English to French Medical Nutrition food intolerances

J'ai rencontré ce terme dans un texte expliquant l'intolérance au lactose (source américaine), mais je ne trouve pas d'équivalent français. Comment le traduiriez-vous ?

Voici le paragraphe dont il est extrait :
Overall, about 75 percent of the world's population, including 25 percent of those in the U.S., lose their lactase enzymes after weaning.7 The recognition of this fact has resulted in an important change in terminology: those who could not digest milk were once called "lactose intolerant" or "lactase deficient." They are now regarded as normal, while those adults who retain the enzymes allowing them to digest milk are called "lactase persistent."
