What is the Difference Between a Food Allergy and Food Intolerance?

Food allergies trigger immune system responses, while food intolerances involve digestive difficulties without immune involvement. Food allergies can cause severe reactions like anaphylaxis within minutes of exposure, affecting up to 8% of children and 4% of adults. Common allergens include peanuts, shellfish, and eggs. Food intolerances, such as lactose intolerance affecting 65% of adults worldwide, typically cause digestive symptoms like bloating, gas, or diarrhea hours after eating. Intolerances are generally less dangerous but can significantly impact quality of life. Understanding this distinction helps you identify triggers and seek appropriate medical evaluation for proper diagnosis and management strategies.
