Summary
This narrative review synthesises evidence on how flavonoid compounds interact with food matrix constituents—lipids, proteins, carbohydrates and minerals—and how these interactions influence flavonoid bioaccessibility and bioavailability. The authors emphasise that flavonoids rarely exist in isolation in the diet and that the gut microbiome plays a crucial mediating role in their metabolism. The review highlights gaps in current understanding where individual flavonoid studies dominate literature despite the greater biological complexity of real food consumption patterns.
Regional applicability
The findings are relevant to UK dietary guidance and food industry reformulation, particularly for products fortified with or naturally rich in flavonoids (berries, tea, cocoa). The microbiome-flavonoid interaction data may inform personalised nutrition approaches in UK clinical and public health contexts, though further mechanistic work in UK populations is needed.
Key measures
Bioaccessibility of flavonoids; bioavailability of flavonoids; binding interactions (covalent and non-covalent); gut microbiome composition and function; nutrient absorption
Outcomes reported
The study examined how food matrix components (lipids, proteins, carbohydrates, minerals) interact with flavonoids to affect their bioaccessibility and bioavailability. It also evaluated the role of gut microbiota in flavonoid metabolism and bioavailability.
