Resumen
The world is facing the global challenges of insecurity, poverty and climate change, which can impede food availability, production and nutritional security. Due to these factors, the production and availability of crop species such as legumes, pulses and cereals are declining, while some are gradually becoming extinct, which affects consumption. To meet global food demands, efforts should be geared towards promoting the cultivation and utilization of underexploited and neglected crops, which have the potential to improve food and nutrition security. However, the exploitation and utilization of crops mostly depend on existing knowledge. Therefore, this review gives an overview of the current knowledge regarding lima beans (Phaseolus lunatus L.), an underutilized legume that can serve as a promising potential food crop. While there are some studies on lima beans, they cannot compare to the abundance of studies on other legumes. It is essential to exploit the nutritional and health properties of this crop, as well as to explore processing techniques such as cooking, soaking, fermentation and germination for transforming them into other food forms. Despite the dearth of information on this crop compared to other legumes, there is a case for the promotion of lima beans, especially where there are incessant food shortages, as they will allow for dietary diversity. This is vital considering the vulnerability of world food systems, coupled with an ever-growing population, necessitating a focus on other neglected crops to improve food security.
