Gut microbiota is the microbial ecosystem in your digestive tract. There are comparable number of microorganisms in our intestines as there are cells in our body, but in terms of genes, for each human gene there is 100-1000 microbial genes.

Today, it is known that the gut microbiota plays an important role in influencing our health and well-being. Each bacterial species has its own functions and, according to that, they can be conditionally divided into "useful" and "harmful" bacteria depending on their proportions.

Changes in the composition and diversity of the microbiota are associated with a variety of frequently occurring autoimmune and other diseases such as allergies, obesity, gastrointestinal diseases (eg irritable bowel syndrome), cardiovascular diseases, diabetes, rheumatoid arthritis, etc.

Gut microbiota can vary in time. Age, lifestyle, medications, disease and diet influence its composition. Diet is an important factor as well, the composition and amount of food needed for for your body supports the "beneficial" bugs and suppresses the "harmful" bacteria, thus reducing discomfort and improving the quality of life.
