Yes Broccoli contains carotene, vitamin A, phosphorus, calcium, vitamin C, folic acid, potassium, protein and other nutrients. If boiled in water for a long time, vitamin C in it will indeed lose a lot after encountering high temperature, but most of the nutrients such as carotene, protein and calcium are resistant to high temperature. Therefore, broccoli cooked for a long time is not without any nutrition except yellowing.
