I doubt this.

True. Simopoulos suggests a daily intake of EPA+DHA equal to
about a gram, I think. To get the equivalent in ALA would
require much more. But this is based on expected w-6 intake. If
overall PUFA intake is low, I suppose one could get away with
less w-3.

Yes, but most nuts have very poor w-6:w-3 ratios. Hazels, for
example, have a ratio of 39:1. Brazil nuts have a ratio of 383:1!
Much as I like nuts, I have to concede that as a general thing
they are too high in w-6 fats. The fact that many people find
that nut consumption promotes acne is probably a result of the
pro-inflammatory nature of the fat ratios.

I've never eaten either one, but according to USDA the chia seeds
have an astonishingly favorable ratio of .8.
