Fibers are Polysaccharides
Dietary fiber be fulfilling the role of the structural part of plants and therefore are in all foods from plant products such as vegetables, fruits, cereals and legumes. Most fibers are considered, chemically as polysaccharides, but not all fibers are polysaccharides (eg starch is a vegetable fiber). The fibers are described as non-starch polysaccharides (non-starch polysaccharides). Some constituents of the fibers are cellulose, Hemicellulose, Pectins, Gums and Mucilages. The fibers may also include some non-polysaccharide compounds such as lignin (are polymers of several dozen phenol alcohol molecules with strong internal organic make them impervious to digestive enzymes), the Cutin and tannins. As has been investigating the fiber incorporated other chemicals to the list.
Fiber-Rich Foods Preventing Constipation
Adopt a diet rich in fiber. The plant foods – fruits, vegetables, legumes, whole grains, nuts and seeds, seaweed – all contain fiber, while those of animal origin do not. There are two types of fiber: insoluble and soluble fiber. Generally, plants contain both types of fibers, with dominance for the insoluble fiber. Some only contain soluble fiber in large quantity.
The cellulose, Hemicellulose and Lignin are insoluble. They prevent constipation by absorbing much water, which stimulates contractions of the intestine. Must accompany the consumption of these fibers plenty of fluids to avoid obstruction of the digestive tract.
Pectin, gums and mucilages are soluble fibers. Psyllium is one of the few plants to contain mostly soluble fiber. Oats and barley also contain. This type of fiber helps prevent constipation by absorbing water and creating a gel. They also help control blood sugar and lower cholesterol.
Recall that according to the Food Guide, we should consume 6 to 8 servings of grain products per day, preferably whole grain or enriched.
