When severe, this reaction is named anaphylaxis, and can be life threatening.

Allergy or Intolerance?

Most reactions in order to food are probably not allergic inside nature, but instead intolerance.

This means of which there is no allergic antibody present against the food inside the particular person. Intolerance could be grouped as toxic plus non-toxic. Toxic reactions would be anticipated to occur in many people if plenty of of the foods was eaten, these include alcohol, caffeine or even in cases of food-poisoning.

Individuals with lactose intolerance experience bloating, cramping and diarrhea within minutes to hrs after eating lactose-containing foods, but carry out not experience some other symptoms of food allergies.

Non-allergic Immunologic Reactions

A less common form associated with non-allergic reactions to food involves the immune system, nevertheless there are zero allergic antibodies existing. This group contains celiac sprue plus FPIES (food proteins induced enteropathy syndromes).
