How Fiber Works Inside the Digestive System: A Step-by-Step Explanation

The digestion of fiber is a complex series of events that begins in the mouth and continues into the large intestine. In this section, we explain in detail how fiber works within the digestive system.

The Journey of Fiber from the Mouth to the Stomach

The journey of fiber begins in the mouth, where food is chewed and mixed with saliva. Although saliva contains digestive enzymes, it does not contain enzymes specifically for fiber digestion. The food mixture then moves to the esophagus and into the stomach.

In the stomach, fiber is mixed with digestive juices containing hydrochloric acid and pepsin. However, fiber is not significantly digested in the stomach because digestive enzymes cannot break it down.

The Effect of Fiber in the Small Intestine

Fiber then moves to the small intestine, where many nutrients are absorbed. Some types of soluble fiber form a gel around food, slowing digestion and helping improve the absorption of nutrients.

The Role of Fiber in the Large Intestine

Fiber reaches the large intestine, where it plays an important role in feeding beneficial gut bacteria and undergoing fermentation. This fermentation produces short-chain fatty acids, which provide energy to intestinal cells.

Fermentation of Fiber and Production of Short-Chain Fatty Acids

Fermentation of fiber in the large intestine produces three main types of short-chain fatty acids: acetate, propionate, and butyrate. These acids play a key role in maintaining intestinal health and supplying energy to the body.
