[Risk factors of food allergy].
Food allergy or allergic food hypersensitivity is defined as an adverse immunologic reaction caused by immunologic mechanisms mediated or not by IgE. It is a complex disease influenced by polygenetic heritance and environmental factors. Many risk factors have been investigated, pre natal and post natal, and variable and controversial results have been obtained. The most important risk factors associated with food allergy are atopy, lack of breast feeding at least three to six months and early weaning (before four-six months).
