Genetically engineered crops are safe for humans and animals to eat and have not caused increases in cancer, obesity, gastrointestinal illnesses, Sidney disease, autism or allergies, an exhaustive report from the National Academies of Science released Tuesday found.
Overall, genetically engineered(GE)crops saved farmers in the United States money but didn’t appear to increase crop yields. They have lowered pest populations in some areas, especially in the Midwest but increased the number of herbicide-resistant weeds in others. There’ s also no evidence that GE crops have affected the population of monarch butterflies, the report said.
To gauge whether foods made from genetically modified crops were safe for human consumption, the committee compared disease reports from the United States and Canada, where such crops have been consumed since the mid-1990s, and those in the United Kingdom and western Europe, where they are not widely eaten. No long-term pattern of increase in specific health problems after the introduction of GE foods in the 1990s in the United States and Canada was found.
There was no correlation between obesity or Type II diabetes and the consumption of GE foods. Celiac disease, which makes humans intolerant of gluten, increased in both populations. Patterns in the increase in autism spectrum disorder in children were similar in both the United Kingdom and the United States, the committee reported.
Overall the report concluded that there were no differences in terms of a higher risk to human health between foods made from GE crops and those made from conventionally-bred crops.
Food & Water Watch, a government accountability group in Washington D. C. , said the committee ’ s ties to the biotech industry and other corporations create conflicts of interest and raise questions about the independence of its work. "Critics have long been
marginalized
, "said Wenonah Hauter, the group’ s executive director.
A significant portion of American consumers are concerned about the safety or other effects of foods made with genetically modified crops, often called GMOs for genetically modified organisms. A survey released last year by the NPD Group, a market research firm, found that 57% of Americans were concerned that genetically modified foods posed a health hazard.
The food industry has taken notice. In 2015, Progressive Grocer, a trade publication, reported that total U. S. sales of food and beverage products labeled" non-GMO" reached $ 10 billion during 2014. The National Academies report will likely not sway these consumers, said Phil Lempert, a Los Angeles-based food industry analyst.
" It’ s an emotional issue, it’ s not a science issue, " he said.
What the report from the National Academies of Science finds is got by______.
选项
A、comparing the disease reports from consumers and non-consumers of GE foods
B、estimating the correlation between obesity and the consumption of GE foods
C、differentiating GE crops from conventionally-bred crops
D、doing a market research of health hazards
答案
A
解析
事实细节题。第三段第一句提到,科学院的报告是比较了美国、加拿大(食用转基因食品)和英国、西欧(不怎么食用转基因食品)得出的,所以答案选A项。B项“评估肥胖和转基因食品消费之间的关系”,这是该研究报告的结论之一,不是研究方法;同样,C项也是研究结果之一:D项“对危害健康的因素进行市场研究”文中没有提到,故均排除。
