Exploring unconventional food plants used by local communities in a rural area of West Java, Indonesia: ethnobotanical assessment, use trends, and potential for improved nutrition.

Background: As one of the world's biodiversity hotspots, Indonesia contains over 25,000 plant species, including unconventional food plants (UFPs). These plants are integral to the dietary practices of rural communities, providing essential nutrients often overlooked in modern diets. However, the use of UFP is declining, with both their dietary and cultural values being undermined.
