Kidney-Friendly Diet for CKD

You need to have a kidney-friendly meal plan when you have chronic kidney disease. It is important to watch what you eat and drink to manage your chronic kidney disease and help you feel better.  The information in this section is for people who have kidney disease but are not on dialysis. This information should be used as a guide. Every person is different, so there is no one-size fits all diet plan for people with kidney disease.

The steps below will help you eat right as you manage your kidney disease. The first three steps (1-3) are important for all people with kidney disease. The last two steps (4-5) may become important as your kidney function declines.

The first steps to eating right

Step 1: Choose and prepare foods with less salt and sodium

Why? To help control your blood pressure. Your diet should contain less than 2,300 milligrams of sodium each day.

  • Buy fresh food often. Sodium (a part of salt) is added to many prepared or packaged foods you buy at the supermarket or at restaurants.
  • Cook foods from scratch instead of eating prepared foods, “fast” foods, frozen dinners, and canned foods that are higher in sodium. When you prepare your own food, you control what goes into it.
  • Use spices, herbs, and sodium-free seasonings in place of salt.
  • Check for sodium on the Nutrition Facts label of food packages. A Daily Value of 20 percent or more means the food is high in sodium.
  • Try lower-sodium versions of frozen dinners and other convenience foods.
  • Rinse canned vegetables, beans, meats, and fish with water before eating.

Look for food labels with words like sodium free or salt free; or low, reduced, or no salt or sodium; or unsalted or lightly salted.

Look for sodium on the food label. A food label showing a Percent Daily Value of 5% or less is low sodium. Also look for the amount of saturated and trans fats listed on the label.

Step 2: Eat the right amount and the right types of protein

Why? To help protect your kidneys. When your body uses protein, it produces waste. Your kidneys remove this waste. Eating more protein than you need may make your kidneys work harder.

  • Eat small portions of protein foods.
  • Protein is found in foods from plants and animals. Most people eat both types of protein. Talk to your dietitian about how to choose the right combination of protein foods for you.

Animal-protein foods:

  • Chicken
  • Fish
  • Meat
  • Eggs
  • Dairy

A cooked portion of chicken, fish, or meat is about 2 to 3 ounces or about the size of a deck of cards. A portion of dairy foods is ½ cup of milk or yogurt, or one slice of cheese.

Plant-protein foods:

  • Beans
  • Nuts
  • Grains

A portion of cooked beans is about ½ cup, and a portion of nuts is ¼ cup. A portion of bread is a single slice, and a portion of cooked rice or cooked noodles is ½ cup.

Step 3: Choose foods that are healthy for your heart

Why? To help keep fat from building up in your blood vessels, heart, and kidneys. To help keep fat from building up in your blood vessels, heart, and kidneys.

  • Grill, broil, bake, roast, or stir-fry foods, instead of deep frying.
  • Cook with nonstick cooking spray or a small amount of olive oil instead of butter.
  • Trim fat from meat and remove skin from poultry before eating.
  • Try to limit saturated and trans fats. Read the food label.

Heart-healthy foods:

  • Lean cuts of meat, such as loin or round
  • Poultry without the skin
  • Fish
  • Beans
  • Vegetables
  • Fruits
  • Low-fat or fat-free milk, yogurt, and cheese
