Association between probiotic and yogurt consumption and kidney disease: insights from NHANES.

Background: Data from experimental animals suggest that probiotic supplements may retard CKD progression. However, the relationship between probiotic use, frequent yogurt consumption (as a natural probiotic source), and kidney parameters have not been evaluated in humans.

Findings: We utilized NHANES data, and analyzed the association of probiotic alone (1999-2012) and yogurt/probiotic (2003-2006) use with albuminuria and eGFR after adjustment for demographic and clinical parameters.
