: The global population is rapidly aging, raising interest in dietary practices for promoting the healthspan. This study aimed to comprehensively investigate the state of diet and longevity research over the past decade, addressing the lack of bibliometric synthesis within the field. : A bibliometric analysis was performed using the keywords "diet" and "longevity" on English-language articles from the Web of Science database that were published from 2015 to 2024. Data were analyzed using Web of Science tools, InCites, and VOSviewer to identify trends in publication output, citation metrics, coauthorship networks, institutional contributions, and keyword co-occurrence patterns. : Overall, 2203 articles meeting the inclusion criteria were included in the analysis. Publication volume and citation counts gradually increased, peaking in 2021. Countries, including the United Kingdom, and organizations, such as the National Institutes of Health and Harvard University, had significant citation impact, and the United States and China led productivity. Molecular processes (oxidative stress and autophagy), dietary models (Mediterranean diet and calorie restriction), and public health issues (obesity and mortality) were the main thematic clusters. Model species, including and , were frequently used. Regional disparities in research production and notable terminology variability were noted. : This study emphasizes the development and diversity of nutrition and longevity research while highlighting novel molecular and translational topics. More international cooperation, uniform language, and multidisciplinary frameworks are warranted to promote equal scientific advancement worldwide and connect mechanistic discoveries with therapeutic outcomes.
全球人口正在迅速老龄化，这引发了人们对促进健康寿命的饮食习惯的兴趣。本研究旨在全面调查过去十年饮食与长寿研究的状况，以解决该领域缺乏文献计量综合分析的问题。
使用关键词“饮食”和“长寿”对2015年至2024年发表在科学网数据库上的英文文章进行文献计量分析。使用科学网工具、InCites和VOSviewer对数据进行分析，以确定出版物产出、引用指标、共同作者网络、机构贡献和关键词共现模式的趋势。
总体而言，共有2203篇符合纳入标准的文章被纳入分析。出版物数量和引用次数逐渐增加，在2021年达到峰值。包括英国在内的国家以及美国国立卫生研究院和哈佛大学等组织具有显著的引用影响力，美国和中国在研究产出方面领先。分子过程（氧化应激和自噬）、饮食模式（地中海饮食和热量限制）以及公共卫生问题（肥胖和死亡率）是主要的主题集群。经常使用包括[具体物种1]和[具体物种2]在内的模式物种。研究产出存在区域差异，术语也有显著变化。
本研究强调了营养与长寿研究的发展和多样性，同时突出了新的分子和转化研究主题。需要更多的国际合作、统一的语言和多学科框架，以促进全球科学的平等进步，并将机制发现与治疗结果联系起来。
