Understanding Fat
Don't fear -- or misunderstand -- fat any longer
by Lisa Holl
People often cringe when they hear the word fat. That may be because they misunderstand it. Experts at Harvard University point out: "The total amount of fat in the diet, whether high or low isn't really linked with disease. What reallt matters is the type of fat in the diet."
In fact, some types of fats, including most unsaturated fats, reduce the level of cholesterol in one's blood. Plant products like vegetable oils, nuts and seeds all contain these "good" fats. Omega-3, a fatty acid found in fish, may even reduce the risk of heart disease. The American Heart Association suggests eating two servings of fish a week for this reason.
Other types of fats should be avoided. Saturated fats increase blood cholesterol level, which can increase one's risk of heart disease. Meat, dairy products and eggs all contain this "bad" fat and should be consumed in moderation.
Trans fats, which are processed, unsaturated fats found in deep-fried dishes, many baked goods and margarine, should be avoided completely. Trans fats carry an even greater ridk of heart disease than saturated fats.
So, replace the bad fats with the good gats in your diet, and enjoy a healthier life.
