3 Surprising Facts About the Microbes Living in Your Gut


3 Surprising Facts About the Microbes Living in Your Gut

There are billions of microbes hanging out in your gut. Thanks to extensive research, the idea that gut bacteria affects your health is not revolutionary.These organisms living in your gut play an important role in your everyday health and many people know that these microbes influence digestion, allergies, and metabolism.

1. Gut Bacteria and Obesity

Need to lose weight? Why not try a gut bacteria transplant?
New research published in the journal Science suggests that the microbes in your gut may play a role in obesity. However, researchers are still unsure of the extent to which they affect how we metabolize food. Scientists are just beginning to understand the role of gut bacteria in obesity.

2. Probiotics May Treat Anxiety and Depression

Scientists have been exploring the connection between gut bacteria and chemicals in the brain for years. New research adds more bulk to this theory that researchers are calling “the microbiome–gut–brain axis.”

Proceedings of the National Academy of Science has published research showing that mice fed the bacterium Lactobacillus rhamnosus showed fewer symptoms of anxiety and depression. Researchers theorize that this is because L. rhamnosus acts on the central gamma-aminobutyric acid (GABA) system, which helps regulate emotional behavior.1

3. The More Bacteria the Better

Bacteria on the outside of your body can cause serious infections, but bacteria inside your body can protect against it. Studies have shown that animals without gut bacteria are more susceptible to serious infections.

Bacteria found naturally inside your gut help you to maintain our health as well as support a healthy immune system.

The host and the bacteria develop a give and take relationship with your body.  According to a research article published in The Lancet “The host actively provides a nutrient that the bacterium needs, and the bacterium actively indicates how much it needs to the host.”
