The Claim
High-protein intake is associated with increased glomerular filtration rate in healthy individuals, but there is insufficient evidence to conclude it causes kidney damage in those without pre-existing renal dysfunction; however, it may worsen kidney function in patients with chronic kidney disease.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating lots of protein makes your kidneys work harder in healthy people, but it probably doesn't harm them if your kidneys are already healthy. However, if you have kidney problems, high protein might make them worse.
See the scientific wording
High-protein intake is associated with increased glomerular filtration rate (GFR) in healthy individuals, but there is little evidence it causes kidney damage in those without pre-existing renal dysfunction, though it may worsen function in chronic kidney disease patients.
What the research says
1 studyStudy: Controversies surrounding high-protein diet intake: satiating effect and kidney and bone health.
The study says high-protein diets aren't proven to harm healthy kidneys, but they can make existing kidney problems worse, which matches the claim.
