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
