Food allergies and food intolerances are often confused, but they are different. An allergy involves the immune system, while an intolerance usually affects digestion and causes discomfort rather than danger.
Allergic reactions can include hives, swelling, vomiting or wheezing, and often start within minutes of eating. Intolerance symptoms, such as bloating, gas or cramps, usually build more slowly and may depend on how much you eat. Trouble breathing, throat swelling or fainting after eating is an emergency, so get emergency help right away.
- Keep a simple diary of what you eat and any symptoms.
- Read ingredient labels every time, because recipes can change.
- Tell restaurant staff about an allergy whenever you eat out.
If you think a food is causing your symptoms, talk to a doctor about testing rather than cutting foods out on your own.
