Somewhat milder climates (France, Spain, Portugal) grew foods that had slightly longer growing seasons or needed slightly longer "cool" seasons.

Warmer climates (Mediterranean) grew foods that required longer, warmer growing seasons.

They sure are trying to make it sound like there's got to be one ideal diet for everyone on the planet, when realistically there isn't even one specific assortment of foods that can be grown everywhere.

Every culture historically ate what was available locally and only what was in season, unless it could be stored using primitive preservation techniques for the winter.

We're just a mess these days because we can get every type of food from all over the globe, including tons of highly processed carbs.
