Crude fiber is the old name of dietary fiber, and it is the main component of plant cell wall, including cellulose, hemicellulose, lignin and keratin.

Eating some foods containing crude fiber can promote gastrointestinal movement and help digestion to a certain extent, which is beneficial. However, crude fiber can also prevent digestive enzymes in the digestive tract from contacting chyme, thus reducing the digestibility of nutrients. In addition, crude fiber can also hinder the intestinal tract from absorbing some small molecular nutrients.
