个性化膳食指导对壮族乳母膳食结构及乳汁钙铁锌含量影响的分析

Influence of Individual Diet Instruction on Thelastria Diettary Pattern and Calcium Iron Zinc Contents in Breast Milk in Zhuang Population

目的探讨个性化膳食指导对乳母膳食结构和乳汁中钙、铁、锌含量的影响。方法将南宁市100例壮族乳母随机分为对照组和实验组,每组50例,实验组接受个性化膳食指导,对照组给予普通膳食指导,于干预前后调查两组膳食结构,测定乳汁中钙、铁、锌含量。结果两组乳母干预前膳食结构不均衡;干预后,对照组水果及奶类摄入量增加,其余膳食种类摄入量无明显变化;实验组禽肉类摄入量明显降低,除粮谷类、奶类和大豆坚果外,其余均达哺乳期妇女平衡膳食宝塔推荐值;对照组乳汁中锌含量增加,但钙、铁含量无明显变化;实验组乳汁中钙、锌含量增加,铁含量无明显变化。结论通过个性化膳食指导,可以改善乳母的膳食结构,增加营养素及矿物质的摄入量,提高乳汁中钙、锌的含量,但铁含量无明显变化。

Objective To study the effect of individual diet instruction on thelastria dietary pattern and calcium , iron,zinc contents in breast milk .Methods One hundred lactating women of Zhuang nationality in Nanning City were randomly divided into control group and experimental group ,50 cases in each group .The experimental group received the individual diet instruction while the control group received the ordinary diet instruction .To investigate the dietary patterns in two groups before and after intervention .The calcium,iron,zinc contents in breast milk were detected .Results The dietary patterns of lactating women showed an imbalance in both groups.After intervention,the intakes of fruit and milk increased in the control group,but the rest intakes showed no significant changes.The poultry intake reduced significantly in the experimental group,except for cereal ,milk and soy nuts intakes ,the rest intakes achieved the recommendation for lactating women from Chinese Nutrition Society .The zinc content in breast milk increased while calcium , iron contents showed no significant changes in the control group .The zinc ,calcium contents in breast milk increased while iron content showed no significant changes in the experimental group .Conclusion The individual diet instruction can improve the dietary pattern of lactating women ,increase the intakes of nutrients and minerals as well as zinc , calcium contents in breast milk,but iron content shows no significant change .
