14 Foods That Fight Seasonal Allergies
11. Pumpkin Seeds

Pumpkin seeds are rich in magnesium, zinc, and antioxidants, all of which support immune balance. Magnesium acts as a natural bronchodilator, helping open airways and ease breathing, while zinc helps regulate immune cell function. A 2010 study in Clinical and Experimental Allergy linked magnesium deficiency to increased bronchial reactivity. Add a handful of roasted pumpkin seeds to your daily routine to ease inflammation and keep allergy symptoms at bay.
12. Blueberries

Blueberries are packed with anthocyanins—natural antioxidants that reduce inflammation and strengthen the lining of blood vessels and airways. A 2013 study in Advances in Nutrition noted that anthocyanins may help protect against oxidative stress caused by allergens. Their high vitamin C content also supports the immune system. Enjoy a cup of fresh or frozen blueberries daily to soothe allergic flare-ups and support overall respiratory health.
