Research has shown repeatedly that cruciferous vegetables fight cancer.
According to Elizabeth Jeffery, a professor of nutrition at the university, it takes only 3 to 5 servings of broccoli per week to obtain cancer prevention benefits.
But it’s important that the broccoli you eat still has a live enzyme called myrosinase. This enzyme is needed to form the sulforaphane, its active cancer-fighting substance.
Jeffery recommends steaming broccoli for only two to four minutes to protect both the enzyme and the vegetable’s other nutrients.
Another way to make sure you’re getting myrosinase is to eat raw broccoli sprouts. They have an abundant supply.
The researchers noted that some health-conscious consumers use broccoli powder supplements especially if they don’t like broccoli. But taking supplements doesn’t always work if the supplements don’t contain the enzyme. The researchers hypothesized that myrosinase combined with broccoli powder would increase the sulforaphane content.
The study was small. Four healthy men ate broccoli sprouts alone, broccoli powder alone, or a combination of the two. Tests performed three hours after the meals showed an almost twofold increase in sulforaphane absorption when sprouts and powder were eaten together.
According to the researchers, this indicated that myrosinase from the broccoli sprouts produced sulforaphane not only from the sprouts but also from the broccoli powder.
Broccoli sprouts are becoming very popular. Researchers at Johns Hopkins University have developed a line of broccoli sprouts and sprout blends under the brand name BroccoSprouts. You can find them at health foods stores, Whole Foods Markets, and many supermarkets.
Broccoli sprouts should be eaten raw. They are great on sandwiches, in wraps, or as a salad topping.
