研究问题
The present hypothesis does not depend on whether Okinawa had a longevity advantage before World War II; it rests on the postwar pattern described below.
方法
Individual nutritional trajectories were not measured; cohorts were assigned to approximate trajectories on the basis of the nutritional environments prevailing in different historical periods, and considerable heterogeneity existed within each cohort.
核心结论
However, persistent nutritional restraint could eventually become disadvantageous if nutritional and physiological reserves become insufficient as individuals age or face illness [15,16]. ‖ 结论：These historical observations suggest a unified interpretation.
局限
全文未设独立 limitations 节；结构上为综述/二次研究，因果推断强度受限。
对本项目的价值
★★☆☆☆ 干预证据决定参照标准效应量——任何抗衰干预的收益至少应对标该基线。设计 Meta 分析、横断面。
