The study examined the effect of food sources of beta-carotene, extra dietary fat, and parasitic intestinal
roundworms infection on blood vitamin A levels in children. Meals and snacks with various amounts of beta-carotene and fat were fed at midday to children 3-6 years of age for 3 weeks. Some groups of children were dewormed before the feeding period, whereas others remained infected.
roundworms infection on blood vitamin A levels in children. Meals and snacks with various amounts of beta-carotene and fat were fed at midday to children 3-6 years of age for 3 weeks. Some groups of children were dewormed before the feeding period, whereas others remained infected. The study found:
(a) The greatest rise in blood vitamin A levels occurred when meals contained added beta-carotene sources and added fat and the children were dewormed.
(b) Adding more fat to the meal and deworming the children caused a rise in blood vitamin A levels similar to that seen when feeding additional beta-carotene sources.
To conclude: Dietary fat enhances the uptake of beta-carotene and raises blood vitamin A levels.
