A review on probiotic dairy products and digestive health

Abstract

Probiotics are live bacteria and yeasts that are good for human health, specially for digestive system. Human body is full of bacteria, both good and bad. Probiotics are often called "good" or "helpful" bacteria because they help keep our gut healthy. The health promoting benefits and efficacy of probiotics has been demonstrated in many models of gastrointestinal disease. Probiotics have an antimicrobial effect through modifying micro flora, secreting antibacterial substances, competing with pathogens and bad microorganism to prevent their adhesion, competing with nutrients necessary for pathogen survival, producing an antitoxin effect and reversing some of the consequences of infection on the gut epithelium. Fermented milks, kulfi, cheese, enriched yoghurt, yoghurt-like products are the commonly used Probiotic food preparation.
