| Background anr Aim: Beta-carotene is a precursor for retinol and is an antioxidant. This compound is used as natural color in food industries. In developing countries one of the best sources of retinol is carotenoids, especially for vulnerable groups (women, children, infants). Therefore the evaluation of bioavailability of this nutrient is very important.
Materials and Methods: In this cross-sectional study, 80 lactating mothers were selected from private and public hospitals in Tabriz. Demographic characteristics and dietary regimen of the patients were recorded after interview with the patients.
Colostrum beta-carotene was measured by means of Karr-Price method at 620nm and the concentration of beta-carotene was determined at the wavelength of 620nm.The dietary fiber were measured by use of Chen and Anderson method.
Results: The concentration of beta-carotene in milk and dietary intake was normal. The main source of vitamin A was from vegetables. Dietary fiber intake in comparison with recommended dietary allowance was high. There was no significant correlation between milk beta- carotene in well-nourished and undernourished mothers. There was also no significant correlation between dietary fat intake and colostrum beta-carotene of lactating mothers (p≤0/997) (r = 0/003).
Conclusion: Dietary fat when used with high amount of fibers has no significant effect on increasing the bioavailability of carotenoids. |
