Summary
This narrative review by Gary Williamson, published in Nutrition Bulletin in 2017, synthesises evidence on the dietary role of polyphenols — a broad class of plant-derived compounds found in fruits, vegetables, tea, coffee, and wholegrains. The paper likely covers classification, food sources, gut metabolism, and the evidence base linking polyphenol consumption to reduced risk of chronic non-communicable diseases. It is aimed at a practitioner and policy audience given the journal's profile, and provides an accessible overview of a complex and evolving field.
UK applicability
The review is internationally relevant but published in a UK-based nutrition journal and likely references dietary intake data pertinent to UK and European populations; its findings are applicable to UK dietary guidelines and public health nutrition policy.
Key measures
Polyphenol intake estimates (mg/day); bioavailability and metabolic pathways; disease risk associations from epidemiological and intervention studies
Outcomes reported
The review examines the dietary intake of polyphenols from plant-based foods, their bioavailability and metabolism, and their associations with health outcomes including cardiovascular disease, type 2 diabetes, and cognitive function.
