AIMS: The objectives of this study were to analyze retinol concentrations in two groups of bovine liver, to estimate the habitual consumption of bovine liver among pregnant women, and, based on these data, to evaluate the women's ingestion of vitamin A.METHOD: 60 samples of bovine liver, 30 of the Nelore breed and 30 of undefined breed (UB), were analyzed using the high-performance liquid chromatography (HPLC) method for retinol dosage. 100 women under care at the University Maternity Hospital Janu?rio Cicco, UFRN, in Natal, RN, Brazil, completed the Frequency of Nourishment Questionnaire.RESULTS: The mean +/- SD values for the retinol concentrations in the liver samples of the Nelore breed and the UB groups were 16,947.8 +/- 6,866.9 and 5,213.1 +/- 2,517.2 microg of retinol/100 g, respectively. A high number of women consumed liver (73%) and in 71% of the cases the advice for the consumption of this food was provided by qualified professionals.CONCLUSION: It is concluded that the daily consumption of the bovine liver is not recommended for pregnant women, regardless of the genetic origin of the animal.
