A balanced and species-rich bacterial colonization in the intestine has a positive effect on your general immune system. If you want to support the useful microorganisms of your intestinal flora and strengthen your immune system, you can take probiotic food supplements. Natural yoghurt, kefir, pickles and sauerkraut also contain living microorganisms that colonise the intestine and thus support your microbiome in defending against infections. Prebiotic foods also promote the healthy growth of intestinal bacteria: Prebiotics are found, for example, in artichokes, chicory, flea seeds and flaxseed. Intestinal flora, immune system and nutrition are thus in an effective mutual relationship.
