Hey, I buy soft drinks for medicinal purposes. (One of my meds upsets my stomach - slightly de-fizzed ginger ale helps a ton. Ginger tea has too much bite for me.)
ETA: Given the calorie content of most junk food, technically it is also nutrition. Just not very good. But I knew kids in high school who would have a can of soda for breakfast because there wasn't anything at home to have for breakfast and soda keeps. Then the school district started doing breakfasts at the school.
