The next version of Dietary Guidelines for Americans, from the U.S. Department of Agriculture (USDA) and the Department of Health and Human Services (HHS) seem likely to include advice on sustainable diets. Preliminary conclusions from a subcommittee on food sustainability and safety indicate that the message of how the food is produced will be included in the final recommendations. For more on these subcommittee discussions read an article in Science here.          Read more a bout the dietary guidelines here. You can also find more information on our website about other dietary guidelines and food policy.

The Centre for Alternative Technology (CAT)  has launched a new report on sustainable diets - People, Plate and Planet, describing dietary choices that can reduce greenhouse gas emissions and pressures on land. The report considers nutrition, GHG emissions and land use and states that the most significant impact on these areas comes from what we eat, not where it is from or how much packaging there is around it.

Square Meal: why we need a new recipe for farming, wildlife, food and public health’ is a new report published by The Food Research Collaboration, the RSPB, Friends of the Earth, the National Trust, the Food Ethics Council, Sustain, the Wildlife Trusts, the Soil Association, Eating Better and Compassion in World Farming.

This study, undertaken by UK researchers from the University of Newcastle uses the extensive data set of 343 peer-reviewed publications in a meta-analysis to investigate ‘differences in composition between organic and non-organic crops/crop-based foods’. It suggests that there are ‘statistically significant’ differences between the production methods particularly with regard to a range of antioxidants.

The book ‘Challenging Consumption’, produced by the CONSENSUS research team, explores the topic of sustainable consumption. It includes discussions on future scenarios and innovations for sustainable food consumption practices. The book was launched in Dublin on 12th June 2014 by Dara Lynott, a Director of the Environmental Protection Agency who funds CONSENSUS research.

This study is one of the very few that examines the GHG impacts of a selection of real life ‘self selected’ diets as opposed to those that are modelled or hypothetical.  It looks specifically at the dietary patterns (based on a standard 2,000 kcal diet) of UK vegetarians, semi-vegetarians and non-vegetarians.  Approximately 55,500 subjects were chosen for the study, all part of the EPIC-Oxford cohort study.

This study published by the European Commission's Joint Research Centre in the journal Environmental Research Letters analyses the water footprint of agricultural production and consumption in Europe. It looks at the net virtual water import of 365 European river basins for the period between 1996-2005 based on two diet scenarios – a healthy diet based upon food-based dietary guidelines and a vegetarian diet.

Government leadership and substantial investment in research are needed to shift global consumption habits towards eating patterns that are both healthy and sustainable, say academics, industry and NGOs representatives in this report.
