Diet: High-Protein Diet May Harm Kidneys.

After two months on a high-protein, low-carbohydrate (HPLC) diet, rat subjects had creatinin blood levels 54.5% higher than rats fed either a low-fat, low-protein diet or a diet resembling the standard Western diet. Creatinin is a waste product typically expelled from the body by the kidneys. Elevated levels of creatinin in the blood are indicative of compromised kidney function, which suggests that too much protein in a diet may be detrimental to the body. Further research is needed to determine if such a diet leads to similar outcomes in humans. Environmental Toxicology and Pharmacology, January 2015
