The human gut microbiome has become one of the most exciting areas of medical and nutritional research. Trillions of microorganisms living in the digestive tract influence not only digestion but also immune function, metabolism, inflammation, and even mental well-being. As scientific understanding continues to evolve, healthcare professionals, wellness practitioners, and individuals interested in preventive health are increasingly seeking evidence-based education on the microbiome.
The Stanford Gut Health and the Microbiome online micro course, developed by Stanford Medicine and delivered through GetSmarter, introduces learners to the science behind the human microbiome and its role in overall health. Through an accessible two-week curriculum, participants explore how diet, lifestyle, environmental factors, and emerging precision health therapies influence gut health and disease prevention.
According to the official course information, humans host an estimated 10 to 100 trillion microorganisms in the gastrointestinal tract. Research also suggests that fermented foods may increase microbial diversity and help regulate immune responses, reinforcing the growing importance of nutrition in maintaining a healthy microbiome.
