High-protein diet OK for kidney

[Guest guest]

Hi All,

See the below pdf-free for all paper that seems to suggest high-protein diets

spare

kidney damage.

Much of the basis for recommending the high-protein diet seems to rest in the

pdf-available paper:

Cordain L, Eaton SB, Sebastian A, Mann N, Lindeberg S, Watkins BA, O'Keefe JH,

Brand- J.

Origins and evolution of the Western diet: health implications for the 21st

century.

Now, here is the pdf-free-for-all paper.

Dietary Protein Intake and Renal Function.

Recent trends in weight loss diets have led to a substantial increase in

protein

intake by individuals. As a result, the safety of habitually consuming dietary

protein in excess of recommended intakes has been questioned. In particular,

there

is concern that high protein intake may promote renal damage by chronically

increasing glomerular pressure and hyperfiltration. There is, however, a serious

question as to whether there is significant evidence to support this

relationship in

healthy individuals. In fact, some studies suggest that hyperfiltration, the

purported mechanism for renal damage, is a normal adaptative mechanism that

occurs

in response to several physiological conditions. This paper reviews the

available

evidence that increased dietary protein intake is a health concern in terms of

the

potential to initiate or promote renal disease. 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.
