Imagine, just for a moment, you are a mother who cannot afford to regularly put enough food on the table. You rely on Supplemental Nutrition Assistance Program benefits, better known as food stamps, to purchase groceries each month. You are looking for orange juice. But orange juice can cost upward of $5 a gallon. Orange-colored sugar water, on the other hand, is less than $2 a gallon. So you might pick that up instead. In a few months, however, low-income New York City households that use food stamps may not have that option.
