"Whole foods" is really vague, so I'm not sure how you would back up that statement.
This research is an indictment of how we make poor people eat.
It's the same bad logic behind fancy bottled water from distant springs. At one time, doctors prescribed such things, but it's not that the water from those springs had health-enhancing properties, it's that the tap water back home was fouled in the days before the Germ Theory of Disease.
