Olive oil is the natural oil extracted from olives, the fruit of the olive tree. About 14% of the oil is saturated fat, whereas 11% is polyunsaturated, such as omega-6 and omega-3 fatty acids. But the predominant fatty acid in olive oil is a monounsaturated fat called oleic acid, making up 73% of the total oil content.
Studies suggest that oleic acid reduces inflammation and may even have beneficial effects on genes linked to cancer.
Monounsaturated fats are also quite resistant to high heat, making extra virgin olive oil a healthy choice for cooking.
