Consuming fermented foods benefits gut health by providing live beneficial bacteria known as probiotics. These bacteria help maintain a healthy balance of gut microbiota, which is crucial for effective digestion, nutrient absorption, and immune function. Fermented foods such as yogurt, kefir, kimchi, and sauerkraut can enhance digestive health and may alleviate symptoms of conditions like irritable bowel syndrome (IBS) and constipation. Additionally, a balanced gut microbiome is linked to improved mental health and overall well-being.
