Soft Drinks Set Kids Off.
Norway has the highest rate of soft drink consumption in the world. Bar none.
As Christensen 1993 underlined, this could be related to Norway's high latitude and the severity of Seasonal Affective Disorder (SAD) at such a latitude.
This study compared the rates of behavioral issues to the amount of soft drinks consumed by over 5,500 Norwegian 10th graders. It found that those who consumed large amounts of soft drinks tended to have the most difficulty in school. Interestingly, those who consumed no soft drinks had more behavioral issues than those who consumed moderate amounts!
This finding is interesting in light of recent work suggesting that the high levels of fructose found in soft drinks may be contributing to higher-than-usual rates of diabetes in children today. Fructose is processed differently by the liver than glucose and sucrose, table sugar. High amounts of fructose are unnatural for the body and may be upsetting the liver's ability to properly metabolize it leading to obesity, Syndrome X and diabetes, according to this theory. And as we'll see shortly, there's a growing body of opinion suggesting that many cases of severe depression are a type of Syndrome X of the brain.
