Abstract

Tea is widely consumed worldwide and increasingly studied for its bioactive components and associations with nutrition, metabolic health, and chronic disease risk, yet global research patterns remain insufficiently summarized. This study aimed to map global research trends and thematic structures in tea consumption research using bibliometric analysis. Publications indexed in the Scopus database from 2017 to 2026 were retrieved using the keywords “tea” AND “consumption.” A total of 2,376 documents from 1,005 sources were analyzed using Biblioshiny (Bibliometrix package in RStudio), supported by Microsoft Excel and Minitab. The analysis examined publication trends, citation impact, leading countries and institutions, journal sources, keyword co-occurrence, and conceptual structure. The results show a substantial growth in scientific output, dominated by original articles and reviews, with research focusing on humans, nutrition, caffeine, obesity, and metabolic health. China is the leading contributor, and Nutrients is the most productive journal. The strongest keywords are humans, tea consumption, nutrition, caffeine, obesity, and metabolic health, reflecting a dominant focus on population-based dietary research and public health outcomes. Overall, tea consumption research is a mature and collaborative field within public health and nutrition.
