A review of the potential health benefits of plant-based diets in patients with CKD found growing evidence, mostly observational, that in individuals with estimated GFR of 30–59 ml/min per 1.73 m2, plant-based diets (eg, Dietary Approaches to Stop Hypertension [DASH] diet, Mediterranean diet) may delay progression to ESRD and dialysis and may potentially improve survival. [93, 94]

A study by Goraya et al showed that increasing the amount of alkali-inducing fruits and vegetables in the diet may help to reduce kidney injury. [95] In this report, 30 days of a diet that included fruits and vegetables, in amounts calculated to reduce dietary acid by half, resulted in decreased urinary albumin, N-acetyl β-D-glucosaminidase, and transforming growth factor β in patients with moderately reduced estimated GFR as a result of hypertensive nephropathy. [95]
