Fundamentals of the Human Microbiome and Health

The human body is home to trillions of microorganisms that play a fundamental role in regulating our health, metabolism, and immune defenses. Understanding how these complex ecosystems work allows you to grasp the science behind modern health, nutrition, and disease prevention. In this foundational text-based course, you will learn the core biological concepts behind the human microbiota and how microbial balance shapes everyday physiological functions. What you'll learn: - Understand essential terminology, taxonomy, and ecological principles of the human microbiome - Explore distinct microbial communities across the gut, oral cavity, and skin - Examine the biochemical interactions between microbial metabolites and human metabolism - Understand the gut-brain axis and mechanisms of immune system regulation - Learn how modern sequencing technologies, diet, and lifestyle factors influence microbial diversity The course begins with foundational vocabulary and biological concepts before progressing systematically through body habitats and real-world health applications. Designed entirely for beginners, no prior background in biology or medicine is required. Start reading today to build a solid foundation in microbiome science.
