15. Olive oil
Research has shown that people in countries where olive oil is used instead of other types of oils tend to have lower rates of cancer and heart disease. This is believed to be due to olive oil's many good components: oleic acid, an anti-inflammatory fatty acid which protects against oxidation and polyphenols and antioxidant compounds that prevent inflammation and oxidation.
Use virgin or extra virgin olive oil – they're higher in antioxidants. Olive oil can be used in cooking or to make salad dressing, as a dip for bread and as a marinade for vegetables.
