  schema:description "Beta-carotene, the orange pigment in carrots, was tested in large trials as a way to prevent cancer. In men who smoked it increased lung cancer rather than preventing it, and the United States Preventive Services Task Force recommends against taking it to prevent cancer. Eating the vegetables that contain it is a different thing and is good for you."@en ;
