Fermented foods enhance gut health through the introduction of beneficial probiotics and help balance the gut microbiome. Foods like yogurt, sauerkraut, and kombucha contain live cultures that promote digestion and nutrient absorption. These probiotics contribute to a healthier intestinal environment, and can prevent or alleviate gastrointestinal issues such as bloating and constipation. Additionally, fermented foods may strengthen the immune system and positively impact mental health by influencing the gut-brain axis. Regular inclusion of these foods in the diet can foster overall gastrointestinal well-being.
