Do I need to follow a special diet at every stage of CKD?

Not always. Early stages may only require lower sodium and good blood pressure control. As CKD advances, your provider may recommend changes in potassium, phosphorus, or protein based on your labs.

Is drinking more water good for my kidneys?

Staying well hydrated is helpful for most people, but patients with advanced CKD, heart failure, or on dialysis often need to limit fluids. Always ask your nephrologist what's right for you.

Can I still take ibuprofen or naproxen?

NSAIDs can reduce blood flow to the kidneys and worsen kidney function. Most CKD patients should avoid them and use acetaminophen (Tylenol) for pain — please confirm with your provider.

Where can I learn more from trusted sources?

The National Kidney Foundation (kidney.org) and the American Association of Kidney Patients (aakp.org) offer excellent free patient education materials.

Patient Education

Understanding your kidneys, and how to care for them.

Knowledge is one of the most powerful tools for living well with kidney disease. Below are trusted resources on common kidney conditions and the CKD-friendly diet.

About Kidney Conditions

Learn the basics of common kidney conditions.

Understanding Chronic Kidney Disease (CKD)

CKD means your kidneys are damaged and cannot filter blood as well as they should. It is staged 1–5 based on how well your kidneys are working (eGFR). Early stages often have no symptoms, which is why regular labs and blood pressure checks matter. With the right care, many people with CKD live full, active lives.

Blood Pressure & Your Kidneys

High blood pressure is both a cause and a consequence of kidney disease. Keeping your blood pressure at goal — often less than 130/80 mmHg if recommended by your provider — is one of the most important ways to protect your kidneys.

Diabetes & Kidney Health

Diabetes is the leading cause of kidney failure in the U.S. Controlling blood sugar, blood pressure, and cholesterol — along with certain kidney-protective medications — can slow or prevent damage.

Medications to Use With Caution

Some over-the-counter medications can harm the kidneys, especially NSAIDs (ibuprofen, naproxen) and certain herbal supplements. Always tell your pharmacist and providers that you have kidney disease before starting anything new.

End Stage Renal Disease

Advanced chronic kidney disease means your kidneys are losing much of their ability to remove waste and extra fluid from your body. Learn about symptoms, treatment options, dialysis and transplant planning, and the steps you can take now to protect your health and prepare for the future.

Dietary Education for CKD

Eating well with chronic kidney disease.

A kidney-friendly diet helps slow CKD progression and reduce symptoms. The right targets depend on your stage, labs, and other conditions — always confirm with your nephrologist or a renal dietitian.

Sodium: aim for less than 2,000 mg per day

Cook at home when possible and use herbs, citrus, garlic, and vinegar instead of salt.
Read labels — look for 'low sodium' (140 mg or less per serving).
Limit processed foods: deli meats, canned soups, frozen dinners, fast food, and salty snacks.
Rinse canned beans and vegetables to lower sodium content.

Potassium: balance based on your labs

If your potassium runs high, limit oranges, bananas, potatoes, tomatoes, avocados, and melons.
Lower-potassium choices include apples, berries, grapes, cabbage, green beans, and white rice.
Boiling and draining potatoes and vegetables ("leaching") reduces potassium content.
Avoid salt substitutes containing potassium chloride (such as NoSalt or Lite Salt).

Phosphorus: protect your bones and heart

Limit dark colas, processed cheese, and packaged foods with 'PHOS' on the label (added phosphorus is absorbed quickly).
Choose smaller portions of dairy, nuts, and whole-grain breads if advised.
Take phosphorus binders with meals exactly as prescribed.

Protein: the right amount for your stage

Earlier CKD stages: moderate, high-quality protein helps slow progression.
Dialysis patients: usually need MORE protein to stay strong — your team will guide you.
Good sources include eggs, fish, poultry, and lean meats in portion sizes recommended for you.

Fluids: ask your provider what's right for you

Most people with early CKD do not need to restrict fluids.
Patients on dialysis or with swelling may need a daily fluid limit.
Watch for swelling in the ankles, shortness of breath, or sudden weight gain and report them.
