abstract: This report was presented at the UK Organic Research 2002 Conference. Any attempt to answer the question ‘is organic food better for you?’ requires an assessment of the safety, nutritional content and biological value aspects of food quality. Previous reviews have been unable to reach definitive conclusions after failing to ensure only valid comparisons are considered. When methodologically flawed studies are screened out and a complete assessment of nutritional quality is made, collectively, the available evidence supports the hypothesis that organically produced food is superior in terms of safety, nutritional content and nutritional value to that produced non-organically. More research is needed provide to more data further investigating the trends seen in the existing evidence.
