You are what you eat. At least, that's the old adage. It's also one I believe in — what you put into your body has a big effect on how you feel. There are foods that fight fat and detox foods. There are even foods that help you sleep better and look fresher. Adding to the list of foods that fuel with a purpose are foods that help ease pain. Whether it's a headache, post-workout soreness, or an injury, these foods will help ease the pain away in a totally natural way.
