So. I have some Quest Hero protein bars left over from pre-surgery and they're made with a type of non digestible sugar called Allulose. I don't want to try it and dump. Has anyone used Allulose with success?

My nutritionist said no sugar alcohols at all but I think they tend to treat them all the same as maltitol that tends to be the worst when it comes to gastric distress. But xylitol and erythritol don’t cause gastric distress and I found neither did Allulose. The one thing about allulose is it’s derived from sugar. My nutritionist said stick to anything below 4 grams of sugar. Which I ate less sugar prior to surgery (low carb) I haven’t gotten up to eating protein bars again yet. I can’t say if the hero bars would cause dumping and every person is different in what causes dumping. I can only suggest to try a bite and see how your body reacts. For some people even if it’s a sugar alcohol their body sees it as sugar. I’m sorry if that’s not helpful.

Thank you so much for your reply. It was helpful!

Just a follow up for those of you interested. I have experimented with this, and as far as I can tell, Allulose does NOT cause dumping in bypass patients. Ymmv

I've had Quest Nutrition bars... no dumping here. Then again, I have also been eating Halo Top without dumping.

It’s good to know about allulose, I don’t know when I’ll get to eat protein bars again. They were always my go to when I wasn’t up to a meal. Especially breakfast or dinner. The Hero bars are good. I wish quest hadn’t switched to using corn fiber but I did like their bars. Another favorite is No Cow bars. And oh yeah one bars.

Halo Top was dinner for me when I didn’t feel like eating. I haven’t tempted myself with it yet. Even though I have yet to be able move past the liquid protein phase, except for some BariatricPal soup or noodle soup. Which even the noodles make me feel sick. So I’m very tempted by halo top. I’ve seen some other new Keto friendly ice creams in the store. I wonder which one has the most protein per portion. I don’t think I’d be very good making my own. I did try to make protein ice popsicles.

Thanks for the info, I dumped once and never want to do that again. I had surgery 5/23 and like you having a hard time moving past liquids and full liquids. I will say pan seared scallops are little protein balls and I have been able to tolerate them. Finally able to get Protein up to the 50's in a day. Going out to get a few Protein Bars you use now. Good luck!!!!

Tried an An Quest Vanilla Caramel bar, oh it tasted almost Wickedly Sickened sweet, did fill me up temporarilymvThe once or twice I tried even a mini-nibble of a sugar- containing item, had to Spit out, the Thrill Is Gone & I wonder that I used to eat that stuff!
