Objective: We aimed to quantify the efficacy of provitamin A¿rich vegetables and fruit in improving vitamin A status. Design: Breastfeeding women in 9 rural communes in Vietnam were randomly allocated to 1 of 4 groups: the vegetable group (n = 73), which ingested 5.6 mg ß-carotene/d from green leafy vegetables; the fruit group (n = 69), which ingested 4.8 mg ß-carotene/d from orange or yellow fruit; the retinol-rich group (n = 70), which ingested 610 µg retinol/d from animal foods and 0.6 mg ß-carotene/d; and the control group (n = 68), which ingested 0.4 mg ß-carotene/d. Meals of groups 1, 2, and 4 contained
