An extract made from broccoli sprouts boosts the body's natural ability to defend against the ultraviolet solar rays that cause skin cancer, reveals a study conducted by researchers at the Johns Hopkins School of Medicine and published in the Proceedings of the National Academy of Sciences. If a product could be developed from the extract, it could even provide key advantages over typical sunscreens lotions, which contain numerous carcinogenic (cancer-causing) chemicals.
"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," said study co-leader Paul Talalay. "We believe, to the best of our knowledge, that this is the first demonstration of protection against a known human carcinogen in humans."
