Potatoes, new and salad, boiled in unsalted water, flesh and skin

New and salad potatoes are starchy vegetables. The figures here describe potatoes boiled in unsalted water, with both flesh and skin included. They mainly provide carbohydrate, with some fibre and small amounts of protein. Per 100g, they contain 15g of carbohydrate, 1.8g of fibre, 377mg of potassium and 0.01g of salt.

Carbohydrate provides energy for the body, while fibre supports normal bowel function. Potassium helps nerves and muscles work normally. These potatoes contain little salt when boiled without added salt, which is relevant for people monitoring their salt intake. Adding salt, butter or sauces changes the nutritional content of the dish. Full nutrient figures are given in the tables below.
