What is dietary fiber?
Dietary fiber is a polysaccharide that can neither be digested and absorbed by the gastrointestinal tract nor produce energy. It is considered non-nutritional.

Classification of dietary fiber
Dietary fiber is divided into soluble dietary fiber and insoluble dietary fiber.
Most plant foods contain both types of dietary fiber.
Soluble dietary fiber mainly comes from pectin, algae, konjac, etc., swells after absorbing water, making the bolus thick, soluble fiber is intertwined with carbohydrates such as starch in the gastrointestinal tract, and delays the absorption of the latter. Therefore, it can play a role in reducing postprandial blood glucose;
The best sources of insoluble dietary fiber are whole grains, including wheat
bran, oatmeal, whole wheat flour and brown rice, oat whole grains, beans, vegetables, and fruits. The effect of insoluble fiber on the human body lies in
promoting the peristalsis of the gastrointestinal tract, accelerating the passage of food through the gastrointestinal tract, and reducing absorption. In addition,
the insoluble fiber absorbs water in the large intestine to soften stool, which
can prevent and treat constipation.
