英國倫敦衛生和熱帶醫學學院的研究人員最近發現,有機食品的營養價值和有利健康因素與常規食品并沒有多大差別。他們檢索了過去50年中公開發表過的數萬篇相關文獻,并對其中162篇進行了系統分析;結果發現,多數常見營養成分在有機食品和常規食品中的含量沒有明顯差異。

Organic food has no nutritional or health benefits over ordinary food, according to a major study published Wednesday.

Researchers from the London School of Hygiene2 & Tropical Medicine said consumers were paying higher prices for organic food because of its perceived health benefits, creating a global organic market worth an estimated $48 billion in 2007.

A systematic3 review of 162 scientific papers published in the scientific literature over the last 50 years, however, found there was no significant difference.

"A small number of differences in nutrient4 content were found to exist between organically and conventionally produced foodstuffs5, but these are unlikely to be of any public health relevance," said Alan Dangour, one of the report's authors.

"Our review indicates that there is currently no evidence to support the selection of organically over conventionally produced foods on the basis of nutritional superiority."

The results of research, which was commissioned by the British government's Food Standards Agency, were published in the American Journal of Clinical Nutrition.

Sales of organic food have fallen in some markets, including Britain, as recession has led consumers to cut back on purchases.

The Soil Association said in April that growth in sales of organic products in Britain slowed to just 1.7 percent in 2008, well below the average annual growth rate of 26 percent over the last decade, following a plunge6 in demand at the end of the year.
