Research by Johnson et al. [54], showed protein intake as
a possible risk factor for progressive loss of remaining
renal function in dialysis patients. Indeed, dietary protein
restriction is a common treatment modality for patients
with renal disease [55,56] and practice guidelines exist
regarding reduced dietary protein intakes for individuals
with chronic renal disease in which proteinuria is present
[57]. The National Kidney Foundation (NKF) has extensive
recommendations with regard to protein intake,
which are a byproduct of the Dialysis Outcome Quality
Initiative [58]. Again, it is important to note that these recommendations
are not indicated for individuals with normal
renal function nor are they intended to serve as a
prevention strategy to avoid developing CKD. Despite the
clarity of these guidelines, their mere existence has
resulted in concern regarding the role of dietary protein in
the onset or progression of renal disease in the general
population [59].
