Abstract excerpt

BACKGROUND: Aging is closely linked to chronic diseases, and gut microbiota plays a significant role in this process. The Dietary Index for Gut Microbiota (DI-GM), a novel tool reflecting the potential impact of diet on gut microbiota diversity, has an unclear association with biological aging. This study aimed to evaluate the association between DI-GM and phenotypic age acceleration (PAA), revealing the...
