Allergy symptoms with food
People with food allergies have an allergic reaction when they come in contact with certain foods. This happens because their immune system reacts to the proteins in that food. About twelve million people in the United States have food allergies. The most common offending foods are cow’s milk, eggs, peanuts, wheat, soy, fish, shellfish, and tree nuts.
Signs of a food allergy may include: rash or itchy skin, a stuffy, itchy nose, with sneezing, itchy and teary eyes, or swelling. It can also provoke vomiting, stomach cramps or diarrhea. In extreme cases, people can have a serious reaction called anaphylaxis, which often times will presents with the previous symptoms along with throat swelling and shortness of breath. This is a medical emergency.
