It's no myth that sugar in high dosages is toxic to the human body! According to many reliable unbiased scientific based sources the average U.S. citizen is consuming 60+ lbs of ADDED sugar annually or about 20-22 teaspoons daily or about 18% of daily calories(depends on total daily caloric load). This data is based on ADDED sugar that is basically added to just about EVERY highly processed highly refined intensively packaged food - food like product. Several estimates push the average consumption of refined sugar up well above the 120 lbs per yr mark.
The toxicity level has been far surpassed in the average U.S. citizen's diet. According to many scientific circles it is causing, or at least correlated with increases in illness and disease, lack of quality of life, and problematic imbalances in the human body.
