BackgroundThe Mediterranean diet (MD) is an ancient eating habit that is believed to contribute to a healthy lifestyle. Unsurprisingly, research on the MD is growing rapidly as people pay more attention to health preservation and prevention, treatment and rehabilitation of chronic diseases. Previous reviews focused more on the effects of MD on a particular disease which has enhanced its significance in the medicine field. However, few studies have attempted to provide a comprehensive summary and analysis of this topic. This study evaluates the global research trends of scientific outputs related to MD from multiple perspectives, using a bibliometric analysis and visualization tool (CiteSpace software) to scientifically analyze the knowledge from the literature.MethodsThe core collection database of Web of Science was used to retrieve the bibliographic records related to MD from 1984 to March 30, 2021. CiteSpace was used to generate and analyze visual representations of the complex data input, including number of publications, research performances in journals, authors, institutions, countries and co-occurrence networks of keywords and co-citation references.ResultsOverall, the number of MD publications has shown a significant upward trend since 2012. Nutrients and American Journal of Clinical Nutrition contained the most articles related to MD, indicating that they were important platforms for related research. Martinez-gonzalez Ma and Estruch Ramon are the authors with the highest number of publications related to MD, and it is noteworthy that these 2 authors have close cooperation in this field. The countries with the most publications are Spain and the United States, and the institutions with the most publications are Univ Navarra, Inst Salud Carlos III. The main research disciplines are "Mediterranean diet," "risk," "cardiovascular disease," "adherence," "obesity," "coronary heart disease," "diet," "health," "physical activity" and "risk factor". Estruch R's 2013 study on cerebrovascular disease and Tricopoulou A's 2003 mortality study were cited 881 cases for 437 times, respectively, showing the importance of these 2 articles in this field.ConclusionThe current global trends of MD research as well as people's increasing awareness of healthcare and healthy lifestyle imply that MD research is expected to become increasingly popular with further breakthroughs.Copyright © 2021 the Author(s).
