Foods High in Calcium Oxalate
Calcium stones are the most common renal stones comprising about 80% of the stones. There are three variations of calcium renal stones i.e (1):
- Pure calcium oxalate stone which is observed in 50 percent of cases
- Calcium phosphate kidney stone(5 percent cases)
- A mixture of both(found in 45 percent of calcium kidney stone cases)
Studies have shown that hypercalcemia causes kidney stones (2). Hypercalcemia-a condition in which the calcium level in your blood is above normal.
That’s why both foods that are high in calcium or oxalate can cause kidney stones. So what foods should be avoided to reduce the risk of calcium renal stones?
The following foods consumption to be restricted to get rid of calcium kidney stones:
