Diet for Calcium Stones
A diet for Calcium Stones should limit substances that increase blood and urine levels of calcium, such as caffeine and sodium. It is better to avoid foods and beverages such as coffee, chocolate, and fast foods.
You may also increase the amount of foods that reduce excretion of calcium into the urine, such as cranberries.
Mineral supplements that are reported to reduce urinary calcium are magnesium and potassium.
Vitamin B6 is also reported to reduce urinary calcium.
Diet for Calcium Oxalate Stones
A diet for Calcium Oxalate Stones should limit substances that increase levels of both calcium and oxalate in the blood and urine. Substances that increase levels of oxalates are oxalate-rich foods and Vitamin C. Vitamin C converts to oxalate in the urine.
Oxalate-rich foods include spinach, rhubarb, colocasia, beets, nuts, chocolate, and black tea.
You may also add substances that reduce the levels of oxalate in the urine, such as Vitamin B 6 and magnesium.
Diet for Calcium Phosphate Stones
If you suffer from Calcium Phosphate Stones your diet should be compatible with treatments for the underlying metabolic conditions that caused the stone. Your first step should be to consult your doctor about this.
High urine pH (low acidity of the urine) is also correlated with phosphate stone formation. With your doctor’s approval, you may increase the amount of urine acidifiers in your diet. Such foods include animal proteins and citrus fruits.
