Food Allergy vs. Food Intolerance

Learn the difference between a food allergy and a food intolerance from gastroenterologist Lisa Ganjhu, M.D. in this Howcast stomach problems video.


So, a lot of times, people get confused between food allergies and food intolerances, but they're two very different entities. A food allergy, is a clear allergy. That means, if we take some food that we are allergic to, we can get anaphylaxis or hives or we can have our throat closing up, that's a true allergy.

Now food intolerances, just mean that we don't tolerate the food, so we have more of a digestive system reaction. So, we may have some nausea, we may have some pain, may have some indigestion when we consume those foods, but we don't actually have a real allergic reaction, where we need to worry about a life threatening reaction.
