Where you find them: In animal sources such as meat (beef, lamb, pork and poultry with skin), cream, butter and other dairy products made with whole or even ''reduced fat'' 2 percent milk.

How to spot them: Solid at room temperature.

Why they're bad: They raise low-density lipoprotein (LDL) or ''bad'' cholesterol levels, leading to increased risk of heart disease and stroke.

AHA recommends: Less than 7 percent of total daily calories should come from saturated fats. Cut down by substituting low-fat or fat-free dairy products for high-fat dairy in your favorite recipes. Eat lean meats, such as chicken breast or fish, or replace meat entirely with beans or legumes.
