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 the top contributor (27% of its limit). Source matters: animal phosphorus absorbs at 60-80%, additive phosphorus near 100% - the same number can mean very different real loads.
