I do not know when, weekend suburbs "farmhouse," one advocate leisure Petty became white-collar workers. Fruits and vegetables hand-picked or hand-picked to go through a simple cooking chicken after the end of the table, regardless of color, smell or taste than the company seems to be winning a lot of takeout. For those workers and businesses have no time to travel is also very considerate: in some large supermarkets, these natural products are known as the name for people to buy organic food.
The growth process does not use non-natural chemical itself is not genetically modified, process does not use chemical additives, organic food seems to have become synonymous with nutrition and natural, even more expensive than conventional food a lot, but still You can not stop enthusiasts in droves.
But naturally go natural, organic food really more nutritious than conventional foods? 2012 published in the authoritative medical journal "Annals of Internal Medicine" (Annals of Internal Medicine ) on the paper studied the problem. In the study, 12 researchers search for 1966 in seven academic databases - 2011 published comparison between organic food and conventional food nearly 6,000 papers, and ultimately chose the most relevant 237 as the object of analysis.
Results of the analysis seems to subvert the people's traditional impression. And compared to conventional fruits and vegetables, organic fruits and vegetables in the vitamin C (ascorbic acid), vitamin E (- tocopherol) and vitamin A (- carotene) content did not change significantly. In addition to vitamins, protein, dietary fiber and other major nutrients in fruits and vegetables are almost the same between the two. All 14 kinds of nutrients tested, in the organic fruits and vegetables were significantly higher than in the conventional content of fruits and vegetables in only two: phosphorus and phenols (such as capsaicin, etc.). The researchers believe that because the relationship between the number of samples, organic fruits and vegetables in the content of these two substances than conventional fruits and vegetables if you want to really open to question. Dairy products, meat, organic milk and chicken in -3 fatty acids to come later, but octadecenoic acid (a kind of trans-fatty acids) content will increase.
Although the content of nutrients only from the point of view as much as conventional food and organic food, organic food but not without people to commend them. The researchers found that organic food is less polluting. In 3041 different organic food samples, only 7% of the sample detected pesticide residues, whereas the conventional food this figure is as high as 38% (106 755 samples). In addition, although the surface of E. coli contamination rate is almost the same two foods, bacteria on food routine easier resistant to antibiotics (30% higher than the organic food).
Organic foods to be more healthy than conventional food, but not necessarily more nutritious? The researchers do not doubt the credibility of the conclusions in the statistical sense, but is full of cautious interpretation. Since the study is based on analysis of the different papers, such as pesticides and therefore the means of detection, plant growth environment and so have not been unified, to the credibility of the conclusions brought some variables. But generally, if you choose organic food in order to get more nutrition, then perhaps use the same money to buy more cost-effective to other conventional food and if you choose organic food in order to reduce food contamination that may remain on, or you think certain foods taste better, then perhaps organic food is indeed a good choice.
