Whelks are edible marine snails, classed as shellfish. The figures here describe whelks boiled in salted water. They mainly provide protein, with 20g per 100g, alongside 1.2g of fat. They also provide vitamin B12, at 21µg per 100g, and minerals including zinc, copper and iron. Their salt content is 0.7g per 100g.
Protein supports the growth and repair of body tissues. Vitamin B12 helps maintain normal nerve function and is needed for red blood cell formation. The salt content is worth noting for people monitoring their salt intake, particularly as these whelks were cooked in salted water. Full nutrient figures are given in the tables below.

About these figures
Values are per 100g of the food as described (10 samples from assorted outlets, boiled in salted water). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
