Nutraceutical potential of underutilized tuber crops: Pharmacological insights and applications

Underutilized tuber crops represent a significant reservoir of nutraceutical potential, offering diverse phytochemicals with promising pharmacological properties.This review examines the nutritional profile, bioactive components, and health benefits of a number of underutilized tubers including West Indian arrowroot, Chinese yam, yam bean, Dioscorea and edible canna.We highlight their roles in addressing global health challenges, including obesity, diabetes, and cardiovascular diseases.Additionally, we also go over the mechanism of their bioactive components such as antioxidants, anti-inflammatory agents and antimicrobial properties.The findings underscore the need for increased awareness and integration of these crops into diets and agricultural practices, promoting sustainable food systems while unlocking their full therapeutic potential.Future research directions are proposed to investigate the pharmacological applications of these crops further, paving the way for novel health interventions.
