How can excessive protein intake affect the kidneys?

Excessive protein intake can lead to increased workload and potential damage to the kidneys over time because the kidneys are responsible for filtering the byproducts of protein metabolism, primarily urea, from the blood. When protein consumption is excessively high, the kidneys must work harder to process and eliminate these waste products. This increased workload can put stress on kidney function and may lead to complications, particularly in individuals with pre-existing kidney conditions. Over time, this strain can contribute to diminished kidney function and an increased risk of kidney disease.

The correct response highlights the need for moderation in protein intake to maintain kidney health, especially for those at risk for renal issues. Understanding this relationship is crucial in nutritional planning and for individuals monitoring their kidney health.
