Calcium stones - limit milk/dairy products; provide acid-ash diet to acidify urine (cranberry or prune juice, meat, eggs, poultry, fish, grapes, and whole grains)
______________________________________________________________
Oxalate stones - avoid excess intake of foods/ fluids high in oxalate (tea, chocolate, rhubarb, spinach); maintain alkaline-ash diet to alkalinize urine (milk; vegetables; fruits except prunes, cranberries, and plums)
Uric acid stones - educe foods high in purine (liver, beans, kidneys, venison, shellfish, meat soups, gravies, legumes); maintain alkaline urine 7.
