This study, which investigated consumption patterns of leafy vegetables in Nigeria, showed low levels of intake. ‘Ugwu’ was most preferred over other vegetables, including celosia, waterleaf, amaranthus, and okra leaf. Only 35.4% of respondents reported proper handling and preparing of vegetables, and only 9.1% of respondents adopted the most appropriate method of preparing and handling of vegetables for maximum absorption of nutrients.
