Fermented foods offer numerous benefits for overall health by promoting a healthy gut microbiome. They are rich in probiotics, which are live beneficial bacteria that can improve digestive health, enhance nutrient absorption, and strengthen the immune system. Regular consumption may also prevent digestive disorders and contribute to better mental health by impacting the gut-brain axis. Additionally, fermented foods can increase levels of vitamins such as B vitamins and improve bioavailability of nutrients. Foods like yogurt, kimchi, and sauerkraut can foster a diverse gut flora, leading to better overall well-being.
