Sarcopenia modifies the association between diet quality and cognitive function in community-dwelling older people: a cross-sectional study

This study highlights an interaction between diet quality and sarcopenia in relation to cognitive function. Higher diet quality was associated with better cognitive performance, but this association appeared weaker among individuals with more severe sarcopenia. Given the cross-sectional design, causality and directionality cannot be inferred; longitudinal and interventional studies are warranted to confirm these findings and inform prevention strategies.
