I've heard this to be the case with regular (i.e. gelatin-based) marshmallows.

I was recently able to buy a large bag of vegan marshmallows. While they tasted exactly like the real thing, and had the same texture and everything, it didn't seem to affect my output at all, which I thought I was interesting!

One GI doctor told me that arrowroot powder can be used to slow down output, too. I haven't tried that one!

That is interesting. Maybe the difference in ingredients. I never tried this marshmallow thing before because i tbiught the sugar would actually make you go but no it actually works for me. 

@veganostomy That is interesting. I don’t know what arrowroot is, but my kids liked Arrowroot Biscuits when they were little - they were the first hold-in-your-hand food for babies the pediatrician recommended. They were on the shelf with other cookies in the grocery store; I wonder if they are still made, and if we ostomates might find them useful.

@llholiday  ... That was how my kids came to enjoy arrowroot biscuits as well. It was their first hand held treat also recommended from the pediatrician & was said good for a teething baby as they could gnaw away at the biscuits and without fail  they also made a gross mess! Lol! 

I went & googled "Arrowroot, where it comes from & is it good for consumption".  Most of what I read said that there wasn't enough research on it.  It comes from the root of the arrowroot plant. It is a starch when used in baking and grows in India, Africa, Australia and  other countries.   🤔...  I think I'll stick to corn starch in baking..... . . . I also read the Health Benefits of Arrowroot & it said it was known to combat diarrhea & irritable bowel. There's actually a lot to read on this starch, so if your curious, go google it!  👓 😎 🕶 ... !
