新奇事件簿 有机食品营养价值更高吗
Scientists have revealed that organic and non-organic food contain pretty much the same amounts and kinds of vitamins and other nutrients. This might be surprising news for those of us who choose to buy organic believing it to be healthier. Researchers from America's Stanford University concluded that there might not be any extra health benefits to buying organic, thus people might be better off saving their money and buying non-organic produce. Lead researcher Dr Crystal Smith-Spangle said there was no difference in the vitamin content in fruit, vegetables, meat and dairy products in organically- and conventionally-produced food. She said the only difference was slightly more phosphorus in the organic products.
科学家发现，有机和无机食物的维他命及其它营养成分含量几乎相同。对于相信有机更健康的顾客而言，这无疑是个惊天消息。斯坦福大学研究人员表示，有机食品无任何额外营养成分，顾客可以省钱购买非有机食品。研究主任克丽丝特尔·史密斯-斯潘格表示，不管是有机还是传统食品，乳制品、水果肉类中的维他命含量无区别。称除了有机中的磷会略多一点，其它没有差别。
Dr Smith-Spangle's review of over 200 different reports on organic food suggests people should perhaps revise their shopping choices, based on the levels of pesticides. Smith Spangler said both organic and conventional foods rarely exceeded the allowable limits for pesticides in the USA. She said the evidence wasn't too clear on whether the difference in pesticides would have an effect on health. She concluded by saying consumers should know there is overwhelming evidence that eating fruit and vegetables is good for your health, so people should eat more fresh produce, whether it is organic or conventional. Organic foods accounted for $31 billion in sales in the USA last year, up from $3.6 billion in 1997.
史密斯-斯潘格博士对200多种有机食品进行了研究，她建议人们根据杀虫剂水平调整购物选择。她称不管是有机还是传统，杀虫剂使用水平几乎不会超过美国规定的限定量。关于杀虫剂使用量会影响食品健康，目前尚无有力证据证明。她总结道，有大量证据表明多吃水果和蔬菜对身体有益，所以不管是有机还是传统，应多吃新鲜食物。去年全美有机销售额为310亿美金，比1997年增长36亿美金。
