Research Statement

Our research group has conducted studies in individuals with phenylketonuria (PKU) that establishes the acceptability and safety of foods made with the whey protein, glycomacropeptide, in the nutritional management PKU. PKU is a genetic disorder caused by deficiency of the hepatic enzyme phenylalanine hydroxylase that converts the essential amino acid phenylalanine to tyrosine. The Waisman Biochemical Genetics Clinics follows over 160 clients with PKU. To prevent brain damage and cognitive impairment those with PKU must follow a lifelong, low-phenylalanine diet that is restricted in natural foods and requires ingestion of a bitter tasting amino acid formula. Glycomacropeptide is uniquely suited to the PKU diet because it is the only known dietary proteins that contains only trace amounts of phenylalanine. Low-phenylalanine food products made from GMP provide a palatable and acceptable alternative to the amino acid formulas currently required in the PKU diet.

Our GMP research was featured on Wisconsin Public Television. This show can be viewed at .
