Oysters are shellfish, and the figures here describe them raw. They provide protein alongside vitamins and minerals, including zinc, vitamin B12, iron and iodine. Per 100g, raw oysters contain 11g of protein, 59mg of zinc, 17µg of vitamin B12 and 1.3g of salt.
Protein supports the maintenance and repair of body tissues, while zinc contributes to normal immune function and wound healing. Vitamin B12 is needed for normal nerve function and red blood cell formation. The salt content is worth noting for people monitoring their salt intake. Raw oysters can carry bacteria and viruses that cause food poisoning, particularly in people with weakened immune systems. Full nutritional figures are in the tables below.

About these figures
Values are per 100g of the food as described (Analytical and literature sources). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
