One reason is that it enhances gut motility by providing the gut walls substance to "hold onto" and prevent constipation.
as an example: fiber, chitin
Dietary fiber, for humans, is indigestible. Any indigestible materials are excreted out of the body, and fiber is no exception.
Cellulose (plant fiber)
yes any fruit does because it contain indigestible fiber which helps push things through your digestive system, but there are things that have much more fiber than grapes.
Fiber
Indigestible materials are substances that cannot be broken down by the digestive system and therefore cannot be absorbed by the body. These materials pass through the digestive tract unchanged and are eventually eliminated in the stool. Some examples include fiber and certain types of plant materials.
Indigestible material is primarily made up of insoluble fiber. This plant materials adds bulk to the feces.
It's indigestible, so yes.
Dietary fiber is any indigestible sugar polymer (e.g. cellulose, pectin, chitin, inulin, oligosaccharide) or other any similar indigestible plant polymer (e.g. lignin).
Indigestible food refers to substances in our diet that cannot be broken down or absorbed by our digestive system. These include fiber, cellulose, and certain types of sugars that pass through the gastrointestinal tract largely unchanged and provide benefits like promoting bowel regularity. Consumption of indigestible food can help with digestion and overall gut health.
Some examples of things that are generally considered indigestible by humans include cellulose (a complex carbohydrate found in plant cell walls), certain types of fibers (such as insoluble fibers), and certain parts of animals that are difficult to break down (such as bones and cartilage). Additionally, some substances like plastic or metals are not meant to be ingested and are indigestible by the human digestive system.
