Precision nutrition is a potentially disruptive paradigm of nutritional science that seeks to precisely customize food advice depending on the biological, genetic, environmental, and lifestyle factors of individuals. The intensive research growth in human and animal nutrition, nutrigenomics, metabolomics and data-driven methods has produced a convoluted and multidisciplinary literature that is difficult to synthesize in terms of conventional narrative methods. The current paper presents a combined bibliometric and scientmetric review of the world-wide research on precision nutrition published in PubMed index between 2005 and 2025 which incorporates the performance analysis, science mapping and multivariate conceptual approaches. One hundred and thirty-two publications were analyzed in 81 sources with the help of Bibliometrix R package and VOSviewer. Temporal analysis indicated that the output of research has increased significantly since 2015 as a result of increasing use of omics technologies, microbiome research, and computational analytics. The source analysis revealed that there is a high concentration of journal that has a few core nutrition journals that cover a huge percentage of the publications, which is in line with the law of Bradford. The geographic evaluation showed that the high-income nations, especially the United States and Western Europe, had been dominant, with a moderate yet growing cooperation at the international level. The keywords co-occurrence networks, density mapping, and overlay visualization revealed diet-health interaction, nutrigenomics, and human nutritional status as the key themes of research, whereas artificial intelligence and microbiome-based personalization and precision feeding in animals became emerging directions. Several correspondence analyses also showed the specific conceptual axes between molecular and omics-oriented research on the one hand and, on the other hand, applied and preventive nutrition areas. All the results point to parallel, but still not fully integrated processes of human and animal precision nutrition studies. The paper has provided a strategic overview of intellectual, thematic, and future directions of the field of precision nutrition, which offers a solid evidence base to guide interdisciplinary research, translational implementation, and policy formulation.
