Sugar Accelerate the Process of Aging
Sugar is widely used in our daily life to make food and drinks sweet,though too much intake of it may lead to diabetes.However,today's study found it also makes people get old faster. Rats that eat high levels of a natural sugar known as fructose seem to age faster than other rats.And the same could be true for people who eat too much sweet junk food,said Israeli researchers.
Fructose,a substance found naturally in honey and fruit,is used widely in foods ranging from soft drinks to yogurt. But while its sweet taste is popular,the sugar could cause wrinkles and health problems,the researchers said.Dr. Moshe Werman and Boaz Levi of the Technion-Israel Institute of Technology fed large amounts of fructose to laboratory rats.Writing in the Journal of Nutrition,they said the fructose-fed rats showed changes in the collagen of their skin and bones.
Collagen,a fibrous protein found in connective tissue,bone and cartilage,basically holds the body together. The loss of collagen is what causes sagging and deep wrinkles in older people.
The process affected,Werman's team said,is known as"cross linking"."Too much crosslinking reduces elasticity and makes the skin stiff and rigid,and these are the conditions that encourage wrinkled skin,"Werman said in a statement. He said the same could be true of people, although this has not been shown."Americans are eating more and more processed foods such as carbonated drinks,baked goods,canned fruits,jams and dairy products that contain fructose," Werman said.Other studies have shown that high fructose intake can affect how the body handles glucose and increases insulin resistance一which can both be important measures of the tendency toward diabetes.
The rats Werman worked with were fed much more than the average adult person might eat in a day,which is standard in such experiments.The rats were 12.5 grams of fructose per kg(2.2 pounds)of weight every day for a year. To compare,a person weighing 154 pounds(70kg)who drinks a quart(liter)of cola consumes about 60 grams of fructose,or 0.8 grams per kg of body weight.
选项
According to the passage,people who eat too much sweet junk food will_______.A:slow down their process of agingB:more likely to get diabetesC:get heavier than othersD:age faster than average people
答案
D
解析
本题是细节考查题。题干是:根据这篇短文,食用过多甜味垃圾食品的人会______。选D的依据是第一段第三句:" Rats that eat high levels of a natural sugar known as fructose seem to age faster than other rats一and the same could be true for people who eat too much sweet junk food , said Israeli researchers.”大量摄取一种叫做果糖的天然糖的老鼠,似乎比其他老鼠衰老得更快。对甜食吃得太多的人来说,情况也可能会是如此。所以,选项D比大多数人老得快,符合原文意思,是正确答案。 本题是细节考查题。题干是:人们在哪里更容易找到果糖?选B的依据是第二段第一句:"Fructose...is used widely in foods ranging from soft drinks to yogurt.”果糖自然存在于蜂蜜和水果中,被广泛用于从饮料到酸奶的各种食品中。所以选项B软饮料和酸奶,是正确答案。 本题考查上下文理解能力。题干是:导致老年人皮肤松弛和深度皱纹的原因是什么?依据是第三段第二句:" The loss of collagen is what causes sagging and deep wrinkies in older people.”胶原蛋白的丧失是导致老年人皮肤松弛和深度皱纹的原因。所以选项A 胶原蛋白的丧失,是正确答案。 本题考查考生对上下文的理解能力。题干是:过多的交叉相连会导致什么?选择C为正确答案,依据是第四段第二句:" Too much cross-linking reduces elasticity and makes the skin stiff and rigid...”太多的交叉相连就会使皮肤降低弹性、发生硬化,所以选项C 皮肤降低弹性、发生硬化,是正确答案。 本题是主旨考查题。题干是:你认为作者写这篇文章可能的目的是什么?选B的依据是题目“糖加快人的衰老进程”以及作者在文章中所分析的各种恶果。所以选项 B建议人们吃适量的糖,防止快速衰老,与原文主旨相符。
