“This includes food produced from regenerative farming systems, food from Fairtrade farmers,Rainforest Alliance growers, and food that is eco-labelled for its carbon footprint and impact on the planet. There are some small nutritional differences in organic foods, but they are marginal and won’t play a significant difference in overall health. While there may be respected studies that find more nutrients in organic foods, a great many others have found insufficient evidence to recommend organic over non-organic for health or safety. A 2016 review of published research confirmed that organic milk has higher levels of omega 3 but lower levels of iodine. So consider, whether the benefits outweigh the risks in your particular circumstances.
The ‘clean 15’ is a similar list of the 15 conventionally grown fruits and vegetables which are thought to have the lowest level of pesticide residue. Organic products may have a slightly higher risk of contamination with pesticides or antibiotic-resistant bacteria . However, the research is mixed about this, other production factors are more likely to cause contamination and there isn’t good evidence that this contamination is harmful . The levels of pesticide used when growing non organic food are controlled by government and levels of pesticide on the surface of food can be reduced by thorough washing. Research shows that organic milk has 30-40% less iodine content than its conventional counterpart owing to different farming strategies. Interestingly, it seems that Vitamin C and other key nutritional components of food are known to be affected by factors such as handling and storage conditions.
Although overall they are safe, we are advised to wash our produce before we eat it to remove pesticide residues. Some research suggests that high exposure to pesticides in early life may harm cognitive development, but findings are mixed. Some organic products have been found to be a bit higher in phosphorus but lower in protein.
They have also stated that if half of the farms in the EU followed organic principles by 2030, Europe’s greenhouse gas emissions would be cut by over a quarter and much more carbon would be stored in the soil. The EU is also working with farmers to make it easier for them to convert to organic practices. This will hopefully ensure that organic produce becomes more widely available and affordable. Given the increasing awareness of the environmental impact of food, more and more people are paying close attention to where their food comes from, how it’s cultivated and how it makes its way onto our plates.
This wax is made up of chemical contaminants, so if you’re eating non-organic cucumbers, remove the skin. Changes in varieties – modern farming chooses varieties for high yield, not for nutritional value. Similarly, they choose varieties which are not prone to damage on supermarket shelves. Organic meat contains 47% more omega-3 fatty acids, and significantly lower concentrations of the undesirable saturated fatty acids. While the above are the most pesticide contaminated foods, the below aren’t – that is, they are known to not contain as many pesticides, and therefore can provide peace of mind for you knowing that you’re not consuming shedloads of the bad stuff.
These investigations all sought to find out whether organic food was in fact more nutritious. The researchers found that organic produce was much higher in polyphenols such as flavonoids, carotenoids and anthocyanins. Depending on the type of polyphenol that the researchers assessed, the organic produce contained 19-69% more. As the researchers concede, one of the inherent weaknesses of this study was that organic food production is a broad and complex topic that introduces a wide range of variables. The researchers did find that organic produce was less likely to be contaminated with pesticides. And any bacteria found in organically produced meat were less likely to be resistant to antibiotics.
As shown in this paper, what may be called an organic food system offers an instructive example of combining sustainable food production and consumption patterns within one system. However, actually defining an organic food system needs further research and development. Therefore, during the last decade, many studies and reviews were performed investigating how organic agriculture and food production as well as parts of the value chains contribute to sustainable food production. As a consequence, studies on consumer behavior as well as consumption patterns were also carried out.
Chris then set up his own market stall in the centre of Chester and asked volunteers to taste the organic and non-organic produce and rate which one they preferred. One potential issue here is the so-called ‘cocktail effect’ – the mixture of different pesticides. Pesticides are tested individually, says Percival, and the combination might “interact in unpredictable ways, it could have adverse health effects.” We just don’t know yet. The fact that several pesticides, once thought safe, have since been banned doesn’t inspire confidence. The organic movement was spearheaded in the first half of the 20th century, partly in response to the modernisation of agriculture. The UK lags behind many other countries in terms of government support for accessible organic food.

Dr Bravata added when discussing the research that, “if you look beyond health effects, there are plenty of other reasons to buy organic instead of conventional”. As a result, its findings may not be as reliable as those of a systematic review or meta-analysis focusing on a narrower issue, such as whether statins can prevent heart disease. She also runs the blog DieteticallySpeaking.com, as she is passionate about promoting evidence-based nutrition and fighting nutritional nonsense. Pregnant women, young women and vegans who drink organic milk and are already iodine-deficient should ensure adequate iodine intake from other sources.
