๐ Daily Nutritional Targets (Stage 3 CKD)
Protein
0.8-1.0 g/kg
Per day (based on body weight)
Example: 70kg person = 56-70g protein/day
Sodium
< 2000 mg
Per day
Aim for 1500-2000mg (less is better)
Potassium
2000-3000 mg
Per day (based on lab values)
Adjust based on blood K+ levels
Phosphorus
800-1000 mg
Per day
Lower is better for kidney health
Fluids
Individual
Based on urine output
Usually 1-2 liters/day unless restricted
Calories
30-35 cal/kg
Per day (maintain healthy weight)
Example: 70kg person = 2100-2450 cal/day

๐ก Important Tips & Guidelines
๐ณ Cooking Tips
- Leaching Potassium: Soak high-K vegetables in warm water for 2+ hours, then double-boil to reduce potassium by ~50%
- Season Without Salt: Use herbs (basil, oregano, thyme), spices (garlic powder, onion powder), lemon juice, vinegar
- Choose Fresh or Frozen: Avoid canned foods (high sodium). If using canned, rinse thoroughly
- Read Labels: Check for phosphate additives (anything with "phos" in the name)
๐ฝ๏ธ Eating Out Tips
- Request No Salt: Ask for food prepared without salt or sauce on the side
- Grilled is Better: Choose grilled, baked, or steamed instead of fried
- Skip the Extras: Avoid pickles, olives, cheese, bacon
- Portion Control: Ask for half portions or take leftovers home
๐ Important Reminders
- Work with a Dietitian: A renal dietitian can personalize your plan based on your labs
- Monitor Your Labs: Potassium, phosphorus, and creatinine levels guide your diet
- Medication Timing: Take phosphate binders with meals if prescribed
- Stay Consistent: Small daily choices add up to better kidney health
- Don't Overdo Protein: More protein = more kidney work. Stick to your target!
โ ๏ธ Watch Out For
- Salt Substitutes: Often contain potassium chloride - AVOID unless approved by doctor
- "Healthy" Foods: Avocado, quinoa, kale are high in potassium/phosphorus
- Supplements: Multivitamins often have too much phosphorus/potassium. Check first!
- Protein Powders: Often very high in phosphorus. Consult dietitian first
