摘要
随着人们生活水平的提高，如何追求健康长寿逐渐成为人们日常生活谈论的热点。于是，不知不觉中，益生菌保健法从盛行已久的日本及欧洲传到了中国。益生菌属于乳酸菌，但并非所有的乳酸菌都称得上是益生菌。成为益生菌必须符合下述7个条件，即①能够耐受胃液、胆汁、以存活状态到达肠内；②能够在肠内繁氇③被科学试验证明能够改善肠内菌群；④确保安全性；⑤原来就属于肠道菌群的一种；⑥存活在食品中并能保持有效菌数；⑦价廉且容易处理。其产品一般可以改善微生物与酶的平衡或刺激特异性与非特异性免疫，从而改善肠道菌群构成，抑制有害菌及有害物质，调节免疫力，降低胆固醇等。因此，益生菌产品的前景和开发应用是食品、医学界的新领域，对人体健康有举足轻重的作用。
