BACKGROUND: Several bibliometric analyses have been carried out to identify research hotspots and trends in nonalcoholic fatty liver disease (NAFLD) research. Nonetheless, there are still significant knowledge gaps that must be filled to advance our understanding of and ability to treat NAFLD. AIM: To evaluate, through bibliometric and visual analysis, the current status of related research, related research frontiers, and the developmental trends in the field of diet and NAFLD. METHODS: We retrieved publications about diet and NAFLD published between 1987 and 2022 from Scopus. Next, we used VOSviewer 1.6.20 to perform bibliometric analysis and visualization. RESULTS: We found a total of 1905 studies, including 1637 (85.93%) original articles and 195 (10.24%) reviews, focused on the examination of NAFLD and its correlation with diet that were published between 1987 and 2022. Among the remaining five types of documents, 38 were letters, notes, editorials, meeting minutes, or brief surveys, representing 1.99% of the total documents. The countries with the most publications on this topic were China ( = 539; 28.29%), followed by the United States ( = 379; 19.90%), Japan ( = 133; 6.98%), and South Korea ( = 127; 6.6%). According to the citation analysis, the retrieved papers were cited an average of 32.3 times and had an -index of 106, with 61014 total citations. The two main clusters on the map included those related to: (1) Inflammation and oxidative stress; and (2) Dietary interventions for NAFLD. CONCLUSION: This was the first study to use data taken from Scopus to visualize network mapping in a novel bibliometric analysis of studies focused on diet and NAFLD. After 2017, the two domains that received the most attention were "dietary interventions for NAFL"' and "'inflammation and oxidative stress implicated in NAFLD and its correlation with diet." We believe that this study provides important information for academics, dietitians, and doctors, and that additional research on dietary interventions and NAFLD is warranted.
背景：已有多项文献计量分析旨在确定非酒精性脂肪性肝病（NAFLD）研究中的热点和趋势。然而，仍存在重大的知识空白，需要加以填补，以增进我们对 NAFLD 的理解并提高治疗能力。
目的：通过文献计量和可视化分析，评估饮食与 NAFLD 相关研究的现状、相关研究前沿和该领域的发展趋势。
方法：我们从 Scopus 中检索了 1987 年至 2022 年间发表的关于饮食与 NAFLD 的出版物。然后，我们使用 VOSviewer 1.6.20 进行文献计量分析和可视化。
结果：我们共发现 1905 项研究，其中 1637 项（85.93%）为原始文章，195 项（10.24%）为综述，重点研究了 NAFLD 及其与饮食的相关性，这些研究发表于 1987 年至 2022 年间。在其余五种类型的文献中，有 38 篇为信件、注释、社论、会议记录或简要调查，占文献总数的 1.99%。在这一主题上发表文献最多的国家是中国（ = 539；28.29%），其次是美国（ = 379；19.90%）、日本（ = 133；6.98%）和韩国（ = 127；6.6%）。根据引文分析，检索到的论文平均被引 32.3 次，-index 为 106，总引文数为 61014。图谱上的两个主要聚类包括：（1）炎症和氧化应激；（2）NAFLD 的饮食干预。
结论：这是首次使用 Scopus 数据进行可视化网络映射，对以饮食与 NAFLD 为重点的研究进行新的文献计量分析。2017 年后，受到最多关注的两个领域是“NAFLD 的饮食干预”和“炎症和氧化应激与 NAFLD 及其与饮食的相关性”。我们认为，本研究为学者、营养师和医生提供了重要信息，有必要进一步研究饮食干预和 NAFLD。
