Paper

Abstract

Although dietary diversity (DD) has been confirmed to be associated with multiple health outcomes and longevity in older people, the related mechanisms have not been elucidated. In this study, we explored the mediating roles of physical activities and cognitive function in the relationship between DD and all-cause mortality.

Research summary

The paper investigates the relationship between dietary diversity and all-cause mortality in older adults, focusing on mediating factors such as physical activity and cognitive function. While it addresses aspects of longevity and health outcomes in aging populations, the study primarily explores associations rather than root causes of aging or mechanisms for lifespan extension. Therefore, it contributes solid research but has limited impact on the broader field of longevity research.
