A Carrot a Day Keeps Cancer Away

Among all the malignancies, lung cancer is the biggest killer: more than 100,000 Americans a year die of the disease. Giving up smoking is one of obvious way to reduce the risk, but another answer may lie in the kitchen. According to a new report, even heavy smokers may be protected from developing lung cancer by a simple dietary measure: a daily portion of carrots, spinach or any other vegetable or fruit containing a form of vitamin A called carotene.
The finding, published in the British medical journal The Lancet, is part of a long-range investigation of diet and disease. Since 1957 a team of American researchers has monitored the dietary habits and medical histories of 2,000 middle-aged men employed by the Western Electric Co. in Chicago. Led by Dr. Richard Shelelle of Chicago’s Rush-Presbyterian, St. Luke’s Medical Center, the researchers recently began to sort out the links between the subjects’
A. Those with the lowest level of carotene intake.
B. Those with the highest level o carotene intake.
C. Those who ate only foods containing carotene.
D. Those with the lowest intake of carrots.
