Background Intake of most foods show correlations with other foods implying that change in the intake of one food affects the intake of other foods. However, it is unclear whether such relationships are quantitatively meaningful and should be considered when a change in dietary intake is suggested. Methods We used data from European Prospective Investigation into Cancer and Nutrition-Potsdam and the previously published pairwise partial correlations between 49 food groups and calculated the impact of modifications in three correlated food groups that are relevant for public health, i.e. whole grain bread, white bread and processed meat, on intakes of other foods and total energy. Results Increase in the quantities of whole grain bread by 25% resulted in lowered white bread quantities both in men (7%) and women (8%). A 25% decrease in quantity of white bread resulted in increased quantities of whole grain bread (10-11%) and decreased (6%) in processed meat. Lowering intake of processed meat by 25% resulted in lower intakes of refined bread in both sexes. A simultaneous increase of whole grain bread and decrease in white bread and processed meat amplified the desirable benefit by increasing intake of whole grain bread by 12 g in men and 16 g in women. Simultaneous modification of all three food groups resulted in an overall decrease of 212 Kcal in men and 121 Kcal in women. Conclusions In conclusion, this study could show that the interdependencies between the intakes of foods affect not only the implicated food of an intended change but the whole diet including energy intake. Key messages Food networks has the potential to identify optimum changes required to achieve desired modification in dietary intake.

The environmental regulation of the upstream gas industry in Queensland is based on the principles of ecologically sustainable development. There is an increasing emphasis on meeting the expectations of the general community with respect to impact assessment, the environmental performance of the industry and the ability of government to provide effective regulation. In Australian States, regulation of the industry is generally characterised by a combination of industry self-regulation and government licensing and co-regulation policies.Environmental administration and regulation in Queensland, that is, impact assessment, planning and monitoring of performance, is undertaken by the Department of Mines and Energy, primarily through Regional Offices. Direction is provided principally by Department policy and the Environmental Protection Act.Case studies are presented which illustrate the impact assessment processes for three different types of gas development projects: gas field development in southwest Queensland; construction of a gas pipeline; and development of a coal seam methane project.The Queensland Government is currently developing an Environmental Protection Policy for the upstream petroleum industry (the EPP (Petroleum)). The process of developing the EPP has involved considerable community and stakeholder input to encourage acceptance of the Policy by all parties. The process has identified several key issues for industry including: the need for multiple land use; the incremental nature of petroleum development (including the gas industry); the need to strengthen the impact assessment process; the need for an integrated, single agency regulatory regime; the need for greater accountability of both industry and government; and the need for adequate resourcing of environmental regulation.A possible new regulatory regime for the industry in Queensland, based on the co-regulation model, may include a two-tier system of impact assessment and a combination of compliance for operations with Codes of Practice or a project specific Environmental Management Plan and licences for emissions and certain high impact activities.The administrative framework would be provided by the Petroleum Act which is currently undergoing a major review.

In this essay, I address the different approaches of the EU and the WTO to the trade and environment conflict and find out in how far the present environmental policy of the EU is compatible with the conditions of the WTO's Art XX GATT. Therefore, I first establish the current level of environmental protection in the EU by analysing the standard aimed for by the EU and its realization in legislation and jurisprudence. To show how environmental protection works in practice, I analyse selected case law and show how EU courts treat trade restrictions on environmental grounds enacted by Member States. Having evaluated the current standard of the EU, I proceed to compare the result with the WTO. I briefly explain institutional environmental developments within the GATT 1947, important environmental cases before the establishment of the WTO 1994 and textual changes in the new WTO Agreement. I then evaluate how Art XX GATT is dealt with in key case law and simultaneously compare this to the results of my analysis of similar EU cases. To conclude, I give a brief outlook on pending cases and a summary of the results of my study in both the EU and the WTO ambit. I point out some important differences in legal texts and case law and finally come to give a negative answer to my initial question.
