Potatoes, old, roasted in lard

These figures describe mature potatoes that have been parboiled and then roasted in lard. They mainly provide carbohydrate, with fat from the lard, as well as some fibre and protein. Per 100g, they contain 26g of carbohydrate, 5.7g of fat, including 2.3g of saturated fat, and 2.7g of fibre.

Carbohydrate provides energy, while fibre supports normal bowel function. These potatoes also provide potassium, which helps nerves and muscles work normally. The lard contributes saturated fat, which is worth noting for people monitoring their saturated fat intake. Added salt or salty accompaniments will increase the salt content of the meal. Full nutrient figures are in the tables below.
