The Organic Foods
Are organically grown foods the best food choices? The advantages claimed
for such foods over conventionally grown and marketed food products are
now being debated. Advocates of organic foods -- a term whose meaning
varies greatly -- frequently proclaim that such products are safer and more
nutritious than others.
The growing interest of consumers in the safety and nutritional quality of
the typical North American diet is a welcome development. However, much of
this interest has been sparked by sweeping claims that the food supply is
unsafe or inadequate in meeting nutritional needs. Although most of these
claims are not supported by scientific evidence, the preponderance of
written material advancing such claims makes it difficult for the general
public to separate fact from fiction. As a result, claims that eating a
diet consisting entirely of organically grown foods prevents or cures
disease or provides other benefits to health have become widely publicized
and form the basis for folklore.
Almost daily the public is besieged by claims for "no-aging" diets, new
vitamins and other wonder foods. There are numerous unsubstantiated reports
that natural vitamins are superior to synthetic ones, that fertilized eggs
are nutritionally superior to unfertilized eggs, that untreated grains are
better than fumigated grains and the like.
One thing that most organically grown food products seem to have in common
is that they cost more than conventionally grown foods. But in many cases
consumers are misled if they believe organic foods can maintain
health and provide better nutritional quality than conventionally
grown foods. So there is real cause for concern if consumers particularly
those with limited incomes, distrust the regular food supply and buy only
expensive organic foods instead.
绿色食品绿色食品是最佳食物吗?有人认为绿色食品比通过常规方式生产和销售的食品 有更多的优越性,然而现在却有人对此提出异议。
绿色食品--这一词的用法非常不统一-- 支持者往往声称绿色食品比其它食品更安全,营养价值更高。 北美的消费者们越来越关注
他们的日常饮食是否安全和有营养。 这一发展趋势是好的。 然而这种关注多半是由一些武 断的说法引起的,即食物供应不安全或不能提供足够的营养。
尽管这些说法多数未被科学 证实,但是由于大量文章支持这一观点,使得普通群众难辨真伪。 因此那些认为只食用绿
色食品就能防治疾病或增进健康的观点便广为人知,并导致一些不科学的做法和习惯。 公
众几乎每天都被"抗衰老"食品、新型维生素以及其它具有神奇功效的食物广告所包围。 声
称天然维生素优于人造维生素,受精蛋比未受精蛋的营养价值更高,未经薰蒸消毒处理的谷 物比经过处理的好等等诸如此类的报道屡见不鲜,但没有一篇是经过证实的。
大多数绿色 食品有一共同点,即它们的价格高于以常规方式种植的食物。 但在许多情况下,如果消费
者认为绿色食品能预防疾病且营养价值高于以常规方式生产的食品,那么他们被误导了。如
果消费者们,尤其是那些收入有限的消费者们,怀疑传统食品而只购买更昂贵的绿色食品, 那就值得担忧了。
