The kidneys play a vital role in maintaining overall health by filtering waste from the blood, regulating electrolyte and acid-base balance, and helping control blood pressure.
However, certain dietary minerals can accumulate in the urine and form crystals, disrupting normal kidney function. These crystal formations are known as kidney stones or renal calculi, and their chemical composition may vary from person to person.
Kidney stones typically form when substances like calcium and oxalate crystallize in the urine. Normally, the body’s natural urine chemistry helps prevent this. But when this balance is disturbed, stones may form, leading to pain and other complications.
A balanced diet is essential not only for preventing kidney stones but also for supporting kidney health during treatment. In this article, we highlight some of the best foods to include in your diet if you’re prone to or currently dealing with kidney stones.
