The Claim

Higher intake of plant protein is associated with a 23% lower risk of chronic kidney disease (RR = 0.77, 95% CI: 0.61–0.97), with a non-linear dose-response relationship indicating that consuming 30 g/day of plant protein reduces risk by 43% compared to lower intakes, based on data from six prospective cohort studies.

In plain English

People who consume more plant protein have a lower risk of developing chronic kidney disease, with those eating 30 grams per day showing a 43% lower risk compared to those eating less.

Why this might work

Eating more plant proteins like beans and tofu changes the bacteria in the gut to produce fewer harmful waste products. These harmful products normally build up and damage the kidneys over time. With fewer of them, the kidneys face less strain and stay healthier longer.

  1. Study: Association between dietary protein intake and risk of chronic kidney disease: a systematic review and meta-analysis

    People who eat more plant-based proteins like beans and tofu have a lower chance of getting kidney disease, especially when they eat about 30 grams a day — and this study found exactly that.
