Like Shrimp and Lobster, Crab are crustaceans. There are many varieties of Crab and they can be prepared in numerous ways prior to eating. If preparing a crab, worries you, then ask your local fishmonger to assist.

Crabs provide a good source of vitamins A, B1-B3, B5, B6, B12, phosphorus, potassium, zinc, copper and selenium, as well as other vitamins and minerals. They are low in fat and also contain lots of protein, about 17g per 100g serving, but dependent on the variety.

Eat both the white and brown meat. The brown meat is a particularly good source of iron, copper and calcium. Crabs contain long chain omega-3 fatty acids and are therefore thought to help boost our immune system. Other Crab benefits are believed to include the reduced risk of heart disease, lessen any feeling of tiredness and provide good bone development.
