Garlic and onions
Aside from fighting off vampires and making your breath smell like a garbage can, garlic is actually pretty damn good for you. It's been a natural remedy for centuries, and modern studies have shown that garlic's antioxidant properties can help fight inflammatory diseases, such as metabolic syndrome and cardiovascular disorders. Onions are in the same realm; they contain similar antioxidants as garlic, and also polyphenols to fight inflammation.
Vitamin D is something you need but are probably deficient in, what with skin cancer fears and all. It's good for the immune system, can help stave off Type 2 diabetes, and is a proven anti-inflammatory. Luckily, you don't need to become tanorexic to reap the sunshine vitamin's benefits; fatty fish such as salmon, trout, and albacore tuna contain healthy doses. They're also packed with anti-inflammatory Omega-3 fatty acids, so opting for surf over turf is a double-whammy against inflammation.
