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.
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 Januário Cicco, UFRN, in Natal, RN, Brazil, completed the Frequency of Nourishment Questionnaire.
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.
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. The study alert health professionals of the danger of recommending the ingestion of bovine liver during pregnancy.
本研究的目的是分析两组牛肝中的视黄醇浓度,估计孕妇中牛肝的习惯性摄入量,并基于这些数据评估女性维生素A的摄入量。
采用高效液相色谱(HPLC)法测定视黄醇剂量,分析60份牛肝样本,其中30份为内罗尔品种,30份为未定义品种(UB)。100名在巴西RN纳塔尔市UFRN的雅努ário Cicco大学妇产医院接受护理的女性完成了营养频率问卷。
内罗尔品种和未定义品种组肝脏样本中视黄醇浓度的平均值±标准差分别为16,947.8±6,866.9和5,213.1±2,517.2微克视黄醇/100克。大量女性食用肝脏(73%),71%的情况下,食用这种食物的建议由合格的专业人员提供。
得出的结论是,无论动物的遗传来源如何,均不建议孕妇每日食用牛肝。该研究提醒健康专业人员注意在怀孕期间推荐摄入牛肝的危险性。
