Popis: The chapter comprises the role of gut microbiome and beneficial bacteria (probiotic) to boost the overall health. The GI tract is described as the body’s largest immune organ. The intestinal microbiota has a vital role in the body’s defence system. The most important factor that determines gut health is the microflora or gut flora. Our gut comprises diverse and hundreds of trillion bacteria and it comes in both good, i.e. beneficial bacteria, and bad, i.e. harmful bacteria. So it is mandatory to keep the beneficial bacteria for a better health. Microbes considered to be beneficial usually ferment carbohydrates, do not produce toxins and may have a range of potential benefits for the host. Such microbes include Bifidobacterium, Eubacterium and Lactobacillus. These beneficial bacteria are called probiotic. To get flourish good bacteria in the gut we need to feed it with a proper nutrient called prebiotic. A prebiotic is a special type of soluble non-digestible plant fibres that nourish the beneficial good bacteria in the gut. The synergy of the probiotic and prebiotic components in the gut provides a stable and relatively uniform gut microbiome and thereby boost the gut health and immune system.
