目前,益生菌越来越被科学界和消费者认可。随着对益生菌的研究不断增多,大部分国家和地区的科学组织都对益生菌提出过相关的科学共识和应用指南,但是这在全球范围内并没有统一。为了引导益生菌产业健康发展,让益生菌在促进人民健康中发挥更好的作用,本文旨在系统总结目前一些主要国家和团体组织对益生菌的科学共识和应用指南,以期为营养卫生工作者和消费者提供科学可行的应用指南。现有的科学共识和应用指南大多数是针对特定的健康问题提出使用特定益生菌菌株的建议,其中有5种健康问题被2个及以上的应用指南或科学共识推荐使用益生菌,并提及了干预剂量与时间,这些健康问题包括急性胃肠炎、抗生素相关性腹泻、院内感染腹泻、婴幼儿肠绞痛和坏死性小肠结肠炎。然而,要系统地广泛使用益生菌,仍需要更多高质量研究的支持。

目的研究益生元干预对肠道菌群的影响,基于肠道菌群数据建立模型预测摄入益生元后双歧杆菌的变化。方法将35名健康志愿者随机分为2组,分别接受16 g/d低聚果糖(FOS)或低聚半乳糖(GOS)干预,干预时间9 d,采集第0、5、9天粪便标本进行16s r RNA基因高通量测序分析,分析两种益生元干预对肠道菌群结构、多样性与功能的影响。用随机森林方法区分益生元干预5 d后双歧杆菌变化,并用初始的菌群构建一个连续型指数(index),实现指数与双歧杆菌实际变化量相关联,而后,对模型进行验证。结果 FOS干预5 d后降低肠道菌群α多样性,9 d时回升,GOS在干预5、9 d时α多样性均下降。两种益生元对β多样性影响均无统计学意义(P>0.05)。通过随机森林方法建立的预测模型,ROC曲线下面积为89.6%;建立的指数与双歧杆菌变化量关联r值为0.45(P<0.01),验证模型r值为0.62(P<0.01)。结论益生元干预可迅速降低肠道菌群α多样性。根据干预前的肠道菌群预测服用益生元后双歧杆菌的变化,预测效果良好,此方法为精准膳食的实现奠定基础。
