One significant recommendation is to decrease the intake of high-oxalate foods. Oxalate is a compound that can bind with calcium in the kidneys, potentially leading to the formation of calcium oxalate stones, which are the most common type of kidney stones. By reducing high-oxalate foods, which include spinach, rhubarb, beets, nuts, and chocolate, individuals can help minimize the risk of developing more stones in the future.
