Olive oil is a vegetable oil extracted from olives, the fruit of the olive tree. It is commonly used in cooking, salad dressings, dips, cosmetics, and pharmaceuticals.
Olive oil is rich in monounsaturated fats, which have been linked to a number of health benefits, including reducing the risk of heart disease, stroke, and type 2 diabetes. Olive oil also contains antioxidants, which can help to protect cells from damage.
