Explaining food allergies
A food allergy is a reaction of the body’s immune system to something in a food or an ingredient in a food - usually a protein.
Common symptoms include skin irritations such as rashes, hives, and eczema, and gastrointestinal symptoms such as nausea, diarrhea, and vomiting, sneezing, runny nose, and shortness of breath.
