C Dark chocolate,mainly solid cocoa,is widely believed to be a healthier treat,often credited with benefits like lowering blood pressure and boosting brainpower.These claims are largely linked to flavanols(黄烷醇)，compounds abundant in cocoa.However,a closer look at the scientific evidence suggests that we should be careful about eating dark chocolate. While some short-term studies,frequently funded by chocolate companies,suggested potential advantages,their results have been inconsistent.More importantly,they are too brief to reveal the long-term effects of regular consumption.Observational studies,which simply note correlations(相关性)，found that people who eat more dark chocolate tend to be healthier.But this could be because they often have higher incomes and better overall lifestyles,not because of the chocolate itself. To settle the debate,a big randomized experiment was conducted.It involved older adults who took daily cocoa-flavanol supplements for several years.The findings were clear:the flavanols made no significant difference to the risk of developing heart disease, diabetes,or cancer..There was one positive note-一a reduction in cardiovascular(心血管的) deaths-but this single outcome is not solid proof of benefit. Crucially,obtaining a high share of flavanols from commercial dark chocolate introduces serious disadvantages.To counter cocoa's bitterness,manufacturers add large amounts of sugar.It means a person would also consume a substantial portion of the daily recommended limit of fat,which is known to raise cholesterol()and harm heart health.A far healthier way to get flavanols is from foods like apples,nuts,strawberries, or green tea. Ultimately,the celebrated health benefits of dark chocolate appear to be rooted more in marketing and wishful thinking than in robust science.While enjoying it as an occasional treat is fine,relying on it as a health food is misguided.True wellness comes from a balanced diet rich in various fruits,vegetables,and beans-not from a single,sugary treat. 28.What is a common belief about dark chocolate A.It has inconsistent benefits. B.Its benefits come at a high cost. C.It contributes to physical health. D.Its advantages rely on long-term intake. 29.What is a result of taking in flavanols from dark chocolate A.Faster fat burning. B.Resistance to cholesterol. C.Reduction of cancer risks. D.Increase in sugar consumption. 英语试题第6页共12页
