| Probiotics – For a Healthy Gut
The concept of administering “Probiotics” has been advocated for humans as well as for animals, poultry and for aquatic organisms.
The role of probiotics….
Microbial colonization begins
after birth but the development of the intestinal microflora and
the gut barrier is a gradual process. The primary role of the gastrointestinal
tract is to digest and absorb nutrients to meet the metabolic requirements
and demands for normal human growth and development. Protection
against potentially harmful agents is ensured by many factors, including
saliva, gastric acid, peristalsis, mucus, intestinal proteolysis,
intestinal flora, epithelial cell membrane etc. A delicate balance
exists between the intestinal micro flora and the host and any upset
of this structure esp. that which is caused by anti-bio-therapy,
leads to diarrhea and other acute or chronic disorders.
The demonstration that the gut flora is an important constituent
in the intestines defense barrier has introduced the concept of
probiotic therapy – therapeutic application of potentially beneficial
microorganisms. Promising research has specifically evaluated the
physiologic functions of intestinal bacteria to maintain and support
health. This has led to the development of functional foods that
contain beneficial natural ingredients like probiotics. Probiotics
offer an attractive treatment alternative secondary to the effects
of antibiotics has on delaying re-colonization of the normal intestinal
flora. Continuous administration is required for the maximum realization
of the probiotic effect.
