Dietary Acid Reduction and Progression of Chronic Kidney Disease

Participants will receive a prescribed amount of F+V designed to reduce their dietary acid intake by half. This typically amounts to 2-4 cups/day for each participant randomized to this group, depending on the type of F+Vs used, provided in weekly allotments. Participants will receive standard care for their medical concerns.

Participants will receive 0.4 mEq/kg bw NaHCO3 /day, an amount designed to match the alkali provided by the added F+V. This will be provided as 650 mg NaHCO3 tablets for an average of 4-5 tablets/day in 2 divided doses for each participant randomized to this group. Participants will receive standard care for their medical concerns.

Participants will receive standard care for their medical concerns and no additional alkali (F+V or NaHCO3).
