A 2009 FSA report into the health benefits of organic foods followed best practice at all stages, an independent review by the General Advisory Committee on Science has found.

The Soil Association and the Organic Trade Board had complained about the report, which said there was no scientific evidence that eating organic food delivered health benefits over and above non-organic fare. The Soil Association and the OTB said at the time that the scope and analysis of the study was too narrow and it did not take into account a wide enough range of sources.

According to the GACS review, the FSA report had followed good scientific practice it had published its study protocol online at an early stage and invited comments. The work had also undergone "extensive and rigorous peer review", the GACS said, both by external advisers and by a respected scientific journal.

But the GACS did make two recommendations for future improvements, saying the FSA should have a clear policy on how underpinning data would be released into the public domain, and give stakeholders advance warning if results were likely to be published at short notice.
