Your kidneys filter around 180 liters of blood every day. With the right nutrition and hydration you take a lot of work off them and prevent stones and loss of function.
Hydration: the most important rule
Water is the number-one remedy. Aim for 2.5–3 liters daily, so urine stays pale yellow. Enough fluid dilutes stone-forming substances and keeps filtration running.
Eating kidney-friendly
- Cut salt – eases blood pressure and the kidneys
- Plant-forward eating, animal protein in moderation
- Citrate-rich fruits like lemon
- Oxalate-rich foods (spinach, rhubarb) in moderation
- Potassium & magnesium from vegetables for stone prevention
Important special case: existing kidney disease
With chronic kidney disease (CKD), partly opposite rules apply – protein, potassium, phosphate and sometimes fluid intake must be limited. These recommendations are for healthy kidneys as prevention; with known kidney disease, always follow your medical/dietary guidance.
Useful supplements
If you don't get enough citrate, magnesium or cranberry protection from food, targeted supplements can help. The basics always remain: drink enough and eat little salt.
FAQ
