Potatoes, old, mashed with butter

These are mature potatoes that have been boiled and mashed with butter and milk. They mainly provide carbohydrate, with some fat, protein and fibre. Per 100g, this preparation contains 16g of carbohydrate, 3.9g of fat, including 2.4g of saturated fat, and 337mg of potassium. The figures describe the prepared mash rather than plain boiled potatoes.

Carbohydrate provides energy for the body, while potassium supports normal nerve and muscle function. Butter contributes to the saturated fat content, which is worth noting for people monitoring their saturated fat intake. The amounts of butter, milk and any added salt can change the nutritional content of homemade mash. Full nutritional figures are shown in the tables below.
