While you are pointing out correct things, you are missing the forest for the trees.

Here is a better article: https://www.reuters.com/business/healthcare-pharmaceuticals/whos-cancer-research-agency-say-aspartame-sweetener-possible-carcinogen-sources-2023-06-29/

The IARC makes its carcinogenic categorizations mutually exclusive from dosing. If a substance is known to be carcinogenic at unrealistic amounts, it will still be labeled as carcinogenic. They don’t’ bring the human dosing element into play.

There is another WHO organization called the JEFCA that does actual food safety, with the context of a human being.

It’s not this straight forward. I read the reuters article about this that goes into more detail.

But basically, IARC is only looking at if the substance can be carcinogenic, regardless of the quantity it takes for it to be harmful to humans.

There is another organization, called JECFA that is specifically for advice for individuals. This is where “food regulations” would come from.

The JECFA is set to show off their findings at the same time as IARC is gonna make their announcement. I feel like some of you guys are jumping the gun here due to the title of the articles coming out.
