Food allergy is a condition in which certain foods trigger an abnormal immune response. It happens when our immune system perceives certain foods as harmful, and our body mounts a series of defense mechanisms, including releasing chemicals, such as histamine, that cause inflammation.
For people with food allergies, even exposure to a small amount of a problem food can trigger an allergic reaction. สมัครสมาชิก UFABET วันนี้ รับเครดิตฟรีทุกวัน Food allergy symptoms can occur as soon as a few minutes after exposure to as long as 2-3 hours or 2-3 days later.
