Crayfish are freshwater shellfish, and the figures here describe them raw. They mainly provide protein, with little fat, alongside minerals including selenium and iodine. Per 100g, raw crayfish contain 15g of protein, 0.8g of fat, 70µg of selenium and 100µg of iodine.
Protein supports the growth and repair of body tissues. Selenium contributes to normal immune function, while iodine is needed to make thyroid hormones, which help regulate metabolism. Crayfish are crustaceans and can cause reactions in people with a crustacean allergy. Cooking methods and added ingredients can change the fat and salt content of the finished dish. Full nutritional figures are provided in the tables below.
