Diabetic Renal Diet: Care Instructions

Your Care Instructions

You may already be spreading carbohydrate throughout your daily meals to manage your diabetes. When you also have kidney disease, you need to avoid foods that make your kidneys worse. Keep your blood sugar and blood pressure as near normal as you can to reduce your chance of kidney failure.

Your doctor and dietitian will help you make an eating plan. You may need to limit salt, fluids, and protein. You also may need to limit minerals such as potassium and phosphorus. It takes planning, but there are plenty of tasty, healthy foods you can eat. Always talk with your doctor or dietitian before you make changes in your diet.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • Work with your doctor or dietitian to create a food plan that guides your daily food choices.
  • Do not skip meals or go for many hours without eating.
  • You can use margarine, mayonnaise, and oil to add calories to your diet for energy. The healthiest oils are olive, canola, and safflower oils.
  • Be safe with medicines. Take your medicines exactly as prescribed. Call your doctor or nurse call line if you think you are having a problem with your medicine. You will get more details on the specific medicines your doctor prescribes.
  • Do not take any other medicine without talking to your doctor first. This includes over-the-counter medicines, and natural health products such as vitamins and herbal products.
  • Check with your doctor about alcohol. Count it as part of your fluid allowance.

To get the right amount of protein

  • Ask your doctor or dietitian how much protein you can have each day. You need some protein to stay healthy.
  • Include all sources of protein in your daily protein count. Besides meat, poultry, and fish, protein is found in milk and milk products, beans, peas, lentils, nuts, seeds, tofu, fortified soy beverage, and eggs. Check for protein on the Nutrition Facts table found on packages of food such as bread and cereal.
  • Learn more about protein and your kidney diet.

To limit salt (sodium)

  • Do not add salt to your food. And look for "reduced salt" or "low sodium" on labels.
  • Do not use a salt substitute or lite salt unless your doctor says it is okay. (These products are high in potassium.)
  • Avoid or use very small amounts of condiments and marinades. These include soy sauce, fish sauce, and barbecue sauce. They are high in sodium.
  • Avoid salted pretzels, chips, and other salted snacks.
  • Check for sodium on the Nutrition Facts table to become more aware of the sodium content of foods. Foods that are high in sodium include soups; many canned foods; cured, smoked, or dried meats; and many packaged foods.

To control carbohydrate

  • Ask your dietitian how much carbohydrate you can have. Carbohydrate foods include:
    • Whole grain and refined breads and cereals, and some vegetables such as peas and beans.
    • Fruits, milk, and milk products (except cheese).
    • Candy, table sugar, and regular carbonated drinks.
  • Talk to your dietitian about how to manage eating sweets, including honey and sugar.

To limit fluids

  • Know how much fluid you can drink by asking your dietitian or doctor. Fill a pitcher with that amount of water every day. If you drink another fluid (such as coffee) that day, pour an equal amount out of the pitcher.
  • Foods that are liquid at room temperature count as fluids. These include ice, gelatin, ice pops, and ice cream.
  • Learn more about fluids and your kidney diet.

To limit potassium

  • Ask your healthcare provider how to change your diet to eat the amount of potassium that's right for you.
  • Fruits that are low in potassium include blueberries and raspberries.
  • Vegetables that are low in potassium include cucumbers and radishes.
  • Limit, or avoid high-potassium foods such as avocado, cooked greens (such as spinach, Swiss chard, and beet greens), and potatoes.
    • Tip to lower potassium: Peel potatoes and cut into small cubes or shred before boiling. Discard the water.
  • Avoid processed foods that have reduced salt. Many of these foods replace salt with potassium, always check the ingredient list.
  • Learn more about potassium and your kidney diet.

To limit phosphorus

  • Ask your healthcare provider how to change your diet to eat the amount of phosphorus that's right for you.
  • Follow your doctor's or dietitian's plan for your limit on milk and milk products in your diet.
  • Limit nuts, peanut butter, seeds, and legumes and pulses. If you follow a vegetarian or vegan eating style, a dietitian can help plan what works best for you.
  • Avoid processed meats like bacon and pepperoni, organ meats, salmon (canned with bones), and sardines.
  • Limit packaged foods and drinks with phosphate additives. This includes processed meats and cola. Your body absorbs phosphorus from additives more easily than phosphorus that is found naturally in food.
  • Avoid whole grains and whole wheat bread, bran breads or bran cereals. They are high in phosphorus.
  • Learn more about phosphorus and your kidney diet.
