Over the past several decades, American consumption of carbonated soft drinks (CSDs) has increased dramatically. In 1947, Americans consumed on average two soft drinks per week.s By 1996, they consumed on average approximately two soft drinks per day. As a result, the CSD industry is, as of 2007, a $72 billion a year industry. There is a dark side to all of this consumption. Numerous studies link consumption of CSDs to various health problems,' including: heart disease, obesity, osteoporosis, and dental harm, especially dental erosion. The main culprits causing the dental harm are not the cola CSDs but rather the non-cola drinks such as Mountain Dew. Mountain Dew's effect on teeth even has a name: "Mountain Dew Mouth," and the effect is devastating.
