Total phenolic compounds in plant-based beverages consumed in latin america: protocol for a systematic review

Introduction. Latin America is one of the regions with the highest concentration of biodiversity. Plant-based beverages hold a special place in culture, identity, and food heritage. Currently, these beverages have sparked great interest in the scientific community, the market, industry, and consumers because they are considered nutritional and potentially functional sources due to the presence of bioactive compounds such as polyphenols. Multiple studies have linked the protective effect of these compounds against adverse health events; however, no studies are known to have reviewed the polyphenol content of plant-based beverages in the region. Objective. To provide an overview of the total phenolic content of plant-based beverages consumed in Latin American countries. Methods. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) 2015 statement guided this protocol. Observational or experimental studies that evaluated total phenolic compounds in plant-based beverages consumed in Latin America will be included. Articles that estimate the total phenolic compounds in beverages, including juices and infusions, will be included. Electronic search strategies will be developed for the following bibliographic databases: ScienceDirect, PubMed/MEDLINE, LILACS, and Scopus. The search strategy and selection process results will be presented in a flow chart and summarized in the text. The main results will be presented in a descriptive synthesis. Results. The main results will be presented in a descriptive synthesis. The review of the databases is expected to be completed in December 2025. Conclusions: This review will provide a synthesis of the total phenolic content in plant-based beverages consumed in Latin America. Funding. Financial support of the Universidad Industrial de Santander (number 4264).
