有機較健康

近年來健康意識抬頭，許多民眾願意多花一點錢，購買價格通常較高的有機食品。不過美國最新研究發現，並沒有證據顯示，有機食品比較健康或營養。

美國史丹佛大學的研究團隊，日前發布研究報告指出，民眾購買有機食品，若是基於健康因素，其實大可不必。

雖然有機蔬果受到殺蟲劑污染的機率比較低，不過這項研究發現，沒必要因此購買有機蔬果。

“我們發現 有機產品被殺蟲劑污染的風險 比傳統蔬果低了30% 不過傳統蔬果的殺蟲劑殘留量 也都低於國家安全標準”

而有人認為有機產品比較營養，但研究發現未必如此。

“其實我們發現的唯一顯著差異是 和傳統同類產品相比 有機雞肉和牛奶的某些 Omega-3脂肪酸含量比較高 不過有數項研究指出 樣品採集季節和牛奶品牌 對脂肪酸含量的影響程度 可能和有機培育的一樣高”

布拉薇塔表示，雖然她參與的研究發現，有機食品未必比較健康，但有機食品還是有其他好處。

Stanford University research doesn’t find organic food more nutritious (2013/06/10)

Growing health consciousness in recent years has led many people to spend a little more on organic food. A new study in the United States has found, however, that there is no evidence that organic food provides more health benefits. 

A research team from Stanford University has found that people who buy organic food expecting it to be beneficial to their health may be wasting their money. 

Some consumers, for example, purchase organically grown fruit and vegetables to avoid exposure to pesticides. But the study found that such purchases may be needlessly cautious.

We found 30 percent lower risk of contamination with pesticides in organic produce when compared to conventional produce. However, the levels of pesticide residues in those foods were well below the national safety limit.

Some consumers also think that organic products are more nutritious, but the study found that this may not necessarily be the case.

Really the only significant difference is that we found higher levels of some of the beneficial Omega-3 fatty acids amongst organic chicken and milk compared to conventional alternatives. However, several of the studies have found that the season of the sampling and the brand of milk were at least as likely to affect the fatty acid levels as to whether they were grown organically or not.

While the Stanford researchers have shown that organic food may not be more nutritious, they do admit that other advantages, such as the lack of pesticide residues and peace of mind, may still be worth the extra cost.
