[Prebiotics and probiotics in infant nutrition].

Many studies have recently analyzed the modulation of the intestinal microflora showing a benefic effects reducing the number of enteritis, improving the oligoelements absorption and stimulating the immunitary system. To do so three way are available: the use of prebiotics, the use of probiotics and the symbiotic way. Prebiotics are non-digestible oligosaccharides that can stimulate selectively the growth bifidogenus bacteria. Probiotics are dietary supplements made of live micro-organisms which improve the microbial environment of the gut. In this review literature is examined the possible efficacy of prebiotics and probiotics in the pediatric age; however, the studies available do not permit to obtain definitive conclusions.
