Preliminary Research on the Probiotic Effects of Konjac Glucomannan and Its Improvement on Lactose Intolerance

Preliminary Research on the Probiotic Effects of Konjac Glucomannan
and Its Improvement on Lactose Intolerance
 

    Lactose intolerance, caused by a deficiency of the enzyme lactase in the small intestine, results in the fermentation of lactose in the colon, leading to discomfort. Research suggests that bacterial metabolism in the colon may be the key to managing this condition. Konjac glucomannan (KGM) and its oligosaccharide form (KOGM), both natural prebiotics, can improve gut health by promoting the growth of beneficial bacteria such as *Bifidobacteria* and *Lactobacilli*, which are capable of producing lactase. This creates a beneficial microbiome cycle that may help alleviate symptoms of lactose intolerance. This study explores the fermentation characteristics of KGM and KOGM in a simulated human gut environment, aiming to verify their potential probiotic effects for individuals with lactose intolerance.

 1. Physiological Activity of KGM and KOGM: Research Progress

 

    KGM, due to its unique molecular structure, has a range of physical and chemical properties, including water absorption, gelation, film formation, and thickening. It has also been found to alleviate constipation, reduce body weight, lower blood pressure and blood sugar, and even reduce cancer risk, making it a valuable resource in food, medicine, and chemical industries. As a prebiotic, KGM promotes the growth of beneficial gut bacteria like *Bifidobacteria* and *Lactobacilli*, which are essential for gut health. KOGM, a functional oligosaccharide, similarly encourages the proliferation of beneficial bacteria, alters the structure of the gut microbiota, and inhibits the growth of harmful bacteria. Regarding lactose intolerance, KGM and KOGM stimulate the growth of *Bifidobacteria*, which enhances lactase secretion. This promotes a "lactase-oligogalactose-bifidobacteria" microbiome cycle that helps alleviate lactose intolerance symptoms and maintains a healthy gut microbiome.

2. The Role of KGM in Reducing Symptoms of Lactose Intolerance

 

    Bifidobacteria are known for their high activity of β-galactosidase, an enzyme that effectively breaks down lactose into glucose and galactose, preventing the symptoms of lactose intolerance. KGM and KOGM act as functional ingredients that selectively stimulate the growth of beneficial bacteria like *Bifidobacteria*, promoting the production of short-chain fatty acids (SCFAs) and maintaining the balance of the gut microbiota. This balance is crucial for mitigating lactose intolerance symptoms. In lactose intolerance, colonic bacteria play a key role. When undigested lactose enters the colon, it is fermented by bacteria, producing SCFAs and gases, both of which are closely associated with the severity of lactose intolerance symptoms. The efficiency with which the colon clears these fermentation products also influences the severity of the symptoms. Prebiotics like KGM and KOGM modify the gut microbiota, promoting the growth of beneficial bacteria and regulating colonic metabolism to alleviate lactose intolerance symptoms.

 3. Future Prospects

 

    Lactose intolerance is a global health issue, affecting both children and adults. In children, it can hinder growth and development, while in adults, it may lead to osteoporosis and digestive discomfort. KGM and KOGM, as natural and safe food ingredients, offer various health benefits, such as relieving constipation, reducing weight, and preventing diabetes and cancer. They have also been found to function as prebiotics, stimulating the growth of beneficial bacteria like *Bifidobacteria* and *Lactobacilli* and promoting the production of SCFAs. This process helps establish the "lactase-oligogalactose-bifidobacteria" microbiome cycle, which maintains gut balance and theoretically improves symptoms of lactose intolerance.

Given the limited research on prebiotics for treating lactose intolerance, future studies will focus on in-vitro fermentation experiments, animal studies, and mouse models to explore the potential of KGM and KOGM in improving lactose intolerance. These studies aim to provide a theoretical foundation and practical application guidance for developing new prebiotic products, offering a promising treatment pathway for lactose intolerance and providing relief to those affected.
