Potatoes, old, boiled in unsalted water, flesh only

Dernière mise à jour 4 Nov 2026

Respecte les directives éditoriales

Old potatoes are mature potatoes rather than new potatoes. The figures here describe potato flesh only, without the skin, boiled in unsalted water. They mainly provide carbohydrate, with some fibre, vitamins and minerals. Per 100g, they contain 18g of carbohydrate, 1.6g of fibre, 365mg of potassium and 9mg of vitamin C.

Carbohydrate provides energy, while fibre supports normal bowel function. Potassium contributes to normal nerve and muscle function, and vitamin C helps the body absorb iron from plant foods. Potatoes prepared this way are low in fat and contain no added salt. Adding butter or salt changes their nutritional content. Full nutrient figures are in the tables below.
