Which of the following foods is high in phosphorus?

Dairy
Apples
Carrots
Rice

The correct answer is: Dairy

Dairy products are well-known for being high in phosphorus, which is an essential mineral important for several bodily functions, including bone health and energy production. Foods that are rich in protein, such as dairy, meats, and nuts, typically contain higher levels of phosphorus compared to many fruits and vegetables. In contrast, apples, carrots, and rice contain relatively low levels of phosphorus. This distinction is crucial, especially for patients undergoing dialysis, as managing phosphorus intake can significantly impact their health and treatment outcomes. High phosphorus levels can lead to complications such as weakened bones and cardiovascular issues, making it important for dialysis patients to monitor their phosphorus consumption. Thus, recognizing dairy as a high-phosphorus food is essential for dietary planning in the context of kidney health.
