And no, your attitude is not called for. There's a legitimate body that had called the safety of aspartame into question. Whether it meets your standards is personal. But it's poor form to attack others for citing credible sources (a chemistry teacher is worth following up on for chem matters, which, in this case--again--led directly to a statement by the WHO).

You have simultaneously said it's both been studied excessively and acknowledged the WHO has said it needs more study.

Rando vs WHO. WHO wins. Aspartame may be dangerous. And, incidentally, so may working as a dry cleaner. Which seems like a good warning to put out there. Thank you angry, rude person trolling this thread.

Edit: just googled "cancer rates among dry cleaners" and wow... it seems a number of studies have demonstrated elevated cancer rates among dry cleaners. Here are a couple:

Sweden study

St Louis study
