Potentially, any food could cause an allergy. However, the most severe food allergies are commonly caused by just a few foods: namely, milk, eggs, fish, crustaceans, peanuts, soybeans, tree nuts, and wheat.
Alerģiju var izraisīt praktiski jebkurš pārtikas produkts, taču vissmagāko alerģisko reakciju izraisa tikai daži produkti: piens, olas, zivis, vēžveidīgie, rieksti, īpaši zemesrieksti, soja un kvieši.
