About this food

Crustaceans sits in the Meat & Protein group. 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

Crustaceans's phosphorus (26%) is worth noting - especially with Animal source (higher absorption) as the source, since absorption differs a lot.
