Too Much Protein??

Media sources often report, “too much protein stresses the kidney.” What does science say? Martin and colleagues reviewed the available evidence regarding the effects of protein intake on kidney function with a particular emphasis on kidney disease. The researchers found: “Although excessive protein intake remains a health concern in individuals with preexisting renal disease, the literature lacks significant research demonstrating a link between protein intake and the initiation or progression of renal disease in healthy individuals.” In addition “At present, there is not sufficient proof to warrant public health directives aimed at restricting dietary protein intake in healthy adults for the purpose of preserving renal function.” Protein restriction is common treatment for people with kidney problems.
