Excessive protein intake may result in increased excretion of which mineral?

Excessive protein intake is associated with increased excretion of calcium in the urine. This is primarily due to the fact that a high-protein diet can lead to a more acidic environment in the body, which may increase the need for calcium to neutralize the acid. As the body releases calcium from the bones to maintain a proper acid-base balance, this results in higher levels of calcium being excreted through urine.

Moreover, protein-rich foods often come from animal sources, which can be higher in sulfur-containing amino acids. The metabolism of these amino acids can further increase calcium loss through renal excretion. Therefore, individuals consuming high amounts of protein, especially if not balanced with adequate calcium intake, may risk depletion of calcium stores in their body, leading to potential health issues over time, such as osteoporosis.

This understanding emphasizes the importance of a balanced diet that considers adequate protein intake along with sufficient minerals to promote overall health and prevent imbalances.
