Daily intake of live microbes and cognitive function in older adults: the mediating role of mitochondrial dysfunction

This study analysed the NHANES (2010-2014) data of 2,312 elderly people to investigate the relationship between dietary intake of live microbes (DLM) and cognitive function and the mediating role of mitochondrial dysfunction between them. Linear regression indicated that the high-DLM group was positively associated with z-score of Digit Symbol Substitution Test (DSST) (β = 0.13, p p p p
