Broccoli extract could be better protection against skin cancer than sunscreen, scientists claimed yesterday.
They said that tests on volunteers showed that redness caused by ultraviolet rays was markedly reduced in skin treated with the extract.
The finding was backed by parallel evidence from research on mice, said the team at Johns Hopkins University in Maryland, U.S.
Lead researcher Dr Paul Talalay said the vegetable did not act as a sunscreen which absorbs UV light, stopping it getting into the skin. Instead, it works inside the body by boosting protective enzymes which defend cells against sun damage. The extract has to be applied at least 24 hours in advance to give it time to work.
But the protection lasts for several days, even after the broccoli is no longer present in the skin, said a report in Proceedings of the National Academy of Sciences.
