About this food

In a CKD diet, Meat & Protein deserve attention: Fish - 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

Phosphorus leads at 29%. In CKD, track phosphorus intake and factor in the source (Animal source (higher absorption)) to judge the true burden.
