保守的基因和途径,调节寿命,但也健康寿命的鉴定,导致营养素,信号转导蛋白和衰老之间的联系的理解有所提高,但也提供了证据,存在多个“长寿计划”,这是选择的基础上的可用性的营养素。定期禁食和其他饮食限制可以促进进入以细胞保护和最佳功能为特征的长期长寿计划,但也可以激活导致年轻化的再生过程,这与限制期之前的衰老率无关。因此,基于“青年学”的策略可以补充传统的老年学方法,不关注衰老,而是关注影响生命史时期的长寿计划,在这个时期,死亡率非常低,生物体保持年轻,健康和功能齐全。
The identification of conserved genes and pathways that regulate lifespan but also healthspan has resulted in an improved understanding of the link between nutrients, signal transduction proteins, and aging but has also provided evidence for the existence of multiple “longevity programs,” which are selected based on the availability of nutrients. Periodic fasting and other dietary restrictions can promote entry into a long‐lasting longevity program characterized by cellular protection and optimal function but can also activate regenerative processes that lead to rejuvenation, which are independent of the aging rate preceding the restricted period. Thus, a “juventology”‐based strategy can complement the traditional gerontology approach by focusing not on aging but on the longevity program affecting the life history period in which mortality is very low and organisms remain youthful, healthy, and fully functional.
