£5 a week is not a lot but I would imagine it's possible for a student.
My wife and I have a food budget of £25 a week which includes food for us (and also to an extent the dog). With proper meal planning and budgeting it's definitely possible to make massive supermarket savings - we used to speand £40-50 a week.
