vitamin status of infants in a free living population
A longitudinal study assessed the dietary adequacy and vitamin nutriture (for vitamins A, E, and ascorbic and folic acids) of 325 infants from birth to 3 years of age. Breast-fed infants generally had higher serum ascorbic acid and vitamin E levels than bottle-fed infants; however, the serum levels...

Summary: | A longitudinal study assessed the dietary adequacy and vitamin nutriture (for vitamins A, E, and ascorbic and folic acids) of 325 infants from birth to 3 years of age. Breast-fed infants generally had higher serum ascorbic acid and vitamin E levels than bottle-fed infants; however, the serum levels of folic acid were similar in both types of infants, while no infant had serum vitamin A levels less than 0.040 mg/dL. The proportion of infants having ascorbic acid intakes less than 80 per cent of the recommended intake decreased from 40 per cent (at age 6 months) to 10 per cent (at age 12 months) to 0 per cent (beyond 18 months), with vitamin A following a similar pattern. Most infants, however, had vitamin E (95 per cent) and folate (75 per cent) intakes that were less than 80 per cent of the recommended intakes. Infants supplemented with vitamin A and ascorbic acid had a higher nutritional status for these vitamins than unsupplemented infants. The study results suggest that vitamin supplements may be required for infants to ensure safe and adequate intakes.(wz) |
