Interesting. I bought some to make... marshmallows ( !), and tasted a bit last night. BG went up .8 to 6.7 from a 2-hr-post and 3.5-hr-post meal reading. And is up even further this morning's FBG. It can only be the allulose, methinks. Ah well. I'll take all week to get BG back down again, then maybe do another trial. For self-comparison, 4-5 times that much erythritol does nothing to me.
