About this food

Crustaceans 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.

Crustaceans's sodium (35%) is the main risk item. Cooking plainly with less sauce can cut the per-serving sodium meaningfully.
