綠色食品
《星期日泰晤士報》報道，最新研究顯示，綠色食品(又稱有機食品)的確要比普通食品更有營養，也更有助於人們長壽。
文章說，一直以來，有機食品到底好在哪裡一直是人們爭論的焦點。這次為期4年共耗資1200萬英鎊的研究項目發現，有機食品含有的抗氧化物要比普通食品高40%。
科學家認為，這些抗氧化物能夠有效降低癌症和心臟病的發作。此外，有機食品的鐵、鋅和其他礦物質含量也要比普通食品高。 
文章引述該研究項目負責人的話說，有機食品和普通食品之間的差異非常大，舉例來說，英國營養協會推薦人們每日進食5份水果和蔬菜，但如果你吃的是有機食品，可能一日四份就夠了。
目前，英國營養協會正在對有關報告進行覆核，以決定是否對有關營養建議作相應修改。

THE biggest study into organic food has found that it is more nutritious than ordinary produce and may help to lengthen people's lives.
The evidence from the £12m four-year project will end years of debate and is likely to overturn government advice that eating organic food is no more than a lifestyle choice.
The study found that organic fruit and vegetables contained as much as 40% more antioxidants, which scientists believe can cut the risk of cancer and heart disease, Britain’s biggest killers. They also had higher levels of beneficial minerals such as iron and zinc.
Professor Carlo Leifert, the co-ordinator of the European Union-funded project, said the differences were so marked that organic produce would help to increase the nutrient intake of people not eating the recommended five portions a day of fruit and vegetables. “If you have just 20% more antioxidants and you can’t get your kids to do five a day, then you might just be okay with four a day,” he said.
This weekend the Food Standards Agency confirmed that it was reviewing the evidence before deciding whether to change its advice. Ministers and the agency have said there are no significant differences between organic and ordinary produce.
Researchers grew fruit and vegetables and reared cattle on adjacent organic and nonorganic sites on a 725-acre farm attached to Newcastle University, and at other sites in Europe. They found that levels of antioxidants in milk from organic herds were up to 90% higher than in milk from conventional herds.
As well as finding up to 40% more antioxidants in organic vegetables, they also found that organic tomatoes from Greece had significantly higher levels of antioxidants, including flavo-noids thought to reduce coronary heart disease.
Leifert said the government was wrong about there being no difference between organic and conventional produce. “There is enough evidence now that the level of good things is higher in organics,” he said.
