Exploring the Facts:
In Healthy Individuals
For people with healthy kidneys, there is no strong evidence that a high-protein diet causes kidney damage. The kidneys are capable of processing increased protein intake without harm in the absence of underlying kidney disease.
In Individuals with Preexisting Kidney Issues
For those with chronic kidney disease (CKD) or reduced kidney function, consuming excessive protein can:
- Increase the workload on the kidneys.
- Accelerate the progression of kidney damage.
Such individuals are often advised to follow a low- to moderate-protein diet under medical supervision.
Why the Concern Exists
High protein intake increases the production of metabolic waste products like urea, which the kidneys must filter. This leads to:
- Increased glomerular filtration rate (GFR) (a measure of kidney workload).
- Higher urine output, which might be mistaken as a strain on the kidneys but isn’t harmful for healthy kidneys.
Bottom Line
If your kidneys are healthy:
- A high-protein diet is unlikely to harm them.
- Balance protein intake with other macronutrients and stay hydrated.
If you have any concerns about kidney health or existing conditions, consult a healthcare professional or dietitian before significantly altering your diet.
