Healthy Foods That May Be Harming Your Kidneys

33. Kombucha and Other Fermented Drinks: The Potassium and Phosphorus Trap

Kombucha is a trendy fermented drink known for its probiotic benefits, but for individuals with kidney disease, it can be a hidden trap. The fermentation process can concentrate minerals, particularly potassium and phosphorus, which are often found in the teas and fruits used to flavor it. While these minerals are beneficial for healthy individuals, an excess can be dangerous for those with impaired kidney function. It's a prime example of a “healthy” food that should be approached with caution.

34. Beets and Beetroot Juice: Oxalate Powerhouses

Beets and beetroot juice are often promoted for their ability to lower blood pressure due to their high nitrate content, which converts to nitric oxide. However, like spinach, they are also very high in oxalates. For people with a history of calcium oxalate kidney stones, a high intake of beets can significantly increase their risk of stone formation. If you are looking to lower your blood pressure, consider other foods and drinks that do not contain oxalates, such as fruits and vegetables, and consult a healthcare professional.
