Os OGMs podem causar alergias?

Nesta revisão, os autores detalham as várias etapas no desenvolvimento de um transgênico que levam em consideração o seu potencial alergênico.

Além disso, realizam uma revisão sistemática dos trabalhos sobre o tema. Os dados mostram que as safras geneticamente modificadas (GM) não são mais alergênicas do que as não modificadas. Além disso, não foram encontradas evidências de que indivíduos que não são alérgicos aos alimentos convencionais desenvolvam alergia ou tenham um aumento no risco em desenvolver alergia pelo consumo de culturas GM.
