10. Olive oil
The monounsaturated oleic acid (say that three times fast) found in olive oil protects your heart and significantly lowers your risk for cardiovascular disease and stroke.
Add it to your diet: Drizzle on your salads and use it in cooking, but make sure you’re using the right type. To get all of this oil’s antioxidant and anti-inflammatory benefits, purchase 100 percent extra virgin olive oil (organic if possible).
