盡管阿斯巴甜最近被列為 “可能” 致癌物，但專家并未對建議的阿斯巴甜飲食攝入量做出改變。

The WHO says it has listed aspartame as possibly carcinogenic on the basis of limited evidence that it may increase the risk of liver cancer. This places aspartame in the same hazard classification group as aloe vera and Asian pickled vegetables, but below those deemed probably carcinogenic such as night shift work and eating red meat.

世界衛(wèi)生組織稱，基于有限的證據(jù)表明阿斯巴甜有可能增加罹患肝癌的風(fēng)險(xiǎn)，他們已將阿斯巴甜列為可能致癌物。這使得阿斯巴甜被歸類至與蘆薈和亞洲泡菜相同的危險(xiǎn)物級別，但致癌風(fēng)險(xiǎn)低于被認(rèn)為很可能導(dǎo)致癌癥的行為，比如值夜班和食用紅肉。

The WHO says the current safe daily limits for aspartame are unchanged. That means an adult weighing 11 stone or 70 kilos would need to drink more than four litres of diet soft drink a day to exceed the acceptable daily limit. When asked which was better for you, a can of diet or regular sugary cola, a WHO scientist recommended a third option, water.

世界衛(wèi)生組織表示，目前針對阿斯巴甜的每日最高安全攝入量沒有改變。這意味著一個(gè)體重為11英石、即70公斤的成年人需要飲用超過四升的代糖低脂軟飲才會(huì)超過阿斯巴甜的每日允許攝入量。而當(dāng)被問到無糖可樂和普通的含糖可樂相比，喝哪個(gè)更好時(shí)，世界衛(wèi)生組織的一名科學(xué)家推薦了第三種選擇：水。

閱讀理解：請?jiān)谧x完上文后，回答下列問題。

1. Does aspartame definitely cause cancer? 

2. True or False? Aspartame is more likely to cause cancer than eating red meat. 

3. How much diet soft drink would someone need to drink to go over the daily limit?

4. Which drink did the WHO scientist recommend?

答案

1. Does aspartame definitely cause cancer?

No, it has been listed as possibly carcinogenic – it may increase the possibility of liver cancer, but it might not.

2. True or False? Aspartame is more likely to cause cancer than eating red meat.

False. The article says that aspartame is in a hazard classification group below that of eating red meat.

3. How much diet soft drink would someone need to drink to go over the daily limit?

A 70kg adult would have to drink more than four litres of diet soft drink to go over the daily limit.  

4. Which drink did the WHO scientist recommend? 

The scientist recommended drinking water.
