Brussels sprouts, boiled in unsalted water

Brussels sprouts are a vegetable, described here with the base trimmed and outer leaves removed, then boiled in unsalted water. They provide carbohydrate, fibre and protein, along with vitamins and minerals. Per 100g, they contain 3.2g of fibre, 3.1g of protein, 40mg of vitamin C and 124µg of folate.

Fibre supports normal bowel function, while protein is needed for the growth and repair of body tissues. Vitamin C helps the body absorb iron from plant foods, and folate is needed for normal blood cell formation. These figures relate to sprouts cooked without added salt; adding salt, butter or sauces will change their nutritional content. Full nutrient figures are in the tables below.

About these figures

Values are per 100g of the food as described (11 samples, UK, including standard, peeled and baby. Base trimmed and outer leaves removed, boiled for 4-10 minutes). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
