Abstract

Objective: To determine the effect of a biscuit with red palm oil as a source of beta -carotene on the vitamin A status of primary school children and to compare this with the effect of a biscuit with beta -carotene from a synthetic source. Design: Randomised controlled trial. Setting: A rural community in KwaZulu-Natal, South Africa. Subjects: A total of 437 primary school children, aged 5-11 y; 400 completed the study. Intervention: Subjects were randomly assigned to one of three groups, receiving, respectively: (i) a placebo biscuit; (ii) a biscuit with synthetic beta -carotene as a vitamin A fortificant (SB); (iii) a biscuit with red palm oil as a source of beta -carotene (PB); SB and PB supplied 30% of the RDAfor vitamin A per serving of three biscuits. Biscuits were distributed daily during the school week; vitamin A status was assessed at baseline and after 3 months. Results: There was a significant improvement in serum retinol compared to the control group in both the SB and PB groups (P < 0.005); the treatment effect for the two groups was equivalent (difference in treatment effect 0.62 mug/dl, with a 90% CI -0.33 -1.57). Conclusions: A biscuit with red palm oil as a source of beta -carotene is as effective as a biscuit with synthetic beta -carotene in improving the vitamin A status of primary school children. The additional qualities of red palm oil (ie no trans fatty acids; rich source of antioxidants) make it an excellent alternative fortificant for addressing vitamin A deficiency.
