Summary
This review by Gary Williamson, a leading authority on dietary polyphenols, synthesises current knowledge on the bioavailability of food-derived polyphenols in humans, encompassing their absorption, metabolism, and biological fate. The paper likely addresses key determinants of bioavailability including chemical structure, food matrix interactions, colonic microbial transformation, and inter-individual variation. Published in the Annual Review of Food Science and Technology, it is likely to serve as a comprehensive reference point for researchers working at the intersection of food composition, nutrition, and human health.
UK applicability
The findings are broadly applicable to UK dietary and public health contexts, including potential relevance to UK dietary guidelines and reformulation strategies, given that polyphenol-rich foods such as fruits, vegetables, tea, and whole grains feature prominently in UK diets. Williamson is based at a UK institution, and his work has previously informed UK and European nutritional research agendas.
Key measures
Polyphenol absorption rates; urinary and plasma metabolite concentrations; gut microbiota metabolite profiles; food matrix effects on bioavailability
Outcomes reported
The review examines the extent to which polyphenols from food are absorbed, metabolised, and utilised in the human body, likely covering factors influencing bioavailability such as food matrix effects, gut microbiota, and chemical structure. It likely synthesises current evidence on plasma and urinary metabolite profiles as proxies for bioavailability.
