BEST DIET

Report #7278

Strict low-fat diets are out. Researchers at Harvard Medical School show that a heart attack preventing diet is low in saturated and partially hydrogenated fats but does not restrict polyunsaturated and monounsaturated fat. Lots of fruits, vegetables,whole grains and beans and little of everything else.

There are four types of fat: saturated, polyunsaturated, monounsaturated and partially hydrogenated. Restrict saturated fats in meat, chicken, diary products and eggs. When you take in more calories than your body needs, your liver breaks down saturated fats into acetone units that it uses to raise cholesterol. Eat fruits and vegetables. They are loaded with polyunsaturated and monounsaturated fats. When fresh vegetable oils are substituted for saturated fats, they lower cholesterol significantly. However, when you extract vegetable oils, the polyunsaturated and monounsaturated oils turn rancid very quickly, so manufactures change these chemicals to partially hydrogenated fats that have a longer shelf life. These oils raise cholesterol and increase your chances of getting a heart attack and certain types of cancer/ and are found in prepared foods such as bakery products and stick margarines. Eat lots of fruits, vegetables whole grains and beans and fish and restrict fats, oils, meats, chicken, diary products, eggs, stick margarines and prepared foods made from hydrogenated fats.
