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

摘要

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.
