Organic 'has no health benefits'

Food Standards Agency (FSA) публикува през юли резултатите от студия, показваща, че консумирането на огранична храна не носи здравословни облаги.

An independent review commissioned by the Food Standards Agency (FSA) shows that there are no important differences in the nutrition content, or any additional health benefits, of organic food when compared with conventionally produced food. The focus of the review was the nutritional content of foodstuffs.

Gill Fine, FSA Director of Consumer Choice and Dietary Health, said: ‘Ensuring people have accurate information is absolutely essential in allowing us all to make informed choices about the food we eat. This study does not mean that people should not eat organic food. What it shows is that there is little, if any, nutritional difference between organic and conventionally produced food and that there is no evidence of additional health benefits from eating organic food.

'The Agency supports consumer choice and is neither pro nor anti organic food. We recognise that there are many reasons why people choose to eat organic, such as animal welfare or environmental concerns. The Agency will continue to give consumers accurate information about their food based on the best available scientific evidence.’

The study, which took the form of a ‘systematic review of literature’, was carried out by the London School of Hygiene and Tropical Medicine (LSHTM). LSHTM’s team of researchers, led by Alan Dangour, reviewed all papers published over the past 50 years that related to the nutrient content and health differences between organic and conventional food. This systematic review is the most comprehensive study in this area that has been carried out to date.

The FSA commissioned this research as part of its commitment to giving consumers accurate information about their food, based on the most up-to-date science.

This research was split into two separate parts, one of which looked at differences in nutrient levels and their significance, while the other looked at the health benefits of eating organic food. A paper reporting the results of the review of nutritional differences has been peer-reviewed and published today by the American Journal of Clinical Nutrition.

Dr Dangour, of the LSHTM’s Nutrition and Public Health Intervention Research Unit, and the principal author of the paper, said: ‘A small number of differences in nutrient content were found to exist between organically and conventionally produced crops and livestock, but these are unlikely to be of any public health relevance. Our review indicates that there is currently no evidence to support the selection of organically over conventionally produced foods on the basis of nutritional superiority.’

Organic food is no healthier than ordinary food, a large independent review has concluded.

There is little difference in nutritional value and no evidence of any extra health benefits from eating organic produce, UK researchers found.

The Food Standards Agency, which commissioned the report, said the findings would help people make an "informed choice".

But the Soil Association criticised the study and called for better research.

Researchers from the London School of Hygiene and Tropical Medicine looked at all the evidence on nutrition and health benefits from the past 50 years.

Among the 55 of 162 studies that were included in the final analysis, there were a small number of differences in nutrition between organic and conventionally produced food but not large enough to be of any public health relevance, said study leader Dr Alan Dangour.

Overall the report, which is published in the American Journal of Clinical Nutrition, found no differences in most nutrients in organically or conventionally grown crops, including in vitamin C, calcium, and iron.

The same was true for studies looking at meat, dairy and eggs.

Differences that were detected, for example in levels of nitrogen and phosphorus, were most likely to be due to differences in fertilizer use and ripeness at harvest and are unlikely to provide any health benefit, the report concluded.

The review did not look at pesticides or the environmental impact of different farming practices.

Gill Fine, FSA director of consumer choice and dietary health, said: "Ensuring people have accurate information is absolutely essential in allowing us all to make informed choices about the food we eat.

"This study does not mean that people should not eat organic food.

"What it shows is that there is little, if any, nutritional difference between organic and conventionally produced food and that there is no evidence of additional health benefits from eating organic food."

She added that the FSA was neither pro- nor anti-organic food and recognised there were many reasons why people choose to eat organic, including animal welfare or environmental concerns.

Dr Dangour, said: "Our review indicates that there is currently no evidence to support the selection of organically over conventionally produced foods on the basis of nutritional superiority."

He added that better quality studies were needed.

Peter Melchett, policy director at the Soil Association said they were disappointed with the conclusions.

"The review rejected almost all of the existing studies of comparisons between organic and non-organic nutritional differences.

"Although the researchers say that the differences between organic and non-organic food are not 'important', due to the relatively few studies, they report in their analysis that there are higher levels of beneficial nutrients in organic compared to non-organic foods.

"Without large-scale, longitudinal research it is difficult to come to far-reaching clear conclusions on this, which was acknowledged by the authors of the FSA review.

"Also, there is not sufficient research on the long-term effects of pesticides on human health," he added.
