Effects of protein intake on the progression of renal disease

In summary, protein restriction appears to be of benefit in certain types of renal disease. Studies measuring GFR and using a concomitant control group are necessary to answer this question with certainty, however. The mechanisms by which changes in dietary protein influence the progression of renal insufficiency have not been defined. Further studies are needed to identify those patients and renal diseases that may benefit from dietary restriction of protein. Long-term studies designed to assess carefully the nutritional impact of prolonged periods of protein restriction on individuals with renal insufficiency are also required.
