About this food
Fish is a common member of 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 helps when choosing similar foods.
Nutrient insight
Phosphorus leads at 11%. In CKD, track phosphorus intake and factor in the source (Animal source (higher absorption)) to judge the true burden.
