Food Allergy Definition – Key Facts Food allergies are a significant health concern in the United States, affecting millions of people. But what exactly is a food allergy? In this section, we will explore the definition of food allergies and provide key facts to help you better understand this condition.
A food allergy is an adverse immune response to specific proteins found in certain foods. When someone with a food allergy consumes or comes into contact with an allergenic food, their immune system mistakenly identifies the proteins as harmful substances and triggers a defensive reaction.
This immune response can vary in severity from mild symptoms like itching or hives to more severe reactions such as difficulty breathing or anaphylaxis, a life-threatening condition. The most common food allergens include peanuts, tree nuts, shellfish, fish, dairy, eggs, soy, and wheat.
It’s essential to differentiate food allergies from other food-related conditions, such as food intolerances or sensitivities. Unlike food allergies, which involve the immune system, intolerances or sensitivities typically involve the digestive system and are not life-threatening.
Understanding the definition of food allergies is the first step in raising awareness and promoting safety for those affected. Let’s dive deeper into the impact of food allergies, the symptoms, and the ways these allergies can be diagnosed and managed.
Understanding Food Allergies
