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 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.
有机食品是最佳食物吗？许多人认为有机食品比通过常规方式生产和销售的食品有更多的优越性，这一说法现在正在引起争议。有机食品的支持者往往声称有机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。因此那些认为只要食用有机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。
