Three pathological conditions, which appear to be increasing in
frequency, are related to gluten ingestion: i) food allergy, which
affects 0.2%e0.5% of the population but has major clinical implications;
ii) coeliac disease, which is an autoimmune disorder
caused by the ingestion of gluten (between 0.1% and >1.6%); and iii)
gluten sensitivity, a recently rediscovered condition due to gluten
intolerance.
