Broccoli is extremely rich in iron, calcium (138mg / 100g) and vitamin C (116mg / 100g). As a comparison we have the orange with about 50mg / 100g of vitamin C and the cow's milk with about 120mg / 100g of. If we add to this its low calorie content (29kcal / 100g), we conclude that broccoli is a hugely interesting food from a nutritional point of view.
