                                For individuals with phenylketonuria (PKU), a rare genetic disorder affecting how the body processes the amino acid phenylalanine (Phe), protein intake must be meticulously controlled throughout life.  The specific amount of protein a person with PKU can eat depends on their individual tolerance, which is managed through a low-phenylalanine diet and special medical formulas.
