High creatinine? 3 proteins you should eat and 3 you should never consume

3 Proteins You Can Eat (With High Creatinine)

These options are generally easier on the kidneys when portions are controlled and prepared simply.

1) White Fish (Hake, Tilapia, Cod)

  • High-quality protein with a favorable amino acid profile
  • Typically creates a lower metabolic burden than red meat
  • Can provide omega-3s, which support an anti-inflammatory diet

Suggested portion: 90–100 g, 2–3 times per week

2) Egg Whites

  • Mostly pure protein, with no fat
  • Often included in kidney-friendly diets because it’s lighter than many other protein sources

Suggested portion: 2–3 egg whites

High creatinine? 3 proteins you should eat and 3 you should never consume
  • In more advanced stages of kidney disease, it’s often recommended to avoid the yolk

3) Skinless Chicken Breast

  • Generally lighter than red meat
  • Easy to digest when grilled, baked, or boiled
  • May have a smaller impact on creatinine if you don’t overdo the portion size

Suggested portion: 80–100 g, cooked or baked


3 Proteins You Should Avoid (If You Want to Protect Kidney Function)

These foods can overload the kidneys and may contribute to higher creatinine.

1) Red Meat (Beef, Pork)

  • Can increase creatinine production
  • Often higher in pro-inflammatory fats, depending on the cut and preparation

2) Processed Meats (Sausages, Ham, Bacon)

  • Usually extremely high in sodium
  • Often contain hidden phosphorus additives, which can be especially harmful for kidney health

3) Aged Cheeses and High-Protein Dairy

  • Commonly high in phosphorus
  • Can make kidney-related mineral control more difficult

Key Guidelines to Remember

  • Don’t overdo protein: more protein can mean more creatinine and added kidney workload
  • Avoid protein powders and creatine supplements unless your clinician specifically approves them
  • Pair protein with low-potassium vegetables for a more kidney-supportive plate
  • Daily protein targets often fall around 0.6–0.8 g per kg of body weight, but the ideal amount depends on your condition and lab results

Conclusion

If your creatinine is high:

  • Quality matters more than quantity
  • Choose clean, simple proteins in small portions
  • Avoid red meat and processed foods to reduce kidney strain
