Calories are not nutrition. Food loaded with sugar and preservatives is much cheaper than healthy foods, and it also happens to be more readily available. Many poor neighborhoods don't have grocery stores where one can purchase fresh fruit and vegetables, but they do have convenience stores where you can buy all the candybars and junk food you can eat... at a considerable markup.
