The gut affects the immune system.

Every day with food, a huge amount of proteins and pathogens alien to us enter the intestines - substances that can cause diseases. Therefore, the intestines have adapted to ensure that these same substances are neutralized as quickly as possible. Including for this, microflora lives in it. A significant part of the immune system is located in the intestines, so the work of the digestive tract affects the entire body. A poorly functioning gut can lead to asthma, migraines, allergies, and even autoimmune diseases (diseases in which cells of the immune system attack their own bodies).
