A Loving God

Thankfully, the gut bacteria don't seem to have the ability to form justified angst on account of it.  Their existence is already miserable enough, so that's a mercy.

They don't need to, they are chemically reactive....and so are we.

Bacteria have been discovered in our guts that depend on one of our brain chemicals for survival. These bacteria consume GABA, a molecule crucial for calming the brain, and the fact that they gobble it up could help explain why the gut microbiome seems to affect mood.

Philip Strandwitz and his colleagues at Northeastern University in Boston discovered that they could only grow a species of recently discovered gut bacteria, called KLE1738, if they provide it with GABA molecules. “Nothing made it grow, except GABA,” Strandwitz said while announcing his findings at the annual meeting of the American Society for Microbiology in Boston last month.

GABA acts by inhibiting signals from nerve cells, calming down the activity of the brain, so it’s surprising to learn that a gut bacterium needs it to grow and reproduce. Having abnormally low levels of GABA is linked to depression and mood disorders, and this finding adds to growing evidence that our gut bacteria may affect our brains.

It’s not yet clear how the microbiome alters the brain. Most researchers agree that microbes probably influence the brain via multiple mechanisms. Scientists have found that gut bacteria produce neurotransmitters such as serotonin, dopamine and GABA, all of which play a key role in mood (many antidepressants increase levels of these same compounds). Certain organisms also affect how people metabolize these compounds, effectively regulating the amount that circulates in the blood and brain. Gut bacteria may also generate other neuroactive chemicals, including one called butyrate, that have been linked to reduced anxiety and depression. Cryan and others have also shown that some microbes can activate the vagus nerve, the main line of communication between the gut and the brain. In addition, the microbiome is intertwined with the immune system, which itself influences mood and behavior.

This interconnection of bugs and brain seems credible, too, from an evolutionary perspective. After all, bacteria have lived inside humans for millions of years. Cryan suggests that over time, at least a few microbes have developed ways to shape their hosts’ behavior for their own ends. Modifying mood is a plausible microbial survival strategy, he argues that “happy people tend to be more social. And the more social we are, the more chances the microbes have to exchange and spread.”



Be a loving God to your gut biome and gain a peace that surpasses understanding.
