Will Protein Damage My Kidneys?

Short answer – NO!

Some doctors state that patients with kidney disease should not consume “excess” protein.

But there’s a big difference between a patient and an otherwise healthy individual with normal functioning kidneys!

There are others who’ll say that your kidneys have to work “extra hard” to metabolize the “excess” protein.

DUH! That’s their job!

By that logic, people should stop exercising because the heart has to work “extra hard” while you’re working out!

Enough with these bogus theories.

Let’s examine the research.

Studies done on healthy individuals and athletes have not shown any adverse effects on kidney function from a high protein diet.

“While protein restriction may be appropriate for treatment of existing kidney disease, we find no significant evidence for a detrimental effect of high protein intakes on kidney function in healthy persons after centuries of a high protein Western diet.”

“In healthy obese individuals, a low-carbohydrate high-protein weight-loss diet over 2 years was not associated with noticeably harmful effects on GFR, albuminuria, or fluid and electrolyte balance compared with a low-fat diet.”

“It appears that protein intake under 2.8 g/kg does not impair renal function in well-trained athletes as indicated by the measures of renal function used in this study.”

“In resistance-trained young men who do not significantly alter their training regimen, consuming a high protein diet (2.6 to 3.3 g/kg/day) over a 4-month period has no effect on blood lipids or markers of renal and hepatic function.”
