Extra virgin olive oil, the cold-pressed result of the first pressing of the olives, is only 1 percent acid. It’s considered the finest and fruitiest of the olive oils and is therefore also the most expensive. Extra virgin olive oil can range from a crystalline champagne color to greenish-golden to bright green. In general, the deeper the color, the more intense the olive flavor. After extra virgin, olive oils are classified in order of ascending acidity.
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.
Studies have shown that people who consumed 25 milliliters (mL) – about 2 tablespoons – of virgin olive oil daily for 1 week showed less oxidation of LDL cholesterol and higher levels of antioxidant compounds, particularly phenols, in the blood.
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.

Thanks for all the great advice on olive oils! My grandfather owns an olive farm and wants to start turning them into olive oils. Up until now, he has just been selling the olives but he would make a lot more money if he took it one step further! I had no idea that olive oil is one of the more healthy oils available. Thanks again!
