I think that's a misreading of the chart and also why this chart is silly.
Countries like the US specialize because they exist in a world of widespread trade, not because they can't grow the foods that are imported.
Under autarky, farmers would face very different market incentives and would grow very different things.

This is just a cool thought experiment. In a real-life scenario where every country had to grow its own food, people would be starving everywhere—and it definitely wouldn't be because they're missing a food group.
