What is food allergy?
Some people react with what doctors call a hypersensitivity reaction when eating certain foods or additives. Typically it is commonly used foods that cause the reactions.
For an adverse reaction to be called a food hypersensitivity, the symptoms of an individual must be of a certain kind, specifically:
- Appear when a person eats the problem food
- Disappear or diminish when a person avoids the problem food, and
- Reappear when the person reintroduces the problem food.
Food hypersensitivity is divided into two types, food allergy and non-allergic food hypersensitivity. See the subpages for more information.
