What Are the Best Foods for Kidney Health?

Dark leafy greens

Dark leafy greens, such as spinach, kale, and chard, are dietary staples that contain a wide variety of vitamins, fibers, and minerals. Many also contain protective compounds, such as antioxidants. However, these foods also tend to be high in potassium, so they may not be suitable for people on a restricted diet or those on dialysis.
