King prawns are shellfish, and these figures describe warm-water king prawns purchased cooked, either frozen or chilled. They mainly provide protein, with little fat, and also supply vitamins and minerals. Per 100g, they contain 16g of protein, 0.4g of fat, 1.6g of salt and 1.4µg of vitamin B12.
Protein is needed to build and maintain body tissues. Vitamin B12 supports normal nerve function and the formation of red blood cells. The salt content is worth noting for people watching their salt intake, even though prawns contain little fat. Salt levels may vary between products. Full nutrient figures are provided in the tables below.

About these figures
Values are per 100g of the food as described (11 samples, 11 products, warm-water prawns (Penaeus vannamei), frozen and chilled). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
