The Influence of Gut Microbes on Behavior and Health

Gut bacteria play a significant role in influencing various aspects of our physical and mental health. These microbes, concentrated in the gut, communicate with the brain and can impact personality, mood, energy levels, pain sensitivity, cognition, and hunger. The gut-brain connection, facilitated by the vagus nerve, allows gut bacteria to produce neurotransmitters and psychoactive compounds affecting behavior and mental health. Studies show that gut bacteria can trigger inflammation linked to conditions like depression.
