I read to the end. If "cook actual meals" is supposed to imply combining ingredients then you broke the rule of "only eat and drink things that have one ingredient". Otherwise I don't know what you're referring to.

I'm not confused by minimizing processing via home cooking, I'm confused by how your list was supposed to be relevant to the comment you replied to. That comment had a very specific objection.

(And yes, I see that the OP has now replied saying you can combine ingredients at home. But I think the skepticism toward the original phrasing was valid.)

You're playing dumb. We know this.

I'm not playing dumb. At this point I'm accusing them of saying the wrong thing.

"Buy things with one ingredient" is one idea. "Only eat things with one ingredient" is a very different and much more narrow idea.

And don't say it was obvious what they meant. I've seen people claim much wilder things about healthy eating than "don't combine ingredients".
