In The News, Fall 2022: Calcium and Potassium Protective Against Kidney Stones
Mayo Clinic researchers found that lower dietary intakes of calcium and potassium are important risk factors for both incident (first-time) kidney stone formation and recurrence, while lower caffeine, phytate, and fluid intakes are predictors of recurrence only.
Dietary factors were assessed based on a food frequency questionnaire administered to 411 people with symptomatic incident kidney stones and 384 controls, all of whom were patients at Mayo Clinic in Rochester (Minnesota) or Mayo Clinic in Florida between 2009 and 2018.
Kidney stones are not only painful but are also associated with chronic kidney disease, osteoporosis, and cardiovascular disease. People who have experienced an incident kidney stone face a 30% likelihood of recurrence over the next five years.
The researchers stated that fluid intake of less than 3,400 ml per day (about 115 ounces) – including fluid from foods such as fruits and vegetables – is associated with first-time stone formation. They also concluded that daily intake of 1,200 mg of calcium may help prevent both incident and recurrent stones. No specific potassium dosage was recommended.
