The intestine contains almost 2 kilograms of bacteria

The human body is almost entirely composed of microorganisms. However, frightened before the time is not necessary, writes these creatures - not an alien life form. For the trillions of microscopic life forms of the human body is home.

"We are, in fact, only 10% of people, and all the rest - germs" - says Dr. Roy D. Slitor of the Irish Institute of Cork. For four years a thorough study of the subject, he concluded that the true role of the bacterial populations living in the human body, unfairly belittled.

Our relationship with single-celled creatures were so close that progressive scientists now consider man and his living bacteria as a single superorganism. "Today, the bacteria are considered as a virtual body waste products which is significantly higher than that of the liver," - explains Dr. Slitor.

According to him, the human body contains about 500 different species of bacteria. Their incessant reproduction in an adult population of about 100 trillion-celled creatures - almost ten times more than the trillions of cells that make up the human body itself. For example, only in the intestine contained nearly 2 kg of bacteria.

According to Dr. Slitora, bacteria not only our companions, but also irreplaceable helpers. "This bacterial and human interaction for the most part is symbiotic - says the scientist. - This means that in exchange for food bacteria are involved in the processes of digestion, produce vitamins and strengthen our immune system. " In addition, the friendly microorganisms defend the host against infectious agents, fighting the "hostile" bacteria.

For lovers of yogurt and other "live" fermented milk products, this news is certainly good. However, Dr. Slitor warns that strengthen the ability of "probiotic" products is very short-lived. "Most of these bacteria do not stay in the body. They pass through the body without being able to organize the colony, "- he says sadly. On the other hand, the constant use of such products can contribute to the beneficial bacteria colonies. This is especially true when the body is weakened by taking antibiotics.
