Food! It's a vital part of our culture and our family traditions. Meals are something we look forward to each day. Food is love, comfort, and memories.

We all have favorite foods, things we don't like, foods we learned to like over time, and foods we used to eat but don't any more. We may have pounds to lose or weight to gain. We may love to cook or never set foot in a kitchen. Any way we look at it, food is a big part of life.

A chronic illness like kidney failure can require changes in your eating and drinking habits. These lifestyle changes can be hard to understand—and even harder to make! If you have kidney failure—with or without diabetes, meal planning may even seem almost impossible. As one patient said:

From what I have read, we are supposed to buy something to eat, throw it in the trash, and eat the box that it came in—everything else is bad for us.

Don't worry—we can help! In this module, we'll try to make it clearer for you. Stick with us, and we'll teach you about food and drinks...and give you practical tips to make your life easier. At the end of this module, we'll give you 2 weeks of sample menus to help you plan.

Our goal is to show you how you can take charge of your food and fluids. If you do, you can feel better, improve your lab results, and have a better quality of life.

Here's a sneak preview of what we'll be covering in this program:

  • Nutrition basics
  • Getting the right amounts of key nutrients
  • Planning meals and eating out
  • Strategies for lifestyle changes

So, let's get started.

Take the Kidney Quiz!

You'll have a better sense of how much you've learned from this module if you take our quick kidney quiz. It's just 10 questions. How about it?

What if I Have CKD but Not Kidney Failure?

This module is designed to help you learn about meal planning for peritoneal dialysis (PD) or standard in-center hemodialysis (HD)—with or without diabetes. Other types of dialysis, like daily or nocturnal HD, have a near-normal diet.

If you have an early stage of chronic kidney disease (CKD), talk to your doctor about what to eat—and what to avoid. He or she may refer you to a dietitian, who can help you with a meal plan. This meal plan might include:

  • Limiting protein. Some research shows that you can slow the rate of some CKD by eating less protein. Another reason to eat less protein is avoiding a build-up of urea. Other studies suggest limiting protein may be risky if it leads to malnutrition. Talk to your doctor about what's best for you.
  • Drinking more fluids. Your doctor may want you to drink plenty of fluids to help flush out wastes. If you have a history of kidney stones, drinking more water is recommended.
  • Taking phosphate binders. Having too much phosphorus can harm your bones. You may be asked to take phosphate binders—drugs that keep extra phosphorus out of your blood by binding with it and removing it in your stool.
  • Eating less phosphorus. You cannot avoid all foods with phosphorus, but it is good to learn about how to eat less phosphorus.
  • Limiting salt. If your blood pressure is high, your doctor may want you to eat less salt to help keep your kidneys working longer.

Your doctor and a renal (kidney) dietitian can help you sort out your meal planning. If you don't have a dietitian, your doctor may be able to refer you to one.

If you want to learn more about what your meal plans might be like when you are on dialysis, keep reading! We'll help you understand what to eat more of and what to eat less of if you choose PD or standard in-center HD.
