How the humble cabbage can stop cancers
Scientists say they have discovered why some vegetables - including cabbage, broccoli and kale - can reduce the risk of bowel cancers.That cruciferous veg is good for the gut has never been in doubt but a detailed explanation has been elusive.The team at the Francis Crick Institute found anti-cancer chemicals were produced as the vegetables were digested.
