Foods To Avoid For Optimal Kidney Health
59. Protein Powders – The Fitness Pitfall

Protein powders are popular among fitness enthusiasts, but they pose risks for those with impaired kidney function. Many contain more protein per scoop than the average person needs—plus hidden phosphorus and potassium in the form of additives. Excess protein can strain the kidneys, especially in people already at risk or in early stages of chronic kidney disease.
60. Tomato-Based Pasta Sauces – A Tangy Red Flag
Jarred tomato sauces may be pantry staples, but they’re often a nightmare for kidney health. Tomatoes are naturally high in potassium, and commercial sauces pile on the sodium—sometimes over 500 mg per half-cup. Add in cheese or salted pasta water, and your kidneys are on cleanup overload. Look for low-sodium versions or make your own with roasted red peppers or olive oil, garlic, and fresh herbs.
