Slim Down this Summer

In another of Atkins Diet Misconception series, I deal with the question of kidney stones or “does the Atkins Diet impair kidney function?” First, if you have damaged kidney function already due to Chronic Kidney Disease, Metabolic disorder, or impaired kidney function, it is recommended that you do not try the Atkins Diet. There is sizable water intake on this diet, and you should follow your doctor’s orders. For everyone else, it has been proved more than once that high protein (or medium protein in the case of Atkins) is safe for kidney function.

Those that rail against it have been doctors with bias (PCRM (PETA) related doctors or have relied on bad science studies where multiple items were changed at once. Studies supporting the idea of high protein being safe for HEALTHY people’s kidneys:

Dietary protein intake and renal function
“”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. … Rather, we found that habitual consumption of a high protein diet minimally affected hydration indices. … Therefore, claims that a high protein diet promotes dehydration or adversely “strains” the kidney remain speculative.”

“Do regular high protein diets have potential health risks on kidney function in athletes?”

To conclude, 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. For example, Nguyen et al. found that high intakes of animal protein adversely affected markers of stone formation in those afflicted with a stone causing disorder, while no changes were observed in healthy individuals. It has been suggested that one must have a preexisting metabolic dysfunction before dietary protein can exert an effect relative to stone formation.

Dietary factors and the risk of incident kidney stones in men: new insights after 14 years of follow-up.
Clinical journal of the American Society of Nephrology – Dec 2004
“Animal protein was associated with risk only in men with a body mass index less than 25.”
