PKU is short for "phenylketonuria." People with PKU can't process one of the amino acids found in many foods. The amino acid, called phenylalanine or "Phe" for short, builds up in the body.

Too much Phe is toxic to the brain and can cause many problems. In infants and children, if PKU is not treated, the resulting high Phe can cause severe mental retardation. Even if PKU is treated problems like brain changes, lower IQ, and behavior problems may still occur.

The @PKU app will help people with phenylketonuria to determine how much phenylalanine is in the foods they eat - anytime - anywhere!
