Sugar linked with mental problems

Sugar has been linked with mental problems, which naturally means that we'll all go out and treat the issue with lots of extra drugs. Change the diet? Use common sense? As seen in this report.

Oslo teens who drank the most sugary soft drinks also had more mental health problems such as hyperactivity and distress, Norwegian researchers reported on Thursday.

Their study of more than 5,000 Norwegian 15- and 16-year-olds showed a clear and direct association between soft drink intake and hyperactivity, and a more complex link with other mental and behavioral disorders.

They surveyed the students, asking them how many fizzy soft drinks with sugar they had a day, and then questions from a standard questionnaire used to assess mental health.

The teens who reported skipping breakfast and lunch were among the heaviest soft drink consumers, Dr. Lars Lien and colleagues at the University of Oslo found.

"There was a strong association between soft drink consumption and mental health problems among Oslo 10th graders," they wrote in their report, published in the American Journal of Public Health.

"This association remained significant after adjustment for social, behavioral and food-related disorders."

Most of the students said they drank anywhere between one and six servings of soft drinks per week.

For hyperactivity, there was a direct linear relationship -- the more sodas a teen drank, the most symptoms of hyperactivity he or she had.

The worst problems were seen in boys and girls who drank four or more soft drinks a day. Ten percent of the boys and 2 percent of the girls drank this much.

The researchers said it was possible that other substances in the soft drinks, such as caffeine, were to blame for the symptoms, and they did not check other possible sources of refined sugar in the children's diets.

But they said many of the teens were clearly drinking too many sugary drinks. Norway's recommended intake is 10 percent of the day's total calories from sugar and the researchers said at least a quarter of the boys were getting this much from soft drinks alone.

"One simple and effective measure to reduce soft drink consumption in this age group would be to remove soft drink machines from schools and other public places where adolescents gather," they wrote.
