Chronic kidney disease (CKD) affects nearly 37 million Americans, and millions more are at risk worldwide. According to the Centers for Disease Control and Prevention, CKD often develops silently, with symptoms appearing only in advanced stages.
The kidneys play a vital role by filtering waste, balancing fluids, and regulating blood pressure. However, their crucial function is often overlooked until damage has progressed.
Early detection remains challenging, making it essential to adopt preventive strategies. Incorporating antioxidant-rich foods into your diet is a promising way to support kidney health—potentially slowing damage before it starts.
