Researchers Find Gut Microbiota and Mental Health Connection

Groundbreaking new studies are revealing the connection between gut health and mental health.
Researchers have known about the connection between the bacteria that live in your gut and the brain for some time, but when it comes to how closely they’re connected science has just scratched the surface. Now in a systematic analysis published in the journal Clinical Psychology Review researchers looked at 26 studies that assessed the role gut biology plays in anxiety and depression.
The findings showed people with anxiety and depression had different levels and types of microbes in their gut, compared to people without anxiety and depression. The digestive tract of people with anxiety and depression contained more pro-inflammatory bacteria species and had less of the type of bacteria that help regulate the central nervous system.

Your Body Is a Superorganism Thanks to These Microbes

Dr. Bruce Lipton, Ph.D., a pioneer in the field of epigenetics who worked as a stem-cell biologist has effectively bridged the gap between mind, body, and spirit. Of particular note is his approach to the immune system, a widely appreciated (yet poorly understood) function of the body.
We Are Made of Microorganisms
As humans, we each possess a microbiome, a community of microorganisms (such as bacteria, fungi, and viruses) that inhabit the body. Our bodies are home to about 100 trillion of these microbes, and their role in protecting us from disease cannot be overstated: They are not just necessary, but crucial, to human life on a great many levels.
Microbiome research is an emerging field in which researchers investigate how the bacteria that live in and on our bodies affect our health and states of mind. Beneficial microbes in the gut have much to do with how efficiently we can extract calories from different kinds of food, how likely we can escape colon cancer or heart disease, and even how we metabolize different kinds of drugs.
And, as Lipton teaches, these microbes regulate a wide array of aspects related to both mind and body—from the removal of toxins to gut feelings, and from sleep patterns to appetite. In fact, because of their role in the production of certain hormones such as serotonin, a deficiency in the microbiome literally affects happiness levels and may contribute to anxiety and depression.
