In 2018 The University of Hertfordshire carried out a study to investigate young people’s access to food and drink during the school day, looking at what is sold in shops and outlets outside of school, as well as the food and drink they purchase within school too. The food served in schools is regulated but there is currently no regulation on the food and drinks available outside of school.The aim was to explore the type of shops and their marketing promotions and why young people choose to purchase and eat certain foods or drinks. We wanted to involve young people in this study to move beyond what other studies have revealed about food and drink purchased during the school day by secondary school pupils.
