Quizplus · Accepted Answer

PKU disease occurs when there is a deficiency of the phenylalanine hydroxylase enzyme. Untreated, it leads to cognitive delays and other health problems. These children must avoid foods with phenylalanine. Phenylalanine is part of protein; therefore, protein intake from any source must be limited. Vitamins are not protein.
