Your Gut Microbiota
What is the microbiome?
The intestine is not only our digestive organ—it is also the habitat of trillions of tiny living organisms, the so-called microorganisms: bacteria, viruses, yeasts, and fungi. The set of all microorganisms that live in our body is called the microbiome.
What role does the microbiome play in the gut?
It is well established that a healthy gut microbiome is important for our overall health. However, there is no exact, universal definition of what a healthy gut flora should look like. This is because each person's microbiome is made up of different microorganisms. In general, the more diverse the microbiome, the better. However, the microbiome does not always remain the same; on the contrary, it is constantly changing—for example, due to what we eat, our environment, or our age.
How does the gut microbiome contribute to overall health?
The microbiome of our intestine performs multiple functions:
Digestion and Metabolism:
Helps break down and assimilate nutrients and affects the absorption of fats and sugars in the body.
Mental Health:
It affects our behavior and mood through the so-called “gut-brain axis,” communicating with the brain through the bloodstream and nervous system.
Immune System:
The gut is our largest immune organ, and the microorganisms that live there help defend against unwanted organisms.
Intestinal Barrier:
Supports the function of the intestinal wall in keeping harmful substances and unwanted organisms at bay.
