Modern scientists with a particular sense of humour or a radical view of the facts argue that we are just a shell for the billions of microorganisms within us. One of the largest microbial communities in our body lives in the intestines. Without our microbial friends, which include not only bacteria but protozoa of all kinds and even fungi (and hardly a tenth of this abundance has been explored), our bodies would not be able to fully digest and absorb food, synthesize useful vitamins, amino acids, and hormones, as well as form the immune defence of the entire organism.

A healthy and balanced gut microbiome is the key to harmonious not only physical, but also mental well-being of the body.

Unbelievable but true: 80% of the human body's immunity is formed in the intestines. Therefore, it is so easy to associate the general state of all body systems precisely with the “modest” gastrointestinal tract, which “merely” digests, absorbs food and eliminates its residues. We will talk about what is important for strengthening the immune system through the gastrointestinal tract. How natural childbirth, breastfeeding, taking antibiotics, eating semi-finished foods, as well as an adverse effect on the gastrointestinal tract system affect the immunity of the whole body, as well as many other interesting topics.
