📖 Overview

What this chart is built on

Kidney stones are forming crystals in concentrated urine. Hydration is #1 — 3L water daily. Limit oxalates, sodium, and animal protein. The CALCULATED type matters: 80% are calcium oxalate, then uric acid, struvite, cystine. The diet differs by type.

🔬 The Science

Why this works

The evidence behind each food choice.

  1. 1Concentrated urine = stone formation. Dilute urine = stone prevention. Pee should be pale yellow.
  2. 2Calcium with meals binds oxalates in the gut and prevents absorption.
  3. 3Citrate (lemon juice) directly inhibits stone formation.
  4. 4Sodium increases calcium excretion — high salt diets cause stones.
  5. 5Animal protein in excess increases uric acid and lowers urinary citrate.
💡 Tips

Beyond the food

Habits that multiply your results.

1
Drink water until urine is pale yellow — about 3L daily
2
Squeeze lemon in water — citrate prevents stones
3
Eat calcium WITH meals containing oxalates
4
Reduce sodium below 2300mg daily
5
Identify stone type before changing diet — different types need different approaches
6
Avoid Vitamin C supplements above 500mg if stone-prone
