Medical Science is making strides and that is why we now know that the so-called intestinal flora, consisting of large numbers of bacteria, plays a decisive role in obtaining the energy we need for food and defense against infections.
The intestinal flora that live in our digestive tract is a kind of ecosystem that serves, among other things, to be in good physical activity, create beneficial substances (vitamin K, for example), supplying foodstuffs and strengthen the immune system defenses. Additionally, a protective wall against harmful microorganisms and the potential harm of antibiotics.
In effect, there is great variety of bacteria within the intestinal flora, "Approximately 400 different types from the mouth to the anus", some of which are aerobic and anaerobic other (first need oxygen to live, the latter not).
Humans are born sterile, i.e. without any bacteria in our bodies; however, almost instantly passing through the birth canal, the newborn begins to fill with germs of all kinds. The first to reach the baby's body fluids are placed in the vagina, but roughly the same time enters the digestive tract a number of bacteria found in the environment. This process persists throughout life.
It is true that the foods we consume daily, as well as the environment in which we live are critical to maintain proper intestinal health. That is why doctors and nutritionists recommend that you follow diet that promotes bowel motility and proliferation of bacteria, "healthy" or "friendly."
People including children suffering some disturbance in body which prevents them from properly absorbing nutrients (mal-absorption) due to severe gastrointestinal illness or surgical removal of large portion of the small intestine (short gut syndrome). This situation, who has favored colonization of pathogenic bacteria and bacterial overgrowth, occurs. So common is a picture of malnutrition because there is considerable imbalance in fat absorption, vitamin B12, and carbohydrates. There will also be mal-absorption of proteins in general and frequent diarrhea.
Some of the studies that have caused more excitement in recent years are those related to the action of lactobacilli (bacteria that live in dairy products), the yogurt and milk, food that we know with certainty, produce better absorption by the intestine and are excellent allies in cases of diarrhea.
However, the easiest to care for our intestinal flora is a balanced diet, i.e. "consume plant foods and animal restraint dictated by logic, because in this way managed to colonize properly our body.
Contrary to what one might think, although you have to follow the maxim that any excess can harm us, there is a food that produces harmful effects on intestinal flora. Of course, It is a reality that the indiscriminate use of antibiotics (especially broad-spectrum, which are the most potent) causes a direct decline in the protective bacteria in the body and opens the door to opportunistic microorganisms very aggressive responsible for various diseases.
Fortunately, the intestinal flora is damaged as described above can repopulate quickly because to get back to eating a lot of bacteria.
