Amorphophallus konjac: traditional uses, bioactive potential, and emerging health applications

Summary

Konjac is a plant used in Asian cuisine and traditional medicine for thousands of years that contains a special fiber called glucomannan. This fiber can help with weight loss, blood sugar control, and cholesterol reduction while also supporting a healthy gut and reducing inflammation. Modern research shows promising potential for using konjac to help prevent serious diseases like colorectal cancer and manage conditions like diabetes and inflammatory bowel disease.

Background

Amorphophallus konjac is a perennial plant native to Southeast Asia with a rich history in traditional Chinese medicine spanning over 2000 years. The plant’s primary bioactive component, konjac glucomannan (KGM), is a soluble dietary fiber with extensive applications in food and health industries.

Objective

This review aims to provide a comprehensive overview of the traditional uses, chemical and physical properties, and modern health applications of konjac glucomannan. It highlights cutting-edge research, discusses challenges and limitations, and identifies future directions for advancing KGM utility in health and nutrition.

Results

KGM demonstrates significant health benefits including weight management, blood glucose stabilization, lipid profile improvement, and gut health promotion. Evidence supports anti-inflammatory and immune-regulatory effects with applications in managing inflammatory bowel disease, hyperthyroidism, and colorectal cancer prevention.

Conclusion

KGM is a versatile dietary fiber with extensive applications in functional foods, nutraceuticals, and therapeutic interventions. Future research should focus on enhancing bioavailability, developing targeted delivery systems, and addressing challenges in purity and molecular consistency to optimize clinical outcomes.
