Box plots of change of urine albumin (mg)-to-creatinine (g) ratio (Ualb) for the three groups of subjects with estimated glomerular filtration rate (eGFR) >90ml/min (CKD 1) and eGFR 60–90ml/min (CKD 2). CKD, chronic kidney disease; F+V, subjects given fruits+vegetables for 30 days; HCO3, subjects given oral NaHCO3 daily for 30 days; Time Control, subjects followed up for 30 days with no further intervention. *P<0.05 versus Time Control; +P<0.05 versus HCO3.

Outline of the protocol to test the effect after 30 days on parameters of kidney injury of no intervention (Time Control), daily oral NaHCO3 at a concentration of 0.5 mEq/kg bw/day, or fruits+vegetables given in amounts designed to reduce dietary acid intake by 50%.
