PKU Diet Explained: Lifelong Treatment for Phenylketonuria

Sinofn Health has issued information detailing phenylketonuria (PKU), a rare genetic disorder affecting approximately 1 in 11,000 births in China. The condition requires lifelong management through a highly restrictive diet to prevent the toxic buildup of phenylalanine (Phe), which can cause intellectual disabilities and irreversible nerve damage.

The PKU diet necessitates the strict avoidance of protein-rich foods such as meat, eggs, dairy products, nuts, and legumes. Patients rely on low-Phe fruits and vegetables, specially formulated PKU foods like bread and pasta, and medical formulas that provide essential nutrients without phenylalanine.

Early intervention is crucial, with treatment ideally starting immediately after birth to ensure normal cognitive development. Delays in treatment beyond three months can lead to irreversible cognitive impairment. Sinofn Health highlights the critical nature of adhering to these dietary restrictions as the primary method of managing PKU throughout an individual's life.
