How Gut Bacteria Control Our Health

The Microiome Revolution: Why Microbes Control Your Life

Jack A Gilbert

The Microbiome Revolution provides a brief and user friendly introduction to the essential role the microbiome (the bacteria that colonize our gut) plays in human health. Through their research, Gilbert and other microbiologists have induced obesity, allergies, autism, depression, anxiety, Alzheimer’s, Parkinson’s Disease and other illnesses by manipulating intestinal bacteria in mice. Gilbert contends that specific gut bacteria can even alter behavior.

He stresses that our current obsession with eradicating bacteria (ie prescription antibiotics, antibiotics used on factory farms, antibacterial soap, toothpaste, mouthwash, etc) has dire implications for human health. The human body is an ecosystem in which microbial cells outnumber “human” cells by ten to one. Doctors increasingly view the microbiome as a vital organ, like the liver or kidneys.

Thanks to Gilbert’s crowdfunding site*, his research team has collected the microbiome profiles of hundreds of thousands of people. This baseline has enabled them to identify specific bacterial profiles associated with good health. In general, rural third world residents have the most diverse and healthiest gut bacteria, while urban residents in the industrialized world have the least diverse and the most unhealthy.
