Whether or not junk food should be banned in schools is a personal opinion. Many scientists and doctors are for a junk food ban, but many are against taking all sweets and other junk foods out of the public school system.
Each year, childhood obesity becomes a bigger problem. According to KidsHealth, one in three American children is overweight or obese. However, removing all traces of junk food from schools may not help the problem.
Dr. Jane McCartney, a psychologist out of the U.K., explains that most people crave what they can't have, and when kids finally get to eat junk food, they eat more, causing them to gain weight. She says it's better to limit kids' food choices and allow them to have the occasional treat than to deprive them altogether.
