Shellfish and seafood: calories, protein and salt

Every shellfish and seafood product broken down by portion, with fresh, cooked and coated products compared.

Shellfish is high in protein and very low in fat, which makes it one of the leanest options available. Salt is the figure that varies most, since some varieties carry it naturally and others gain it in processing.

Naturally occurring salt

Prawns, mussels and other seafood carry sodium from their environment, so even plain products are not salt-free.

Brined and pre-cooked products add more. Fresh and frozen raw shellfish sit lowest.

Coating and preparation

Breaded scampi and battered calamari follow the same pattern as coated fish, with the coating contributing most of the added calories.

Shellfish is a common allergen, and cross-contamination in prepared products is worth checking on the allergen line rather than the nutrition panel.
