Organic food has more of the antioxidant (抗氧化剂) compounds linked to better health than regular food, according to the most comprehensive scientific analysis to date. The international team behind the work, led by Prof. Carlo Leifert at Newcastle University, concludes that there are “statistically significant, meaningful” differences, with a range of antioxidants being “substantially higher” in organic food. The increased levels of antioxidants are equivalent to “one to two of the five portions of fruits and vegetables recommended to be consumed daily”.The findings will bring to the boil a long-simmering (炖) row over whether those differences mean organic food is better for people. Tom Sanders, a professor of nutrition at King’s College London, said, “The question is whether they are within natural variation, and whether they are nutritionally relevant.” According to Sanders, Leifert’s work had caused controversy in the past. He added that the research also showed organic cereals have less protein than conventional crops.Leifert’s research, released in the British Journal of Nutrition, are based on an analysis of 343 peer-reviewed studies from around the world – more than ever before – which examine differences between organic and conventional fruits, vegetables and cereals.Leifert and his colleagues conclude that many antioxidants have previously been linked to a reduced risk of chronic diseases such as cardiovascular diseases and certain cancers. But they also note that no long-term studies showing health benefits from a broad organic diet have yet been conducted.The research is certain to encounter criticism. The inclusion of so many studies in the analysis could mean poor quality work distorts the results, although the team claimed that excluding weaker work did not significantly change the outcome. The greatest criticism, however, will be over the suggestions of potential health benefits. An earlier analysis, which took in 223 studies in 2012, found little evidence that organic foods are significantly more nutritious than conventional foods.Sanders said he was not persuaded by the new work. “You are not going to be better nourished if you eat organic food,” he said. “What is most important is what you eat, not whether it’s organic or conventional. It’s whether you eat fruit and vegetables at all.”1. The findings of Leifert’s research indicate that _____________.A) organic food contains higher levels of antioxidants than regular food B) organic fruits have higher levels of antioxidants than organic vegetablesC) simmering makes organic food more nutritious than boilingD) organic food has higher nutritional values than conventional food2. The word “they” in Sanders’ words (Lines 3-4, Para. 2) refers to _____________.A) differences between fruits and vegetablesB) differences between antioxidants and nutritionC) differences between organic food and conventional food D) differences between organic cereals and conventional crops3. According to passage, what will happen as a result of the release of Leifert’s findings?A) More studies will be conducted on the variation of organic food.B) More studies will be conducted on the nutrition of traditional food.C) The dispute over organic food will finally come to an end.D) The dispute over organic food will become more intense. 4. According to Leifert’s research, a diet containing a variety of organic food _____________.A) has not been shown to be clearly beneficial to human health B) has been proved to be able to reduce the risk of chronic diseasesC) has been proved to contain less protein than a conventional dietD) has not been shown to contain more antioxidants than regular food5. It is suggested in the passage that you should _____________ if you want to get better nutrition.A) eat more organic food than conventional food in your mealsB) have a good amount of fruit and vegetables in your daily diet C) include more vegetables than fruits in your daily mealsD) choose fruits and vegetables that contain more antioxidants
