Leeks, roasted in rapeseed oil

Leeks are vegetables in the onion family. The figures here describe trimmed leeks roasted in rapeseed oil. They provide carbohydrate and fibre, with some fat from the added oil and a small amount of protein. Per 100g, they contain 4.5g of carbohydrate, 3.1g of fibre, 1.9g of fat and 1.7g of protein.

Fibre supports normal bowel function. Rapeseed oil provides mainly unsaturated fats, and the saturated fat content of these roasted leeks is low. The supplied data show only trace amounts of salt, although adding salt during cooking would change this. The amount of oil used also affects the fat and energy content. Full nutritional figures are in the tables below.
