The Claim
Non-linear dose-response relationships exist between plant protein intake and chronic kidney disease risk, with the greatest risk reduction observed at intakes of 30–45 grams per day and diminishing returns beyond this range, as determined by dose-response analysis from six prospective cohort studies.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Consuming 30 to 45 grams of plant protein per day is associated with the lowest risk of chronic kidney disease. Eating more than this amount does not further reduce risk.
See the scientific wording
The association between plant protein intake and reduced chronic kidney disease risk is non-linear, with the greatest benefit observed at intakes of 30–45 grams per day, beyond which additional intake provides diminishing returns, based on dose-response analysis from six prospective cohort studies.
Eating 30–45 grams of plant protein daily feeds beneficial gut bacteria, which produce fewer harmful waste products that damage the kidneys. This lowers inflammation and reduces the workload on kidney filters, preventing long-term damage. Eating more than this amount doesn’t add extra protection.
What the research says
1 studyEating 30 to 45 grams of plant protein a day helps protect your kidneys the most, and eating more than that doesn’t help much more — and this study found exactly that.
