Olive oil is a versatile and widely used cooking oil obtained from pressing olives, the fruit of the olive tree. Recognized for its health benefits and culinary versatility, olive oil comes in various grades, such as extra virgin, virgin, and regular (pure) olive oil, each with different levels of processing and flavor profiles. Extra virgin olive oil, made through a cold-press process, is considered the highest quality and retains the most natural flavors and beneficial compounds. Olive oil is prized for its rich, fruity taste, high monounsaturated fat content, and antioxidant properties, which contribute to its reputation as a heart-healthy option. It's used in cooking, dressings, marinades, and dips, and is a fundamental ingredient in Mediterranean cuisine.
