The Claim

Higher protein intake does not increase the risk of chronic kidney disease in healthy adults during short-term observation periods, despite inducing physiological changes in glomerular filtration rate, calcium excretion, and urea levels.

Description
1 study reviewed
In plain English

In healthy adults, eating more protein for a short time does not lead to chronic kidney disease, even though it temporarily changes kidney function markers like filtration rate and urea levels.

See the scientific wording

There is no convincing evidence that higher protein intake increases the risk of chronic kidney disease in healthy adults over short-term observation periods, despite physiological changes in GFR, calcium excretion, and urea levels.

Why this might work

When more protein is eaten, the kidneys filter more blood, release more calcium in urine, and produce more urea to handle the extra nitrogen, but these changes are normal adjustments that keep the kidneys healthy and do not cause harm.

    Eating more protein makes your kidneys work a bit harder and changes some urine and blood markers, but it doesn't hurt your kidneys or cause disease in healthy people over two years or less.
