Previously, I reported that a Tufts University researcher found that soda and sweet drinks are the biggest source of of calories for most Americans.
Another research paper (or "Invited Commentary" titled "Are soft drinks a scapegoat for childhood obesity?" in the May Journal of Pediatrics) revealed that U.S. adolescents swig down, on average, nearly two 12-ounce servings per day or the equivalent of 20 teaspoons of sugar and 300 calories.
But a quarter of all teens drink even more -- chugging as many as four servings of sugary drinks a day or 40 teaspoons of sugar and 600 calories.
They also found that "sweetened soft drinks amount to 40% of all added sugars in a child's diet and with the addition of fruit drinks, more than 50%."
