For optimal kidney health.....
Fruits and vegetables, particularly cranberries, blueberries, spinach, onions, celery and asparagus, are beneficial for kidney function. Focusing your diet on fresh, unprocessed foods is also important, and generally a heart-healthy diet is one that will be beneficial for your kidneys as well. Excess amounts of sodium, potassium, animal proteins and sugar should be avoided for kidney health.

You may also want to use caution when consuming genetically modified foods, as residues of glyphosate-based herbicides (like Roundup) widely used on GM crops and modified Bt insecticidal toxins that are produced by the GM plants themselves have been found to kill human kidney cells.
