Benefaction of probiotics in human gastro intestinal tract

Abstract

In last two decades probiotic bacteria have become most popular due to continuously enlarging scientific research and evidences based on its beneficiary effects on human health. According to previous research work probiotics have documented health benefits outside the gastrointestinal tract; digestive health remains key benefits for probiotics. Recent advances in technology have made more concentrated in-depth analysis on the intestinal microbiota. Generally these probiotics will not only cure or prevent disease, but will mainly focus at maintaining health and reducing risk for disease. Along with the reducing risk factor these probiotics can exert health benefits in people suffering with diarrhoea, constipation, gastro intestinal mucositis and inflammatory diseases of the intestine. Even though maximal mode and mechanism of probiotic action is known, there remains a challenge to identify specific and mixed combinations of strains for explicit health benefits. Intestinal microbiota compositions and activity of genera’s Lactobacillus, Bifidobacterium and Saccharomyces are identified and we may focus on new or existing health targets from new probiotics strains other than strains available in market. The main aim of this review is to update the probiotic bacteria beneficiary properties in gastrointestinal health.
