Question

Which action can prevent the mental retardation that otherwise results from PKU (phenylketonuria)?​

Quizplus · Accepted Answer

Keeping one ingredient, phenylalanine, out of the child's diet is the only action that can prevent mental retardation in PKU. This is because children with PKU lack the ability to break down phenylalanine, which can build up in their bloodstream and cause damage to their developing brain. The other options listed do not directly address the problem of phenylalanine accumulation in the body.
