Winkles, boiled, weighed with shells

Winkles are small edible sea snails. These figures describe boiled winkles weighed with their shells, rather than the edible flesh alone. Per 100g weighed with shells, they provide 2.9g of protein, 0.2g of fat, 0.35g of salt and 7µg of vitamin B12. Protein is the main macronutrient provided, with only trace amounts of carbohydrate.

Protein supports the growth and repair of body tissues. Vitamin B12 is needed for normal nerve function and the formation of red blood cells. The salt content is relevant for people monitoring their salt intake. Including shells in the measured weight affects comparisons with shellfish figures given for edible flesh only. Full nutrient figures are in the tables below.

About these figures

Values are per 100g of the food as described (Calculated from boiled 16-270). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
