What's good for your diet may also guard against skin cancer

THURSDAY, Oct. 25 (HealthDay News) -- What's good for your diet may also guard against skin cancer. Scientists have discovered that an extract of broccoli sprouts protects the skin against the sun's harmful ultraviolet rays.
"We looked in vegetables, and it turned out they had a rather large quantities of a compound that induced this system, particularly in cruciferous vegetables such as broccoli, cabbage, Brussels sprouts, et cetera," Talalay said.
The compound, called sulforaphane, is found in broccoli sprout extracts and was first identified by Talalay and his colleagues more than 15 years ago. Sulforaphane has been shown to inhibit tumor development in animals.
"If you apply an extract of broccoli sprouts that contains high levels of sulforaphane to regions of human skin, you can protect them very substantially," Talalay said. "We believe, to the best of our knowledge, that this is the first demonstration of protection against a known human carcinogen in humans."
