Broccoli, green, steamed

Green broccoli is a vegetable; the figures here describe Calabrese broccoli cooked by steaming. It provides fibre, protein and a range of vitamins and minerals, including vitamin C and folate. Per 100g, steamed broccoli contains 3.8g of fibre, 4.1g of protein, 60mg of vitamin C and 72µg of folate.

Fibre supports normal bowel function, while vitamin C helps the body absorb iron from plant foods and supports normal immune function. Folate is needed for normal cell division and the formation of blood cells. Steamed broccoli is low in salt and saturated fat, although adding salt, butter or sauces changes its nutritional content.
