Also known as: Fructo-oligosaccharides, Prebiotics

The addition of FOS to a food prevents infectious diarrhoea caused by the proliferation of dangerous bacteria in the intestine,while providing adequate nourishment to intestinal cells to facilitate their regular regeneration.

A little background information

Fructo-oligosaccharides (FOS) are fermentable fibres.They are not digested, but are nevertheless rapidly fermented by the bacteriain the colon, resulting in the release of small-sized fatty acids (known asvolatile fatty acids) that:

  • acidify the intestinal medium ;
  • are excellent nutrients for cell maintenance and renewal ;
  • Line the walls of the large intestine.

Its role in the body

Through fermentation, FOS is a direct source of nourishment for the cells of the large intestine. But they particularly promote the growth of specific bacterial flora (bifidus and lactobacillus) that have well-known beneficial effects on the health of the digestive tract:

  • they inhibit the development of pathogenic bacteria ;
  • They improve digestion and nutrient absorption.

FOS supplementation in the food of bitches used for breeding helps increase the antibody count (IgM) in the milk, which promotes the good immunity of the puppies.

Natural sources

FOS are synthesised by a fungus (Aspergillumsnigricans) in the presence of sugar, or saccharose, which is composed by the association of a glucose molecule and a fructose molecule. The fungus secretesan enzyme that permits the addition of extra fructose molecules to form FOS.
