Organic food not more nutritional

One possible spanner in the works for the organic sector could be the results of a new study by the University of Copenhagen which revealed that organic foods contained no more nutrients than non-organic foods grown with the use of pesticides.

Researchers studied five different crops -- carrots, kale, mature peas, apples and potatoes -- which were cultivated both organically (without pesticides) and conventionally (with the use of pesticides) and found that there was no higher level of trace elements in the food grown organically.

Study leader Dr Susanne Bügel said: "No systematic differences between cultivation systems representing organic and conventional production methods were found across the five crops so the study does not support the belief that organically grown foodstuffs generally contain more major and trace elements than conventionally grown foodstuffs."

It should be noted that the study does not make conclusions about the comparative levels of pesticides or chemicals in conventionally and organically grown food or the health effects of consuming such chemicals.

So if organic foods aren't necessarily more nutritional, are they better for the environment?

According to the Intergovernmental Panel on Climate Change, traditional agriculture accounts for around 11 percent of global greenhouse gas emissions each year, and the nitrous oxide found in fertilizers contributes most to these emissions.

The Soil Association said that: "Overall, organic farming is better for tackling climate change than industrial agricultural methods. As well as lower average energy use, organic farming also avoids the very large nitrous oxide emissions from fertilizer manufacture."

"Additionally, organic farming builds up soil carbon, removing it from the atmosphere. Organic farming also supports more local food marketing, reducing food miles."

Bonnie - aside from the fact that studies have shown organic to be more nutrient-dense than conventional, it is amazing that the study would not take into account the negative effects of pesticides in conventional produce. That alone makes organic a better choice regardless of nutrient content. See recent postings in our blog. How do you feel about organic versus conventional? Put in a comment below.

I am an advocate for organic foods and produce mainly because I believe we need to reduce the amount of pesticides we consume from our food supply. I just wrote a post about it on my own blog today if you are interested.

Thanks
