The intestinal wall contains 500 million neurons which make up our enteric nervous system and produces 30 different neurotransmitters. This system is responsible for balancing our mood, reducing stress and anxiety and keeping our overall mental health in check.
In several studies with mice, researchers were able to alter the mice’s behavior by changing their gut bacteria. Additionally, intestinal bacteria can influence processes in the brain through the gut-brain axis.
The moral of the story is that your gut absolutely affects your brain, so if you are struggling with stress, anxiety, brain fog, mental fatigue or depression the first thing you should do is check your gut.
