Potatoes, old, microwaved, flesh and skin

Old potatoes are mature potatoes, rather than new potatoes. The figures here describe potatoes microwaved with their skin on, with both flesh and skin eaten. They mainly provide carbohydrate, with 22g per 100g, alongside 2.7g of fibre, 2.6g of protein and 585mg of potassium.

Carbohydrate provides energy, while fibre supports normal bowel function. Potassium contributes to normal muscle and nerve function. These potatoes contain little fat or salt on their own. Added butter, cheese or salty toppings can increase the energy, saturated fat and salt content of the meal, which may be relevant for people monitoring these nutrients. Full nutrient figures are provided in the tables below.
