Fermented foods can significantly improve gut health by enhancing the diversity of gut microbiota. Through the fermentation process, beneficial probiotics are produced, which can help restore balance in the gut. These foods, such as yogurt, sauerkraut, and kimchi, not only introduce beneficial bacteria but also contain prebiotics that fuel healthy bacteria already present in the gut. This improved microbiota balance can enhance d digestibility, bolster the immune system, and even regulate mood through the gut-brain axis. Including fermented foods in the diet supports overall gut function and can alleviate issues like IBS and bloating.
