Text 4 Consuming high-quality plant foods such as whole grains,fruits,vegetables,nuts and legumes may substantially lower risk of developing type 2 diabetes,researchers including one of Indian-origin have claimed."This study highlights that even moderate dietary changes in the direction of a healthful plant-based diet can play a significant role in the prevention of type 2 diabetes,"said Ambika Satija from Harvard T.H.Chan School of Public Health in the US."These findings provide further evidence to support current dietary recommendations for chronic disease prevention,"she said.While previous studies have found links between vegetarian diets and improved health outcomes,including reduced risk of type 2 diabetes,this new study is the first to make distinctions between healthy plant-based diets and less healthy ones that include things like sweetened foods and beverages,which may be detrimental for health.The study also considered the effect of including some animal foods in the diet.Researchers followed more than 200,000 male and female health professionals in the US for more than 20 years who had regularly filled out questionnaires on their diet,lifestyle,medical history,and ncw disease diagnoses as part of three large long-term studies.They evaluated participants'diets using a plant-based diet index in which they assigned plant-derived foods higher scores and animal-derived foods lower scores.The study found that high adherence to a plant-based diet that was low in animal foods was associated with a 20 percent reduced risk of type 2 diabetes compared with low adherence to such a diet,researchers said.Eating a healthy version of a plant-based diet was linked with a 34 per cent lower diabetes risk,while a less healthy version-including foods such as refrned grains,potatoes,and sugar-sweetened beverages-was linked with a 16 per cent increased risk,they said.Even modestly lowering animal food consumption-for example,from 5-6 servings per day to about 4 servings per day-was linked with lower diabetes incidence,the study found."A shift to a dietary pattern higher in healthful plant-based foods,such as vegetables,fruits,whole grains,legumes,nuts,and seeds,and lower in animal-based foods,especially red and processed meats,can confer substantial health benefits in reducing risk of type 2 diabetes,"said Frank Hu from Harvard Chan School.Researchers suggest that healthful plant-based diets could be lowering type 2 diabetes risk because such diets are high in fiber,antioxidants,unsaturated fatty acids,and micronutrients such as magnesium,and are low in saturated fat.Healthy plant foods may also be contributing to a healthy gut microbiome,they said.

We get energy from the foods we eat.Our food supplies energy to keep our organs working.Our food also supplies heat to warm our bodies.The main energy foods are the carbohydrates (碳水化合物).These are the sugars and starches(淀粉). Wheat and rice are rich in starch and many fruits and vegetables contain considerable amount of sugar. Sweets, honey and jam are also rich in sugar.Like carbohydrates, fats are food that provides us with energy. Butter, margarine, certain types of fish, eggs, cooking oils and most red meats are rich in fats. Fats can be stored in various parts of the body as reserves of energy. Because fats in general are slowly digested, they satisfy hunger for long periods.Proteins (蛋白质) are very complex substances. The body needs proteins for the growth of new cells and for the repair and replacement of old cells. Foods rich in proteins are essential to a balanced diet. Milk, some vegetables, meat, chicken, fish, cheese, grains and nuts are some foods rich in proteins.A good diet will contain a variety of foods so that the body contains all the minerals it needs for good health.Vitamins are necessary for the proper working of the body. If we eat a variety of foods, we can be sure of obtaining all the vitamins we need.Water makes up about 70 per cent of the weight of the human body. The average adult needs about two liters of water daily to replace the water the body loses.1.Of the following substances, which are not used as sources of energy by living things?()A. StarchesB. VitaminsC. ProteinsD. Fats2.If equal weight of the following substances is “burned” in the body,A. carbohydratesB. fatsC. vitaminsD. mineral salts3.A boy grows five centimeters a year.The new materialA. fatsB. vitaminsC. proteinsD.carbohydrates4.Which of the following is not true?()A. If a man weighs 150 pounds, 105 pounds are water.B. Apple, butter and meat are rich in proteins.C. A well-balanced diet contains proteins, fats, minerals and vitamins.D. Biscuits, cake and sweets may provide us with energy.5.People can get all the minerals the body needs by().A. having a balanced dietB. drinking more milkC. eating fruits and vegetablesD. having more fish and eggs

