Polydextrose is a water-soluble dietary fiber renowned for its favorable physicochemical properties and physiological benefits. It is widely incorporated into a broad range of food products, particularly those designed to be low in calories, sugar, and fat.

Key Health Benefits & Physiological Functions

1. Lipid Metabolism Regulation
   Polydextrose forms a gel-like membrane in the small intestine, which can encapsulate dietary fats. This action effectively limits fat absorption, promotes the excretion of lipids, increases feelings of fullness, and reduces subsequent food intake. Consequently, it aids in regulating blood lipids, reducing fat accumulation, and helping to prevent obesity.

2. Cholesterol Reduction
   It acts by adsorbing bile acids and cholesterol in the digestive tract. This process inhibits the rise in total cholesterol (TC) levels, reduces the synthesis and reabsorption of bile salts, and ultimately helps lower both plasma and liver cholesterol concentrations. This mechanism supports the prevention and management of conditions like coronary artery sclerosis, gallstones, and cardiovascular diseases.

3. Moderation of Sugar Absorption
   By creating a physical barrier, polydextrose limits the contact between food and digestive enzymes. This suppresses the secretion of glucagon, slows down glucose absorption, and helps lower postprandial blood sugar levels, thereby maximizing insulin efficiency and contributing to diabetes prevention.

4. Relief and Prevention of Constipation
   Polydextrose absorbs and retains water within the intestines, which increases stool bulk, softens it, and stimulates intestinal peristalsis. This leads to more frequent bowel movements and effectively promotes regularity, helping to prevent and alleviate constipation.

5. Detoxification and Skin Health
   It helps regulate intestinal pH, creating a favorable environment for the growth of beneficial bacteria such as Bifidobacteria. By promoting a healthy gut microbiome and inhibiting the growth of harmful saprophytic bacteria, it helps prevent intestinal mucosal atrophy. The subsequent timely excretion of toxins and metabolic wastes prevents their potential expulsion through the skin, thereby supporting skin health and contributing to the prevention of conditions like hemorrhoids, gastroenteritis, and colon cancer.

Through these multifaceted mechanisms, polydextrose serves as a valuable functional ingredient for developing healthier food products that support weight management, metabolic health, digestive wellness, and overall detoxification.
