What Are Food Allergies?
Food allergies occur when your immune system mistakenly identifies a food protein as harmful. This triggers a cascade of reactions designed to “fight off” the perceived threat. It’s different from a food intolerance, which doesn’t involve the immune system and typically causes less severe symptoms. Common food allergens – often referred to as the “Big 9” – account for 90% of allergic reactions.
