Fermented foods like yogurt, kefir, and sauerkraut are natural sources of probiotics, which promote gut health by enhancing the microbiome. These foods contain live bacteria that can improve digestion, boost immune function, and provide other health benefits. Probiotics can help prevent gastrointestinal issues and support overall well-being. Incorporating these foods into a balanced diet can be an effective and delicious way to increase probiotic intake, contributing positively to digestive health and potentially lowering the risk of certain diseases.
