Potatoes, new and salad, flesh only, raw

New and salad potatoes are starchy vegetables. These figures describe the raw flesh only, without the skin. They mainly provide carbohydrate, with small amounts of protein and fibre, as well as vitamins and minerals. Per 100g, they contain 16g of carbohydrate, 1.8g of fibre, 7mg of vitamin C and 320mg of potassium.

Carbohydrate supplies energy, while potassium supports normal nerve and muscle function. Vitamin C helps the body absorb iron from plant foods. The raw flesh contains little fat or salt, but preparation can change the nutritional content. Added oil, butter or salt can increase energy, saturated fat or salt intake. Full nutrient figures are in the tables below.
