10 Foods That Cause Kidney Stones
Kidney Stones Causing Food #7: Rhubarb
Rhubarb is an herbaceous perennial that is edible. Although it is a vegetable, it is often used like a fruit. Rhubarb is often used in desserts such as pies. The plant contains high levels of oxalic acid. Individuals at risk of kidney stones should avoid eating rhubarb as it can cause kidney stones.
Oxalic acid is a colorless crystal that can be found in various plants. While there are many good foods that contain oxalic acid, the crystal can bind with other minerals such as calcium in the intestines to form kidney stones. The leaves and raw roots should be avoided at all costs as the concentration of oxalic acid is highest in these parts of the plant.
