BACKGROUND: According to national guidelines, a diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) is a second-line therapy option for irritable bowel syndrome (IBS) and improves functional intestinal symptoms. Numerous noteworthy results have been published in this field over the past fifteen years. This study aims to analyze the global research trend and hotspot of the low FODMAP diet research, and provide a comprehensive perspective and direction for researchers. METHODS: The Science Citation Index-Expanded of the Web of Science Core Collection (WoSCC) was used to identify low FODMAP diet-related articles and reviews. Three bibliometric programs (CiteSpace, VOSviewer, Scimago Graphic) were utilized to analyze and visualize the annual publications, authors, countries, institutions, journals, citations, and keywords. RESULTS: In total, 843 documents related to the low FODMAP diet research were published in 227 journals by 3,343 authors in 1,233 institutions from 59 countries. The United States, which was the most engaged nation in international collaboration, had the largest annual production and the fastest growth. The most productive organization was Monash University, and the most fruitful researcher was Gibson PR. Nutrients ranked first in terms of the number of published documents. The article "A diet low in FODMAPs reduces symptoms of irritable bowel syndrome" (Halmos EP, 2014) received the most co-citations. Keywords that appear frequently in the literature mainly involve two main aspects: the clinical efficacy evaluation and mechanism exploration of the low FODMAP diet. The term "gut microbiota" stands out as the most prominent keyword among the burst keywords that have remained prevalent till date. CONCLUSION: The restriction stage of the low FODMAP diet is superior to other dietary therapies for IBS in terms of symptom response, but it has a negative impact on the abundance of gut Bifidobacteria and diet quality. Identification of biomarkers to predict response to the low FODMAP diet is of great interest and has become the current research hotspot.
背景:根据国家指南,低发酵寡糖、双糖、单糖和多元醇(FODMAP)饮食是肠易激综合征(IBS)的二线治疗选择,可改善功能性肠道症状。在过去的十五年中,该领域发表了许多有意义的研究结果。本研究旨在分析低 FODMAP 饮食研究的全球研究趋势和热点,为研究人员提供全面的视角和方向。
方法:本研究使用 Web of Science 核心合集(WoSCC)的科学引文索引扩展版来确定低 FODMAP 饮食相关文章和综述。使用三个文献计量学程序(CiteSpace、VOSviewer、Scimago Graphic)分析和可视化年度出版物、作者、国家、机构、期刊、引文和关键词。
结果:共发表了 843 篇与低 FODMAP 饮食研究相关的文献,涉及 59 个国家的 1233 个机构的 3343 位作者,发表在 227 种期刊上。美国是国际合作最活跃的国家,拥有最大的年度产量和最快的增长速度。最具生产力的机构是莫纳什大学,最有成果的研究人员是 Gibson PR。营养素在发表文献数量上排名第一。文献中出现频率较高的关键词主要涉及低 FODMAP 饮食的临床疗效评价和机制探索两个主要方面。“肠道微生物群”是目前为止一直很热门的突发关键词中最突出的关键词。
结论:低 FODMAP 饮食的限制阶段在症状反应方面优于其他 IBS 饮食疗法,但对肠道双歧杆菌的丰度和饮食质量有负面影响。识别预测对低 FODMAP 饮食反应的生物标志物是非常有意义的,并且已经成为当前的研究热点。
