Your kidneys play a crucial role in filtering toxins, balancing fluids, and maintaining overall health. But when kidney function starts to decline, proper nutrition can make a world of difference. So, what foods help repair kidneys? Let’s explore science-backed foods that support kidney detox and overall kidney health.
Why Kidney Health Matters
Kidneys are responsible for:
-
Filtering waste and excess fluids from the blood
-
Regulating blood pressure
-
Balancing electrolytes
-
Producing essential hormones
Poor kidney function can lead to serious health issues like chronic kidney disease (CKD), kidney stones, and even kidney failure. The good news? A kidney-friendly diet can help slow down damage and, in some cases, promote healing.
