As we have seen, pesticide and nitrate levels are lower,
正如我們所見殺蟲劑和硝酸鹽的含量都較低，
but E-coli contamination of fruits and vegetables before market preparation is much higher.
但是在進入市場之前，水果和蔬菜遭受大腸桿菌污染的可能性更大
Also, the synthetic chemicals used by organic farmers have health risks of their own
同時，有機農(nóng)場中用到的合成化學物質也會對健康造成風險，
and some allow chemicals containing copper and magnesium sulfates,
一些化學物質含有銅和鎂還有硫酸鹽，
which can be fatal if ingested directly.
這些物質如果直接食用會威脅人的生命，
The FDA and USDA provide strict regulations for pesticides, herbicides,
農(nóng)業(yè)部和環(huán)保局對傳統(tǒng)農(nóng)業(yè)生產(chǎn)中所用到的殺蟲劑，除草劑
and other chemicals used in conventional farming.
等化學物質有嚴格的規(guī)定
Bio-solids used in agricultural fertilizer must be processed using stringent,certified procedures
農(nóng)藥中用到的有機污泥，在處理過程中必須嚴格遵守相關規(guī)定
and are closely monitored for compliance.
并進行嚴格的監(jiān)控，
Simply put, there is no current scientific evidence to show conclusively that
簡而言之，目前沒有科學證據(jù)能夠系統(tǒng)地表明
organic food is healthier than conventional food.
有機食品比傳統(tǒng)食品更加健康
While the French tomato study indicated higher vitamin C
盡管在法國的實驗中，用于測試的有機番茄中確實含有更多的
and carotinoid levels in a specific type of tomato tested,
維生素C和類胡蘿卜素，
there was no noted increase in antioxidant properties.
但它們并沒有使人體內抗氧化物的數(shù)量增加，
Unfortunately,there are few studies that have shown any benefits of nutritional quality in organic foods,
不幸的是很少有研究能夠表明，有機食品中的營養(yǎng)物質對人體有哪些好處，
and most of the tests showed only one type of vegetable in specific soils and under specific growing conditions.
大多數(shù)實驗只檢測了某種土壤環(huán)境下，在某種生長環(huán)境下的一種蔬菜
The question as to whether the consumption of organically grown vegetables
關于食用有機食品是否會比食用傳統(tǒng)食品會給人的身體
causes any greater microbiological risk to consumers than conventional vegetables remains unclear.
帶來更大的微生物層面的風險這個問題現(xiàn)在還不明了
While some studies show higher bacterial contamination in conventional versus organic crops,
一些研究顯示，傳統(tǒng)食品中的細菌污染更嚴重，
other studies indicate more bacterial contamination in organic versus conventional crops.
而另一些實驗則表明有機食品中的細菌污染更加嚴重
As we've seen, animal manure that hasn't been properly composted significantly increases E-coli levels,
正如我們所見，沒有經(jīng)過適當發(fā)酵的動物糞便會增加大腸桿菌的數(shù)量
and animal manure is a big factor in organic farming.
而動物糞便在有機農(nóng)業(yè)中又不可或缺
Another factor in food safety concerns the use of antibiotics in the production of animals for food.
食品安全中的另一個問題就是在肉類生產(chǎn)過程中用抗生素
While a University of Iowa study reported MRSA prevalence in one facility,
衣阿華大學的研究發(fā)現(xiàn)，一個農(nóng)場中的MRSA感染率極高，
researchers were unable to find a reason for the lack of MRSA at another facility.
而另一個農(nóng)場卻沒有，但他們卻無法找到其中的原因
In the Denmark study,
在丹麥的研究中，
banning the use of antibiotics in growth promotion resulted in increasing the need for therapeutic drug intervention
禁止將抗生素用來促進家畜的生長，使得藥物干涉的需求越來越高，
and an increase in human antibiotic resistance to food borne pathogens,
同時使得人類體內的眾多病原體產(chǎn)生了抗體
specifically salmonella and campylobacter.
尤其是沙門氏菌和彎曲菌屬，
Obviously, more research is needed to determine the benefits and shortfalls in the use of antibiotics in animal production.
顯而易見，要確定在家畜的生長過程中使用抗生素有哪些利弊，我們還需要更多的研究，
Now that you've seen the popular arguments and the scientific evidence, what do you think?
現(xiàn)在我們已經(jīng)看到了社會上流行的說法和科學提供給我們的證據(jù)，大家會怎么想呢?
When it comes to making the best decision for you and your family,
關于為自己和家庭選擇何種食品，
the decision on whether or not to buy organic foods is solely up to you.
是否選擇有機食品這個決定完全在于你自己，
Organic foods are usually more expensive and have less seasonal availability,
有機食品通常更貴，季節(jié)性也更加明顯
but may appeal to consumers who feel the increased cost is worth it.
但可能會讓一些消費者覺得物有所值，
Conventional foods have their own benefits.
而傳統(tǒng)食品也有它們自己的優(yōu)勢，
They are widely available year round.
它們一年四季皆可買到，
They are more budget friendly.
并且價格更加低廉
And some consumers trust the brand name associated with certain foods.
一些消費者對于某些品牌的食品具有特殊的信任，
Simply put, there is not enough scientific evidence to favor one type of production over another.
簡而言之，目前還沒有足夠的證據(jù)表明，兩種食品之間的優(yōu)劣
What's more important is that you continue to eat the recommended intake of fruits and vegetables
更重要的是，不論你選擇傳統(tǒng)食品還是有機食品，
whether your choice is conventional or organic.
你都應該每日食用一定量的蔬菜或水果
For optimal health and nutrition,
要吸收足夠的營養(yǎng)來保持身體健康
you should strive to consume two and a half cups to three cups of vegetables and two cups of fruit each day.
每天最好食用兩杯半到三杯蔬菜以及兩杯水果
