Detailed explanation-3: -[1] Some types of fiber fall into both categories, such as oligosaccharides and resistant starches that may be naturally occurring or synthetically made. Naturally occurring plant fibers: Cellulose, hemicellulose – Insoluble fiber found in cereal grains and the cell walls of many fruits and vegetables.

Detailed explanation-4: -Sources of Fibers The most common fibers are from the exterior husk of cereals and grains, which contain the insoluble fibers cellulose and lignin. Both cellulose and lignin are main components of most plants and can be found in the tough, fibrous materials of plant-based products.
