Food Allergies vs. Intolerance
Reviewed by Curt Chaffin, MD
Hives, swelling of the tongue, breathing issues…What does this mean? These are common symptoms of food allergies that people often get confused with food intolerance or food sensitivity. The good news is that there are ways to determine if you have a food allergy or if you may still be able to eat the foods you love without side effects. Either way, we can help.
What Is the Difference Between Food Intolerance and Food Allergies?
Food allergies occur when the immune system targets an allergen as a threat, triggering an allergic reaction. Food intolerance, on the other hand, is when the body struggles to digest certain foods and affects the digestive system—not the immune system. Food intolerances generally lead to an upset stomach and are usually non-life-threatening, while food allergies can be severe.
