The main type of fat found in all kinds of olive oil is monosaturated fatty acids (MUFAs). MUFAs are actually considered a healthy dietary fat.

The consumption of olive oil may help lower your risk of heart disease by improving related risk factors. For instance, MUFAs may lower your total levels of ''bad'' cholesterol and increase the levels of ''good'' cholesterol. MUFAs may also help normalize blood clotting. Some research also indicated that MUFAs may also benefit insulin levels and blood sugar control, which can be especially helpful if you have diabetes.
Choose MUFA-rich foods such as olive oil instead of other fatty foods — particularly butter and stick margarine — not in addition to them. And remember that you can not make unhealthy foods healthier simply by adding olive oil to them.
