I've been told to never put potatoes or potato peelings down the disposal -- too much starch and it will ultimately clog it up (learnt that lesson the hard way in California). Other things to not put in disposal are anything stringy (celery, broccoli stems, asparagus, etc.); pasta (it swells as you add more water and clogs up the pipes); egg shells; large seeds such as peach and avocado pits. Ice is a good thing to put down every so often. So is the occasional lemon cut into quarters (makes the whole kitchen smell good).
