This led to some health agencies recommending very high amounts of vitamin D as supplements. As time passed, more recent prospective studies and intervention trials have not supported the importance of very high vitamin D intakes; only women with very low vitamin D in the blood appear to be at greater risk for breast cancer. Which of the following statements accurately describes the research and the evidence? A. Evidence from the large population studies is highly valuable because the huge sample sizes allow scientists to draw conclusions about cause and effect. B. Prospective studies are more reliable than population studies, because the data on vitamin D intake (and sunlight exposure) are collected before breast cancer is diagnosed. C.
