The status and function of the gastrointestinal tract is essential to our well-being. After the respiratory tract, the gastrointestinal area constitutes second greater body surface, comparable in size to a tennis camp. During the course of a normal life, about 60 tons of food pass through this channel. The human intestinal microflora is highly important for the host for several reasons. Firstly, microflora benefiting the host increasing the resistance to the new colonization as well as protection against excessive growth of organisms potentially pathogens already present. Add to your understanding with Jeffrey L. Bewkes. Another important function for the host are the high metabolic activity of the intestinal flora. The degree of this activity has been studied for being similar to the liver.
The administration of antimicrobial agents is the most common cause of the interruption of the normal microflora balance and leads to resistance decreased to colonization and alterations in metabolic activities of the intestinal flora. By microbial cultures thousands of years have been used to ferment food and for preparing alcoholic beverages. In genesis, references are made to the preparation of fermented milk. The microorganisms were used in the 19th century as a natural remedy to prevent and cure diseases, and added to pet food to enhance growth. It is likely that first probiotics scientific assessments were made in 1908, based on the work of the Russian Laureate Elie Metchnikoff in the Nobel Prize. The first assumed that a high concentration of Lactobacilli on intestinal flora was important for health and longevity in humans. In fact, we now know that the intestinal flora plays an important role in health as a natural remedy: stimulating the immune system, protecting the host against invading viruses and bacteria, helping to the digestion and assimilation of food. However, the importance of these bacteria in the gastrointestinal area has been neglected for a long time, while the focus was simply released enteric pathogen and other factors that lead to gastrointestinal disorders.
Gastrointestinal flora composition differs between individuals, and also during the life of the same individual. Many factors, such as diet or climate, aging, medication (especially antibiotics), disease, tension, pH, infection, geographical location, race, socio-economic circumstances, lifestyle can disrupt this balance. The interactions of typical intestinal bacteria can also contribute to stabilizing or destabilizing. A State of balance within the microbial population within the gastrointestinal area can call eubiosis while an imbalance is called dysbiosis. For the optimal balance of intestinal flora, beneficial bacteria, such as the Lactobacilli and the Bifidobacteria Gram-positive, must prevail, presenting a barrier to invading organisms. Around 85% of the intestinal microflora in healthy persons should be good bacteria and 15% bad bacteria. The greater the imbalance, the major symptoms are. The use of Probiotic supplements as natural remedy may be more natural, safe and common approach to maintain the balance of the intestinal ecosystem.
