A recent study published in Injury Prevention reported that violent tendency in teens may be linked to soft drink consumption.
The study included 2725 ninth- to twelfth-grade Boston high school students.
Although there was not a direct cause-and-effect relationship, the study showed that teens who consume five 12-ounce, non-diet soft drinks a week were more likely to be aggressive and violent, including a higher instance of violence against others and carrying weapons.
The study reported that “direct-cause-and effect relationship between soft drink consumption and aggression is one possibility…various ingredients, including carbonated water, high fructose corn syrup, aspartame, sodium benzoate, phosphoric or citric acid, and often caffeine…might affect behaviour.”
There are critics of the study, citing incomplete information and the fact that junk food diets and alcohol can also be linked to the same behavior.
