That's all well and good, HC, but you didn't answer the question:
Do people defending Aspartame as 'safe' have enough EVIDENCE at this point to advise caution?
That's what it boils down to. It doesn't matter what you or I say, or think, there is evidence that points towards CAUTION when it comes to the STILL unknown effects of artificial sweeteners which have been on the market for a relatively short period of time.
From your defense of artificial sweeteners, it's pretty apparent that your answer to the above is "no". Which is fine, that's your opinion. But your opinion is not going to change the multitude of symptoms that people have reported, it's not going to change the fact that artificial sweeteners are still relatively new, and it's not going to change the fact that there's a potential that they are still harmful. And considering the multitude of symptoms reported, caution would be advised.
Think of food as fuel for the body instead of feeding emotions
