No Sweet Talk About SugarSugar's proponents call it quick energy, opponents say it's empty calories (卡路里) 。 But to the average person, who consumes a quarter of a pound of it each day, sugar is mostly an irresistibly good taste.In fact, people seem to have an innate "sweet tooth."Human societies have long equated sweetness with goodness - sweet mystery of life, sweet smell of success, sweetheart - and that enhances (增强;提高) the attraction.But in recent years, sugar has also been singled out as a potential enemy of the healthy life.Cited for such evils as distracting youngsters from more nutritious (营养的) foodstuffs, enhancing obesity (肥胖), ruining teeth and causing diabetes(糖尿病), it has become the most maligned (恶毒的) of the main components of our diet.Sugar, like starch, is a carbohydrate (碳水化合物).Its many types include sucrose (table sugar refined from sugarcane or beets), lactose (milk sugar), fructose (fruit sugar), glucose (blood sugar), dextrose (右旋糖), maltose(麦芽糖) and galactose (半乳糖).Seventy percent of the sugar in the labels on all the packaged products in your pantry (食品室) and see how many list sugar (or corn syrup) as a main ingredient (成分) 。Early this century, the average North American consumed about 76 pounds of refined sugar a year, but starches formed two thirds of his dietary carbohydrates.Today, per-capita refined sugar consumption hovers around 95 pounds, and all types of sugar represent more than half the carbohydrate calories.But in relying on sucrose-sweetened processed foods as a main carbohydrate source, we may miss the essential nutrients - fiber, vitamins and minerals - found in other carbohydrate foods like fruits, vegetables and breads.The body has no physiological need for sucrose that cannot be satisfied by other, more nutritious foods.The body can convert starches to sugar, or use the sugar in fruits and vegetables for energy.In fact, nutrition experts say that even the purported (传说的) need for sugar as quick energy is a myth except in a few rare situations, such as a diabetic in insulin shock.During exercise, the body calls upon its reserve of glycogen (肝糖) (and, if that runs low, fatty acids from the breakdown of triglycerides) to supply the muscles with needed energy.If you eat sugar before exercising, your body simply stores it.As for sugar's reputed adverse (不利的) health effects, the following can be said on the basis of available evidence:Obesity, Sugar supplies four calories per gram - about the same as protein and less half that of fat.Excess caloric intake, not sugar, causes obesity.But since calories can be highly concentrated in sugar-sweetened foods, you may eat many more calories than you need of such foods before you feel full or even realize how much you consumed.Tooth decay.Sugar definitely promotes the development of dental caries.Bacteria in the mouth digest (消化) the sugar on tooth surfaces, and produce acid which eats away the enamel (珐琅).It is the time sugar remains on the teeth, rather than the amount eaten, that makes the difference.To reduce the risk of decay, dentists recommend rinsing your mouth or brushing you teeth after consuming anything sweet, and avoiding sweets between meals.Diabetes.In diabetes, the pancreas (胰腺) fails to produce enough insulin to clear the blood of excess glucose.Thus, diabetics must curb their intake of sweets lest their blood-sugar levels rise dangerously high.But the important factor in diabetes is controlling body weight.Heart Disease.The theory that sugar is an important factor in heart disease does not have wide support among experts, who say that fats and cholesterol (胆固醇) are the more likely culprits (罪魁祸首).Some people have a tendency to develop high blood levels of fatty substances called triglycerides, which may promote atherosclerosis (动脉硬化).They are often advised to reduce their sugar intake, but losing weight is more important.Diets free of sucrose can lower abnormally high triglyceride levels, but they have been found to have little or no effect on triglyceride levels that are acceptable in the first place.1、What does the word "innate" mean?()A、born withB、implantedC、badD、healthy2、Which of the following statements is NOT true?()A、There are many types of sugar such as sucrose, lactose, fructose, etc.B、Sugar can cause many health problems such as obesity, tooth decay and diabetes.C、Sugar is not nutritious because it doesn't contain fiber, vitamin and mineral.D、Sugar is physiologically needed by the body and can not be substituted by other substance.3、"Curb their intake of sweets" can also be referred to as()their intake of sweets.A、increaseB、decreaseC、limitD、take4、Based on the ideas presented in the passage we can conclude that ().A、there is not available evidence to show sugar's bad effectsB、if you eat a lot of sweet food, you may suffer from obesity, because such food contains a lot of caloriesC、to limit sugar intake is the most important thing for the atherosclerosis patientD、most experts believe that sugar can cause heart disease5、From the passage, we know().A、sugar eats away the enamel, thus causing tooth decayB、the cause for diabetes is the excessive intake of sugarC、fats and cholesterol have nothing to do with heart diseaseD、high level triglycerides may increase the chances of atherosclerosis

