Overview of Chronic Kidney Disease
Chronic kidney disease (CKD) is a progressive loss of kidney function that increasingly affects cardiovascular health. Common causes include type‑1 and type‑2 diabetes, recurrent urinary infections, kidney stones, glomerulonephritis, and long‑standing hypertension.
Regardless of the underlying condition, people with CKD benefit from a diet that limits potassium, phosphorus, and sodium. Below you’ll find practical tips for managing these minerals and a collection of kidney‑friendly recipes.
Tips to Lower Potassium Intake
- Soak vegetables for 12–24 hours, changing the water twice, then boil them twice, discarding the water each time.
- When using canned vegetables, drain thoroughly and rinse to remove excess sodium and potassium‑rich brine.
- Pair high‑potassium vegetables with low‑potassium fruits to balance the overall load.
- Cook meats and fish for at least 30 minutes; this can cut potassium and phosphorus by up to half. Limit portions to about 100 g per day.
- Choose low‑potassium fruits such as apples, berries, and grapes.
- Low‑potassium vegetables include lettuce, arugula, kale, napa cabbage, leeks, onions, eggplant, peeled cucumber, spinach, and cauliflower.
- Avoid legumes, salty snacks, and animal fats.
- Include two glasses of fresh milk daily, along with fresh yogurts, white bread, white rice, and plain cereals.
- Flavor dishes with olive oil, garlic, and herbs rather than salt.
