How does sodium affect kidney stones?

High sodium intake increases calcium in urine (hypercalciuria), which raises the risk of calcium-based kidney stones. The general recommendation is under 2,300 mg/day — lower if you're actively preventing stones.

What's a safe daily sodium target?

Aim for under 2,000-2,300 mg per day. Check labels on packaged foods — sodium adds up quickly. Cooking at home with fresh ingredients gives you the most control over sodium intake.

How do I reduce sodium when eating out?

Ask for sauces and dressings on the side. Choose grilled/steamed over fried. Skip the soup (often very high sodium). Request no added salt. These small changes make a measurable difference.
