Probiotics positively influence overall health by promoting a healthy gut microbiome. These live microorganisms, found in fermented foods like yogurt and sauerkraut, help in the digestion of food and the absorption of nutrients. They can enhance immune function, reduce the intensity of digestive disorders such as irritable bowel syndrome, and might even support mental health through the gut-brain axis. Regular consumption of probiotics can lead to an improved balance of gut bacteria, contributing to better health outcomes and overall longevity.
