One of the world’s most common artificial sweeteners is set to be declared a possible carcinogen.
(Edit- Question from OP: downvoters, do you not want me to post stories like this, or are you expressing disagreement with some of the people in the report?)
Unclassified -> possible carcinogen -> probable carcinogen -> carcinogen
As red meat is classified as probable carcinogen, I’d not worry too much about aspartame being substantially more risky than that. Until we have more evidence that is.
I’d be way more worried about ultra processed foods instead, and having aspartame in something would definitely point towards that food being processed.
