Something I once heard that I assume to be true is that, most seed oils aren't overtly bad for you (which doesn't mean that there aren't better options) so much as that they're often found in lots of high calorie, low nutrition foods that, when eating with any frequency, are pretty bad for you.

But believing this will make you fail group purity tests, and get you othered so it can't/mustn't be true 🙂
