Cancer-promoting effects of ultraviolet (UV) radiation is counteracted by ingestion of broccoli sprout extract, in a lab animal model.
Unprotected prolonged exposure to sunlight raises the risk of ultraviolet (UV) radiation to cause or accelerate skin aging as well as skin cancer. Albena T. Dinkova-Kostova, from Johns Hopkins University (Maryland, USA), and colleagues fed broccoli sprout extracts, high in glucoraphanin, a precursor to compounds in broccoli that have been identified as potent anti-carcinogens, to laboratory mice previously exposed to UV radiation. The researchers found that a daily dose of 10 moles of glucoraphanin inhibited the subsequent development of skin tumors, with skin tumor incidence reduced by 25% and tumor volume by 70%.
