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
On the phosphorus angle (29%), Fish belongs in the watch category. Pairing it with low-phosphorus sides like white rice or egg whites balances the meal.
