5£®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 £¨É̱꣩£®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 17studies that compared health outcomes between consumers of organic against traditional food
products£¬and 223studies 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-3fatty 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£®
