I am just curious but what is so wrong with those gummy bears that they cause umm... explosions after only eating a handful?
The particular artificial sweetener used has the tendency to, shall we say, "get its revenge". (Honestly, I have this problem with ANY artificial sweetener - but that particular one is known for hitting people who can tolerate, say, aspartame or sucralose.) Same deal as those Pringles a while back that used that olestra stuff - it basically runs right through you and wreaks havoc.
Unfortunately, they seem to be transitioning all gummy candies they make to using that sweetener...
It's a type of sugar alcohol. Some people tolerate sugar alcohol okay, some do NOT.
For a very long time, the only thing I ever saw sugar alcohols in were sugar free gum, maybe diabetic sugar free candy, and the occasionally lollypop. Those were usually malitol, sorbitol, and xylitol. They seem to be sneaking their way in a lot of other foods now, I assuming it'd an attempt to lower the refined sugar used or calorie count. I've known more than one person to fall afoul of the sugar free gum and candy bits.
Oh, olestra, how I hate thee. It's like a war was taking place in my intestines. One handful of anything containing olestra, will have me on the toilet for three to five days. It gives me the severe cramping, explosive-mucus laced diarrhea, and causes me to sweat profusely. Seriously, I've had both dysentery and e-coli poisoning that I had less toilet time with than with one handful of olestra laden potato chips.
