The chemical composition of human milk obtained from 16 underweight women and 25 controls collected at four, eight and 12 weeks of lactation, was determined in order to assess the effect of maternal nutrition upon milk quality. No meaningful differences were observed for protein, lactose, energy, calcium, iron and copper contents. The values obtained are comparable to those reported in the literature from developed countries. As to Zn content, both groups exhibited decreased values with time, with significant higher values for the controls at the 12th week of observation. Magnesium showed exactly the opposite behavior. On the basis of the present study, it is concluded that maternal nutrition does not condition important changes in the chemical composition of human milk. The authors propose the application of comparable methodologic and analytical criteria, in order to achieve a more complete understanding of the relationships between maternal nutrition and lactation.
为评估母体营养对乳汁质量的影响，对16名体重不足的女性和25名对照者在哺乳期第4周、第8周和第12周采集的母乳的化学成分进行了测定。在蛋白质、乳糖、能量、钙、铁和铜含量方面未观察到有意义的差异。所获得的值与发达国家文献报道的值相当。至于锌含量，两组的值均随时间下降，在观察的第12周，对照组的值显著更高。镁的情况则恰恰相反。根据本研究得出结论，母体营养不会导致母乳化学成分发生重要变化。作者建议应用可比的方法学和分析标准，以更全面地了解母体营养与哺乳之间的关系。
