Summary
Phenol-Explorer 3.0 is a peer-reviewed database paper describing the third major release of a freely accessible online resource cataloguing polyphenol content in foods and their known metabolites in humans, published in Nucleic Acids Research. The update extended the database to include data on gut microbial catabolism and human metabolism of polyphenols, substantially increasing its utility for nutritional epidemiology and dietary assessment research. It represents a systematic compilation of published analytical and metabolic data rather than a primary experimental study.
UK applicability
Phenol-Explorer is widely used by UK and European nutrition researchers and epidemiologists as a reference tool for estimating dietary polyphenol intake; its international food composition data can be applied to UK dietary studies, though some food items may reflect non-UK varieties or preparation methods.
Key measures
Polyphenol concentrations in foods (mg/100 g or mg/serving); number of compounds catalogued; metabolic pathways and metabolite identities; number of food items and publications indexed
Outcomes reported
The paper describes the expansion of the Phenol-Explorer database to version 3.0, reporting polyphenol content across hundreds of foods and incorporating data on polyphenol metabolism and catabolism in the human body. It documents the sources, concentrations, and metabolic fates of polyphenols derived from peer-reviewed literature.
