I'm surprised this is a new idea. Don't a lot of UK residents vacation in Spain and Portugal? Wouldn't most people already know that the food cultures there tend to be based on fresh local home-made foods with a lot less industrial crap? I knew that just from Portuguese immigrants I knew plus my brother's trip to Spain and how he crowed about the food (he's slim and health-conscious.)

This advice is a bit of a nothing-burger for me. You can pick any ethnicity, focus on its local fresh food that everyone's great-grandmas would have made, and you'll probably be way better off than modern SAD convenience eating.

I also question all of those "(country x) consumes twice as much (food) as (country y)" stats, because aren't those based on production and sales, not necessarily human consumption? Ie, they might be ignoring waste.
