New health foods……

Probiotic FoodsMetchnikoff claimed that the intake of

yogurt containing lactobacilli results in a reduction of toxin-producing bacteria in the gut and this increases the longevity of the host.

Probiotics can be defined as –

“A live microbial feed supplement which

beneficially affects the host animal by

improving its intestinal microbial balance.”

Beneficial effects of probiotic foods Produce lactic acid- lowers the pH of intestines and inhibiting

bacterial villains such as Clostridium, Salmonella, Shigella, E. coli, etc.

Decreases the production of a variety of toxic or carcinogenic metabolites.

Aid absorption of minerals, especially calcium, due to increased intestinal acidity.

Production of β- D- galactosidase enzymes that break down lactose .

Produce a wide range of antimicrobial substances -acidophilin and

bacteriocin etc. help to control pathogenic bacteria .

Produce vitamins (especially Vitamin B and vitamin K)

Act as barriers to prevent harmful bacteria from colonizing the

intestines

An example:

Disease Antibiotic treatment

Diarrhea Disturbance of intestinal microbiota

Clostridium overgrowthproduces toxin

How can probiotics help in this case?Disease Antibiotic treatment Probiotics Disturbance of intestinal microbiota

Microbiota Clostridium overgrowth in balance produces toxin

Use of probiotics…..

All probiotics works effectively, if taken after meals, when stomach acid is lowest.

Stomach acid destroys up to 99.9% of probiotics, if taken before a meal but only about 90%, if taken after meal.

Thus, after meal intake ensures maximum delivery to the small intestine, where they reproduce rapidly, populating the colon.

They do most of their good work in the small

and large intestines, but they also help

the mouth and esophagus to remain uninfected.
