Extra virgin olive oil - long been associated with a healthy diet - possesses many protective qualities against disease. All types of olive oil have healthy fatty acids, protecting against cardiovascular disease and diabetes but only extra virgin olive oil is rich in antioxidants. They are biologically active and lower the risk of chronic disease. The slight burning sensation from extra virgin olive oil denotes a high content of one, oleocanthal.

A multitude of scientific studies support the health benefits. Published in 2022, a Harvard (T.H. Chan School of Public Health) US longitudinal study found significantly lower mortality rates associated with high use of olive oils, compared to other fats.
