Maintaining a healthy gut microbiome positively affects overall health by promoting disease prevention, enhancing digestion, and supporting the immune system. A diverse microbiome contributes to the effective breakdown of nutrients, the production of essential vitamins, and the prevention of harmful bacteria growth. Research indicates that a healthy gut can influence mental health through the gut-brain axis, impacting mood and cognition. Consuming a diet rich in fiber, probiotics, and prebiotics fosters microbial diversity, which is key to sustaining gut health.
