Olive Oil Side Effects & Benefits

Olive oil has been around for centuries and offers many benefits and few side effects. It can be used for cooking, housekeeping and as a personal beauty or health supplement. Daily intake of the right type of olive oil will even help prevent heart disease and can lower your risk of colon cancer.

Facts

Olives are pressed to yield olive oil. The oil retains all the vitamins and nutrients of the olive, because it does not need processing. Once oil is pressed from the olive, it can be ingested as is.

Olive oil is high in monounsaturated fatty acids and antioxidants. The oil also contains high-density lipoproteins (HDLs) that are vital in controlling low-density lipoproteins (LDLs). LDLs raise your cholesterol level and can be harmful to your health, but HDLs keep these levels in check.
