Mountain Dew Mind
Dentists have a name for the condition they see in kids who drink too much Mountain Dew. They wind up with a "Mountain Dew Mouth," full of cavities caused by the drink's excessive sugar levels. "Mountain Dew Mind" may be the next medical condition that gets named after the stuff. An ingredient called brominated vegetable oil, or BVO, added to prevent the flavoring from separating from the drink, is an industrial chemical used as a flame retardant in plastics. Also found in other citrus-based soft drinks and sports drinks, the chemical has been known to cause memory loss and nerve disorders when consumed in large quantities. Researchers also suspect that, like brominated flame retardants used in furniture foam, the chemical builds up in body fat, possibly causing behavioral problems, infertility, and lesions on heart muscles over time.
