"It takes less time to check a food label than it does to respond to a text message or check Facebook"

That's a pretty ridiculous counter. Multiply that by the dozens to hundreds of items a person buys in a single grocery trip, and you might have a valid comparison. It's true that this would be mostly a one time cost, as you would start to learn what is good and what is not, but the fact still stands that it is not as quick as checking a text message.
