6 Causes of Allergies
Foods
Foods are a common cause of allergies. When you consume some specific products, they would trigger abnormal immune responses in the body. More specifically, the immune system can wrongly recognize several proteins in these foods as harmful. As a result, it will activate some protective measures like producing histamine, a chemical that can trigger inflammation. In people with a food allergy, even eating a very small amount could lead to an allergic reaction. Some common foods that can trigger allergies include fish, tree nuts, peanuts, wheat, eggs, soy, shellfish, and cow’s milk. [5]
