How the numbers are sourced

  1. One database

    USDA FoodData Central, Foundation Foods 2026-04-30 and SR Legacy 2018-04. Public domain (CC0).

  2. One formula

    USDA publishes nutrients per 100 g. A serving is the nutrient per 100 g times the serving's grams divided by 100. Rounding happens only for display.

  3. One id per row

    Each food shows its USDA FDC id with a link to the USDA record.

  4. Named guidelines only

    The only thresholds shown are published ones, labeled with who published them. Where a source gives no number, we say so. See sources.

More ways to browse

What this website does not do

It does not diagnose, treat or tell you what to eat. Individual limits depend on your kidney function, labs and treatment, and are set by your care team. The pages here are reference tables, not a diet plan.

Track your own numbers against your own limits

Renal Diet adds up potassium, phosphorus, sodium, protein and fluid from an offline USDA food database, with the source on every value. No account, no scanner. You enter the limits your care team gave you, and "Can I eat this?" shows a traffic light against what is left today. A PDF report is there for your dietitian. Free to start; some features may need an optional premium subscription.

Values are USDA reference values for a standard serving. Your limits are set by your nephrologist or dietitian. Processed foods and phosphorus additives may differ. This is not medical advice.
