The Organic Foods

Are organically grownfoods the best food choices? The advantages claimed

for such foods over  conventionally grown     and  marketed foodproducts  are

now  being debated. Advocates  of organicfoods -- a term whose meaning

varies greatly --frequently proclaim that such products are safer and more

nutritious than others.

The growing interest ofconsumers in the safety and nutritional quality of

the typical NorthAmerican diet is a         welcomedevelopment. However, much of

this interest has beensparked by sweeping  claims that the foodsupply is          

unsafe or inadequatein  meeting nutritional needs.Although  most of these

claims are not supportedby scientific      evidence, thepreponderance of

written materialadvancing such claims makes it difficult for the general

public to        separate fact from fiction. As a result,claims that eating a

diet consisting entirelyof organically grown foods prevents or cures

disease or provides otherbenefits to health have become widely publicized

and form the basis forfolklore.

Almost daily the publicis besieged by claims for "no-aging" diets, new

vitamins and other wonderfoods. There are numerous unsubstantiatedreports

that natural vitamins aresuperior to synthetic  ones, thatfertilized eggs

are nutritionallysuperior to unfertilized eggs, that untreated grains are

better than fumigatedgrains and the like.

One thing that mostorganically grown food products seem to have in common

is that they cost morethan  conventionally grown foods. Butin  many cases

consumers are  misled if they believe   organic foods  can  maintain    

health  and provide  better  nutritional quality  than conventionally

grown foods. So there isreal cause for concern           ifconsumers particularly

those with limitedincomes, distrust the regular food supply and buy only

expensive      organic foods instead.

綠色食品綠色食品是最佳食物嗎?有人認為綠色食品比通過常規方式生產和銷售的食品 有更多的優越性，然而現在卻有人對此提出異議。  

綠色食品--這一詞的用法非常不統一-- 支持者往往聲稱綠色食品比其它食品更安全，營養價值更高。  北美的消費者們越來越關注

他們的日常飲食是否安全和有營養。 這一發展趨勢是好的。 然而這種關注多半是由一些武 斷的說法引起的，即食物供應不安全或不能提供足夠的營養。  

儘管這些說法多數未被科學 證實，但是由於大量文章支持這一觀點，使得普通群眾難辨真偽。  因此那些認為只食用綠

色食品就能防治疾病或增進健康的觀點便廣為人知，並導致一些不科學的做法和習慣。  公

眾幾乎每天都被"抗衰老"食品、新型維生素以及其它具有神奇功效的食物廣告所包圍。  聲

稱天然維生素優於人造維生素，受精蛋比未受精蛋的營養價值更高，未經薰蒸消毒處理的穀 物比經過處理的好等等諸如此類的報導屢見不鮮，但沒有一篇是經過證實的。

大多數綠色 食品有一共同點，即它們的價格高於以常規方式種植的食物。  但在許多情況下，如果消費

者認為綠色食品能預防疾病且營養價值高於以常規方式生產的食品，那麼他們被誤導了。如

果消費者們，尤其是那些收入有限的消費者們，懷疑傳統食品而只購買更昂貴的綠色食品， 那就值得擔憂了。
