title: Feeding of red palm oil-supplemented diets to rats may impact positively on vitamin A status.
abstract: The impact of feeding of dietary palm oil supplements on plasma vitamin A profile was investigated in animals. Four-week-old Wistar albino rats (n = 8 per group) were maintained for 28 days on standard rat food (4.7% fat by weight) supplemented (10%, 20% and 30% by weight) with red palm oil (RPO) and refined palm olein (REFPO). Plasma beta-carotene and vitamin A concentrations of rats fed RPO-based diets were higher than in rats fed REFPO and control diets. Animals fed 30% RPO-containing diets had lower plasma beta-carotene concentrations than those fed 20% RPO-containing diets. The results suggest that consumption of palm oil in moderate amounts enhances growth of tissues and bioavailability of beta-carotene, which may combat vitamin A deficiency in developing countries, in view of the fact that performed vitamin A in animal products (namely meat, liver, eggs and fatty fish) is out of the reach of economically deprived people.
