I read somewhere that the antioxidant power of olive oil greatly diminishes with time. I suspect the stuff we have in the US isn't nearly as good as what people local to olive trees get.

Exactly, when you drink good olive oil, it should burn your throat. Over time the healthful chemicals that do that degrade. I have read articles in the past that say that most of the time EVOO from the EU is done by the time it gets to the US (and that's assuming it's not counterfeit). So US made or better yet, local EVOO is likely a much better product.
