Food allergies are caused by a lapse in your immune system where it mistakenly identifies food proteins as threats. This can cause the food you eat and are allergic to to make you sick instead of nourishing your body. Your immune system will then attack those proteins and release histamines and other chemicals that can cause a variety of symptoms which can cause discomfort, or even be life threatening.
Food allergies and food intolerances are commonly confused, and are not the same thing. Food intolerances may cause some discomfort, but they do not trigger the immune system and thus will not result in anaphylaxis.
