Dietary modifications such as phosphorus and potassium restrictions are usually not necessary in the earlier stages of CKD, but this will vary person to person and depend on your lab values. You should speak with a Registered Dietitian. He or she will be able to work with you to customize a meal plan that will meet your specific needs, including your weight, health history, medications, activity level, lab values and level of kidney function.
