How this compares with published guidance

Under 200 mg At 4 mg potassium per serving, this is under the 200 mg line that the National Kidney Foundation (Potassium in Your CKD Diet, updated May 5, 2023) uses for its comparison "low" column.

The 200 mg line applies to a serving, and the serving here is the USDA household portion listed above, which may not match the serving size used on other lists. NKF gives no daily potassium target. Your own limit comes from your care team.

Phosphorus. NKF (Phosphorus and Your CKD Diet) gives no per-serving cutoff, so no label is applied to 8 mg. See where it sits on the phosphorus ranking.

Processed or packaged item. Products of this kind can differ from this USDA reference value, and phosphorus additives may add phosphorus that a generic value does not show. NKF says additive phosphorus is completely absorbed and advises checking ingredient lists for additives with "phos" in the name. Check the label of the product you buy.

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.
