单选题Diabetes Diabetes is a condition where blood glucose (sugar)levels are poorly controlled. Latest figures show that over 2 million people in the UK have diabetes, and an estimated 1 million people are undiagnosed and don't realize they have diabetes. If you' re living with diabetes you need to reduce your risk of developing associated diseases such as coronary heart disease, kidney and eye disease. This means losing weight, keeping your blood pressure and blood glucose as near normal as possible and having your cholesterol and tri - glycerides checked regularly. By choosing to eat a healthy balanced diet you'll already have started to manage diabetes by helping to control your blood glucose levels, blood fats and blood pressure. It will also help to regulate your weight. Even small weight losses lead to surprisingly big reductions in the risk of diabetes and will also reduce your risk of heart disease, high blood pressure and stroke. Finding the balance between the amount of carbohydrates and fat is important. Cut down on the amount of fat you eat - particularly saturated (animal)fats, as this type of fat is linked to heart disease. Choose monounsaturated fats, e. g. olive oil and rapeseed oil. Aim to eat a portion of oily fish at least twice a week. Eat regular meals based on starchy carbohydrate foods - such as bread, pasta, chapattis, potatoes, yam, noodles, rice and cereals. Include plenty of fresh fruits and vegetables. Whatever your weight, being fit and active reduces your risk of diabetes. Physical activity, when combined with a healthy balanced diet, will help you to manage your diabetes and prevent long - term complications. In recent years great strides have been made in the treatment of diabetes, but no one can deny the impact a diagnosis of diabetes can have on individuals. It' s important that you begin to make these changes to your diet as soon as you' re diagnosed. Managing diabetes is a daily challenge and carries its own health risks, especially the increased likelihood of heart disease.

单选题{{B}}第三篇{{/B}} {{B}}Warm People Likely to Keep Cold at Bay{{/B}} Staying positive through the cold season could be your best defense against getting ill, new study findings suggest. In an experiment that exposed healthy volunteers to a cold or flu virus, researchers found that people with a generally sunny disposition were less likely to fall ill. The findings, published in the journal Psychosomatic Medicine, build on evidence that a "positive emotional style" can help ward off the common cold and other illnesses. Researchers believe the reasons may be both objective as in happiness boosting immune function and subjective as in happy people being less troubled by a scratchy throat or runny nose. "People with a positive emotional style may have different immune responses to the virus," explained lead study author Dr Sheldon Cohen of Carnegie Mellon University in Pittsburgh. "And when they do get a cold, they may interpret their illness as being less severe." Cohen and his colleagues had bound in a previous study that happier people seemed less susceptible to catching a cold, but some questions remained as to whether the emotional trait itself had the effect. For the new study, the researchers had 193 healthy adults complete standard measures of personality traits, self-perceived health and emotional "style". Those who tended to be happy, energetic and easy-going were judged as having a positive emotional style, while those who were often unhappy, tense and hostile had a negative style. The researchers gave them nasal drops containing either a cold virus or a particular flu virus. Over the next six days, the volunteers reported on any aches, pains, sneezing or congestion they had, while the researchers collected objective data, like daily mucus production. Cohen and his colleagues found that based on objective measures of nasal woes, happy people were less likely to develop a cold.

单选题{{B}}第二篇{{/B}} Fortunately there are still a few tasty things for us to enjoy in relative security. Their numbers, however, are depleted almost daily, it seems, by ruthless proclaimations from the ever-watchful Food and Drug Administration and its allies, our doctors, The latest felon(重罪犯) to face prosecution is the salt of life, sodium chloride(食盐). Apparently, overuse of salt causes high blood pressure and hypertension, the cause of half the deaths in the United States every year. A few years ago the anti-salt campaigners raised such an uproar that salt was banned from baby food. Currently pressure is being applied to food manufacturers to oblige them to label their products to show sodium content. Because doing so would cost manufacturers money, they argue that they have no idea how much salt remains on such things as potato chips and how much sticks to the bag. Furthermore, salt isn't the only harmful ingredient in food. If the manufacturer has to provide sodium content, why not require him to list every ingredient and specify which are harmful to our health? Cigarettes have a warning printed on them. Shouldn't the same type of warning appear on canned foods that are notoriously over- salted? There are endless ifs and buts in the controversy, but the most telling of these is the questionable proof of salt's effect upon the blood pressure. True, people who cut their salt intake lowered their blood pressure, but where is the scientific proof that something other than salt didn't do the trick? The most common means of providing dubious proof that salt causes hypertension is to compare societies that use little salt with those that use mountains of salt in their daily diets. Which group has the higher rate of hypertension? Whose blood pressure is lower? What happens when salt is introduced into a group where salt is a novelty? Does the blood pressure rise significantly? Studies of the Japanese indicate that as the world's greatest salters, they suffer the most from hypertension. On the other hand, the simple, salt-free cooking of several tribes in the Solomon Islands has kept older tribesmen and women from developing hypertension and high blood pressure, ailments traditionally killing their peers in America. No account is taken of the effects of inflation, recession, pollution, crime, and sundry (多种多样的) other ills to which Americans, unlike people on primitive islands, are exposed. To salt or not to salt? That is the question. Now that the question has arisen, it must not be treated with levity(轻率) but, rather, with searching scientific investigation so that those of us who are preoccupied with both savory(薄荷) food and longevity may decide which of the two is worth its salt.

单选题Sleep Problems Plague the Older Set Older Americans often have difficulty getting a good night"s rest. It"s a huge quality of life problem, experts say, because contrary to popular belief, seniors require about the same amount of sleep as younger adults. "Sleep problems and sleep disorders are not an inherent (固有的) part of aging," said Dr. Harrison G. Bloom, an associate clinical professor of geriatrics (老年病学) and medicine at the Mount Sinai School of Medicine in New York City. "It"s pretty much of a myth that older people need less sleep than younger people." Yet, in a study published recently in The American Journal of Medicine, researchers found that more than half of older Americans have problems getting the sleep they need. Older people tend to have "sleep fragmentation," meaning they wake up more often during the night, said study author Dr. Julie Gammck, an assistant professor of medicine in the Division of Geriatric Medicine at St. Louis University. They also seem to get less "REM" sleep, the type of sleep during which rapid eye movement occurs, Bloom added. It"s unclear what role these naturally occurring changes in sleep patterns have on person"s quality of life, Bloom said. "What is important, though, is that older people often have actual sleep disorders and problems with sleep," he said. And, experts say, there is usually more than one cause. "Sleep trouble in older adults is typically associated with acute and chronic illnesses, including specific sleep disorders like sleep apnea (呼吸暂停) and restless leg syndrome that appear with greater frequency in older populations," said Michael Vitriol, a professor of psychiatry and behavioral sciences and associate director of the University of Washington"s Northwest Geriatric Education Center. Taking multiple medications, as many older people do, can also lead to fatigue a "hypersomnia" or being tired all the time, Bloom added. Another big problem, he noted, is depression and anxiety. "Those are very commonly associated with sleep problems." Despite the prevalence (流行) of sleep difficulties in older adults, many patients aren"t getting the help they need. As a result, problems like insomnia (失眠), restless leg syndrome and sleep apnea are under-diagnosed and under-treated, Bloom said.
