Introduction
Organic produce paints an appealing picture: better-quality fruit and vegetables, fewer pesticides, higher animal welfare standards and potentially better health. But this comes at an extra cost. So, what are you actually getting when you pay more for organic food, and is it really better for your health?
What does organic mean?
Organic food is produced according to specific farming standards that restrict the use of synthetic pesticides and artificial fertilisers and prohibit genetically modified ingredients. Instead, organic farming uses methods such as crop rotation, legumes such as clover to naturally enrich the soil, and manure to maintain soil fertility.
Organic standards also extend beyond fruit and vegetables. Animals raised under organic standards are subject to specific welfare requirements and routine preventative use of antibiotics is prohibited. Organic farming also aims to reduce its environmental impact through practices designed to protect soil health and biodiversity.
Organic products must be certified to be labelled as organic. For processed foods, at least 95% of the agricultural ingredients must be organic for the product as a whole to be labelled organic, with restrictions on which non-organic ingredients can make up the remainder.

Does organic fruit and veg have more nutrients?
Not necessarily. A systematic review combining 147 studies across 68 different foods compared the nutritional content of organic and conventionally produced food. Around 70% of comparisons either found no significant difference or produced inconsistent results.
Some organic foods contained higher concentrations of certain nutrients and antioxidant compounds. However, these differences were not consistent enough to conclude that organic food is nutritionally superior overall. Importantly, finding a higher concentration of a particular antioxidant or nutrient in a food does not necessarily mean that eating it will lead to better health.
Are chemical pesticides harmful?
Pesticides can be harmful at sufficiently high doses, and prolonged or high levels of exposure — particularly among agricultural workers — have been associated with a range of adverse health effects. However, this level of exposure is very different from the small amounts of pesticide residue that may remain on the fruit and vegetables we eat.
In the UK, maximum residue levels are set for pesticides in food and are generally well below levels considered a risk to health. Food is routinely monitored for pesticide residues, and when residues are detected, potential exposure to consumers can be assessed.
Organic fruit and vegetables generally contain fewer synthetic pesticide residues, so choosing organic can reduce your exposure. However, lower pesticide exposure does not necessarily translate into a measurable improvement in health. Current evidence has not established that the levels of pesticide residues typically encountered from eating conventionally grown fruit and vegetables cause harm.

Is organic food better for your health?
Another systematic review looked specifically at studies comparing health outcomes in people eating organic and conventionally produced fruit and vegetables. The studies investigated a range of outcomes including metabolic health, cardiovascular risk, obesity and cancer.
Six of the 12 studies found a significant association with at least one health outcome, including a lower risk of some cancers, particularly non-Hodgkin lymphoma, and a lower prevalence of obesity. However, this does not necessarily mean that eating organic food caused these differences.
One of the biggest problems with this research is that people who regularly buy organic food tend to behave differently from those who do not. They may be more health-conscious, have healthier overall diets or differ in other lifestyle and socioeconomic factors. Researchers can statistically adjust for factors such as smoking, exercise and diet, but it is difficult to eliminate these differences completely.
The studies also varied considerably in their design, populations, duration and outcomes measured. Overall, the evidence is therefore not strong enough to conclude that eating organic fruit and vegetables leads to better health than eating conventionally grown produce.
