New research shows that a Mediterranean diet may reduce the risk of breast cancer.

The study was conducted in Spain and it asked women to follow a Mediterranean diet that was high in extra-virgin olive oil. The ones who consumed olive oil were 68% less likely to develop breast cancer.

4,152 post-menopausal women who had never had breast cancer were examined in the study. They split up into three groups–Mediterranean diet, Mediterranean diet with olive oil and simply reduced fat.

Previous studies have shown that the Mediterranean diet may have anti-tumor effects. Extra-virgin olive oil contains polyphenols, which have anti-cancer effects.
