How to Read a Food Label

Tips for People with Chronic Kidney Disease (CKD)

If you have CKD, you may need to limit some nutrients in your diet such as sodium, phosphorus, or potassium. You should limit saturated and trans fats, too. Read the food label to help make healthy food choices for your kidneys.

  • Check the Nutrition Facts label for sodium.
  • Check the ingredient list for added phosphorus and potassium.
  • Look for claims on the label, like “low saturated fat” or “sodium free.”

What Should I Look for on the Nutrition Facts Label?

Look for sodium on the Nutrition Facts label. Some Nutrition Facts labels will list phosphorus and potassium, too, but they do not have to.

What Should I Look for on the Ingredient List?

  • Look for phosphorus, or for words with PHOS, on the ingredient list. Many packaged foods have phosphorus. Choose a different food when the ingredient list has PHOS on the label.

  • Look for potassium on the ingredient list. For example, potassium chloride can be used in place of salt in some packaged foods, like canned soups and tomato products. Limit foods with potassium on the ingredient list.
