I did say “controversially” and “potentially” :)
I think it was the WHO who mentioned it last year, but it keeps cropping up each year from various university studies - of course I’ll have only ever read the news reports of those studies.
I absolutely agree though, I’d be highly suspicious of sugar company (or high-fructose-syrup) lobbying.
Personally my preference is for “things to just be less sweet” (like why does some bread or soup have sugar in now?!?), though I suspect it’s a bit of a minority opinion :)
