Broccoli Compound Protects Arteries

British researchers are unlocking the secrets of broccoli. Scientists have been singing the praises of this crucifer for years because it appears to be good for the heart as well as the digestive tract. The active ingredient, sulforaphane, helps activate a protein that protects the lining of the arteries from plaque formation in mice. The protein is called Nrf2, hardly a household name. But sulforaphane seems to boost its activity in vulnerable arteries. Next, the scientists will study the effectiveness of broccoli smoothies, to see whether that works as well as pure sulforaphane. Even if it takes several more years to find out if broccoli is as effective in men as in mice, this vegetable provides essential nutrients and fiber.