Which foods should be eaten to keep us healthy?Let us look at some important vitamins for these answers.Vitamin A helps prevent skin and other tissues from becoming dry.People who do not get enough vitamin A cannot see well in darkness.Vitamin A is found in fish liver oil.It also is in the yellow part of eggs.Sweet potatoes,carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A.Vitamin B-one changes starchy（含淀粉的）foods into energy. It also helps the heart and nervous system work smoothly.Without it,we would be weak and would not grow.Vitamin B-one is found not just in whole grains like brown rice,but also in other foods.These include beans and peas,nuts,and meat and fish.Vitamin B-twelve is needed so folic acid（叶酸）can do its work. Together, they help produce red blood cells.Vitamin B-twelve is found naturally in foods such as eggs,meat,fish and milk products.Folic acid has been shown to prevent physical problems in babies when taken by their mothers during pregnancy.Vitamin B-twelve is found in green leafy vegetables and other foods,like legumes and citrus fruits.In some countries,it is added to products like bread.Vitamin C is needed for strong bones and teeth,and for healthy blood passages.It also helps wounds heal quickly.The body stores little vitamin C.So we must get it every day in foods such as citrus（柑橘类）fruits,tomatoes and uncooked cabbage.Vitamin D increases levels of the element calcium in the blood.Calcium is needed for nerve and muscle cells to work normally.It also is needed to build strong bones.Ultraviolet light from the sun changes a substance in the skin into vitamin D.Fish liver oil also contains vitamin D.Vitamin K is needed for healthy blood.It thickens the blood around a cut to stop bleeding. Vitamin K can be found in pork products,liver and in vegetables like cabbage,kale and spinach. In most countries,vitamin B-twelve is added to products like bread.A:Right B:Wrong C:Not mentioned

Most of us walk and carry items in our hands every day.These are seemingly simple activities that the majority of us don't question.But an international team of researchers,including Dr. Richmond from GW's Columbian College of Arts and Sciences,have discovered that human walking upright, may have originated millions of years ago as an adaptation to carrying scarce（稀有的）,high-quality resources.The team of researchers from the U.S.,England,Japan and Portugal investigated the behavior of modern-day chimpanzees（黑猩猩）as they competed for food resources,in an effort to understand what ecological settings would lead a large ape（类人猿）一one that resembles the 6 million-year old ancestor we shared in common with living chimpanzees一to walk on two legs."These chimpanzees provide a model of the ecological conditions under which our earliest ancestors might have begun walking on two legs",said Dr. Richmond.The research findings suggest that chimpanzees switch to moving on two limbs instead of four in situations where they need to monopolize a resource.Standing on two legs allows them to carry much more at one time because it frees up their hands. Over time , intense bursts of bipedal（二足的）activity may have led to anatomical（解剖学的）changes that in turn became the subject of natural selection where competition for food or other resources was strong.Two studies were conducted by the team in Guinea. The first study was conducted by the team in Kyoto University's "outdoor laboratory" in a natural clearing in Bossou Forest. Researchers allowed the wild chimpanzees access to different combinations of two different types of nut一the oil palm nut,which is naturally widely available,and the coula nut,which is not.The chimpanzees' behavior was monitored in three situations:(a)when only oil palm nuts were available,(b)when a small number of coula nuts were available,and(c)when coula nuts were the majority available resource.When the rare coula nuts were available only in small numbers,the chimpanzees transported more at one time.Similarly,when coula nuts were the majority resource,the chimpanzees ignored the oil palm nuts altogether. The chimpanzees regarded the coula nuts as a more highly-prized resource and competed for them more intensely.In such high-competition settings,the frequency of cases in which the chimpanzees started moving on two legs increased by a factor of four. Not only was it obvious that bipedal movement allowed them to carry more of this precious resource,but also that they were actively trying to move as much as they could in one go by using everything available一even their mouths.The second study,by Kimberley Hockings of Oxford Brookes University,was a 14-month study of Bossou chimpanzees crop-raiding,a situation in which they have to compete for rare and unpredictable resources.Here,35 percent of the chimpanzees activity involved some sort of bipedal movement,and once again,this behavior appeared to be linked to a clear attempt to carry as much as possible at one time.The chimpanzees competed for the coula nuts more intensely.A:Right B:Wrong C:Not mentioned

