The Organic Lie

This was shocking to me. A study has shown that organic food does not contain more nutrients than non-organic food. From CNN: Study: Organic food not more nutritional:

However, 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."

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.

Even still, in 2006 the UK's Manchester Business School assessed the environmental impacts of food production and consumption and concluded that there isn't a clear cut answer to whether the environmental impact is greater on a trolley full of organic food compared to a trolley full of non-organic food.

Not so, was the response from the Soil Association.

It countered 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."

While the jury might still be out about whether organic farming is, on the whole, better for the environment, there is little doubt that it's a booming industry which is starting to catch on in other parts of the world.

Shocking!
Even so, while it may not be better for you, it'll be better for the environment. So if you can afford it, go ahead.
