Study links high calcium, potassium diet with prevention of recurrent kidney stones

Daily intake of 1,200 milligrams of calcium may help prevent first-time and recurrent kidney stones

Kidney stones can cause not only excruciating pain but also are associated with chronic kidney disease, osteoporosis and cardiovascular disease. If you’ve experienced a kidney stone once, you have a 30% chance of having another kidney stone within five years.

Changes in diet are often prescribed to prevent recurrent symptomatic kidney stones. However, little research is available regarding dietary changes for those who have one incident of kidney stone formation versus those who have recurrent incidents.

Mayo Clinic researchers in the US have designed a prospective study to investigate the impact of dietary changes. Their findings show that enriching diets with foods high in calcium and potassium may prevent recurrent symptomatic kidney stones.

“The takeaway is that patients should add more fruits and vegetables that are high in calcium and potassium to their diets. Fruits that are high in potassium include bananas, oranges, grapefruits, cantaloupes, honeydew melons and apricots. Vegetables include potatoes, mushrooms, peas, cucumbers and zucchini”, said the researchers.
