14 Foods That Fight Seasonal Allergies
9. Garlic

Garlic is a natural immune modulator with antiviral, anti-inflammatory, and antihistamine properties. It contains allicin, a compound that helps suppress the activity of enzymes that generate inflammatory prostaglandins and histamines. According to a study published in The Journal of Immunology Research, garlic extract helped reduce allergic airway inflammation in mice. Include raw or lightly cooked garlic in your meals to enhance immune response and reduce seasonal sniffles.
10. Green Tea

Green tea contains the antioxidant EGCG (epigallocatechin gallate), which has been found to block histamine release and suppress inflammation at the cellular level. A 2002 study from Kyoto University found that EGCG significantly reduced allergic reactions in lab settings. Drinking green tea regularly can help lower the body’s reactivity to allergens, making it a calming beverage choice during allergy season. Bonus—it also supports detoxification and hydration.
