A new study by the The Harvard Medical School shows that replacing saturated fat with polyunsaturated fat can increase your body’s level of good cholesterol. The study shows that for every 5% increase in polyunsaturated fat consumption there was a 10% fall in heart disease.
According to the American Heart Association, foods high in polyunsaturated fats include soybean oil, corn oil, and safflower oil, as well as fatty fish like salmon, mackerel, herring and trout. Other sources include nuts and seeds like walnuts and sunflower seeds. Monosaturated fats are equally good for you. Foods high in monosaturated fats include olive oil, peanut butter, and avocado.
