About this food

Fish sits in the Meat & Protein group. Animal proteins tend to be higher in phosphorus, and animal phosphorus absorbs at 60-80% versus 30-50% for plants. Choosing low-phosphorus proteins such as egg whites or tofu, or controlling portions of red meat, is a common CKD approach.

Nutrient insight

Fish's potassium reaches 20% of the limit - the leading item. Patients with normal blood potassium can eat moderate amounts; those with hyperkalemia should be more careful.