Napping to a Healthier Heart?1 Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack.The test measures levels of a protein in the blood.The researchers say people with high levels of this protein are at high risk of heart attack,heart failure or stroke.2 Kirsten Bibbins-Domingo of the University of California in San Francisco led the team.For about four years,they studied almost one thousand patients with heart disease.The researchers tested the heart disease patients for a protein called NT-proBNP.Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack,heart failure or stroke.3 The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way.The study involved mostly men,so the researchers could not say for sure that the results are also true for women.They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure.4 Other researchers say more studies are needed to confirm if knowing the protein levels of a heart disease patient should affect that person's treatment.They also would like to know if more aggressive treatment could reduce the patient's chance of a heart attack or stroke.The study appeared in the Journal of the American Medical Association.5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelated study earlier this month in the Archives of Internal Medicine suggests that the answer may be yes.In countries like the United States,afternoon naps are mostly for children.But they are common for adults in Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in the United States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not take naps.6 The researchers say napping may improve heart health by reducing stress.They say the research suggests that naps are especially good for working men.But they say not enough female subjects died during the study to judge the benefits for women.According to some researchers,by measuring the levels of NT-proBNP in the blood people may know______.A:where fewer people die from heart problemB:whether they have the risk of heart attack,heart failure or strokeC:would probably have lower rates of heart diseaseD:how to test a person's NT-proBNP level in the blood by himselfE:his heart muscle would be under pressure in some wayF:that napping is of great benefit to women too

Food FrightExperiments under way in several labs aim to create beneficial types of genetically modified(GM)foods,including starchier potatoes and caffeine-free coffee beans.Genetic engineers are even trying to transfer genes from a cold-water fish to make a frost-resistant tomato.A low-sugar GM strawberry now in the works might one day allow people with health problems such as diabetes to enjoy the little delicious red fruits again.GM beans and grains supercharged with protein might help people at risk of developing kwashiorkor. Kwashiorkor,a disease caused by severe lack of protein,is common in parts of the world where there are severe food shortages.Commenting on GM foods,Jonathon Jones,a British researcher,said,"The future benefits will be enormous,and the best is yet to come."To some people,GM foods are no different from unmodified foods."A tomato is a tomato," said Brian Sansoni,an American food manufacturer.Critics of GM foods challenge Sansoni's opinion.They worry about the harm that GM crops might do to people,other animals,and plants.In a recent lab study conducted at Cornell University,scientists tested pollen made by Bt corn,which makes up one-fourth of the U .S.corn crop.The scientist sprinkled the pollen onto milkweed,a plant that makes a milky juice and is the only known food source of the monarch but-terfly caterpillar. Within four days of munching on the milkweed leaves,almost half of a test group of caterpillars had died."Monarchs are considered to be a flagship species for conservation,"said Cornell researcher Linda Raynor."This is a warning bell."Some insects that are not killed by GM foods might find themselves made stronger. How so? The insecticides used to protect most of today's crops are sprayed on the crops when needed and decay quickly in the environment.But GM plants produce a continuous level of insecticide.Insect species feeding on those crops may develop resistance to the plants and could do so in a hurry, say the critics.Insects may also develop a resistance to the insecticide Bt.At the forum on GM food held last year in Canada,GM crops that have been made resistant to the herbicide might crossbreed with wild plants,creating"superweeds"that could take over whole fields.So where do you stand?Should GM foods be banned in the United States,as they are in parts of Europe?Or do their benefits outweigh any of the risks they might carry? What happens to those insects when not killed by the spray of insecticide?A: They may lose their ability to produce offspring.B: They may have a higher ability to adapt to the environment.C: They move to other fields free from insecticide.D: They never eat again those plants containing insecticide.

Food FrightExperiments under way in several labs aim to create beneficial types of genetically modified(GM)foods,including starchier potatoes and caffeine-free coffee beans.Genetic engineers are even trying to transfer genes from a cold-water fish to make a frost-resistant tomato.A low-sugar GM strawberry now in the works might one day allow people with health problems such as diabetes to enjoy the little delicious red fruits again.GM beans and grains supercharged with protein might help people at risk of developing kwashiorkor. Kwashiorkor,a disease caused by severe lack of protein,is common in parts of the world where there are severe food shortages.Commenting on GM foods,Jonathon Jones,a British researcher,said,"The future benefits will be enormous,and the best is yet to come."To some people,GM foods are no different from unmodified foods."A tomato is a tomato," said Brian Sansoni,an American food manufacturer.Critics of GM foods challenge Sansoni's opinion.They worry about the harm that GM crops might do to people,other animals,and plants.In a recent lab study conducted at Cornell University,scientists tested pollen made by Bt corn,which makes up one-fourth of the U .S.corn crop.The scientist sprinkled the pollen onto milkweed,a plant that makes a milky juice and is the only known food source of the monarch but-terfly caterpillar.

