the big problem isn't that nuts are awesome and we're missing out, the really, really big problem is that most antidepressants aren't that great, at least in big trials.

My understanding is that severe depression responds to antidepressants, but milder cases don't and they often have more adverse effects than benefits, anyway.

Antidepressants are prescribed like candy in the US and some other places. That results in people who don't need them taking them and then declaring "the pills don't work!" and "I was better off without the pills!," etc.

I take a high dose of wellbutrin, personally. My depression--which often involves psychotic features--has responded nicely, with no major adverse effects. I also take a lot of supplements, which probably help reduce+prevent adverse effects, if nothing else. That's the other point; healthy eating, supplements, yoga, etc. can be done with Rx treatments, if needed. It doesn't need to be an either/or situation.
