One for all, High Protein Diets is not bad for your kidneys
High Protein Diets and their Effects on Kidney Function
Int. Jrnl of Sport Nutr & Ex Metabolism
In the article titled Do Regular High Protein Diets Have Potential Health Risks on Kidney Function in Athletes, the authors note that protein and amino acid intake have been recognized as hazardous potential implications for kidney function, leading to progressive impairment of this organ.
It has been suggested in literature, without clear evidence, that high protein intake by athletes has no harmful consequences on renal function. This study investigated body-builders (BB) and other well-trained athletes (OA) with high and medium protein intake, respectively, in order to shed light on this issue.
The athletes underwent a 7-day nutrition record analysis as well as blood sample and urine collection to determine the potential renal consequences of a high protein intake.
The data revealed that despite higher plasma concentration of uric acid and calcium, Group BB had renal clearances of creatinine, urea, and albumin that were within the normal range.
The nitrogen balance for both groups became positive when daily protein intake exceeded 1.26 g x kg-1 but there were no correlations between protein intake and creatinine clearance, albumin excretion rate, calcium excretion rate.
To conclude, it appears that protein intake under 2.8 g x kg-1 does not impair renal function in well-trained athletes as indicated by the measures of renal function used in this study.
