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 sodium (46%) is the main risk item. Cooking plainly with less sauce can cut the per-serving sodium meaningfully.
