Modern research proves that the gastrointestinal tract functions as an autonomous neural network. The bacterial community (microbiome) consists of trillions of microorganisms that are in constant symbiosis with the internal environment. They synthesize crucial neurotransmitters, directly affecting the emotional background, sleep quality, and cognitive abilities.
In addition to mood regulation, the gut acts as the primary line of defense. About 80% of all immune cells are concentrated in the mucous membrane of the digestive tract. When the bacterial balance is normal, this barrier flawlessly recognizes and neutralizes unwanted agents. But if the balance shifts towards unfriendly flora, protective functions critically decrease, opening the way for the accumulation of waste products.
