Gluten free grains are sometimes used in the management of which metabolic condition due to protein restrictions?

• A. PKU
• B. Celiac disease
• C. Lactose intolerance
• D. Asthma

Answer: (A)

The key idea here is managing phenylalanine intake. Phenylketonuria (PKU) requires lifelong restriction of phenylalanine, an amino acid found in most protein-containing foods. Choosing gluten-free grains provides carbohydrate calories without contributing as much phenylalanine as many high-protein grains, helping keep blood phenylalanine levels within safe limits while still offering variety and energy in the diet. This makes gluten-free grains a useful option in PKU management. The other conditions involve different dietary issues: celiac disease is treated by avoiding gluten to prevent intestinal damage, lactose intolerance by avoiding lactose, and asthma is not driven by a protein-restriction diet.
