The Claim

In adults with stage 3–4 chronic kidney disease, consuming at least 30 unique plant foods per week for six weeks reduces potential renal acid load by an average of 47% and slows kidney function decline through mitigation of chronic metabolic acidosis.

Cause and effect
1 study reviewed
In plain English

Adults with moderate to severe kidney disease who eat at least 30 different plant foods each week for six weeks experience a 47% reduction in potential renal acid load and a slower decline in kidney function due to reduced metabolic acidosis.

See the scientific wording

In adults with stage 3–4 chronic kidney disease, consuming at least 30 unique plant foods per week for six weeks significantly reduces potential renal acid load by an average of 47%, which may slow kidney function decline by mitigating chronic metabolic acidosis.

Why this might work

Eating many different plant foods increases good gut bacteria that turn fiber into butyrate, which enters the blood. At the same time, plant foods release organic acids like citrate and malate that the body converts into bicarbonate. This bicarbonate neutralizes acid in the blood, so the kidneys don't have to work as hard to remove acid. Less acid burden lets the kidneys function better and slows damage.

  1. Study: High-Diversity Plant-Based Diet and Gut Microbiome, Plasma Metabolome, and Symptoms in Adults with CKD

    Eating at least 30 different kinds of plant foods each week for six weeks helped people with moderate kidney disease reduce the acid burden on their kidneys by nearly half, according to a well-designed study. This could help their kidneys work better and feel less stressed.
