Hi @nosurgery . I'm a 73 yo retired nurse, small world, eh? Although I don't have diverticulitis (yet, knock on wood) I do have divertiiculosis, which many people my age do have. A perforated bowel and peritonitis are no-joke risks so I see why you have to be so careful. At the same time, having only one kidney (me, too) means being careful about that as well. Although I've consulted with a renal dietitian I've found much better, more up-to-the-minute info at two websites. As a new member I can't post URLs but I can tell you that one is called self (capital S) nutrition data and another is my food data (no spaces) dot com; both list complete nutritional values of various foods, including potassium, phosphorus, fiber, and sodium. Maybe you'd like to google them? Meanwhile, good luck balancing diverticulitis diet with renal diet.
