Bifidus and lactic acid bacteria live as microorganisms in your intestine. They are particularly effective probiotics: They strengthen the intestinal mucosa, fend off pathogens and support the absorption of nutrients. They also create an acidic environment in the intestine, which inhibits the spread of harmful intestinal bacteria. With probiotic foods you can support the population of the health-promoting bacterial strains in your intestine. Natural yoghurt, kefir, pickles, apple vinegar and sauerkraut contain live lactic acid bacteria that are good for your intestines.
Prebiotics in turn support the growth and activity of beneficial intestinal bacteria. Artichokes, chicory, flea seeds, linseed and black salsify contain the polysaccharides inulin and oligofructose. These indigestible food components are not broken down in the small intestine; they reach the large intestine intact, where they nourish the intestinal flora.
The interaction of prebiotic and probiotic foods can therefore help you to build up your intestinal flora after a stomach flu.
