Aggressive behavior in children linked to soda

Children who drink soda tend to score slightly higher on scales that measure aggressive behavior than those who don't drink the carbonated beverages, according to a new study.

The study's lead author cautioned, however, that the increase may not be noticeable for individual children and the researchers cannot prove soda caused the bad behavior.

"It's a little hard to interpret it. It's not quite clinically significant," Shakira Suglia, of Columbia University's Mailman School of Public Health in New York, says.
