Healthy Foods That May Be Harming Your Kidneys

39. Herbal Supplements: The Unregulated Risk

Many supplements, including those for weight loss or detox, are unregulated and contain unknown amounts of potassium, phosphorus, or other compounds that can be harmful to the kidneys. The high concentration of these minerals in a pill form can be much more dangerous than in a tea. Always consult with a doctor or a registered dietitian before taking any herbal supplements, as they can cause significant kidney damage, a danger that is often overlooked.

40. Brewer's Yeast: The Chromium and Phosphorus Burden

Brewer's yeast is often used in baking and as a nutritional supplement due to its high content of B vitamins and minerals like chromium. However, it's also a significant source of phosphorus. While phosphorus is crucial for bone health, individuals with kidney disease cannot properly filter excess amounts, leading to dangerous accumulation in the blood. This can cause weak bones and cardiovascular issues. For those with compromised kidney function, brewer's yeast and other yeast-based nutritional supplements should be avoided, as the benefits do not outweigh the risks.
