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

Phosphorus leads at 28%. In CKD, track phosphorus intake and factor in the source (Animal source (higher absorption)) to judge the true burden.
