Allergist Brent T. Griffin, MD: A food allergy is a potentially dangerous reaction to a food. A food sensitivity is signs and symptoms caused by eating the food that aren’t necessarily dangerous. They can be very uncomfortable.
A food allergy is an immune response where your body reacts to a food. Again, it can give you very serious symptoms, such as shortness of breath, wheezing, loss and loss of consciousness. These kind of things, a food intolerance or sensitivity, is generally not life-threatening and not as serious.
There’s a lot of overlap in symptoms between a food allergy and a food sensitivity, and this is something that you really should see an allergist to sort out.
