About this food

Fish (Meat & Protein). 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. This is the same lens used for similar items.

Nutrient insight

Fish's sodium (20%) is the main risk item. Cooking plainly with less sauce can cut the per-serving sodium meaningfully.

Practical tips

Worth remembering: Boiling meat first and discarding the water removes some phosphorus and potassium; prefer low-phosphorus proteins like egg whites.
