Summary
This narrative review, published in Molecular Nutrition & Food Research, synthesises recent advances in understanding the bioavailability of dietary carotenoids including beta-carotene, lycopene, lutein, and zeaxanthin. It examines how food matrix composition, processing methods, and host physiological factors modulate carotenoid absorption and conversion to provitamin A. The paper provides an updated framework for interpreting carotenoid bioavailability data relevant to nutritional research and dietary guidance.
UK applicability
Although not UK-specific, the findings are broadly applicable to UK dietary assessment and public health nutrition, particularly in relation to fruit and vegetable consumption recommendations and the role of food preparation in optimising micronutrient intake.
Key measures
Carotenoid absorption and bioavailability indicators (e.g. plasma carotenoid concentrations, bioaccessibility from in vitro digestion models, relative bioavailability estimates)
Outcomes reported
The paper reviews determinants of carotenoid bioavailability including food matrix effects, processing, co-ingested nutrients, and host-related factors. It likely reports on absorption efficiency metrics and the influence of dietary fat, fibre, and cooking on carotenoid bioaccessibility.
