These figures describe mature potatoes boiled in salted water, with the skin removed and only the flesh included. They mainly provide carbohydrate, with 18g per 100g, and also supply some fibre, vitamin C and potassium. Per 100g, they contain 1.6g of fibre, 9mg of vitamin C and 365mg of potassium.

Carbohydrate is a source of energy for the body, while fibre supports normal bowel function. Vitamin C helps the body absorb iron from plant foods, and potassium contributes to normal muscle and nerve function. Salt added during cooking contributes to the salt content, which is worth noting when monitoring salt intake. Full nutrient figures are provided in the tables below.

About these figures

Values are per 100g of the food as described (22 samples, autumn and winter, including white and red varieties, pre-packed and loose, based on boiled in unsalted water). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
