This invention discloses the application of a composition in the preparation of foods or medicines that reduce blood lead levels, belonging to the field of food or pharmaceutical applications. The composition is for improving intestinal
microecology, comprising
inulin, galactooligosaccharides,
polydextrose, and water-
insoluble dietary fiber, wherein the weight ratio of
inulin, galactooligosaccharides,
polydextrose, and water-
insoluble dietary fiber is 25:25:20:30, and the composition is taken immediately after being dissolved in
warm water before meals. This invention, through the rational combination of water-
insoluble dietary fiber and functional polysaccharides, adjusts the release rate of nutrients in the intestine, slows down
digestion, absorbs and eliminates toxic substances from food, reduces
intestinal permeability, and simultaneously possesses the functions of water absorption and swelling, gradient adhesion, mechanical isolation, mesh adsorption,
ion exchange, and microbial regulation, providing a favorable environment and food for the growth of
intestinal microorganisms, and effectively reducing blood endotoxins and blood lead levels, enhancing
immunity, and preventing chronic diseases.
