The answer is that many of the chemicals that caused worry in earlier decade

10、s have been removed from microwave popcorn, but some critics still are not satisfied. You may consider popcorn to be a low-calorie, high-fiber snack, but microwave popcorn isnt a healthy choice, explains nutrition expert Dan DeFigio. Thats because microwave popcorn bags were coated with perfluorinat

11、ed chemicals(PFCs) to prevent oil substance from leaking out. One particular type of PFC, known as perfluorooctanoic acid(PFOA), has been linked to certain cancers, but the American Cancer Society says the evidence is unsure and more research is being done about this. Nevertheless, in response to co

12、ncerns about PFCs, the U.S. Food and Drug Administration(FDA) worked with popcorn makers back in 2011 to remove PFOA from their packaging. Three more PFCs were banned in the next five years. So todays microwave popcorn doesnt have these chemicals, but critics say that the alternatives could cause pr

13、oblems as the old ones, but less is known about them. Thats not the only problem, however. The chemical that for decades lent buttery deliciousness to popcorn has also been connected in rare cases with major lung damage. Known as diacetyl(二乙酰), its long been a documented problem with workers in popc

14、orn making facilities, but also can be risky for people who just eat the snack a lot. A 2007 study published in the journalCritical Reviewsfound that more than 80 percent of chemical release happened when the bag was opened post-popping. Although diacetyl has been removed from most products, some cr

15、itics claim that the alternative to diacetyl is also harmful. Most of the exposure to diacetyl came from inbreathing rather than eating popcorn. Therefore, experts recommend at least waiting for the bag to cool before you open it to reduce potentially harmful chemical exposure. Better yet, make your

16、 own fresh at home with an air popper. If you like to flavor it, add organic butter or some cheese.1.What can we know about PFOA from the text?A.PFOA has been removed from PFCs.B.PFOA can stop the leak of nutrition.C.PFOA in popcorn bags leads to cancer.D.PFOA doesnt exist in popcorn bags in America

19、opcorn?二、七选五 A calorie is a unit of energy. The calories you see on nutrition labels, however, are actually kilocalories._1_ One kilocalorie is the amount of energy required to heat 1 kilogram of water by 1 degree Celsius. Calories in our food all come from one of the three nutrients: fat, carbohydr

20、ates (碳水化合物) and protein. In 1990, the US government passed an act(法案), which means that before any packaged food in the US hits the shelves, food scientists have to measure its nutrients and calories. One way to do this is with a tool called a calorimeter(热量计)._2_ To use this tool, scientists place

21、 the food in a sealed container surrounded by water and heat it until the food is completely burned off. Scientists then record the rise in water temperature to determine the number of calories in the product._3_ It was developed by the 19th-century US chemist Wilbur Atwater to indirectly estimate o

22、f the number of calories in food products. Calorimeters dont take into account that humans lose some calories through heat and feces (排泄物). Atwaters experiments have found that proteins and carbohydrates each have about 4 calories per gram and fats have 9 calories per gram. _4_ However, some experts

23、 say that the Atwater system is outdated and inaccurate._5_ Besides, it doesnt take into account the digestive process, but assumes complete change of nutrients to energy.A.That is the 4-9-4 system.B.Food scientists also rely on another calculation.C.These calorie counts arent incredibly accurate.D.

24、It was more than likely calculated through the classic Atwater system.E.This tool directly measures the amount of energy that a certain food contains.F.Food packaging always refers to kilocalories, even though it just says calories.G.They say the energy content of certain foods couldnt be accurately
