Abstract
The efficacy of a dietary intervention programme to control vitamin A deficiency through inexpensive, locally available sources of β-carotene was evaluated in 121 children 7–12 years old. The subjects were randomly divided into experimental and control groups. A three-day food intake was first recorded for each subject using a 24-hour recall method and repeated at the end of the study on a randomly selected subsample. The intervention period lasted one month, during which carrots, papayas, coriander, and mint were offered daily as sources of β-carotene. There was no significant difference in the dietary intakes of the groups before the study. After the intervention period, the serum vitamin A values of the experimental subjects were significantly higher than those of the controls. These results indicate that consumption of small amounts of inexpensive, readily available vegetable sources of β-carotene could help prevent and control vitamin A deficiency. Nutrition education programmes are needed to encourage the use of these foods for home consumption as well as in feeding programmes for schoolchildren.
