Onions, garlic, leeks, shallots, scallions and chives offer multiple anti-inflammatory benefits. Onions, for instance, are a rich source of the anti-inflammatory vitamin C and quercetin, which help relieve allergy symptoms. Onions also contain onionin A, a molecule that targets the immune system to prevent unwanted inflammation. Garlic contains a range of sulfurous compounds that reduce inflammation throughout the body and has antiviral and antibacterial properties. Research shows that the flavonoid antioxidants, organosulfur compounds, and vitamin C found in leeks reduces inflammation and protects cells from oxidative damage.
