What’s the Difference Between a Food Allergy and Intolerance
Food can be comforting and delicious. Food can bring together friends and family for a warm, fun-filled experience. So true, unless you or a loved one experiences a food allergy or intolerance. While both can lead to adverse reactions that can leave you feeling miserable, a food allergy can be life-threatening in some cases. Our board-certified food allergist and team at Safe2Bite | Texas Food Allergy Center offer personalized food allergy testing, treatment, and management to help you live safely and confidently.
The question is, do you have a true allergy, or are your symptoms the result of food intolerance?
Food Allergy Symptoms and Reactions
A food allergy is an immune system response that occurs after consuming certain foods, such as peanuts, milk, eggs, seeds, tree nuts and shellfish. It develops as a result of the body mistakenly identifying proteins in these foods as harmful, leading to adverse symptoms.
Food allergy symptoms can range from mild to life-threatening. Common symptoms include those listed below.
- Hives, welts, rashes or itchy skin.
- An itchy or tingly feeling in the mouth, throat or ears.
- Stomach pain, vomiting and diarrhea.
- Having trouble breathing, wheezing or a cough that persists.
- Swelling of the tongue or throat that makes it hard to breathe.
- Feeling faint, tired, lethargic or dizzy.
- A fast heartbeat or losing consciousness.
When it comes to severe allergies, consuming even the tiniest amounts of an allergen can cause a potentially life-threatening reaction known as anaphylaxis. If you have a known food allergy, it’s important to keep an epinephrine auto-injector with you at all times, which can be life-saving in the event of accidental exposure.
What Is Food Intolerance?
Unlike food allergies, which involve an immune system response, a food intolerance results from the digestive system’s inability to properly process a food or one of its components, often due to an enzyme deficiency, as with lactose intolerance, or to sensitivity to a natural chemical. Intolerance symptoms are generally confined to the gut and are dose-dependent, meaning the more of a food you consume, the worse you feel. While often miserable, food intolerances are not life-threatening.
Food intolerance can also cause a range of uncomfortable symptoms. You may experience one or more of the following.
- Stomach cramps, bloating or gas.
- Diarrhea or constipation.
- Nausea and occasionally vomiting.
- Headaches or migraines.
- Chronic fatigue or feeling tired after meals.
- Skin rashes, hives or flushing.
- Heartburn or acid reflux.
- A runny nose or congestion.
