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.

When the population of the port town began to suffer from poisoning, the police came to find the cause of the poison. They thought someone was poisoning the people on purpose but no one knew how it was possible. Soon people took the position that the pork was poisoned. It was a popular food everyone ate and it could have possibly made everyone sick. Anyone who had possession of pork would throw it out. Even the poorest of the poor wouldn’t eat pork. Signs were posted on poles and letters were sent to everyone to warn people of the pork. Shortly afterwards, even policemen in high positions were also getting sick.
Soon it became political and popular. Politicians rushed to the town to talk about politics and promised how they would find the solution if they were elected. Everyone was so sick that they didn’t care about politics. Everyone was in a position where he or she didn’t know what to do anymore. They went to the post office to mail posts out asking for help. The poor town didn’t know how to deal with the situation.
One day, a well-known scientist from New York came to the town with a huge box containing many instruments and his possessions. He went to pools and the port and made measurements. He was quiet and polite. Then one day he made a speech at a newspaper meeting-room to announce his findings.
“I am sorry to say your water supply is so heavily polluted; it is poisoned. I know who has been poisoning you all for such a long time. It is you who have been poisoning yourselves with pollution. A great deal of rubbish has been thrown into the water day after day. No one here has taken good care of the environment.
