I hear both sides when I surf various sites...
Whats the feeling here. Does FOS feed bad bacteria?

Good question Paul,
FOS has been under scrutiny before. Apparently the concerns around it being nutritious to both beneficial and pathogenic organisms stems from studies done using synthetically produced FOS. I have been using FOS (ino the DDS acidophilus) and in the chicolin for quite some time now and have seen almost exclusively positive results. The folks I am working with almost all suffer from some degree of candida overgrowth.
FOS has been discussed here before so I did a little search and pulled up a previous post.
“Studies showing that FOS doesn't have benefits, or even feeds pathogenic organisms, use enzymatically synthesized FOS. Studies using natural FOS (from Jerusalem artichoke or chicory root) show that FOS helps beneficial flora.
Inulin/FOS products can also be manufactured synthetically via a fermentation process as utilized by a Japanese company, Meiji Seika, which markets product worldwide and in the U.S. under the brand name Nutra Flora(R)."


The FOS used in both BioQuest's chicolin and UAS laboratories, DDS acidophilus, are both natural extracts and are not known to feed any non beneficial organisms.

The whole, raw, chicory or artichoke root flours contain FOS as well and are a rare food item that seem to be becoming more and more popular. I have not seen them in my local stores yet and I do not have the nutritional data on them yet but keep an eye out for these as a super natural FOS source.
