Answer:
True
Explanation:
Dietary fiber consists of nondigestible carbohydrates and lignin that are intrinsic and intact in plants. 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.
Many natural products as foods contain a great number of polysaccharides that cannot be completely digested by our digestive system. These indigestible polysaccharides are often called dietary fiber. The typical dietary fiber includes cellulose, hemicellulose, β-glucan, pectin, mucilage, gums and lignin.
To get all those benefits, there are two types of fiber that your body needs: soluble and insoluble. Both come from plants and are forms of carbohydrates. But unlike other carbs, fiber can't be broken down and absorbed by your digestive system.
Dietary fiber, also known as roughage, is the indigestible part of plant foods. Fiber has a host of health benefits, including reducing the risk of heart disease and type 2 diabetes.
