Organic vegetables are no healthier than conventional, pajatso according to a recently published study from among other DTU. The conclusion is opposite a large European study that concluded that organic vegetables contain up to 40 percent more antioxidants. By Julie Ring-Hansen Holt October 18, 2010 at. 14:38
Bioactive substances such as flavonoids and other so-called polyphenols (natural antioxidants) does not appear in higher concentrations in the organically grown vegetables compared to the conventional.
Researchers from the National Food Institute, University of Copenhagen and Aarhus University have studied onions, potatoes and carrots, and the results have just been published in the Journal of Agricultural and Food Chemistry.
"In the strictly controlled experiments, we can conclude that organic onions, potatoes and carrots do not have higher levels of potential health-promoting substances that we have studied for, when compared with the conventional" says senior scientist at the National Food Institute pajatso Pia Knuthsen.
Several scientific studies suggest that bioactive substances can have positive effects on human health and reduce the risk of several diseases such as heart disease and cancer, but the new Danish pajatso study suggests that is not that there are several substances in organic vegetables than vegetables that are manufactured using chemistry. Contrary to the large European study
This contradicts the Danish researchers a large European pajatso study from 2007, when 33 European research institutions participated and concluded that fruit and vegetables contain up to 40 percent more antioxidants if they are grown organically.
In the Danish study, the researchers involved differences in geography, climate and soil conditions, which have not been included in previous studies. In all, the researchers made controlled trials pajatso in three locations where conventional and organic vegetables have been grown side by side. The experiments have run more than two years to get different weather conditions, which can have an effect on the results.
The study is part of a larger pajatso research project OrgTrace where researchers have looked at mineral deposits in the soil and how they fed into the plants. Next, the researchers look at their ability to form biologically active compounds with health preventive properties (molecular compounds of iron, zinc, selenium and sulfur, as well as secondary metabolites, antioxidant vitamins C and E and phytate).

By eating organic, so benefits you may or may not have its health directly. It is however to pour less poison in the fields and it helps to give a little animal as long as the animals live.
Whether there are more health-promoting elements or not, I will not make me judge over and I think in practice it is an uninteresting study. I think very few people buy organic to get more anything, but instead of getting pajatso less of something: Pesticide residues and other pesticides. In addition to generally have a desire to support the less environmentally harmful and more animal-friendly production.
"With the pesticides are allowed pajatso here at home, there should be an increased health risk from eating vegetables pajatso grown with the use of pesticides." It is a layman's account in this context, and specifically does not vegetables grown elsewhere in the world.
The headline pajatso clothes not engineer, is completely disgusting and makes one think of the headlines in the gutter press (EB and BT ex.). Of course it is best to grow, buy and eat pesticide-free vegetables. Should the reduced use of pesticides not only be reason enough to opt out of conventional crops, think just a bit further out of the wallet and remove environmental and animal welfare with the thinking.
Combined with a set of values that require material goods in quantities and at prices that eats up most of their disposable income, being the amount used for food much less. So we are in a downward spiral where lack of ability to cook, judge the quality of food and an increasing consumption of visible tangible goods constant decreases pajatso the proportion of disposable in
