27、0)Is It Worth Eating an Organic Diet?Organic or Inorganic A. Sales of organic food have been rising steadily over the past decade, reaching almost $30 billion in 2011, or 4.2% of all U.S. food and beverage sales, according to the Organic Trade Association. Many of the consumers who purchase these pr

28、oducts say paying more for organic produce, milk and meat is a trade-off they are willing to make in order to avoid exposure to chemical pesticides and fertilizers and milk from cows given bovine growth hormone (牛生长激素). Some experts say common sense should tell us that food grown without the help of

29、 synthetic chemicals is probably safer and healthier to consume than food containing those substances, even in trace amounts. They believe Americans should try to substitute organic products for conventional ones whenever possible. B. However, other families, especially those whose food budgets may

30、be more limited wonder if organic food is really worth its hefty price tag. Other experts point out that there isn“t enough scientific evidence to say for sure that eating organic food leads to better health. As such, they say the most important dietary advice they can give Americans is to eat more

31、fresh fruit and vegetables and less processed food. C. Alex Leo, associate professor of environmental exposure biology at the Harvard School of Public Health, argues for eating more organic food. Janet H. Silverstein, a professor of endocrinology (内分泌学) at the University of Florida and a co-author o

32、f an American Association of Pediatrics (儿科学) study on the health benefits of an organic diet, takes the skeptic“s view. So far, researchers haven“t been able to provide them with a definitive answer. Short Exposure to Pesticide D. Is there definitive scientific proof that an organic diet is healthi

33、er? “Not yet,“ said Leo. Robust scientific studies comparing food grown organically and food grown conventionally don“t exist, thanks to a lack of funding for this kind of research. “The lack of definitive evidence combined with the higher price of organic food has given skeptics a golden opportunit

34、y to argue that organic isn“t worth the cost and effort,“ he added. E. While studies in recent years have delivered a decidedly mixed message about the healthfulness of organic food, those on both sides of the debate generally agree that organic produce typically contains fewer pesticides than conve

35、ntional produce, and that people may be able to reduce or eliminate agricultural chemicals from their bodies by adopting an organic diet. This was illustrated in a study published in the journal Environmental Health Perspectives in 2006. That study, which was led by Leo, showed that within five days

36、 of substituting mostly organic produce for conventional produce in children“s diets, pesticides disappeared from the children“s urine (尿液). Protective Effect F. Many say the pesticides found in our food are nothing to fear because the levels fall well below federal safety guidelines and thus aren“t

37、 dangerous. Similarly, they say the bovine growth hormone used to increase cows“ milk yield is perfectly safe. But federal guidelines don“t take into account what effect repeated exposure to low levels of chemicals might have on humans over time. And many pesticides were eventually banned or restric

38、ted by the federal government after years of use when they were discovered to be harmful to the environment or human health. G. Pesticides, in particular, are made to kill organisms, and the President“s Cancer Panel in 2010 made clear that it sees them as a threat, advising Americans to “reduce thei

39、r cancer risks by choosing, to the extent possible, food grown without pesticides or chemical fertilizers.“ H. Recent field studies showed that organic produce, such as strawberries, leafy vegetables and wheat, not only tastes better but contains much higher levels of phenolic acids (酚酸) than conven

40、tional produce. Phenolic acids can prevent cellular damage, and offer some protection against oxidative stress (氧化应激), inflammation and cancer. The Price Debate I. Yes, organic food typically costs more and can be harder to find than traditional food, but one could argue that the price of convention

41、al food is artificially low because of all the subsidies that organic farmers don“t get and that the government could do more to help organic farmers lower their costs. Nevertheless, when bought in-season, organic produce is often comparable in price to conventional produce. J. A good strategy for c

42、onsumers on limited budgets is to buy the organic versions of foods on the Environmental Working Group“s “Dirty Dozen“ list, as they typically contain the most pesticides. Or, consumers could focus on buying the organic versions of the foods they eat most. Knowing that we could reduce our exposure t

43、o pesticides and increase our exposure to antioxidants (抗氧化剂) by eating organic food, it makes great common sense to consume more of it. K. Organic food is more expensive than conventional offerings, which could make it cost-prohibitive for families on limited food budgets. Given the lack of data sh

44、owing that organic food leads to better health, it would be counterproductive to encourage people to adopt an organic diet if they end up buying less produce as a result. If families can afford to buy organic and still put a good amount of healthy food on the table, then the decision about whether t

45、o spend the extra money on organic produce, milk and meat should be based on a solid understanding of what we do and don“t know about the benefits. Pesticides and Safety L. It is difficult to compare the nutritional value of organic versus conventional food because the soil, climate, timing of harve

46、st, and storage conditions all affect the composition of produce. Still, published studies have found no significant differences in nutritional quality between organic and nonorganic produce or milk. Similarly, there is no evidence that giving bovine growth hormone (BGH) to cows changes the composit

47、ion of milk or affects human health. BGH is inactive in humans and degrades in the acidic environment of the stomach. As for pesticide exposure, the U.S. in 1996 established maximum permissible levels for pesticide residues in food to ensure food safety. Many studies have shown that pesticides level

48、s in conventional produce fall well below those guidelines. M. While it“s true that organic fruits and vegetables in general contain fewer traces of these chemicals, we can“t draw conclusions about what that means for health as there haven“t been any long-term studies comparing the relationship betw

49、een exposure to pesticides from organic versus nonorganic foods and adverse health outcomes. It may seem like “common sense“ to reduce exposure to these chemicals, but there are currently no good evidence-based studies to answer the question. N. While awaiting definitive studies, families on limited budgets who are concerned about pesticide exposure can refer to the Environmental Working Group“s list of the “Dirty Dozen,“ those foods with the highest pesticide residues, and the “Clean 15“, the food
