Peeling is unnecessary, Winter says. Treat it like meat. When you're done chopping the vegetable, put the knife and cutting board in the dishwasher, just as you would after cutting raw meat. Don't use them for other foods until they've been washed. Margarine is loaded with trans fatty acids, a type of fat that's formed when vegetable oils are processed to make them solid at room temperature.
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.
