Prawns, standard, dried

Prawns are shellfish, and the figures here describe them in dried form. Dried prawns mainly provide protein, with 83g per 100g. They also contain 4.9g of fat, 7.9g of salt and 13µg of vitamin B12 per 100g. Drying removes much of the water, concentrating the nutrients compared with prawns that have not been dried.

Protein is needed for the growth and repair of body tissues, while vitamin B12 supports normal nerve function and the formation of red blood cells. The high salt content is worth noting for people monitoring their salt intake. Prawns are also a crustacean allergen. Full nutrient figures are provided in the tables below.
