Scientists say that teaming fresh broccoli with a spicy food that contains the enzyme myrosinase significantly enhances each food’s individual cancer-fighting power and ensures that absorption takes place in the upper part of the digestive system where you’ll get the maximum health benefit. Myrosinase is the enzyme necessary to form sulforaphane, the vegetable’s cancer-preventive component. “To get this effect, spice up your broccoli with broccoli sprouts, mustard, horseradish, or wasabi. The spicier, the better; that means it’s being effective,” said Elizabeth Jeffery, a U of I professor of nutrition. The study revealed that as little as three to five servings of broccoli a week provide a cancer-protective benefit.
