Uuuugh maltitol. My first- and last- brush with it was one nasty experience. I was working in a health food and supplements store at the time and the staff often ate expired protein bars as a lunch (since they were cheap and we received a pathetic salary).
One time, the discounted box in the back store happened to be ultra low carb bars, loaded with maltitol. For the next 3 days, I had severe runs... it got to the point where it was mostly clear water (TMI I know). I was just drinking pints of water and eating bread and bananas, desperately trying to get back to normal. I thought it didn't behave like the flu or a virus because I didn't have a fever or other symptoms but I did not realize what had happened until I spoke to a co-worker. He mentioned he had had a similar incident with carb-free jam.
Nasty, vile stuff.
