Histamine is a chemical that triggers allergic reactions in the body as the immune system’s way of defending the body against foreign matter. It triggers symptoms like a scratchy throat, sneezing, and itchy eyes. Most allergy medications contain antihistamines to combat the symptoms. Apart from medications, certain foods contain nutrients that act as natural antihistamines and may help ease allergies. Here are a few foods that can help combat allergies.

• Vitamin C
  Among all natural antihistamines, vitamin C is one of the most effective ones when it comes to dealing with allergy symptoms. The vitamin also boosts the immune system as foods that contain it have anti-inflammatory and antioxidant properties. Adding foods like oranges, lemon, lime, kiwi fruit, and cantaloupe melon to the diet can help relieve allergy symptoms.
• Bromelain
  Bromelain has anti-inflammatory properties and is often useful for alleviating inflammation and swelling of the sinuses due to allergies. It also helps treat respiratory distress caused by allergic reactions. Bromelain is available as a supplement, but it is also naturally present in pineapples. That said, it is recommended to have pineapples in moderation as the fruit also contains histamine.
• Probiotics
  This is another highly beneficial group of foods that act as natural antihistamines. Foods with probiotics are good for the immune system and may also help ease allergy symptoms. Probiotic foods contain healthy microbes and are good for gut health and the digestive system. Yogurt, kefir, sauerkraut, and miso are a few probiotics that can help soothe allergies like allergic rhinitis.
• Quercetin
  Quercetin is an antioxidant flavonoid that is commonly found in apples and onions. This natural antihistamine can alleviate respiratory distress that may occur due to allergic reactions. Dietary sources of this enzyme also include honey, raspberries, red grapes, cherries, green leafy vegetables, and citrus fruits. Quercetin is also available in the form of supplements.
• Omega-3 fatty acids
  Omega-3 fatty acids also work as natural antihistamines. Foods rich in these healthy fats are beneficial for heart health and boost immunity, and their anti-inflammatory properties help ease allergies. Fatty fish like salmon, tuna, and mackerel and walnuts and chia seeds are excellent sources of omega-3 fats.
