[Modern nutrition and development of new allergies].
The prevalence of food allergy varies between 1 and 8% and depends on age, countries, symptoms and allergens. Main food allergens remain peanut, nuts, egg, cow milk, wheat, soybeans and fish. However, novel food industrial processes have induced new food allergies. Some are related to unusual components, like lupine seeds or flour or to modified food, like wheat or soybean isolates. Other unexpected allergies are due to residues of strong allergens--like peanut or egg--which are present in very small amounts in processed food. Swiss and european legislation have edicted lists of allergenic foods which have to be specified to the consumers. However, the legislation remains still incomplete and labelling of novel food components or modified allergens as well as as trace allergens is still far from being exhautive.
