I don't know of a 24-70mm true Macro lens of any brand, if by "macro" we mean a lens that provides a maximum reproduction ratio of 1:1. Some lenses have "macro" in their title are just normal lenses which have a close-focus setting, such as the AF 24-85mm f/2.8-4D Nikkor. Nikon distinguishes its true macro lenses with the term "Micro"; they mostly go to 1:1 or close to it - the 24-85mm D goes to about 1:2.
But - as mentioned above - I'm not sure that a true macro lens is necessary for food shots, though to be fair they are usually better corrected for close-up work that normal lenses. If you did go for a macro lens, then as John-Erik says you could maybe consider one of the PC-E Nikkors. These have a tilt and shift facility that allows you to alter the shape and angle of the plane of sharpness, and makes it easier to get all of a plate of food into focus - if that's what you want. They go to 1:2, but that should be plenty
