Consumo de vitamina A e contribuição de retinol e carotenoides para a dieta de lactantes

Abstract

Objectives: The study aimed at investigating the intake of vitamin A for lactating women, highlighting the contribution of the food sources of vitamin animal A (retinol) and vegetable (carotenoids) to the diet of the target population. Methods: This study is observational and descriptive. The sample consisted of lactating womenof 18-40 years of age, being held the application of socioeconomic questionnaire and 24-hour recalls during the postpartum 1 week, 1 month and 3 months for obtaining the usual daily consumption of lactating . They were also collected data on the latest prenatal care. dietary contribution of retinol and carotenoids through quantitative analysis of the consumption of these nutrients has been verified. Results: The study included 152 infants. The usual daily intake of vitamin A of lactating women was 825.79 ug, which is obtained mainly by the consumption of food contribution of carotenoid plant (78.58%). It was observed that 59.9% of participants obtained a vitamin A consumption considered insufficient, resulting in low-risk, moderate and high vitamin A deficiency (VAD) to respectively 0.7% (n = 1), 36.2 % (n = 55) and 23% (n = 35) of lactating. Conclusions: Breastfeeding showed an insufficient intake of vitamin A, with a high prevalence of risk for VAD, the highest prevalence rates of contribution was derived carotenoid foods of plant origin, which is less efficient absorption and bioavailability. From this perspective, can be proposed intervention actions to promote the improvement of dietary intake of vitamin sources A.
