dipping your bread into seasoned olive oil isn't just trendy, it's healthful.
Olive oil is rich in monounsaturated fats, a type associated with a lower risk of heart disease.
Read the labels. Then buy something else. A hard and fat rule. If you do use margarine, choose a soft type instead of a stick. Smart Beat and Promise are two brands low in trans fats.
