A child with PKU can safely consume which of the following?

The correct choice, which includes carrots and celery sticks, reflects the dietary needs of a child with phenylketonuria (PKU). PKU is a metabolic disorder characterized by an intolerance to phenylalanine, an amino acid found in protein-rich foods. In this context, low-protein foods like vegetables, including carrots and celery sticks, are safe and beneficial for individuals with PKU. These foods provide essential nutrients without posing the risk of elevated phenylalanine levels in the body.

In contrast, foods such as potatoes, milk, and peanut butter are higher in protein and contain significant amounts of phenylalanine. For example, milk is a rich source of protein and thus is unsafe for someone with PKU. Similarly, potatoes, despite being a starchy vegetable, still contain more protein than other vegetables like carrots and celery, making them less suitable. Peanut butter is very protein-rich and would similarly be a source of phenylalanine, making it inappropriate for a child with PKU. Understanding the specific nutritional needs of a child with PKU is crucial for managing their diet effectively.
