Unless you really need A DSLR for other reasons, a good quality point and shoot will do the job for food porn photos at a much lower cost than a DSLR. I have both a Minolta DSLR, with a small fortune in extra lens, filters, and accessories plus an Olympus point and shoot. The DSLR is great for action shots and long telephoto lens work like capturing eclipse of the moon and wildlife. For simple shots, with no action involved, my Olympus does a decent job. If you plan on taking your photography beyond just food porn shots, then I'd go with a DSLR otherwise a good point and shoot would probably do just fine.
