The gut microbiome plays a significant role in health by influencing inflammatory responses and brain function, and can be adjusted through dietary choices. Fermented foods significantly outperform high-fiber diets in improving gut health and reducing inflammation, leading to better cognitive function, sleep, and immune response.