Eating Potatoes Gives Your Immune System a BoostEating potatoes is not only good for bowel health,but also for the whole immune system,especially when they come in the form of a potato salad or eaten cold.In a study on an animal model,researchers in Spain found that pigs fed large quantities of raw potato starch(RPS)not only had a healthier bowel,but also decreased levels of white blood cells,such as leucocytes and lymphocytes in their blood .White blood cells are produced as a result of inflammation or disease, generally when the body is challenged.The general down-regulation of leucocytes observed by the Spanish researchers suggests an overali beneficial effect,a generally more healthy body.The reduction in leucocyte levels was about 15 percent. Lower lymphocyte levels are also indicative of reduced levels of inflammation, but the observed reduction in both lymphocyte density and lymphocyte apoptosis is surprising.In what was the longest study of its kind,pigs were fed RPS over 14 weeks to find out the effect of starch on bowel health."The use of raw potato starch in this experiment is designed to simulate the effects of a diet high in resistant starch,"said study leader Jose Francisco Perez at the Universitat Autonoma de Barcelona,Spain.Humans do not eat raw potatoes,but they do eat a lot of foods that contain resistant starch,such as cold boiled potatoes,legumes,grains,green bananas,pasta and cereals.About 1 0 percent of the starch eaten by human is resistant starch-starch that is not digested in the small intestine and so is shunted into the large intestine where it ferments .Starch consumption is thought to reduce the risk of large bowel cancer and may also have an effect on irritable bowel syndrome (IBS).Immunology expert Lena Ohman's team previously found that the overall lymphocyte levels do not vary for IBS patients,but that lymphocytes are transferred from the peripheral blood to the gut,which support the hypothesis of IBS being at least partially an inflammatory disorder. She says the decrease in lymphocytes observed by the Spanish is therefore interesting,and a diet of resistant starch may be worth trying in lBS patients.Ohman is currently at the Department of Internal Medicine,Goteborg University,Sweden.The study is published in the journal Chemistry and Industry,the magazine of the SCI. All of the following foods are rich in resistant starch EXCEPT______.A: pastaB: grainsC: legumesD: vegetables

Text 4 Consuming high-quality plant foods such as whole grains,fruits,vegetables,nuts and legumes may substantially lower risk of developing type 2 diabetes,researchers including one of Indian-origin have claimed."This study highlights that even moderate dietary changes in the direction of a healthful plant-based diet can play a significant role in the prevention of type 2 diabetes,"said Ambika Satija from Harvard T.H.Chan School of Public Health in the US."These findings provide further evidence to support current dietary recommendations for chronic disease prevention,"she said.While previous studies have found links between vegetarian diets and improved health outcomes,including reduced risk of type 2 diabetes,this new study is the first to make distinctions between healthy plant-based diets and less healthy ones that include things like sweetened foods and beverages,which may be detrimental for health.The study also considered the effect of including some animal foods in the diet.Researchers followed more than 200,000 male and female health professionals in the US for more than 20 years who had regularly filled out questionnaires on their diet,lifestyle,medical history,and ncw disease diagnoses as part of three large long-term studies.They evaluated participants'diets using a plant-based diet index in which they assigned plant-derived foods higher scores and animal-derived foods lower scores.The study found that high adherence to a plant-based diet that was low in animal foods was associated with a 20 percent reduced risk of type 2 diabetes compared with low adherence to such a diet,researchers said.Eating a healthy version of a plant-based diet was linked with a 34 per cent lower diabetes risk,while a less healthy version-including foods such as refrned grains,potatoes,and sugar-sweetened beverages-was linked with a 16 per cent increased risk,they said.Even modestly lowering animal food consumption-for example,from 5-6 servings per day to about 4 servings per day-was linked with lower diabetes incidence,the study found."A shift to a dietary pattern higher in healthful plant-based foods,such as vegetables,fruits,whole grains,legumes,nuts,and seeds,and lower in animal-based foods,especially red and processed meats,can confer substantial health benefits in reducing risk of type 2 diabetes,"said Frank Hu from Harvard Chan School.Researchers suggest that healthful plant-based diets could be lowering type 2 diabetes risk because such diets are high in fiber,antioxidants,unsaturated fatty acids,and micronutrients such as magnesium,and are low in saturated fat.Healthy plant foods may also be contributing to a healthy gut microbiome,they said.
From the new study,we can infer that_____A.sweet fruit juice and beverages are beneficial to our health
B.animal foods should not be included in our diet for the sake of health
