Meanings of nondigestible carbohydrates in English

SCFAs are primarily produced in the colon by bacterial fermentation of nondigestible carbohydrates.

Prebiotics are nondigestible carbohydrates that alter gut microbiota and could potentially improve glycemic control and reduce intestinal permeability and thereby insulin sensitivity.

Importance: Fermentation of dietary nondigestible carbohydrates by the human colonic microbiota supplies much of the energy that supports microbial growth in the intestine.
