Why Your Diet Matters for Kidney Health

A healthy diet supports this vital function by providing the necessary nutrients and minimizing the intake of harmful substances. Poor dietary choices can lead to kidney strain, increased risk of kidney stones, and the progression of kidney disease. By choosing the right foods, you can help your kidneys work more efficiently and maintain overall health.
