Asda cut staff canteens from some 200 stores two years ago. It replaced them with fridges and microwaves as well as hot drinks machines.
Asda said it had launched a consultation into 5,000 roles, but stressed that this number would not translate to outright redundancies as staff could be redeployed.
Other areas under consultation include create-your-own pizza stands, which have not been widely used in Asda stores as customers prefer to buy pre-prepared. Photo centres could be closed or sold to a third party, George desks could be removed and Pharmacy hours could be cut.
A spokesman said that the consulation comes after a tough 2015.

“These proposals are designed to make our stores easier to shop in and be more effective in delivering the low prices, quality and good value which customers tell us they want,” the spokesman said.
On Monday, Asda announced 200 job loses at head offices in Leeds and Lutterworth.
