Evidence for the role of probiotics in maintenance of health or prevention of disease is mounting and is supported in some cases by blinded, placebo-controlled human trials. Today, in an era of antibiotic-resistant pathogens and other looming microbial threats, the value of prevention of infection is recognized. Probiotics may play an important role in helping the body protect itself from infection, especially along the colonized mucosal surfaces of the gastrointestinal tract. Probiotic products are available in many different forms worldwide, including pills, powders, foods, and infant formula. In some cases, general health claims are made that cannot be substantiated for the specific strains and levels being used and consumers must therefore beware.
益生菌在维持健康或预防疾病方面发挥作用的证据越来越多,在某些情况下还得到了双盲、安慰剂对照人体试验的支持。如今,在抗生素耐药性病原体和其他迫在眉睫的微生物威胁的时代,预防感染的价值已得到认可。益生菌可能在帮助身体抵御感染方面发挥重要作用,尤其是在胃肠道的定植黏膜表面。益生菌产品在全球有多种不同形式,包括药丸、粉末、食品和婴儿配方奶粉。在某些情况下,会提出一些无法针对所使用的特定菌株和水平得到证实的一般健康声明,因此消费者必须谨慎。
