5、根据下面内容,回答题。
The Heart Assoeiation’s Junk Science Diet
A.A recent Cambridge University analysisof 76 studies involving more than 650,000 peopleconcluded,“The current evidence does not clearlysupport guidelines that low consumption of total Saturated fats.“Yet the American Heart Association(Arial,in its most recent dietary guidelines,heldfast to the idea that we must A.l eat low.fat diets for optimal  hearthealth.It’s a stance that—at the very best—is controversial,and at worst is dead wrong.As a practicing cardiologist(心脏病学家)for more than three decades,I agree with the latte—it’s dead wrong.Whydoes the AHA cling to recommendations that fly in the face of scientificevidence?
B.What I discovered was both eye.opening and disturbing.The AHA not only ignored all the other risk factors for heart disease,but it appointed someone with ties to Big Food and bizarrescientific beliefs to lead the guideline-writing panel—just the type of thing that undermines the public’s confidence in the medical community.The AHA guidelines warrant that saturated fat make up no more than 5 to 6 percent of daily calories for adults because this will lower “bad” cholesterol(胆固醇).And,for those people who need blood pressure control,the guidelines A.so suggest lowering sodium(salt)intake to no more than a teaspoon(2,300 mg)daily.Despite many other known risk factors for heart disease,salt and fat were,astonishingly,the only two considered by the AHA panel writing the guidelines.There are many other recognized risk factors the AHA ignored,including blood sugar level,low “good” cholesterol,insulin(胰岛素)levels,and body weight—an of these are influenced by diet.
C.In fact,mostpeople who have heart attacks don’t have elevations in bad cholesterol.They are much  more likely tohave metabolic syndrome(新陈代谢综合征)—a condition that putsyou at high risk for diabetes and heart disease.Interestinglyenough,blood triglycerides(甘油三脂)do not go up with eating fat—they go up if you eat a diet high inprocessed grains,starches,andsugar.Unfortunately for the proponents ofhigh-carbohydrate(糖类)diets,highblood triglycerides are a major risk factor for heart disease.In addition.low fat/highcarb diets lower protective “good”cholesterol and raiseinsulin.
These diets are involved in the development of diabetes.which is a powerful risk factor for developing heart disease.
Heart Cheek Program’s contribution
D.The writers of the 2013 statinguidelines based their recommendations on studies that looked at the reductionin the risk of events like heart attacks in people treated with statins.compared to people on a placebo(安慰剂).The AHAdietary guidelines do not cite any diet studies that looked at whether followinga specific diet lowered the risk of developing heart events—yet they are givingdietary advice.Why?There mightbe two plausible reasons.One is the AHA's moneymaking “HeartCheck Program.”The second is the conflict of interestof Robert Eckel—the co-chair of the panel that wrote the guidelines.
E.Forty.fivepercent of these “heart healthy” foods—over 400 of them—are meat:92 are processed meats—which have been shown to have either neutralor negative effects on heart health.Even more problematicare the foods containing added sugar.The AHA recommendsthat women consume less
than 6 teaspoons(100 calories)of sugar a day and less than 9 teaspoons(150caories)for men.Yet there areitems that get the nod of approval.from the HeartCheck program despite being near or at the sugar limit.1ikeBruce’s Yams Candied Sweet Potatoes and Healthy Choice Salisbury Steak.
F.Until this year,Heart Check approved many foods with trans-fats,which raise bad cholesterol and lower good cholesterol,among other harmful effects on health,like increasing inflammation(发炎)and the laying down of calciumin arteries(动脉).
G.Like the dietary guidelines,the AHA Heart Check Program appears to address only the effect of foods on cholesterol level and blood pressure.Meanwhile,since the 1 970s,our yearly sugarconsumption has increased quickly along with the incidence of diabetes and obesity.This brings us to Dr.Robert
H.Eckel,theco-chair of the Working Group.He is a consultant for Foodminds,which specializes “in food,beverage,nutrition,health and wellness.”Foodminds works with more than 30 leadingfood,beverage,and nutrition tooffer a “one stop shop of…consulting…to guide food and beverage companies innavigating the complexities around the upcoming FDA Nutrition Facts labeloverhaul.”In other words.Foodmindsis a lobbying firm for “Big Food.”
Creationist’s coming
H.And then there is this:Dr.Eckeldescribes himself as “a scientist and professing six.daycreationist and a member of the technical advisory board of the Institute forCreation Research…”Many scientists are religious.This isnot to question Dr.Eckel’s religious beliefs.but to question his ability to think sciemifically.He believes there is scientific proof that the world was created insix days and mat evolution does not exist.This shouldat least raise eyebrows when the co-chair of an influential panel charged withgiving scientifically sound dietary advice has a financial conflict of interestand proselytizes for beliefs that are anti.scientific.
I.The American people should beable to trust that only impartial scientists write guidelines.We should be confident that those experts are not working to advancecorporate interests and that they do not espouse beliefs that are well outsidethe scientific mainstream.An avowed creationist who consults for a food lobby hardly seems an appropriate choice to fulfill these criteria.For the last several decades,the AHA has promoted a low-fat high-carbohydrate diet as acornerstone of heart health.It has taken a very public position that saturated fats are a major driver of heart disease risk and the mounting tide of evidence that this is dead wrong must put it in a very uncomfortable position.And yet a fundamental requirement of science--as opposed to propaganda--is that when evidence that contradicts a hypothesis is replicated over and over again,that hypothesis must be abandoned.
J.The idea that eating high amounts of saturated fat causes hardening of the arteries—the so.Called “diet-heart hypothesis—deserves to be jettisoned along with other discredited belief systems.Creationism comes tomind.Will the AHA step up to the plate?
注意:此部分试题请在答题卡2上作答。
It is fun that blood triglycerides won’t rise when you eat fat,but go up with eating other sugar and starches.
