Hi, sissieann. The info on the site you mentioned I also have found not to be accurate. There are two very good websites I do trust, though. One is Self which lists the nutrients in a lot of foods, including potassium, sodium and phosphorus on their nutrition data page and another is my food data (no spaces) with a search tool. As a new member I'm not supposed to post links or URLs but Rosemarya might be able to post them again if you don't find them in this thread.
