Why is inulin less effective for older kids and adults?
As children age, the inulin becomes less and less effective at controlling bacterial overgrowth. I believe this is due to the natural maturation of the intestinal bacteria as children mature into adulthood. We are not just trying to suppress “gut bacteria” as a singular entity, we are needing to suppress and balance over a thousand distinct species within the large intestine, all of which have their own unique characteristics. nnThe species of bacteria that tend to overgrow in the small intestine of a younger child (let us call them species A) may just tend to be more sensitive to the prebiotic effects of inulin. As a result, inulin is more effective in smaller children.nnAs the child’s intestinal bacteria naturally mature with age, species that are less sensitive to the effects of inulin (let’s call these species B) might be more likely to cause overgrowth and make inulin seem to lose its effectiveness in balancing the intestinal bacteria.
