The Claim

Dietary casein causes metabolic acidosis and a progressive decline in glomerular filtration rate (GFR) in rats with remnant kidneys, mediated through endothelin A receptors.

Source: Dietary protein causes a decline in the glomerular filtration rate of the remnant kidney mediated by metabolic acidosis and endothelin receptors.

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.

In plain English

Eating a protein called casein makes rats with damaged kidneys sicker by making their blood too acidic and slowly worsening their kidney function, and this happens because of a specific part in their body called endothelin A receptors.

What the research says

1 study

  1. Study: Dietary protein causes a decline in the glomerular filtration rate of the remnant kidney mediated by metabolic acidosis and endothelin receptors.

    The study shows that feeding casein to rats with kidney problems causes acid buildup and worsens kidney function through a specific receptor, exactly as the claim says.
