Dietary fiber - Wikipedia
Dietary fibers are diverse in chemical composition and can be grouped generally by their solubility, viscosity and fermentability which affect how fibers are processed in the body. [2] Dietary fiber has two main subtypes: soluble fiber and insoluble fiber which are components of plant-based foods such as legumes , whole grains , cereals ...
