After the "fat-free" frenzy of years past, it's no wonder that some people are scared off of eating any fats. But look around... did the fat-free trend solve the obesity problem? Nope... not at all. That's because food manufacturers raced to label their foods as "fat-free" in big, bold letters on the front of the packages, but they failed to mention other unhealthy ingredients such as high sugar or high sodium or unpronounceable chemicals that really have no place in our diet whatsoever.

The truth is we need fat in our diets. (Not as much as most people consume, of course, but we do need it.) Our bodies can generate a certain amount, but the rest must be consumed. The trick is eating foods prepared with the good fats. That's right... I said good fats. A recent survey revealed that more than half of Americans have no idea that there are some fats you should be including in your diet. To help people better differentiate between good and not-so-good fats, the American Heart Association has launched Face the Fats.

There are four types of fats: saturated fats, trans-fats, monounsaturated fats, and polyunsaturated fats. While all four varieties have the same number of calories (9 calories per gram of fat), they have different effects on health. Saturated and trans-fats are the culprits to avoid -- they can raise your "bad" cholesterol (LDL). But monounsaturated and polyunsaturated fats are beneficial for health when consumed in small amounts; they help reduce cholesterol levels and provide essential fatty acids (omega 3 and omega 6) that your body needs but can't generate on its own.
