Comparative effects of low-carbohydrate high-protein versus low-fat diets on the kidney

URL: https://www.ncbi.nlm.nih.gov/m/pubmed/22653255/

Journal: CJASN

Publication Date: 07/2012

Summary: 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.

Key Takeaways

Another set of data showing high protein diets do not cause kidney dysfunction.

Dietary Oxalate and Calcium Oxalate Nephrolithiasis

URL: https://www.auajournals.org/doi/abs/10.1016/j.juro.2007.06.046

Journal: Journal of Urology

Publication Date: 11/2007

Summary: Rats fed an oxalate precursor developed renal oxalate stones. When the oxalate precursor was removed from the diet, the oxalate crystals resolved.

Key Takeaways

Oxalates are crystals found in plant foods such as spinach, potatoes, nuts, etc. that can deposit in tissues and cause pain or bind to calcium and produce kidney stones. When oxalate precursors were fed to rats they developed kidney stones, and then when they were no longer fed the oxalate precursors the stones went away.

Dietary protein intake and renal function

URL: https://www.ncbi.nlm.nih.gov/m/pubmed/16174292/

Journal: Nutrition & Metabolism

Publication Date: 09/2005

Summary: 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.

Key Takeaways

High protein diets have not been shown to have negative health effects in healthy people.

Human renal response to meat meal

Journal: American Journal of Physiology – Renal Physiology

Publication Date: 04/1986

Summary: The response of eating a meat meal on kidney function was measured in 10 healthy volunteers. Kidney function (GFR) and renal blood/plasma flow increased in most (8/10) subjects, although the amount increase was not statistically significant.

Key Takeaways

Eating a meat meal showed an increase in blood flow through the kidneys but it was not statistically significant.
