问题     Protecting the heart, warding off cancer, easing the pain of arthritis -- the list of Vitamin E’s possible benefits keeps getting longer. Now, because of two new studies, some researchers say the nutrient is so critical for older people that everyone over 65 should consider taking a daily supplement.
    The latest finding comes from nutrition and immunology respected: Vitamin E boosts the immune system in older people. In an eight-month study of 88 seniors, the scientists found that those taking at least 200 international units of Vitamin E daily had stronger immune responses than those taking little or none. Alzheimer’s disease. Researchers tracked 341 moderately senile patients. Those who popped 2,000 IU of Vitamin E took seven months longer to reach an advanced stage of the disease.
    Rangit Kumar Chandra, a Vitamin E researcher at Memorial University of Newfoundland, Canada, says more studies are needed to learn who can benefit most and at what dose. Vitamin E thins the blood, so high doses can cause bleeding in people who also take blood thinning drags, even aspirin. Individuals with serious conditions should consult their doctors. But most people over 65, Chandra says, can take up to 200 IU with no side effects and great benefits.
Which of the following is NOT true?

选项 A、People taking 200 IU got bigger immune defenses than the ones who got only 60 IU.
B、Research has found Vitamin E delays the progression of Alzheimer’s disease.
C、Most of us can get sufficient Vitamin E from diet.
D、It’s important to remember when taking Vitamin E: more may not be better.

答案C

解析 本题为事实题。A项意为“服用200国际单位的维生素E的人,其免疫系统比那些只服 60国际单位的人得到了更大的增强”,从第二段最后一句我们可以推断其正确性;B项意为“研究人员已经发现维生素E可以缓解老年痴呆症的恶化”,从第三段中我们可以找出依据;D项意为“服用维生素E务必记住:并非越多越好”,由第二段最后一句及第四段中维生素对血液稀释的副作用,可以推断其正确性;而C项意为“我们大部分人都可以从饮食中获得足够的维生素E”,此项文中没有提及。
