Broccoli is high in phytochemicals, including sulforaphane and indole-3-carbinol, which may detoxify cancer-causing substances before they act.
In women, indole-3-carbinol may turn the estrogen associated with breast cancer into a more benign form. Studies link regular consumption of cruciferous vegetables like broccoli to a reduced risk of breast, colon and stomach cancers.
Broccoli is a excellent source of beta-carotene, fiber and vitamin C (1 cup contains more C than an orange).
Nutrients of cruciferous are best obtained by cooking light and chewing well.
Options instead of broccoli are brussels sprouts, cabbage and bok choy.
