Food Cops Cheer Over Rising Food Costs

"Last week's issue of TIME magazine featured an endorsement of America's rising grocery prices. Yes, an endorsement. Claiming that obesity is the residual price of affordable food, TIME reporter John Cloud concludes that 'it actually would be good if food cost a great deal more.' But growing grocery bills won't bring shrinking waistlines, because personal preferences drive dietary choices more directly than pocketbook concerns." Read on.

Not only this but, I have heard it argued many times, the poor in the U.S. are also overweight because they have less money with which to buy groceries, and therefore end up purchasing cheaper, less healthy, high-caloric and fat-laden food items.

Using this argument, will this not then be an unintended (and harmful) consequence that will affect an even larger segment of the population? Or am I just being too logical?
