It turns out measuring aspartame consumption by country is not simple and that there aren't good sets of equivalent studies across regions to draw from. I browsed some papers in the National Library of Medicine[0] and it seems like, at least as recent as a decade ago, it's generally accepted the USA has a higher intake than the rest of the globe, by 15-25% per capita, but it's hard to know for sure.

I agree there should be an epidemiological case for a link, but alternatively maybe the link is that there is no strong link to cancer.

Everything in moderation, as they say.

0: search "aspartame intake", I can't easily cite anything right now.
