职称英语卫生类 AB 级阅读判断例题详解 Red meat links to higher risk of breast cancer Exercise and keeping a healthy weight are two things that doctors say might help women lower their risk of breast cancer Mothers may reduce their risk if they breastfeed for at least four months For older women hormone replacement therapy2 can lower the risk of some other diseases But it has been found to increase the risk of breast cancer So women should consider their choices carefully The same may be said for diet New findings show that younger women who eat a lot of red meat have higher rates of breast cancers called hormone receptor positive 3 The growth is fed by the levels of estrogen or another hormone progesterone in the body Researchers at Brigham Women s Hospital in Boston Massachusetts reported the findings as part of a health study of nurses The researchers followed the health of more than 90 000 women from 1991 to 2003 Those who ate the most red meat ate more than one and one half servings a day A serving was defined as roughly 84 grams Those who ate the least red meat ate less than three servings a week This is what the study found about breast cancers that were hormone receptor positive The women who ate the most red meat were almost two times as likely to get them as the women who ate the least of it Eunyoung Cho the lead author of the report says more research is needed to know the reason for the link But in the past researchers have suggested that three things may play a part One is the way meat is cooked or processed Another is the use of growth hormones in cows And the third is the kind of iron in red meat The study appears in the Archives of Internal Medicine And now we have more to tell you about our subject resveratrol We discussed a study in the United States that found that large amounts of this plant compound helped fat mice live longer The mice were fed much more resveratrol than people could get from red wine one of the foods that contains it Now scientists in France say resveratrol also improves muscle performance again at least in mice They were able to run two times as far in laboratory treadmill tests4 as mice normally could The study at the

provides the first evidence that vitamins could reduce a person s chance of developing cancer A team of Chinese and American scientists did the study They are from American National Cancer Institute and the Cancer Institute of the Chinese Academy of Medical sciences in Beijing The Journal of the National Cancer Institute published the results of the study About thirty thousand people between the ages of 40 to 69 took part in the study They were form the northern central Chinese area of Linxian Most of them took vitamins and minerals every day for five years Linxian was chosen because the people there have an extremely high rate of cancer of stomach and esophagus Researchers believe that fungus and molds in local foods may be partly responsible for the high cancer rate Researchers divided those into eight groups Seven of the groups received different mixtures of vitamins and minerals daily The amounts of the vitamins and minerals were 1 to 2 times greater than what American health officials say is needed The eighth group received sugar pills that had no effect Those who seemed to fain the most received a mixture of a form of vitamin A called carotene vitamin E and the mineral selenium The vitamin and mineral are believed to prevent damage to cells caused by cancer causing substances Researchers reported a 13 percent drop in cancer rates in those who took carotene vitamin E and selenium They also found a 10 percent drop in the number of deaths caused by strokes from bursting blood vessels Scientists warn that it is too soon to know if the effect would be the same among people in other countries They note that the people in Linxian eat foods that lack necessary vitamins and minerals Chinese officials will continue to record the health records of the people in Linxian for many years For now officials reportedly are considering using the results of the study They want to find a way to improved the health of people in Linxian and other small towns in China 1 The results of the new study are unexpected A Right B Wrong C Not Ment
