Abstract
- Cellular senescence, a process in which a cell exits the cell cycle in response to stressors, is one of the hallmarks of aging. Senescence and the senescence-associated secretory phenotype (SASP)—a heterogeneous set of secreted factors that disrupt tissue homeostasis and promote the accumulation of senescent cells—reprogram metabolism and can lead to metabolic dysfunction. Dietary interventions have long been studied as methods to combat age-associated metabolic dysfunction, promote health, and increase lifespan. A growing body of literature suggests that senescence is responsive to diet, both to calories and specific dietary macronutrients, and that the metabolic benefits of dietary interventions may arise in part through reducing senescence. Here, we review what is currently known about dietary macronutrients' effect on senescence and the SASP, the nutrient-responsive molecular mechanisms that may mediate these effects, and the potential for these findings to inform the development of a nutrigeroscience approach to healthy aging. Calubag et al. review recent findings that suggest dietary composition plays an important role in regulating senescence. The authors discuss molecular mechanisms engaged by altered macronutrient diets and the potential for these findings to inform a nutrigeroscience approach to aging. [ABSTRACT FROM AUTHOR]
