Olive oil is a liquid fat obtained from the fruit of the olive tree, primarily grown in the Mediterranean region. It is produced by pressing whole olives and extracting the oil, which can vary in flavor, color, and aroma depending on the type of olives used and the extraction process. Olive oil is commonly used in cooking, salad dressings, and as a dip for bread. Rich in monounsaturated fats, olive oil is often praised for its health benefits, including potential heart health advantages and anti-inflammatory properties. It is also a key ingredient in the Mediterranean diet, which emphasizes whole foods and healthy fats.
