Healthy Foods That May Be Harming Your Kidneys

23. Fish: A Protein and Phosphorus Challenge

While fish is celebrated for its heart-healthy omega-3 fatty acids, it's also a significant source of protein and phosphorus, which can be challenging for individuals with kidney disease. The kidneys’ job is to filter the waste products of protein metabolism, and a high-protein diet can be a strain. Additionally, many types of fish, especially canned varieties, are high in phosphorus. For those with kidney concerns, it's important to consume fish in moderation and choose a fish that is lower in phosphorus, such as cod or sea bass, to support kidney function without causing harm.

24. Yogurt: The Phosphorus and Potassium Paradox

Yogurt is often touted as a healthy breakfast or snack, but for those with kidney disease, its high phosphorus and potassium content can be a paradox. While yogurt offers beneficial probiotics and calcium, these minerals can accumulate to dangerous levels in the blood of individuals with impaired kidney function. For a kidney-friendly alternative, choose plain, unsweetened yogurt and monitor your portion sizes. You can also explore low-phosphorus, non-dairy alternatives like oat milk-based yogurts, which allow you to enjoy a similar texture and flavor without compromising your kidney health.
