Diet has been recognized as a vital risk factor for non-communicable diseases (NCDs), climate changes, and increasing population, which has been reflected by a rapidly growing body of the literature related to healthy eating. To reveal a panorama of the topics related to healthy eating, this study aimed to characterize and visualize the knowledge structure, hotspots, and trends in this field over the past two decades through bibliometric analyses. Publications related to healthy eating between 1 January 2002 and 31 December 2021 were retrieved and extracted from the Web of Science database. The characteristics of articles including publication years, journals, authors, institutions, countries/regions, references, and keywords were assessed. The analyses on co-authorship, co-occurrence, and co-citation were performed and network visualization maps were constructed by VOSviewer. Major subdomains identified by bibliometrics were further discussed and analyzed. A total of 12,442 articles on healthy eating were identified. Over the past two decades, the annual global publications increased from 71 to 1764, showing a nearly 25-fold growth. The journal Nutrients published the most articles and The American Journal of Clinical Nutrition possessed the highest citations. The United States, Harvard University, and Hu, Frank B. were identified as the most productive and influential country, institution, and author, respectively. The co-occurrence cluster analysis of the top 100 keywords formed four clusters: (1) the food insecurity environment for youths highlighting the necessity and significance of implementing healthy eating in early life; (2) sustainable advantages of the Mediterranean diet; (3) the importance of an overall healthy lifestyle optimization leveraged by eHealth; (4) the challenges during the course of healthy eating against obesity, which are prominent in reflecting the knowledge structure, hotspots, and trends. Moreover, COVID-19, orthorexia nervosa, sustainability, microbiota, food insecurity, and e-health are identified keywords that represented the latest high-frequency keywords and indicated the emerging frontiers of healthy eating. This study indicates that the number of publications on healthy eating will increase in the future and that healthy dietary patterns and clinical applications of healthy eating will be the next hotspots in this research field.

The association between egg consumption and diabetes is inconclusive. We aimed to examine the association between long-term egg consumption and its trajectory with diabetes in Chinese adults. A total of 8545 adults aged ≥18 years old who attended the China Health and Nutrition Survey from 1991 to 2009 were included in this analysis. Egg consumption at each survey was assessed by a 3-d 24-h recall and weighed food record methods. The consumption trajectories of eggs were modelled with the latent class group approach. Diabetes was diagnosed based on fasting blood glucose in 2009. Logistic regression was used to examine the association. The mean age of the study population was 50·9 (sd 15·1) years. About 11·1 % had diabetes in 2009. Egg consumption nearly doubled in 2009 from 16 g/d in 1991. Compared with the first quartile of egg consumption (0–9·0 g/d), the adjusted OR of diabetes for the second (9·1–20·6 g/d), third (20·7–37·5 g/d) and fourth (≥37·6 g/d) quartiles were 1·29 (95 % CI 1·03, 1·62), 1·37 (95 % CI 1·09, 1·72) and 1·25 (95 % CI 1·04, 1·64), respectively (Pfor trend = 0·029). Three trajectory groups of egg consumption were identified. Compared with group 1 (30·7 %, low baseline intake and slight increase), both group 2 (62·2 %, medium baseline intake and increase) and group 3 (7·1 %, high baseline intake and decrease) were associated with an increased OR for diabetes. The results suggested that higher egg consumption was positively associated with the risk of diabetes in Chinese adults.

Aims: Chronic liver disease (CLD) is increasingly recognized as a significant global public health threat, with morbidity and mortality rates remaining high. Evidence suggests that sarcopenia independently increases the risk of CLD and negatively impacts various clinical outcomes, including survival, quality of life, and the emergence of additional complications in patients with CLD. This study aimed to give a bibliometric analysis to examine the correlation between sarcopenia and CLD from a literature perspective.Methods: To understand the structure of this research field, we employed VOSviewer. The research on the correlation between long‐term liver disease and sarcopenia was obtained from the Web of Science Core Collection. VOSviewer 1.6.19.0 was utilized to examine and illustrate these publications, encompassing yearly patterns in the domain, focal points of research, significant articles, authors, journals, and organizations. Moreover, according to the results of the cluster analysis of keywords, we further searched and classified related studies to discuss.Results: This study provides a comprehensive analysis of current research trends, international collaboration models, fundamental understandings, key focus areas, and future research areas in the field of sarcopenia and CLD by reviewing publications from January 1, 2000 to December 31, 2023. Over the past 24 years, research in the field of sarcopenia and CLD has deepened, with a gradual increase in publications and citations from various countries, institutions, and authors. Keyword analysis of sarcopenia and CLD indicates that current research predominantly focuses on several key areas, including obesity, metabolic syndrome, hepatic steatosis, insulin resistance, inflammation, and nutrition therapy.Conclusion: This study provided a visual representation of the current research on the correlation between CLD and sarcopenia, including publication trends, global collaboration patterns, and research hotspots. This research contributes significantly by summarizing and discussing current research trends in sarcopenia and CLD, offering valuable insights into the complex relationship, and highlighting research trends, collaborations, and future directions in clinical treatment.
