cant eat suger free jello
A lot of the new crystal lite flavours (including all of the ones in the squirt bottles) as well as Mio are made with Splenda instead of aspartame - yay! I know because I can't have aspartame either.
If you look carefully you'll be able to find sugar free popsicles made with splenda, and if you need flavouring for other things look for Torani SF syrups, again not made with aspartame.
There are more and more sugar free things out there that are not made with aspartame, for which I am truly grateful.
Post-op I had an aversion to anything with aspartame in it. I think my body was on high alert against anything that was really bad for my body, & aspartame was one of those bad things. In the hospital they served me a bottle of Crystal Light & I about urped (although my stomach was empty)! Just seeing the bottle made me sick. Then they brought me sugar-free Jell-O. Oh dear lawwd I made The Hubs make that stuff disappear with a quickness! Again, I couldn't even look at it.
It was months before I would touch anything with artificial sweetener in it (I use the term to refer to any sugar substitute although I know many claim to be "natural"). I still can't eat anything with sugar alcohols in it (sorbitol, xylitol, mannitol, maltitol are examples). I was an insulin-dependent type-2 diabetic before my RNY. Perhaps that's a reason why I can't have sugar alcohols. Sugar alcohols are not completely digested by the small intestine in those who haven't had RNY surgery, so you can imagine the difficulty someone who's an RNY post-op can have in digesting them at all. Not enough independent research has been done on the effect of sugar substitutes on the general population, so you can imagine the medical community probably has little knowledge about how WLS post-ops react to them.
Your palate changes post-op (or at least mine sure did). You never know what you'll want or what you'll absolutely reject post-op. It really has no bearing on your pre-op food choices.
Nashua Nutrition sells several different brands of protein gelatin (jello). Maybe one of them isn't sweetened with aspartame. That way you are getting protein in at the same time. They have protein puddings too. They aren't bad. I am not sure what they are sweetened with. You could check out their site as they give that information on all the items they sell. I have been buying from them a long time and always get my order timely and it is always right. Good luck.
