My doc and I have been having this debate on RS. He is not a fan at all. We know I have a yeast problem so he is saying a prebiotic like MOS is much safer then trying to take rs with probiotics. I dunno the answer but.. I know this. When I take RS, (not just eat beans but make it a goal to get rs and use things like poato starch,) my plasma ammonia goes sky high. We've done two blood tests now where that was the only change I made because I was being stubborn and taking the interwebz as gold. I had gotten my ammonia down to normal by addressing my pathogens and using butyrate. I think the rs is effecting my pathogens so other then normal food consumption, I'm out of this lil experiment. I cannot be good for us to eat straight up potato starch like many are doing. He's a phd and made me well, so I'm gonna just go with it. My gut tell me this RS thing is just gonna flip the switch to a yeast issue for many. I've started MOS with my custom probiotics, so well see how that goes.