Free Statins with Fast Food could Neutralize Heart RiskFast food outlets could provide statin drugs free of1so that customers can reduce the heart disease dangers of fatty food,researchers at Imperial College London 2in a new study.Statins reduce the3of unhealthy“LDL” cholesterol in the blood. A wealth of trial data has proven them to be highly effective at lowering a person's heart attack4.In a paper published in the American Journal of Cardiology,Dr Darrel Francis and colleagues calculate that the reduction in heart attack risk offered by a statin is5to offset the increase in heart attack risk from6a cheeseburger and drinking a milkshake.Dr Francis,from the National Heart and Lung Institute at Imperial College London,who is the senior author of the study,said:“Statins don't cut out all of the7effects of cheeseburgers and French fries. It's better to avoid fatty food altogether. But we've worked out that in terms of your8of having a heart attack. Taking a statin can reduce your risk to more or less the same9 as a fast food meal increases it.”“It's ironic that people are free to take as many unhealthy condi-ments in fast food outlets as they10,but statins,which are beneficial to heart health,have to be prescribed. It makes sense to make risk-reducing statins available just as easily as the unhealthy condiments that are 11 free of charge. It would cost less than 5 pence per/u>12一not much different to a sachet of sugar.”Dr Francis said.When people engage in risky behaviours like driving or smoking,they're encouraged to take13that lower their risk,like14a seatbelt or choosing cigarettes with filters.Taking a statin is a rational way of15some of the risks of eating a fatty meal.7._________A: unhealthy B: strong C: different D: doubtful

Deaths Associated with Sugary Soft DrinksSugar-sweetened sodas,sports drinks and fruit drinks may be associated with about 180,000 deaths around the world each year,according to a recent research.Sugar-sweetened beverages are consumed throughout the world,and contribute to excess body weight,which increases the risk of developing diabetes,cardiovascular diseases and some cancers. Using data collected as part of the 2010 Global Burden of Diseases Study,the researchers linked intake of sugar-sweetened beverages to 133,,000 diabetes deaths,44,000 deaths from cardiovascular diseases and 6,000 cancer deaths.Seventy-eight percent of these deaths due to over-consuming sugary drinks were in low and middle-income countries,rather than high-income countries."In the U.S.,our research shows that about 25,000 deaths in 2010 were linked to drinking sugar-sweetened beverages,"said Mr. Singh,a postdoctoral research fellow at the Harvard School of Public Health in Boston.Of nine world regions,Latin America/Caribbean had the most diabetes deaths(38,000)related to the consumption of sugar-sweetened beverages in 2010.Japan,one of the countries with lowest per-capita consumption of sugary beverages in the world,had the lowest death rate associated with the consumption of sugary beverages,at about 10 deaths due to per million adults."Because we were focused on deaths due to chronic diseases,our study focused on adults.Future research should assess the amount of sugary beverage consumption in children across the world and how this affects their current and future health,"Singh said.The American Heart Association recommends adults consume no more than 450 calories per week,from sugar-sweetened beverages,based on a 2,000 calorie diet and offers tips to help you make better lifestyle choices and eat healthier.The study focused on the entire population.A:Right B:Wrong C:Not mentioned

The Tough Grass That Sweetens Our LivesSugar cane was once a wild grass that grew in New Guinea and was used by local people for roofing their houses and fencing their gardens. Gradually a different variety evolved which contained sucrose（蔗糖） and was chewed on for its sweet taste.Over time,sugar cane became a highly valuable commercial plant,grown throughout the world.___________(46)Sugar became a vital ingredient in all kinds of things , from confectionery（糖果点心）to medicine, and,as the demand for sugar grew,the industry became larger and more profitable.________(47)Many crops withered（枯萎）and died,despite growers'attempts to save them,and there were fears that the health of the plant would continue to deteriorate.In the 1960s,scientists working in Barbados looked for ways to make the commercial species stronger and more able to resist disease.They experimented with breeding programmes,mixing genes from the wild species of sugar cane,which tends to be tougher,with genes from the more delicate,commercial type. ________(48)This sugar cane is not yet ready to be sold commercially,but when this happens,it is expected to be incredibly profitable for the industry.__________(49)Brazil,which produces one quarter of the world's sugar,has coordinated an interna-tional project under Professor Paulo Arrudo of the Universidade Estaudual de Campinas in Sao Paulo.Teamsof experts have worked with him to discover more about which parts of the genetic structure of the plant are important for the production of sugar and its overall health.Despite all the research,however,we still do not fully understand how the genes act in sugar cane._________(50)This gene is particularly exciting because it makes the plant resistant to rust,a disease which probably originated in India,but is now capable of infecting sugar cane across the world.Scientists believe they will eventually be able to grow a plant which cannot be destroyed by rust._________（46）A:Eventually,a commercial plant was developed which was 5 percent sweeter than before,but also much stronger and less likely to die from disease.B:Unfortunately,however,the plant started to become weaker and more prone to disease.C: One major gene has been identified by Dr Angelique D, Hont and her team in Montpelier, France.D:The majority of the world's sugar now comes from this particular commercial species.E:Sugar cane is now much more vigorous and the supply of sugar is therefore more guaranteed.F: Since the 1960s,scientists have been analysing the mysteries of the sugar cane'S genetic code.
