Phosphorus is a vital mineral that contributes to various essential functions in the body, primarily recognized for its role in building and maintaining strong bones and teeth. It is a key component of DNA, RNA, and ATP (adenosine triphosphate), a molecule that stores and transfers energy within our cells. Phosphorus is crucial for cellular energy production, acid-base balance, and nerve function. While phosphorus deficiency is rare, maintaining a balanced intake is essential. This mineral can be found in a variety of foods, especially dairy products, meat, and whole grains. The balance of phosphorus with other minerals, like calcium, is important for overall health, as it contributes to the structural integrity of bones and helps in various metabolic processes.
