Gabrielle Fundaro – Gut Health Explained

01: What Is Gut Health?
Although the term microbiome began showing up with increasing frequency in scientific and popular literature earlier this century, scientists still don’t have a widely accepted definition of a healthy gut.
Discover your expert’s functional definition of gut health as it relates to gut disease, diversity, and digestion.

02: Introducing the Gut Microbiome
Explore the human digestive tract to learn how this landscape shapes the microbial community, including such an extensively folded small intestine that its absorptive capacity is 600 times greater than it would be as a straight tube.
Learn how we first acquire our personal set of microbes, and how dozens of factors create each person’s unique microbiome, as distinctive as fingerprints.

03: How Researchers Study the Gut Microbiome
Like any other scientific field, the study of the microbiome begins and ends with the scientific method.
Because this method is slow and the microbiome contains trillions of organisms, thousands of species, and unknown numbers of subspecies, research is complex.
Learn how Koch’s postulates and the work of Dr. William Hanage at Harvard shape the study of the human microbiome.

04: How to Spot Gut Health Pseudoscience
Because scientific research takes time and consumers want answers right now, it’s easy to fall for pseudoscience.
Learn how to recognize misleading claims and popular terms not supported by science, such as “leaky gut.”

05: The Microbiome and Gastrointestinal Disease
Although microbes are often labeled as “good” or “bad,” science shows a more nuanced reality.
Each person’s gut environment is unique, and a microbe beneficial to one individual may be a pathogen for another.
Explore emerging relationships between microbes and disease, even as the full picture continues to develop.

06: The Microbiome and Immunity
Learn how the innate immune system and adaptive immune system work together to maintain gut homeostasis and protect against pathogens.
Discover how the gut immune system connects with the body’s overall immune response.

07: The Microbiome and Metabolic Health
The microbiome plays a crucial role in metabolism and weight regulation.
Examine studies linking the microbiome to energy balance, especially research involving fecal transplants in mice.
Understand why findings related to butyrate supplements have not yet translated reliably to humans.

08: The Gut-Muscle Axis and Exercise
Explore the emerging concept of the gut-muscle axis and how the microbiome may influence muscle metabolism, age-related muscle loss, and athletic performance.
Learn why fiber intake and physical activity remain essential for both overall health and microbial balance.
15 min

09: The Gut-Brain Axis and Mood
The gut-brain axis links the nervous system, gut microbiota, neurotransmitters, and hormones.
Investigate the science behind the idea of the gut as the “second brain” and its potential role in mood disorders.
How much do we really understand about this complex interaction?

10: Common Digestive Complaints
Everyone experiences GI discomfort at times.
If medical tests show no serious disease or indicate a functional disorder like IBS, what can be done?
Learn how food intolerances, medications, and exercise habits may affect digestive comfort.
25 min

11: Eating for Gut Health
Your long-term dietary pattern significantly affects the composition and function of your microbiome.
Explore evidence-based insights into diets such as DASH, Mediterranean, ketogenic, fermented foods, and time-restricted feeding.
Do these popular approaches help or hinder gut health?

12: A Lifestyle for Gut Health
Beyond diet, discover how exercise, sleep, and stress influence gut health.
Learn how physical activity affects the production of immune-regulating metabolites, and how sleep disruption or night shift work can reduce microbial diversity and increase the risk of functional gut disorders like IBS.
