      Eating Well on a CKD Diet

      Share:
      veggies_image

      When you’re living with chronic kidney disease (CKD), what you eat and drink—and how much—is important and you'll want to start eating a kidney-friendly diet. Someone in the early stages of kidney disease may have different dietary needs than someone in the later stages. Talking to your doctor or renal dietitian will help you learn exactly what to eat and drink and why. Eating well and following a chronic kidney disease diet is key to keeping your kidneys working as long as possible.

      Learn to read and understand nutrition labels

      It’s important for people living with CKD to understand how to read nutrition labels. In addition to keeping an eye on certain nutrients, pay close attention to serving size. Be aware that the serving size listed may not match how much you actually expect to eat.

      When reading nutrition labels, the % daily value (DV) tells you how much a serving of food contributes to a daily diet (based on a diet of 2,000 calories). Try sticking to the following % daily values for each serving:

      • Dietary fiber—more than 10% DV
      • Saturated fat—less than 10% DV
      • Trans fat—none
      • Sodium—less than 10% DV
      • Added sugars—less than 10% DV
      nutritional info label

      What is a CKD diet and how is it different?

      Although a kidney-friendly diet follows many of the same basic ideas of a regular healthy diet, people living with CKD may also need to watch or limit certain foods. When your kidneys aren’t functioning at 100 percent, waste and fluid can build up in the body, causing health problems. Eating well can help your kidneys continue to function and keep you feeling your best.

      People with kidney disease may need to limit their intake of:

      • Sodium
      • Potassium
      • Phosphorus
      • Protein
      • Fluids

      In order to feel your healthiest, your individual needs may change if kidney disease progresses. Your doctor or dietitian may recommend dietary changes based on the results of your blood tests. If you already follow a certain diet for diabetes, high blood pressure, or other heart conditions, continue following those dietary recommendations as well.

      Lighten up on protein

      Your body uses protein to build and repair muscle. When you’re living with CKD, your doctor may suggest cutting back on how much protein you eat because of its effect on your kidneys. While protein is an important building block for a healthy body, it creates a waste called urea. With CKD, your body has trouble removing urea, which can make you feel tired and lose your appetite. Some people may also experience "ammonia breath," or have a metallic taste in their mouth, while their body works to remove excess urea. 

      Choose healthier proteins

      When you’re choosing proteins, it’s a good idea to avoid processed or fast foods. Instead, choose plant-based options or fresh, lean animal proteins. Watch your portion sizes and how often you eat protein-rich foods, especially if your doctor has discussed reducing your protein intake to protect your kidneys. If you’re unsure of how much protein you should eat, ask your doctor or renal dietitian for help.

      Some healthy protein choices to consider include:

      icon_plantbased
      Plant-based proteins:
      • Soy, tofu
      • Beans
      • Seeds
      • Lentils
      • Whole wheat
      • Nuts
      • Peanut butter
      • Brown rice
      • Peas
      • Green beans
      • Chickpeas
      icon_fish_lagoon
      Animal-based proteins:
      • Chicken
      • Turkey
      • Fish
      • Shellfish
      • Beef
      • Pork
      • Eggs
      • Dairy & fresh cheese

      Knowing how much protein is too much—or too little

      If your kidney function is less than 25% or stage 4 of CKD, you may be instructed to cut back on red meat, poultry, fish, and dairy since they contain high levels of protein. However, it’s important to understand that protein is still essential for all bodily functions, so follow your doctor or dietitian’s exact recommended protein intake.

      CONSIDER PLANT-BASED PROTEINS

      Plants have protein, too! Plantproteins are a great way tobuild and maintain musclewhile putting less stress onyour kidneys.

      Limit your sodium

      Healthy kidneys help control how much sodium is in your body. When your kidneys are not working their best, too much sodium can build up, causing swelling, high blood pressure, and stress on your heart. People living with CKD may need to limit their sodium and salt intake on a kidney diet. Talk to your doctor or renal dietitian about how much sodium you can consume each day. You can also try these tips and tricks to manage your levels.
      icon_fresh
      • Choose fresh foods—natural foods like fresh fruits and vegetables are great low-sodium choices because they contain less sodium compared to processed and fast foods.
      icon_foodlabel
      • Read food labels closely—foods with a % Daily Value of less than 10% for sodium are good options. Watch out for “reduced sodium” or “light in sodium” options, as these can still be high in sodium or potassium.
      icon_seasoning
      • Stick to salt-free seasonings—fresh or dried herbs, spices, and salt-free seasonings can still pack tons of flavor without the need for lots of sodium that can be hard on your kidneys.

      Balancing potassium for your heart

      Potassium is an important mineral that helps regulate your heart rhythm. When you’re on a CKD diet, your kidneys may have trouble keeping your potassium levels balanced. When your level is too high or too low, it can cause an irregular heartbeat or, in some cases, a heart attack.

      Portion control helps you manage your potassium levels. A portion is generally one half cup. Remember, eating more than one portion can turn a lower-potassium food into a high-potassium one—simply because of the amount you’re eating.

      Keeping phosphorus levels in check

      Phosphorus works with calcium to build strong bones and keep other parts of your body healthy. When your kidneys can no longer keep your phosphorus at the right level, it builds up. At this point, phosphorus becomes harmful to your body. High-phosphorus levels cause:

      • Increased risk of hip fractures
      • Increased risk of cardiovascular disease, which is a disease of the heart and blood vessels

      All phosphorus is not created equal. Chemically added phosphorus is absorbed more than naturally occurring phosphorus. Look for "PHOS" in food labels and try to steer clear of them!

      Measuring your fluid intake

      People living with CKD often need to limit their fluids. While water, tea, and anything you’re drinking out of a cup are obviously fluids, there are also some foods that contain enough liquid to be considered fluids, such as:

      • Soup
      • Ice cream, sherbet, sorbet
      • Nutritional drinks and smoothies
      • Gelatin (Jell-O®)
      • Ice cubes or ice chips

      Tip: Foods that melt or are liquid at room temperature are considered fluids.

      If your doctor has talked to you about limiting your fluids as part of a kidney disease diet, keeping track of your daily fluid intake is a good idea.

      Questions about what to eat? Talk to your doctor

      When it comes to a CKD diet plan, your doctor and renal dietitian are the best resources for providing the right dietary information for your unique needs. Speak up and ask questions so you can make your best choices.
