Abstract

Accelerated global population aging has heightened cognitive impairment as a critical public health challenge. Emerging evidence implicates gut microbiota in cognitive regulation via the gut-brain axis, with diet being a key modifiable factor. The Dietary Index for Gut Microbiota (DI-GM) quantifies diet-microbiota interactions, but its link to cognition remains unexplored. This study investigated the DI-GM-cognition relationship in older adults and evaluated its predictive value for cognitive impairment.

Research summary

The paper claims that the Dietary Index for Gut Microbiota (DI-GM) is associated with cognitive function in older adults. This research is relevant as it explores the relationship between diet, gut microbiota, and cognitive health, which are important factors in understanding and potentially mitigating age-related cognitive decline.
