Food allergy or food intolerance?
Around one or two people out of every 100 in the UK have a food allergy, but food intolerance is more common.
Genuine food allergy is rare. About 2% of the population and 8% of children under the age of three are affected.
What is a food allergy?
A food allergy is a rapid and potentially serious response to a food by your immune system. It can trigger classic allergy symptoms such as a rash, wheezing and itching.
The most common food allergies among adults are to fish and shellfish and nuts, including peanuts, walnuts, hazelnuts and brazil nuts. Children often have allergies to milk and eggs as well as to peanuts, other nuts and fish.
