Fiber is a virtually indigestible substance that is found mainly in plants and vegetables. Fiber is a special type of carbohydrate that passes through the human digestive system virtually unchanged, without being broken down into nutrients.
Fiber is important because it has an influence on the digestive process from start to finish:
- Fiber supports regularity and aids in digestive health.
- Fiber slows digestion and absorption so that glucose (sugar) in food enters the bloodstream more slowly, which keeps blood sugar on a more even level.
- Fiber is broken down in the colon (the main part of the large intestine) by bacteria and the simple organic acids produced by this breakdown helps to nourish the lining of the colon.
