This combined with specific soluble and insoluble fibers can basically act as a sweeping cleaning antimicrobial agent in the gut, similar to the concept of the "carrot salad" Curcumin/turmeric also has this action, very, very low bioavailability (good in this context), but gentle antimicrobial action that generally preserves and promotes beneficial species, while inhibiting pathogens Could be potentially useful to combine with PHGG, heavy insoluble/soluble fiber meals like berries, carrots, other fruits/fibers, etc, or even resistant starch
