I'd combine Tomás Robert's solutions:

(defvar my-codes
    '((1 . bread)
      (2 . cheese)
      (3 . wine))) 

(defun replace-all ()
  (interactive)
  (dolist (x my-codes)
    (replace-string (number-to-string (car x))
                    (symbol-name (cdr x)))))

After which M-x replace-all
should do it
