This event included promotions for a new soft drink, a new energy bar, and a new burger restaurant. The organizers of the event encouraged students to buy the pineapple-flavored drink. However, in a recent interview with Education Live, Jennifer Robinson, a senior nutritionist at St. Bartholomew Hospital, disapproved the promotional strategy. She claimed that eating junk food and consuming energy drinks "severely hampers brain development." As a nutritionist, Robinson strives to promote healthy eating habits. She added, "Eating junk food is a waste of money. Consumption of junk food drastically impacts a child's mental and physical development. It is important that schools make an effort to educate their kids about healthy eating." Pomegranate Children's Organization created a presentation highlighting the benefits of consuming the new cola drink. Mr. Justin Wood, senior spokesperson for the organization, stated that they "conducted a lot of research before sharing the presentation with the public." In response to this claim, Mr. Edward Jones, the director of the Norfalk Nutrition Center, responded by claiming that, "consuming junk food has more cons than pros. He stated that excessive consumption of junk food can affect students' concentration levels and make them feel lazy. This can lead to their poor performance in class."3.
