Non-covalent dietary fiber - Polyphenol interactions and their influence on polyphenol bioaccessibility

Jakobek, Lidija, Matić, Petra·2019·Trends in Food Science & Technology

Abstract

Abstract Background Polyphenolic compounds have shown many potentially positive bioactivities. But these beneficial effects depend on the amount of polyphenols accessible for absorption in the upper or lower parts of the digestive tract (bioaccessibility) or on the amount actually absorbed. Dietary fibers can interact with polyphenols in the digestive tract creating associations with them, which might influence polyphenol bioaccessibility in the digestive tract and therefore their bioactivities. Scope and approach The aim of this review is to discuss recent literature about non-covalent dietary fiber - polyphenol interactions, the parameters that affect these interactions, the types of bonds between polyphenols and dietary fibers and the influence of dietary fibers on the polyphenol bioaccessibility in the upper and lower parts of the digestive tract. Key findings and conclusions Dietary fibers create associations with polyphenols. This process depends on environmental conditions like pH value, temperature and ionic strength. In both, the upper and lower parts of the digestive tract, polyphenols can be released from various food matrices. Dietary fibers affect that process by lowering the polyphenol amount released in the upper digestive tract. By this mechanism, they also potentially increase the polyphenol amount that reaches lower parts of the digestive tract, where polyphenols, once released, can show beneficial effects. Dietary fibers might be a sort of a “control mechanism” for controlling the amount of bioaccessible polyphenols in the upper or lower parts of the digestive tract. Further studies are needed to clarify the role of dietary fibers in polyphenol bioactivities.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
