How this compares with published guidance
Under 200 mg At 102 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 14 mg. See where it sits on the phosphorus ranking.
Phosphorus additives matter for processed versions: NKF says phosphorus from additives is completely absorbed. A prepared or packaged version of this food may differ from the USDA value above.
