How American Meals Came Down To 'Three Squares'

It was a French gastronome who coined the now famous phrase, "we are what we eat." In her new book, Abigail Carroll adds to that notion by glancing through history to show that we are also how, when and where we eat. She writes that our shared history explains a lot about American eating habits, including the idea of three square meals a day, which is a relatively recent social construct. We didn't always eat this way, so why do we now?
