Trans fat substitutes: Not a slam dunk

Avoiding trans fat? Good for you. But just because a food is free of trans fat doesn't mean it's automatically good for you. Some trans fat substitutes, such as coconut and palm oil, contain a lot of saturated fat. A little saturated fat is OK, but too much raises your bad cholesterol. Monounsaturated fat, found in olive, peanut and canola oils, is a healthier option.
