What type of dietary fiber includes pectin and can somewhat be digested?

The correct type of dietary fiber that includes pectin and can somewhat be digested is hemicellulose. Hemicellulose is a complex carbohydrate that, unlike insoluble fiber, has a structure that allows for partial fermentation by the bacteria in the human gut. This fermentability means that hemicellulose can provide some soluble fiber benefits, including the capacity to form gels, as seen with pectin.

In contrast, while insoluble fiber serves to add bulk to stool and aid in digestive movement, it is not fermented by gut bacteria and thus can't be digested. Cellulose, another form of insoluble fiber, is also resistant to digestion due to its structural properties. Lignin, which is technically not a carbohydrate but a complex organic polymer, is also indigestible and does not provide the same benefits as hemicellulose.
