Food intolerance is an adverse reaction to a chemical in a food or drink. It differs from a food allergy in that no immune response is involved.
Common symptoms of food intolerance include:
Asthma symptoms can also be triggered in some people.
The severity of an adverse reaction is linked to the amount of the culprit food consumed, the more a person consumes, the more severe the reaction will be. It is common for patients with food intolerance to react to several chemicals that are found in a wide range of foods. A family history of symptoms and specific chemical intolerances is common.
It can be difficult to determine whether a person has an allergy or intolerance to certain foods so it is important to see your doctor for a diagnosis.
