Whey protein causes kidney damage
evidence
The Claim
Many people believe that consuming whey protein can lead to kidney damage, particularly among those who consume it in large quantities. This myth often stems from the idea that high protein intake increases the workload on the kidneys, potentially leading to damage over time.
Origin
This myth likely originated from early studies on individuals with pre-existing kidney issues, as well as a generalization from the effects of high-protein diets in animal studies.
What Science Says
Research indicates that for individuals with healthy kidneys, high protein intake does not cause kidney damage. A meta-analysis of randomized controlled trials (RCTs) has shown that protein intake, including from supplements like whey, does not adversely affect kidney function in healthy adults. However, those with pre-existing kidney conditions should consult with healthcare providers.
Verdict
Mostly False
