Good point on observational studies being of limited use.
People who eat nuts may be less likely to eat chips or processed food in general.
So an observational study probably wouldn’t tell whether the nuts themselves have positive effects or not.
But it’s probably not a bad thing unless you’re allergic.
I think it’s fair to think of it in the context of, if you already struggle with depression and you enjoy eating nuts, this is just an excuse or a little nudge/reminder that it probably won’t hurt to do so and might have a minor positive effect. I think that’s useful information and we shouldn’t focus too heavily on whether we fully understand the science.
