Leeks, boiled in unsalted water

Leeks are vegetables in the onion family. The figures here are for leeks that have been trimmed, sliced and boiled in unsalted water. They provide small amounts of carbohydrate and protein, along with fibre and folate. Per 100g, they contain 2.5g of carbohydrate, 1.9g of fibre and 44µg of folate, with an energy content of 68 kJ.

Fibre supports normal bowel function, while folate contributes to normal blood cell formation. Leeks prepared this way contain little fat or saturated fat. Boiling without added salt also keeps their salt content low; adding salt, butter or sauces will change the nutritional content of the finished dish. Full nutrient figures are provided in the tables below.

About these figures

Values are per 100g of the food as described (11 samples, UK, trimmed and damaged outer leaves removed. Sliced and boiled for 5-8 minutes). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
