Dietary fiber composition for targeted improving of metabolism syndromes

The invention belongs to the technical field of food science, and particularly relates to a dietary fiber composition for targeted improving of metabolism syndromes. According to the dietary fiber composition, xylan and mannan are used as basic components, and an appropriate amount of levan, an appropriate amount of pectin, and an appropriate amount of cellulose are added, so that the dietary fiber composition is prepared. The dietary fiber composition comprises the following components of xylan, mannan, levan, pectin and cellulose, wherein the weight ratio of the xylan to the mannan to the levan to the pectin to the cellulose is (5-90) to (5-90) to (5-90) to (0.01 to 70) to (0.01-70). The prepared dietary fiber composition can effectively improve various symptoms of metabolism syndromes,and can delay the disease processes. The dietary fiber composition is clear in action mechanisms, and clear in target treatment for diseases. The dietary fiber composition can clearly show clear and positive effects on many r
