The Claim
Higher protein intake (above 0.8 g/kg body weight/day) does not increase urinary albumin excretion in healthy adults, despite physiological increases in glomerular filtration rate and calcium excretion.
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.
In healthy adults, consuming more than 0.8 grams of protein per kilogram of body weight per day does not lead to increased urinary albumin excretion, even though glomerular filtration rate and calcium excretion rise.
See the scientific wording
Higher protein intake (above 0.8 g/kg body weight/day) does not increase urinary albumin excretion in healthy adults, suggesting no short-term evidence of glomerular damage, despite physiological increases in GFR and calcium excretion.
When more protein is eaten, the kidneys filter more blood to handle the extra nitrogen waste, which increases pressure inside the filtering units. This higher pressure also causes more calcium to be lost in urine and changes the urine's acidity, but the filtering barrier itself stays intact and does not let protein leak into the urine.
What the research says
1 studyEating more protein makes your kidneys work harder and flush out more calcium, but it doesn’t make protein leak into your urine — meaning your kidneys are fine, even if they’re filtering more blood.
