Wheat bran has a high content of dietary fiber. Food sources of dietary fiber have traditionally been divided according to whether they provide how to make fruit jelly dessert or insoluble fiber. Plant foods contain both types of fiber in varying amounts, according to the fiber characteristics of viscosity and fermentability.
Examples are wheat bran, cellulose, and lignin. Coarsely ground insoluble fiber triggers the secretion of mucus in the large intestine, providing bulking. Dietary fiber is defined to be plant components that are not broken down by human digestive enzymes. Dietary fiber consists of nondigestible carbohydrates and lignin that are intrinsic and intact in plants.
Added Fiber” consists of isolated, nondigestible carbohydrates that have beneficial physiological effects in humans. Dietary fiber is the edible parts of plants or analogous carbohydrates that are resistant to digestion and absorption in the human small intestine, with complete or partial fermentation in the large intestine. Dietary fiber includes polysaccharides, oligosaccharides, lignin, and associated plant substances. Dietary fiber means carbohydrate polymers with more than 10 monomeric units, which are not hydrolyzed by digestive enzymes in the small intestine of humans. Dietary fibre refers to a group of substances in plant foods which cannot be completely broken down by human digestive enzymes. This includes waxes, lignin and polysaccharides such as cellulose and pectin. Originally it was thought that dietary fibre was completely indigestible and did not provide any energy.
It is now known that some fibre can be fermented in the large intestine by gut bacteria, producing short chain fatty acids and gases. Fibre means carbohydrate polymers with three or more monomeric units, which are neither digested nor absorbed in the human small intestine. Dietary fibers can act by changing the nature of the contents of the gastrointestinal tract and by changing how other nutrients and chemicals are absorbed. Some types of soluble fiber absorb water to become a gelatinous, viscous substance.
