Inflammation is a condition that damages healthy tissue, raises blood pressure, and can potentially encourage cancer cells to grow, says Rachel Beller, R.D., president of
Beller Nutritional Institute. Since consuming too many omega-6 fatty acids (in relation to omega-3s) can increase the risk of inflammation, swap omega-6-laden soy, sunflower, corn, cottonseed, safflower. and mixed vegetable oils with extra virgin olive oil, which is rich in omega-3 fatty acids. For higher-heat cooking or a more neutral taste, use organic expeller pressed canola oil (those sold in glass bottles are the best).
