While omega-3 fatty acids help ease inflammation, omega-6 fatty acids may do the opposite. They're found in oils like corn, safflower, peanut, and vegetable. And they also show up in a lot of snack foods. An easy fix: Clear your pantry of chips, crackers, and packaged baked goods. Stock up instead on healthier things like fresh fruits, raw veggies, hummus, nuts, or popcorn.
