Objective: To conduct a systematic review of the Vitamin “A” food consumption by pregnant women in Brazil. Methods: The review consisted of a search for articles published in the period from 1999 to 2015 in SciELO, PubMed, and LILACS databases. At the end, eight articles were selected for this review. Results: The methods used for the analysis of the intake of vitamin “A” were: food frequency questionnaire (FFQ) – considering the diet or only vitamin “A” foods and the dietary recall (24hDR). Only two articles estimated the adequacy of the Vitamin “A” food consumption by the population assessed. Some methodological limitations were quite frequent, emphasizing the lack and/or limitation of information on the sample representativeness, loss of studies, accuracy of the methods applied and the control of confounding variables. Conclusion: It is observed that there are still few studies that critically assess the Vitamin “A” food consumption by pregnant women in Brazil, and that the identification and control of possible biases of the dietary surveys can improve the reliability of the information found.
