About this food
Fish belongs to the Meat & Protein category. 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 phosphorus is 23% of the limit, from Animal source (higher absorption). On a phosphorus-restricted diet, limit how often and how much you eat it.

Practical tips
A handy approach - Boiling meat first and discarding the water removes some phosphorus and potassium; prefer low-phosphorus proteins like egg whites.
