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

Sodium leads at 38%. Cutting sodium is not only about the salt shaker - processed foods and sauces carry a lot of it.
