[Glucomannan: properties and therapeutic applications].

Area of Science:

• Dietary Fiber Research
• Plant Polysaccharides
• Human Health and Nutrition

Background:

• Glucomannan is a soluble dietary fiber derived from Amorphophallus konjac tubers, used traditionally in East Asia and increasingly in Western countries.
• Its chemical structure comprises mannose and glucose units linked by beta (1-->4) glycosidic bonds, resulting in high molecular weight and viscosity.
• This fiber exhibits exceptional water-holding capacity, forming highly viscous solutions.

Purpose of the Study:

• To review the characteristics, properties, physiological effects, and therapeutic applications of glucomannan.
• To highlight glucomannan's role in human health and its traditional and contemporary uses.
• To provide a comprehensive overview of glucomannan's benefits and drawbacks.

Main Methods:

• Literature review of scientific studies on glucomannan.
• Analysis of glucomannan's chemical structure and physical properties.
• Examination of physiological effects and therapeutic uses reported in existing research.

Main Results:

• Glucomannan demonstrates efficacy in obesity treatment via satiety, constipation relief by increasing fecal volume, and potential cholesterol and glucose level reduction.
• Its high viscosity and water-binding capacity contribute to its physiological effects.
• Potential adverse effects include flatulence, abdominal pain, and gastrointestinal or esophageal obstruction, alongside possible drug bioavailability interactions.

Conclusions:

• Glucomannan possesses significant therapeutic potential for various health conditions, supported by its unique physicochemical properties.
• Understanding both the benefits and adverse effects is crucial for its safe and effective application.
• Further research may elucidate optimal usage and mitigate potential risks associated with glucomannan consumption.
