Right … but it’s not unreasonable to buy your kid microwave popcorn unless you know it’s harmful which one would assume is not the case since you can get it in the supermarket. So like, the people who were included in the study were obviously consuming the popcorn in the absence of the study.

It's not reasonable to buy 7 packs a week though.

Supermarkets sell a lot of unhealthy food which will give you terrible results if you eat them everyday, so I don't think that's a good argument.
