Question

explain and summarize the information regarding Dietary fiber.. in terms of its physicochemical, structural and functional properties

Answer 1

Dietary fiber, also known as fiber, is the indigestible part of plant foods. Fiber has many health benefits, including reducing the risk of heart disease and type 2 diabetes. Fiber is mainly found in vegetables, fruits, whole grains and legumes.

Dietary fiber is a ubiquitous component in plant foods, including materials with a variety of chemical and morphological structures. Dietary fiber has been recognized as having considerable health benefits, and there is evidence that low intake may be related to many diseases. Dietary fiber is a polymer matrix with variable physical and chemical properties, including sensitivity to bacterial fermentation, water retention capacity, cation exchange and adsorption functions. These characteristics determine the physiological effects. Due to the enzymatic action of bacteria in the colon, fiber composition changes. Dietary fiber is of clinical importance in certain colonic dysfunctions and glucose and lipid metabolism. Determining the physical and chemical properties of fiber and the evolution of these properties in the process of passing through the gastrointestinal tract is of great significance for predicting the effects and effects of various dietary fibers on human health.
