Broccoli contains significant levels of sulforaphane, a substance that helps detoxify carcinogens from the body, may limit the damage of serious lung disease caused by smoking and protect against damage to blood vessels caused by diabetes. Research at the University of Illinois indicates that teaming fresh broccoli with a spicy food that contains the enzyme myrosinase enhances broccoli’s anti-carcinogenic effects. Suggested teammates include radishes, cabbage, arugula, brussels sprouts, mustard and horseradish or wasabi.
