Results of our study suggest that calculation of vitamin B-6 content of diets using a current database can provide a reasonably good estimation of the vitamin B-6 intakes of a population of lactating women. Our study also demonstrates that the mean vitamin B-6 intake of this group of lactating women 2 months after they had given birth, who were not using vitamin B-6 supplements, was 1.45 mg, which is less than 70% of the RDA. However, on the basis of guidelines for the assessment of vitamin B-6 status using dietary vitamin B-6:protein ratio (15,20), the women appeared to be consuming adequate amounts of vitamin B-6.
我们的研究结果表明，使用当前数据库计算饮食中的维生素B-6含量，可以对哺乳期妇女群体的维生素B-6摄入量提供较为准确的估计。我们的研究还表明，这群产后2个月且未使用维生素B-6补充剂的哺乳期妇女的平均维生素B-6摄入量为1.45毫克，低于推荐膳食摄入量（RDA）的70%。然而，根据使用膳食维生素B-6与蛋白质比例评估维生素B-6状况的指南（15,20），这些妇女似乎摄入了足够量的维生素B-6。
