has been sensitized to it
Antigen - ANSWER any molecule that will elicit an immune response in the body
Allergen - ANSWER when an antibody elicits a hypersensitivity reaction as in allergy
Food sensitivity - ANSWER unclear whether the reaction is immunologically related or due to a biochemical
or physiologic defect
Food intolerance - ANSWER adverse reaction to a food or food additive that does not involve the immune
system and results from the body's inability to digest, absorb, or metabolize a food or component of the
food
Atopy - ANSWER condition of genetic predisposition to produce IgE antibodies in response to an allergen
and to develop typical symptoms
Dysbiosis - ANSWER imbalance in the microbiota which can impair digestion and affect overall health
Immunoglobulins (Ig) - ANSWER antibodies contain a globulin protein
Lymphocytes - ANSWER command and control cells of the immune system and contain B-cells and T-cells
B-cells - ANSWER arising from stem cells in the bone marrow

of the GI microbiota thus conferring benefits upon host health
Adverse reaction to food (ARF) - ANSWER any undesired response to a food regardless of mechanism
Food allergy (hypersensitivity) - ANSWER immune-mediated reaction to a normally harmless food protein
or happen that the body has erroneously identified as harmful; food reaction that occurs consistently after
ingestion, inhalation, and/or touch of a particular food, causing functional changes in target organs
IgE (immune) - ANSWER food allergies are often _______ mediated
Food intolerance - ANSWER not immune mediated; adverse reaction to a food caused by toxic,
pharmacologic, metabolic, digestive, psychological, idiosyncratic non-IgE reactions to the food or chemical
substances in food
food sensitivity - ANSWER used to describe adverse reactions to food when it is not clear whether it is
intolerance or allergy
