CKD 膳食 计算器

A CKD (chronic kidney disease) meal calculator is a tool that helps kidney patients track the phosphorus, sodium, potassium, calories, and protein in the foods they eat. It compares your meal against the recommended daily limits for your CKD stage (Stage 3, 4, 5, or dialysis), so you can build kidney-safe meals with confidence.

All nutrient values come from the USDA FoodData Central database (Foundation Foods, FNDDS Survey, and Branded datasets) — the same data used by registered dietitians. Daily CKD limits follow KDOQI clinical practice guidelines and are stage-adjusted. Always confirm your personal targets with your renal dietitian, as individual needs vary.

No — you can use the calculator and search 13,000+ foods completely free without signing up. An account is only needed if you want to save meals to come back to later. Free accounts get 3 saved meals; supporters get unlimited saves.

Typical daily limits for CKD Stage 3-4 are: phosphorus ≤ 1,000 mg, sodium ≤ 2,300 mg, potassium ≤ 2,000 mg. Stage 4 and dialysis patients usually have stricter targets. The calculator automatically adjusts when you select your stage. Your nephrologist may set personalised limits based on your lab results.

Yes. Use the "Print PDF" button to print your meal or save it as a PDF (use "Save as PDF" in the print dialog). This is useful for bringing your meal plans to dietitian appointments. Logged-in users can also save meals to their account for quick access later.

Yes. Select "Dialysis" from the stage selector and the calculator will adjust limits accordingly (phosphorus ≤ 800 mg, sodium ≤ 2,000 mg, with adjusted potassium and calorie targets). Dialysis patients typically need more calories and protein than pre-dialysis CKD patients — always consult your dialysis dietitian for personal targets.
