Phenylketonuria (PKU) and the Need for Good Nutrition
PKU is a genetic, metabolic disorder which prevents the body from oxidizing phenylalanine hydroxylase. As this chemical continues to build up, mental retardation, sometimes severe, may result, with very few of those with untreated PKU having an IQ over 50. It is important to have a low protein diet, which is the only way to remove the excess phenylalanine from the blood, and this diet should be started as early as possible to minimize the risk of mental retardation.
