Conjugated linoleic acid isomer concentrations in milk from high- and low-input management dairy systems Organic Eprints
Butler, Gillian; Collomb, Marius; Rehberger, Brita; Sanderson, Roy; Eyre, Mick D.; Leifert, Carlo.
BACKGROUND: Different conjugated linoleic acid (CLA) isomers are known to have contrasting physiology or health effects and there is growing evidence that the profile of natural isomers in milk is influenced by the production system. This survey is the first to compare feeding regimes and concentrations of 14 CLA isomers inmilk from three production systems in the UK. RESULTS: Total CLA and seven isomers (including C18 : 2 c9t11 which comprised >80% of total) were significantly higher in milk from both organically certified and non certified low input (LI) systems compared with milk from conventional high input farms. Sampling date also affected concentrations of total CLA and nine isomers; being lowest in March and highest in August. Seasonal...

Composition differences between organic and conventional meat: a systematic literature review and meta-analysis Organic Eprints
Srednicka-Tober, Dominika; Baranski, Marcin; Seal, Chris; Sanderson, Roy; Benbrook, Charles; Steinshamn, Håvard; Gromadzka-Ostrowska, Joanna; Rembialkowska, Ewa; Skwarło-Sonta, Krystyna; Eyre, Mick; Cozzi, Giulio; Krogh Larsen, Mette; Jordon, Teresa; Niggli, Urs; Sakowski, Tomasz; Calder, Philip C.; Burdge, Graham C.; Sotiraki, Smaragda; Stefanakis, Alexandros; Yolcu, Halil; Stergiadis, Sokratis; Chatzidimitriou, Eleni; Butler, Gillian; Stewart, Gavin; Leifert, Carlo.
Demand for organic meat is partially driven by consumer perceptions that organic foods are more nutritious than non-organic foods. However, there have been no systematic reviews comparing specifically the nutrient content of organic and conventionally produced meat. In this study, we report results of a meta-analysis based on sixty-seven published studies comparing the composition of organic and non-organic meat products. For many nutritionally relevant compounds (e.g. minerals, antioxidants and most individual fatty acids (FA)), the evidence base was too weak for meaningful meta-analyses. However, significant differences in FA profiles were detected when data from all livestock species were pooled. Concentrations of SFA and MUFA were similar or slightly...

Higher antioxidant and lower cadmium concentrations and lower incidence of pesticide residues in organically grown crops: a systematic literature review and meta-analyses Organic Eprints
Baranski, Marcin; Srednicka-Tober, Dominika; Volakakis, Nikolaos; Seal, Chris; Sanderson, Roy; Stewart, Gavin B.; Benbrook, Charles; Biavati, Bruno; Markellou, Emilia; Giotis, Charilaos; Gromadzka-Ostrowska, Joanna; Rembiałkowska, Eva; Skwarło-Sonta, Krystyna; Tahvonen, Raija; Janovska, Dagmar; Niggli, Urs; Nicot, Philippe; Leifert, Carlo.
Demand for organic foods is partially driven by consumers' perceptions that they are more nutritious. However, scientific opinion is divided on whether there are significant nutritional differences between organic and non-organic foods, and two recent reviews have concluded that there are no differences. In the present study, we carried out meta-analyses based on 343 peer-reviewed publications that indicate statistically significant and meaningful differences in composition between organic and non-organic crops/crop-based foods. Most importantly, the concentrations of a range of antioxidants such as polyphenolics were found to be substantially higher in organic crops/crop-based foods, with those of phenolic acids, flavanones, stilbenes, flavones, flavonols...

Fatty acid and fat-soluble antioxidant concentrations in milk from high- and low-input conventional and organic systems: seasonal variation Organic Eprints
Butler, Gillian; Nielsen, Jacob H.; Slots, Tina; Seal, Chris; Eyre, Mick D.; Sanderson, Roy; Leifert, Carlo.
BACKGROUND: Previous studies showed differences in fatty acid (FA) and antioxidant profiles between organic and conventional milk. However, they did not (a) investigate seasonal differences, (b) include non-organic, lowinput systems or (c) compare individual carotenoids, stereoisomers of α-tocopherol or isomers of conjugated linoleic acid. This survey-based study compares milk from three production systems: (i) high-input, conventional (10 farms); (ii) low-input, organic (10 farms); and (iii) low-input non-organic (5 farms). Samples were taken during the outdoor grazing (78 samples) and indoor periods (31 samples). RESULTS: During the outdoor grazing period, on average, milk from the low-input systems had lower saturated FAs, but higher mono- and...
