Preliminary bibliometrics of plant-derived health foods over the last decade in the Scopus database

Abstract

A growing interest in the medicinal values of foods can be assessed by the rapidity of research publications on foods that exert health  benefits. Many foods that are of health benefit to humans, irrespective of their origin (plants, animals) and subjected level of processing  (fermentation, cooking, warming, freezing, vacuumpackaging), are variously designated in scientific literature based on their biofunction.  Plant-based foods’ application vagaries, momentum, and research orientation regarding their health functionality  awareness are scarcely studied by bibliometrics from a global perspective. Therefore, a bibliometric search was performed on the Scopus  database from 2011 (January) to 2021 (April) using a range of search keys covering reports of conceptualized consumable plant-derived foods with health-promoting potential. A total of 362,309 documents on medicinal foods of plant origin were obtained from the database.  The data were obtained in comma-separated values (CSV) format and analyzed with Microsoft Excel tools. Of the total  documents from the Scopus database on the study, 8.01% (29,036) were contributed by African researchers. Comparatively, lead  contributors (global; Africa) by group disciplines include biochemistry, genetics, and molecular biology (118,896; 8,236); pharmacology,  toxicology, and pharmaceutics (104,530; 8,581); agricultural and biological sciences (99,053; 9,610), respectively. Similarly, lead contributors by country include China (73,977), India (44,898), USA (44,582), and Nigeria (4,680). This observation shows a higher research  propensity towards plant-derived medicinal foods in populous nations due to factors like dietary culture, an increase in vegan  and health-nutrition enthusiast populations, and the emergent concerns with the therapeutic use of synthetic pharmaceuticals. The analyzed results gave insights into the research orientation of plant-based foods that promote human health on a global stage and  provide future research directions. Knowledge of the various application of plant-based foods may potentiate the United Nations  Sustainable Goals initiative on responsible consumption (SDG 12), and health and wellbeing (SDG 3) among the global population.
