Ormiston Victory Academy in Costessey is one of 30 secondary schools across Britain which are trialling the use of healthy vending machines.
The scheme is being run by the British Heart Foundation, selling 'Heart Healthy' snacks and drinks.
The Victory Academy school council was actively involved in the market research to choose suitable items for the machines.
The machine sells pure fruit juice, milk, dried fruit, Nutri-grain and Special K cereal bars and healthy sandwiches and rolls.
A school spokesman said: 'A small group of students worked after school with art and design and technology teachers to design Victory branding for the machines.
'The popularity of the machines - selling about �200 a week on average - is evident from the first month's sales figures with students encouraged to continue to suggest new lines.'
The project will form the basis of coursework for students in food technology and business studies.
