The Claim

Excessive protein intake, defined as greater than 1.5 grams per kilogram per day or more than 25% of total energy intake, is associated with glomerular hyperfiltration, increased oxidative stress, inflammation, and accelerated decline in kidney function in individuals with chronic kidney disease or predisposition to chronic kidney disease, based on observational studies in humans and experimental models.

In plain English

Eating too much protein might make kidney problems worse in people who already have kidney issues or are at risk for them, by putting extra strain on the kidneys and causing more damage over time.

See the scientific wording

Excessive protein intake (>1.5 g/kg/day or >25% of total energy) in individuals with chronic kidney disease (CKD) or predisposition to CKD is associated with glomerular hyperfiltration, increased oxidative stress, inflammation, and accelerated decline in kidney function, based on observational studies in humans and experimental models.

What the research says

1 study
  1. Study: Low‐protein diet for chronic kidney disease: Evidence, controversies, and practical guidelines

    The study looks at how too much protein can harm people with kidney problems, and it agrees with the claim that it causes stress, swelling, and faster kidney damage.
