A nursing student asks a nurse about the recommendations for vitamin supplements to prevent cancer. Which statement by the student indicates a need for further teaching?
a. "Foods rich in antioxidant vitamins may confer protection by other means."
b. "Observational studies provide clear proof that some antioxidants reduce the risk of cancer."
c. "Randomized controlled studies have not demonstrated cancer prevention benefits."
d. "Some vitamins have an increased cancer risk associated with too low and too high amounts."
B
No clear evidence indicates that antioxidant vitamins lead to a reduced risk of cancer. Some ob-servational studies show a link between the consumption of foods high in antioxidants and lower cancer rates, but this link may be related to other components of these diets, such as the high fi-ber also found in such foods. Some vitamins are linked to higher cancer rates when consumed in both too-low and too-high amounts.
