What does it mean to have food intolerance?
Many people think they have a food allergy, but in fact they have food intolerance. An intolerance can cause some of the same symptoms as a mild food allergy, like an upset stomach. It can make you feel bad, but it isn't dangerous.
Food intolerances are much more common than food allergies. True food allergies are a reaction to food or food additives by your body's immune system. But a food intolerance doesn't cause an allergic reaction.
