Tip: The body doesn't produce fatty acids naturally, so you must add them to your diet. If you're like most people, you are eating far too many inflammation-promoting omega-6 fatty acids and far too few omega-3s. What to do? In addition to eating more fish, add flaxseed to your cereal and smoothies and chia seeds to stir-fries and salads. Both are stuffed with omega-3s (and have little taste).

How much should you eat? According to the Cleveland Clinic, one to two tablespoons is a healthy daily dose, though it cautions that patients on blood thinners should not take chia seeds. —Margery D. Rosen
