University unions say they are having to step in to help students cope with the rising costs of food.
Free breakfasts, community kitchens, food pantries and vouchers are among measures introduced in some cities, with others looking at expanding help.
The National Union of Students (NUS) says its research suggests one in three survives on £50 or less a month.
Both the English and Welsh governments said they had increased funds to aid hard-up students.
BBC Newsbeat went to Swansea University, where the student union has been trialling weekly free breakfasts including tea, coffee, toast and croissants.
