新奇事件簿 有機食品營養(yǎng)價值更高嗎
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.
科學家發(fā)現，有機和無機食物的維他命及其它營養(yǎng)成分含量幾乎相同。對于相信有機更健康的顧客而言，這無疑是個驚天消息。斯坦福大學研究人員表示，有機食品無任何額外營養(yǎng)成分，顧客可以省錢購買非有機食品。研究主任克麗絲特爾·史密斯-斯潘格表示，不管是有機還是傳統(tǒng)食品，乳制品、水果肉類中的維他命含量無區(qū)別。稱除了有機中的磷會略多一點，其它沒有差別。
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-斯潘格博士對200多種有機食品進行了研究，她建議人們根據殺蟲劑水平調整購物選擇。她稱不管是有機還是傳統(tǒng)，殺蟲劑使用水平幾乎不會超過美國規(guī)定的限定量。關于殺蟲劑使用量會影響食品健康，目前尚無有力證據證明。她總結道，有大量證據表明多吃水果和蔬菜對身體有益，所以不管是有機還是傳統(tǒng)，應多吃新鮮食物。去年全美有機銷售額為310億美金，比1997年增長36億美金。
