What is a key dietary consideration for a child with phenylketonuria (PKU)?

  • A. High-fiber diet
  • B. Low-phenylalanine diet
  • C. Increased dairy intake
  • D. High-sodium diet
Correct Answer: B

Rationale: A low-phenylalanine diet is crucial for managing PKU to prevent neurological damage and maintain normal development. Phenylalanine is an amino acid found in protein-containing foods, and individuals with PKU have difficulty metabolizing it. Consuming foods low in phenylalanine helps prevent the buildup of toxic byproducts in the body. Choices A, C, and D are incorrect. A high-fiber diet, increased dairy intake, and high-sodium diet are not specific dietary considerations for PKU management. In fact, dairy products are a source of protein and phenylalanine, which should be limited in PKU.
