Refined Olive Oil And Virgin Olive Oil

Olive oil is a liquid fat obtained from olives, the fruit of the olive tree. Refined olive oil is processed to remove impurities and defects, resulting in a lighter color and milder flavor. Virgin olive oil is less processed and retains more of the olive's natural flavor and color.

Olive oil is used as a cooking oil for sautéing, roasting, and frying, as well as a base for salad dressings and marinades. Manufacturers use it for its flavor, texture, and ability to carry other flavors. It is commonly found in salad dressings, sauces, and vegetable and cooking oil blends.

Olive oil is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of monounsaturated fats, which are considered heart-healthy when consumed in moderation as part of a balanced diet. The World Health Organization (WHO) has not classified olive oil itself, but has noted the health benefits of diets rich in monounsaturated fats. Evidence suggests that replacing saturated fats with unsaturated fats, like those in olive oil, can help lower LDL cholesterol levels.
