Cassava (Manihot esculenta), water convolvulus (Ipomea reptans) and brassica (Brassica juncea L) leaves, carrot (Daucus carrota L), and sweet potato (Ipomea batata) were cooked imitating local household preparation while banana (Musa paradisiaca L) was freeze-dried. The prepared foods, each containing 180 g -carotene, were fed to vitamin A-depleted rats in addition to their vitamin A-depleted diet for 14 days. The positive control group received 13 g retinol daily. After repletion, plasma retinol in treated groups increased slightly ranging from 0.03 to 0.34 g/ml. The groups received boiled cassava leaves, boiled and simmered cassava leaves, boiled or simmered water convolvulus, boiled or simmered brassica, boiled carrots, boiled or fried sweet potatoes, or freeze-dried banana and accumulated retinol levels of,
