What is meant by the term 'food allergy'?

The term 'food allergy' specifically refers to an immune system reaction that occurs soon after eating a certain food. This reaction happens because the immune system misidentifies a harmless food protein as a threat, which can lead to a range of symptoms, from mild hives or digestive discomfort to severe anaphylaxis. This immediate response distinguishes food allergies from other food-related issues, such as intolerances, which do not involve the immune system. Understanding food allergies is crucial in managing dietary restrictions and helping individuals avoid potentially life-threatening reactions.
