PKU Diet

The PKU (Phenylketonuria) diet is a specialized nutrition plan for individuals with PKU, a genetic disorder that impairs the body’s ability to process the amino acid phenylalanine. Elevated levels of phenylalanine can cause brain damage if untreated. The diet limits high-phenylalanine foods like meat, dairy, nuts, and certain grains. Instead, it emphasizes specially formulated low-protein foods, fruits, vegetables, and medical formulas that provide essential nutrients without excess phenylalanine. Regular blood monitoring ensures levels stay safe, helping those with PKU maintain health and prevent complications while allowing for a balanced, enjoyable diet.
