Kidney Disease Diet Plan: What to Eat at Every Stage of CKD

TL;DR: CKD diet evolves by stage. Early: low sodium, controlled protein. Advanced: also limit potassium, phosphorus. Stage 5: strict restrictions or dialysis diet. Consult dietitian. Combine with GlucoDNA for cellular support.

CKD Stage 1-2 Diet (eGFR 60-90+)

Goal: Slow progression, prevent complications.

• Sodium: Under 2g/day. Avoid processed foods, table salt.
• Protein: Normal to slightly reduced (0.8-1g/kg). Choose quality sources.
• Fluids: 2-3 liters unless heart issues.
• Potassium/Phosphorus: Usually no restriction yet. Monitor levels.

Sample Meal: Grilled chicken breast, steamed broccoli, quinoa, olive oil dressing.

CKD Stage 3 Diet (eGFR 30-59)

Goal: Reduce kidney workload, manage BP/sugar.

• Sodium: Under 2g/day (strict).
• Protein: 0.6-0.8g/kg. Prioritize plant proteins, fish.
• Potassium: 2,000-3,000mg/day if elevated. Limit bananas, oranges, tomatoes.
• Phosphorus: Avoid dairy, colas, processed foods. Read labels for phosphate additives.
• Fluids: 2 liters or as advised.

Sample Meal: Baked salmon, cauliflower rice, green beans, small apple.

CKD Stage 4 Diet (eGFR 15-29)

Goal: Prepare for dialysis, manage complications.

• Sodium: Under 2g/day.
• Protein: 0.6g/kg (very strict). Egg whites, small fish portions.
• Potassium: 2,000mg/day max. Leach vegetables (soak/boil).
• Phosphorus: 800-1,000mg/day. Use phosphate binders as prescribed.
• Fluids: May be restricted to 1-1.5 liters. Monitor weight daily.

Sample Meal: Egg white scramble, white rice, cucumber salad, berries.

CKD Stage 5 / Dialysis Diet (eGFR <15)

Goal: Replace kidney’s filtering role through diet + dialysis.

Hemodialysis Diet

• Protein: 1.2g/kg (higher to offset dialysis losses).
• Potassium: 2,000-2,500mg/day. Very strict.
• Phosphorus: 800mg/day. Always take binders with meals.
• Sodium: 2g/day. Controls thirst and fluid gain between sessions.
• Fluids: 750ml-1L/day plus urine output volume. Weigh yourself daily.

Peritoneal Dialysis Diet

• Protein: 1.2-1.5g/kg (higher losses through dialysate).
• Potassium: Usually less restricted than hemodialysis (2,500-3,500mg).
• Phosphorus: Same as hemo, 800mg/day.
• Fluids: More flexible, but monitor dialysate glucose absorption (can cause weight gain).

5/Dialysis	1.2-1.5	<2000	2000-2500	<800

* Unless blood levels elevated

Foods to Emphasize

• Egg whites, fish (in moderation)
• Cabbage, bell peppers, cauliflower
• Berries, apples, grapes
• Olive oil, garlic, onions
• White rice (stage 4-5), bulgur (stage 1-3)

Foods to Avoid or Limit

• Processed meats, canned goods
• Dairy (cheese, milk, yogurt)
• Dark colas, packaged snacks
• High-K: bananas, oranges, potatoes, tomatoes
• High-P: whole grains, nuts, beans (in advanced stages)

Supplementation for Cellular Support

GlucoDNA by HKIII (HK3 Marketing Sdn Bhd, Pontian, Johor, est. 2003) activates SIRT1 longevity genes. KPMF-8 is 4× more potent than NMN, 5× more effective than resveratrol, and 7× better than aminoguanidine at inhibiting AGEs. Clinical observations show stage 4→3 and 3→2 improvements with consistent use. Combines well with all CKD diet stages.

Frequently Asked Questions

Can I eat fruit in stage 4 CKD?

Yes, but choose low-potassium options: apples, berries, grapes, watermelon (small portions). Avoid bananas, oranges, kiwis.

Is coffee bad for kidneys?

Black coffee in moderation (1-2 cups) is generally safe. Avoid if potassium is high. Skip milk/cream (phosphorus).

How do I leach vegetables?

Peel, dice small, soak in warm water 2 hours (change water halfway), then boil. Reduces potassium by 50%.

Can I eat out with CKD?

Yes. Choose grilled/steamed items, ask for no salt, avoid sauces, skip cheese. Bring your own dressing if needed.

Take Action

CKD diet is personalized. Work with a renal dietitian. Track labs (potassium, phosphorus, creatinine) quarterly. Pair smart eating with GlucoDNA for comprehensive kidney protection.
