Symptoms of food intolerance can include nausea, gas, cramps, abdominal pain, diarrhea, irritability, nervousness, or headaches.</p> <p>A food allergy happens when the body's immune system, which normally fights infections, sees the food as an invader. This leads to an allergic reaction &mdash; a response from the immune system in which chemicals like histamine are released in the body. The reaction can cause symptoms like breathing problems, throat tightness, hoarseness, coughing, vomiting, abdominal pain, <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/hives.html/">hives</a>, swelling, or a drop in blood pressure.</p> <p>Even if previous reactions have been mild, someone with a food allergy is always at risk of the next reaction being life-threatening. Eating a microscopic amount of the food, or sometimes even touching or inhaling it, could lead to anaphylaxis. So anyone with a food allergy must avoid the problem food(s) entirely and always carry emergency injectable epinephrine.</p> <p>Many people with food sensitivities, on the other hand, can ingest a small amount of the bothersome food without a problem.</p> ¿En qué se diferencia una alergia alimentaria de una intolerancia alimentaria?Las intolerancias alimentarias pueden hacer que una persona se encuentre mal.
