This is a fascinating article in terms of the effect of CO2 on plants... but I have a tremendously hard time believing it's affected diets in the first world.

The level of carbs and nutrients in your diet would seem to determined by your dietary choices by an overwhelmingly larger degree. Are you eating french fries or kale?

Does it really matter if my zucchini is slightly less nutritious when I could just eat broccoli rabe instead? Or that my green beans have a trace of carbs when I'm eating a potato on the side? In supermarkets today we've never had greater choice or variety, especially in winter, at least if you're willing to pay for it -- but even in terms of paying for it, food today is the cheapest it's ever been.
