Cockles are shellfish, and the figures here describe boiled cockles sampled from fresh and frozen products. They mainly provide protein, along with vitamins and minerals, and contain little fat. Per 100g, they provide 12g of protein, 0.6g of fat, 28mg of iron and 1.2g of salt.

Protein supports the growth and repair of body tissues. Iron is needed to make haemoglobin, the protein in red blood cells that carries oxygen around the body. The salt content is worth noting for people monitoring their salt intake, including any salt added during preparation or serving. Full nutrient figures are in the tables below.
