Read the text below.
A   new study by the researchers from Columbia University, Harvard, and   University of Vermont shows that soda may cause young children to become aggressive.  
The   researchers studied around 3,000 children aged five and asked the mothers to   report their child's soda consumption. Mothers also accomplished a checklist on their child’s behavior in   the last two months to measure attention and aggression. The researchers also   asked mothers how many servings of soda their children drank per day.  
Overall,   43% of the kids drank at least one soda per day and 4% drank four or more   servings. Dr. Shakira Suglia, epidemiologist at the Mailman School of Public   Health, also said that the more soda a child drinks per day, the more   aggressive he or she becomes. 
Compared   with children who did not consume any soda, those who had four or more soda a   day were over twice as likely to be aggressive. Being aggressive involves   destroying other people's belongings, physically attacking others, and engaging   into fights. 
This   research agrees with previous studies saying that adolescents were more aggressive toward others and more likely to   hurt themselves the more soda they drank.  
Given   the results, the researchers clarified that the relationship between drinking   soda and aggression is yet to be proven.    Suglia also added that soda contains caffeine, a mild stimulant that may contribute to a child’s aggressive   behavior.
