To be fair, the study isn’t about butter, it’s about the flavouring agent used for that atrocious “golden topping” that renders movie-house popcorn inedible.
Amen to that! Every time I get that crappy “buttered” popcorn at the movies I curse the day they took the real butter from us “for our own good”. I just KNOW there is something vile and way worse than butter in that golden horror they use to “flavor” movie popcorn. I knew there was something to worry about there, as you feel sick after eating it.
