Question:
Yes there is!!!
Answer:
No evidence at all...just oft-repeated internet scares which have less validiity than sightings or Bigfoot!
Aspartame is perfectly safe but those who feel it is not are free to avoid it.
But in order to convince OTHERS, the proper way is to provide EVIDENCE, not just heresay.
Don't you think the SUGAR INDUSTRY has done studies to prove how awful aspartame is. If they got the slightest CLUE, don't you think they'd use their immense assets to TRUMPET the dangers everywhere loud and clear. They got NADA!
Silly fake doctors using silly websites to drum up silly fake scares benefits nobody, but it's a free country so we must abide these quacks.
Answer:
I would say that if you are fine with it, go for it! I know people who get headaches from it, so it's different for everyone. I eat/drink products with it and don't mind. It's a controversial nutrition issue! I chew sugar free gum often.. I would probably be getting cavities if I didn't since I chew gum so much. I also drink diet sodas because I like the taste better and don't get full from them. I don't overdo it though. I know gum is tiny, and I don't drink sodas very often. I might drink one when I'm going out to eat every now and then, but I don't have them most days. I only buy them occasionally and drink mostly all water.
