Asparagus, roasted in rapeseed oil

Asparagus is a vegetable eaten for its young stems and tips. This entry describes asparagus roasted in rapeseed oil, with the tough bases of the stems removed. It provides protein, fibre and folate, with some fat from the added oil. Per 100g, it contains 3.5g of protein, 1.6g of fibre, 123µg of folate and 1.5g of fat.

Folate supports normal cell division and the formation of red blood cells, while fibre helps maintain normal bowel function. Rapeseed oil provides mainly unsaturated fat. The amount of oil used affects the fat and energy content, and added salt can change the salt content of the prepared dish. Full nutritional figures are in the tables below.
