Cooking:

Olive oil is a great source of oleic acid, an anti-inflammatory fatty acid. The monounsaturated fat in olive oil protects against oxidation. Olive oil is rich in polyphenols and antioxidant compounds that prevent inflammation and oxidation.
Studies show that populations that use large amounts of olive oil instead of other oils have lower rates of heart disease and cancer.
Buy virgin or extra virgin olive oil because they are higher in antioxidants. Use olive oil to make salad dressing, in cooking, for dipping bread or for marinating vegetables.
