Question
What is the best treatment method for phenylketonuria?
Answer
Phenylketonuria is a congenital metabolic disease that is typically treated through dietary control. Before a child reaches one year old, low-phenylalanine formula should be used. After that, the diet should primarily consist of starches, vegetables, and fruits, with protein intake restricted. This dietary approach should be maintained until adolescence is fully developed. Early treatment is more effective.
