Microbiota \u2014 a complex ecosystem within us<\/strong><\/h3>\n

The human body is not just a collection of cells, but also home to trillions of microorganisms. The intestines, skin, and mucous membranes are inhabited by microbes, most of which are beneficial bacteria<\/strong>. Scientists believe that the number of bacterial cells in the human body is approximately equal to the number of human cells. The largest number of bacteria is in the intestines, where the so-called intestinal microbiota<\/strong>.<\/p>\n

These bacteria perform dozens of functions that our body could not exist without. They participate in digestion, synthesize vitamins, fight pathogens, modulate the immune response, and even influence our psycho-emotional state.<\/p>\n

Each of these microorganisms has its own specialization. Together, they form a biological shield for the body, maintain metabolic stability, and regulate the interaction between systems.<\/p>\n

What the research says<\/strong><\/h3>\n

In a study published in The Lancet Microbe<\/em> (2022), analyzed the microbiota of over 10,000 people from different countries. It was found that a decrease in bacterial diversity is associated with an increased risk of developing insulin resistance, inflammatory bowel disease, obesity, and depression.<\/p>\n

Quote from immunologist Yuri Nakonechny:<\/strong>
\u00ab"The state of the microflora is the foundation. It affects not only the gastrointestinal tract, but also immunity, allergic reactions, the risk of autoimmune diseases, and even the body's ability to respond to vaccination.".<\/em><\/p>\n

The microbiota is easily disrupted. Dysbiosis \u2014 an imbalance of good and bad bacteria \u2014 can occur:<\/p>\n
