Is It Worth Buying Organic Food?
Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (商标). However, if you think paying a little more for organic food gets you a more nutritious and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren't necessarily more nutritious, and they're no less likely to suffer from disease-causing bacteria, either.
The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. "We did not find strong evidence that organic food is more nutritious or healthier," says Dr. Crystal Smith-Spangler from Stanford. "So consumers shouldn't assume that one type of food has a lower risk or is safer."
For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.
While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both
organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.
Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn't always translate into a more nutritious or healthier product. The U. S. Department of Agriculture (USDA) states that "whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste." Fresh food is at least as good as anything marketed as organic.
1.The new research questions whether organic food __________.
A. should replace traditional food

Organic foods are produced according to certain production standards, meaning they are grown without the use of conventional pesticides, or chemical fertilizers and that they were processed without food additives. Livestock are raised without the routine use of antibiotics(抗生素)or growth hormones. In most countries, organic produce must not be genetically modified. They may also be required to be produced using energy-saving technologies and packaged using recyclable materials when possible.
Early consumers interested in organic food would look for non-chemically treated, fresh or minimally processed food.
They mostly had to buy directly from growers: “Know your farmer, know your food” was the motto. Personal definitions of what constituted ( 组成)“organic” were developed through first-hand experience: by talking to farmers, seeing farm conditions, and farming activities. Historically, organic farms were relatively small family-run farms — which is why organic food was once only available in small stores or farmers’ markets.
However, since the early 1990s organic food has had growth rates of around 20% a year. As of April 2008, organic food accounts for 1 - 2% of food sales worldwide. Currently organic food production is legally regulated. Many countries require producers to obtain organic certification in order to market food as organic.
Several studies have attempted to examine and compare conventional and organic systems of farming. The general consensus(共同看法)is that, in the short term, organic farming is less damaging for the following reasons:
● Organic farms do not release synthetic pesticides (合成农药) into the environment — some of which have the potential to harm soil, water and local wildlife.
● Organic farms are better than conventional farms at keeping diverse ecosystems, i.e., populations of plants and insects, as well as animals.
● Organic farms are more energy efficient and produce less waste.
Another report published in March 2008 by The Organic Center claims that organic food is on average 25% more nutritious than conventional food.
However, many critics believe that the increased land needed to farm organic food could potentially destroy the rainforests and wipe out many ecosystems. And organic products cost 10 to 40% more than similar conventionally produced products. Processed organic foods in supermarkets are 65% more expensive.
1. Early consumers knew what food was “organic” by _______.
A. firsthand experience B. the “certified organic” label tag
C. its packaging D. examining its organic certification
2. We can infer that _______.
A. in America, organic food can only be bought in small stores or farmers’ markets
B. organic food is also available in large supermarkets at present
C. organic food is produced by large-scale farms
D. organic food is often beautifully packaged
3. According to the passage, organic food is considered as _______.
A. junk food B. delicious snacks C. green food D. conventional food
4. What is the main idea of the last paragraph?
A. The benefits of organic food. B. The cost of organic food.
C. The disadvantages of organic food. D. Organic food and conventional food.
5. Which of the following statements does NOT support the view that organic farming is more environment-friendly?
A. Organic food is generally thought to be more nutritious.
B. Organic farms are more energy efficient and produce less waste.
C. Organic farms are better than conventional farms at maintaining varieties of plants, insects and animals.
D. Organic farms do not release synthetic pesticides into the environment.
