Prebiótík

Prebiótík are non-digestible compounds that selectively stimulate the growth and/or activity of beneficial bacteria in the colon, thus improving host health. They are essentially food for the probiotics, which are live beneficial microorganisms. Prebiotics are typically carbohydrates, such as specific types of fiber, that are not broken down by human digestive enzymes but are fermented by gut bacteria. Common examples include inulin, fructans, and galacto-oligosaccharides (GOS). These compounds are found naturally in many fruits, vegetables, and grains, including bananas, onions, garlic, chicory root, and whole grains.

The fermentation of prebiotics by gut bacteria produces short-chain fatty acids (SCFAs) like butyrate, propionate, and acetate. These SCFAs have a variety of beneficial effects, including providing energy for colon cells, helping to maintain the integrity of the gut lining, and influencing immune function. By promoting the growth of beneficial bacteria such as Bifidobacteria and Lactobacilli, prebiotics can contribute to a healthier gut microbiome. This can potentially lead to improved digestion, enhanced nutrient absorption, and a strengthened immune system. The concept of prebiotics is closely linked to probiotics, and together they are often referred to as synbiotics, which aim to provide a synergistic effect on gut health. Research into the specific benefits and optimal types of prebiotics is ongoing.
