How to prevent kidney stones?

To prevent kidney stones, Dr. Rena Malik and Andrew Huberman recommend several dietary and lifestyle adjustments:

1. Increase Fluid Intake: Aim for 2-3 liters of fluid daily to dilute the substances in urine that lead to stone formation.

2. Reduce Oxalate Intake: Foods high in oxalate, such as spinach and rhubarb, should be consumed less frequently. Switching to a different green can be beneficial if you consume spinach regularly.

3. Increase Citrate Intake: Citrate helps prevent stone formation. Increasing intake of fruits and, interestingly, Crystal Light, which has a high citrate content, can be beneficial.

4. Decrease Protein Intake: Particularly from sources rich in purines like red meat, as these can increase the risk of stone formation.

These suggestions aim to address common triggers of kidney stones, such as dehydration and dietary factors like high oxalate and protein intake. It's always good to consult with a healthcare provider for tailored advice, especially after a stone event, as metabolic abnormalities can vary per individual1.
