Olive oil's health benefits (Healingdaily.com)
The greatest exponent of monounsaturated fat is olive oil, and it's is a prime component of the Mediterranean Diet. Olive oil is a natural juice which preserves the taste, aroma, vitamins and properties of the oil 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. 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.
