Question
Newborn screening reveals a child has phenylketonuria (PKU), and parents inquire about dietary control and milk selection for the patient.
Answer
Patients with phenylketonuria need to strictly control their intake of phenylalanine, and should use low phenylalanine formula milk and specially formulated foods. These products are usually more expensive and sometimes need to be imported from abroad. Patients still need to continue consuming specially formulated foods throughout their growth process. Early newborn screening and appropriate dietary control as prescribed by the doctor can help prevent intellectual development from being affected. Additionally, a balanced intake of fruits and vegetables is also important.
