Kidney diet

5 diet traps in chronic kidney disease

Some "healthy" foods are traps for kidney patients — the first one is in many kitchens every day.

  1. 1Salt substitutes and "low-sodium" soy sauce: sodium is often replaced with potassium chloride, which can raise blood potassium when kidneys are weak.
  2. 2Phosphate additives in processed food: watch for "phosphate" or "phosphoric acid" on the label — absorption is close to 100%, far higher than natural foods.
  3. 3Star fruit: contains a neurotoxin; people with reduced kidney function may get intractable hiccups, confusion or seizures, which can be fatal.
  4. 4High-sodium takeaway and pickled food: guidelines advise less than 2.3 g sodium a day (about 6 g salt).
  5. 5Protein powder on your own: non-dialysis CKD stages 3–5 are advised 0.55–0.6 g/kg/day; dialysis patients actually need more — ask a dietitian first.

Limits differ from person to person — follow the targets set by your doctor and renal dietitian. Try the free diet calculator on this site.

0–5Hand holding salt substitute, big text "TRAP?"Some foods that look healthy are actually traps for people with kidney disease.
5–16Zoom on label: "potassium chloride"One: salt substitutes and low-sodium soy sauce. They often swap sodium for potassium chloride. When kidneys are weak, potassium builds up.
16–27Snack / ham label with "phosphate" circledTwo: phosphate additives in processed food. If you see "phosphate" on the label, be careful — nearly all of it is absorbed.
27–36Star fruit photo + warning signThree: star fruit. It contains a neurotoxin. With reduced kidney function it can cause endless hiccups, confusion, even death.
36–46Noodle soup, pickles, "<2.3 g sodium/day"Four: high-sodium takeaway and pickles. Guidelines say less than 2.3 grams of sodium a day — about six grams of salt.
46–55Protein powder tub + "ask a dietitian"Five: buying protein powder on your own. Before dialysis protein should be lower; on dialysis it should be higher. Big difference — ask a dietitian.
