Lost in the desert?

A Boston University professor recently did a survey of the city's neighborhoods and concluded that, "There are areas around Boston that can legitimately be called food deserts," and he named Mattapan and East Boston as fitting that profile.

Dr. John Cook, according to an article in an alternative newspaper called The Weekly Dig, believes that some neighborhoods don't have easy access to healthy foods. As a result, Cook says, the residents -- usually working class or poor -- buy cheap food, which is usually the least healthy, from convenience stores.
