Try to exercise at least a half hour three times a week. Just like with cholesterol, there are good fats and there are bad fats. Saturated fat , which is often found in animal products and tropical oils, raises your cholesterol. Canola and olive oil are good sources of monounsaturated fats. Polyunsaturated fat can lower your cholesterol, but too much can increase your risk for cancer, so it's a good idea to limit them if you can.
Hydrogenated fats are really unsaturated fats with hydrogen, which increases firmness.
Unfortunately, it also increases saturation, and that's bad. You'll want to limit hydrogenated fats in your diet. Fast food, margarine, peanut butter and snack crackers all contain hydrogenated oils. Smoking Smoking narrows your blood vessels, elevates blood pressure, and raises LDL cholesterol. If you smoke, quit now.
