I can tell you this...when Aspartame came on strong in the marketplace, thank you govt. approval, I would get an instant reaction if I ate, or drank anything that contained it. My best friend knew I had said this, but she was a big believer in "sugarless food". We got together every week to paint, and took turns supply lunch, so lunch at her house, dessert was jello, layered with cool whip in neat dessert glasses. I had taken two bites and the eruption started in my belly and I had to excuse myself from the table and head for the bathroom. When I got back to the table, I asked her if it was sugarless jello and she said yes. She apologized profusely, saying she really didn't believe me, that it would affect anyone like that.After that, she promised no more surprises, she believed.
