The History Of Probiotics by anamaulida


									Probiotics have become the focus of much interest from parts of the
public that take personal health very seriously. They have been
introduced as health products alongside many other supplements and
multivitamins. These supplements, however, are not merely exterior
elements that scientists or other researchers have determined to be
useful for human health. These supplements are actually microbes,
bacteria and other microorganisms that already live inside human bodies
and play integral roles in human biological processes. What Are
Probiotics? They are already present in the human system and are actually
critical for maintaining good health. An excellent example of these
entities, and one that may already be known to many people who are
otherwise uninformed on the subject, is the colony of microorganisms that
exists in every person's intestinal tract. The specific probiotic inhibit
the development of toxic bacteria in the waste matter passing through a
human digestive system. Since the discovery of the probiotic, some
manufacturers of health-related products and supplements have developed
probiotic substances that can be taken in pill form or added to food in
order to boost the positive activities of these microbial creatures in
human biology. They have also been identified in certain foods, such as
yogurt or other fermented foods. These foods are then encouraged or
supplemented with more probiotics and sold as health-inducing substances.
History of Probiotics Artificial uses of these products were originally
considered in the early 20th century by a Russian scientist. He suggested
that doctors could make modifications to bacteria in the intestinal
system by replacing detrimental bacteria with probiotic microbes that
would engender health rather than threaten it. This scientist, Elie
Metchnikoff, believed that much of the aging process was due to toxic
activity in the bowels which had certain injurious bacteria as their root
cause. He believed that their replacement with a probiotic could stop or
even reverse the aging process. Among the known probiotics at the time
were the lactic-acid bacteria in fermented milk. Metchnikoff made a
connection between groups of people who lived much of the year almost
entirely on fermented milk and their exceptionally long-lifespans. He
alleged that seeding the lining of the intestine with these bacteria
would destroy proteolytic bacteria which he believed were responsible for
the aging and weakening typically seen in shorter-lived people. So
convinced of the possible benefits was Metchnikoff that he began drinking
sour milk that he had fermented with lactic acid. Many others in Paris,
where he lived, began to follow his example and added these supplements
to their diets. Interested and working at the Pasteur Institute in Paris
along with Metchnikoff was a French scientist by the name of Henry
Tissier. He discovered the dominant presence of a certain bacteria in the
intestines of breast-fed babies. These microbes received the name
bifidobacteria. Their probiotic function appeared to be the deterrence of
diarrhea caused by the toxic proteolytic bacteria. In 1917 more probiotic
discoveries were made as World War One raged across Europe and diseases
broke out among soldiers both healthy and wounded. Alfred Nissle, a
German professor, extracted bacteria known as Escherichia Coli from fecal
matter produced by a soldier who demonstrated immunity against a
particular strain of dysentery. He isolated the strain of bacteria and
used this early supplement to help other patients fight infections of the
gastrointestinal tract and dysentery in general. Up through this time and
long afterward the term probiotics was not known to the world and
scientists had not consolidated their learning about the issue to verify
that they were on to something. In 1953, a scientist named Werner Kollath
contrasted these substances with the recent discovery of antibiotics,
which were used by the body and artificially to attack and kill
infections. According to Kollath, the probiotic stimulate beneficial
activities rather than destroy the negative activities of other bacteria.
Finally, in the 1980's researchers came up with an improved definition
for these bacteria which is widely used today. This definition says that
probiotics are microbes which beneficially supplement an animal by
improving intestinal fortitude and bacterial balance. In the recent past,
adding supplements to diets or eating foods already rich in probiotic
substances has been recommended by various health experts around the
world. However, many people protest this recommendation and point out
that there is no conclusive proof that ingesting substances laden with
these bacteria help people in any way. The most common claim made by such
promoters is that the probiotic present in their product help with
digestion. Possible Positive and Negative Side Effects Of Probiotics
While they are identified as natural to the human system and overall
beneficial, they have been shown to cause harm when added artificially to
the nourishment regimen of certain people. They appear to increase the
death rate of patients who currently suffer from pancreatitis. Intake of
these microbes has also been linked to increasing the sensitivity of
children to allergens of all sorts. However, data also exists supporting
the idea that these microorganisms can boost the immune systems of people
that are already desperately ill. Controversy over the effectiveness of
probiotic rages on today in the scientific community.
