The news about vitamins keeps getting worse. Many studies published in the last few years shows that a variety of popular supplements don’t do anything to reduce the risk of developing heart disease, stroke or a variety of cancers.
But what about multivitamins? These combination pills, which【C1】______10 to 30 vitamins and【C2】______, are the most popular supplements sold in America. A report published recently suggests they shouldn’t be.
The study【C3】______161,808 participants in the Women’s Health Initiative, a long-term effort to【C4】______risk factors for cancer, heart disease and bone health in elderly women.【C5】______in the nationwide study included white, black, Asian and Native American women. They were followed for an average of nearly eight years.【C6】______, 41.5% of study participants took some version of a multivitamin. Those women were more likely to be white and college-educated, live in the West, exercise and have a lower body mass index.
However, women who took multivitamins weren’t any more likely to【C7】______a diagnosis of breast, lung, stomach, and other cancers than were women who didn’t take multivitamins. Nor were multivitamins in general helpful in【C8】______heart attacks, strokes or reducing the risk of death from any【C9】______during the study period. The research team did find one【C10】______benefit: The 3,741 women who took stress multivitamins—formulations【C11】______higher doses of several B vitamins along with an extra amount of vitamin C—were 25% less likely to have a heart attack. No other correlations between vitamins and health outcomes were statistically【C12】______.
The study provides【C13】______evidence that multivitamin use has little or no【C14】______on the risk of common cancers, heart disease or total mortality in elderly women.【C15】______, researchers wondered, "Why do millions of Americans use a daily multivitamin for【C16】______disease prevention when the supporting scientific data are weak?" Some physicians continue to【C17】______them for patients whose diets may have nutritional【C18】______. And since they don’t require a prescription, many people simply【C19】______they are safe. But those assumptions may not be【C20】______, especially if people wind up overdosing on vitamins and minerals, the researchers wrote.
【C8】
选项
A、treating
B、predicting
C、surviving
D、preventing
答案
D
解析
上一句子说明复合维生素并不能有效降低女性罹患癌症的几率,本句句首的Nor一词则表明它对其他疾病也没有预防作用。D项preventing“阻止,预防”代入后表示“在预防心脏病等疾病方面,复合维生素总体上没有帮助”。
