The greatest example of monounsaturated fat is olive oil, which is a prime component of the Mediterranean diet. Olive oil is a natural juice which preserves the taste, aroma, vitamins and properties of the olive fruit. Olive oil is the only vegetable oil that can be consumed as it is, freshly pressed from the fruit.

The beneficial health effects of olive oil are due to both its high content of monounsaturated fatty acids and its high content of antioxidative substances. Studies have shown that olive oil offers protection against heart disease by controlling LDL ("bad") cholesterol levels while raising HDL (the "good" cholesterol) levels. (1-3) No other naturally produced oil has as large an amount of monounsaturated as olive oil -mainly oleic acid.

Olive oil is very well tolerated by the stomach. In fact, olive oil's protective function has a beneficial effect on ulcers and gastritis. Olive oil activates the secretion of bile and pancreatic hormones much more naturally than prescribed drugs. Consequently, it lowers the incidence of gallstone formation.

Olive Oil and Heart Disease

Studies have shown that people who consumed 25 milliliters (mL) ( about 2 tablespoons) of extra virgin olive oil daily for 1 week showed less oxidation of LDL cholesterol and higher levels of antioxidant compounds, particularly phenols, in the blood.(4)

But while all types of olive oil are sources of monounsaturated fat, EXTRA VIRGIN olive oil, from the first pressing of the olives, contains higher levels of antioxidants, particularly vitamin E and phenols, because it is less processed.

Olive oil is clearly one of the good oils, one of the healing fats. Most people do quite well with it since it does not upset the critical omega 6 to omega 3 ratio and most of the fatty acids in olive oil are actually an omega-9 oil which is monounsaturated.
