Prebiotics are a source of nondigestible fibers that can induce the selective growth of beneficial bacteria such as Bifidobacteria & Lactobacilli in the gut. Moreover, they have the ability to strengthen the intestinal flora and reduce the number of pathogenic bacteria and toxic metabolites in the gastrointestinal tract. While prebiotics are compounds that facilitate the growth of ‘good bacteria’ in the gut, probiotics, instead, are actual living microorganisms. They are a group of living bacteria and yeast that are naturally present in fermented foods and oral supplements. For example, naturally occurring probiotics are found in yogurt and fermented foods like sauerkraut and kimchi to name a few. For years, they have been widely used to promote human health, especially when it comes to maintaining a healthy digestive system, due to their ability to replenish ‘good bacteria’ during or after a course of antibiotics.
