This was a 3-year trial that randomized 108 people with stage-3 chronic kidney disease and mild metabolic acidosis (22 mmol/l < plasma TCO2 < 24 mmol/l) to three different groups: added fruit and vegetables, oral NaHCO 30.3 mEq/Kg in three divided doses per day, and usual care.
Compared to baseline, TCO2 decreased in the usual care group, and increased in the fruit and vegetable group and the NaHCO group, representing positive changes in metabolic acidosis. The effect of the fruit and vegetables group was not significantly different from the NaHCO group, and both were significantly different from usual care. The change in renal acid load as measured by 8-hour urine net-acid excretion from baseline decreased only in the fruit and vegetable group.
