As the cost of food is generally high, and students have a lack of time between classes, it would be better if there were healthier food options in vending machines so that people can feel properly fueled between classes rather than having to rely on crisps or sweets, especially if they are based in a building without a cafe such as Wearside View, David Goldman or Media centre. 
 

the vending machines are temperature controlled so some fruit (such as oranges and apples) could be placed on the bottom row of the vending machine so that they do not get bruised when they are dispensed. This could also be used to provide a more budget friendly snack option as fruit is generally less expensive than sweets and snacks. 
 

in terms of drinks, electrolyte drinks could be offered in a wider variety and have less traditional pop in the machines so that people don't have to rely on fizzy drinks or drinks with high amounts of sugar and caffeine.
