The UNSCN Discussion Paper  “By 2030, end all forms of malnutrition and leave no one behind” aims to show the centrality of nutrition in the current sustainable development agenda.

This policy brief, produced by the PBL – the Netherlands environmental assessment agency, investigates the integrated approach that would be needed to making the food chain more circular. In a circular food chain, raw materials are used in a way that adds the most value to the economy and causes the least harm to the environment.

This comment article in The Lancet Planetary Health emphasises that food systems research, addressing sustainability and human health, needs to combine three factors equally to inform comprehensive improvement strategies. 

This research links the self-reported Food Frequency Questionnaire (FFQ) data of Swedish participants, to Life Cycle Assessment (LCA) data of carbon footprint for food products. The results of this study indicate that a self-selected diet low in diet related greenhouse gas emissions (GHGE) provides comparable intake of nutrients as a diet high in GHGE, and adheres to dietary guidelines for most nutrients.

This book is based on the papers that were presented and discussed at a workshop with the group “System Innovation towards Sustainable Agriculture” (SISA), an initiative by researchers from ‘Wageningen University & Research’ in the Netherlands (WUR) and the ‘Institut National de la Recherche Agronomique’ in France (INRA). 

Based on a case study from Oakland California, a new report by Friends of the Earth US finds that schools can make lunches healthier and more climate-friendly while also saving money— by reformulating menus so that they are more plant centred, and contain less (and better) meat and fewer dairy products.

The report Redefining Protein: Adjusting Diets to Protect Public Health and Conserve Resources distils current research looking at the social and environmental impacts of producing high-protein foods other than meat (legumes: pulses and soy, nuts and seeds, eggs and dairy). It aims to provide hospitals with key information to design healthier meals. 

This report, by the US based NRDC (The Natural Resources Defense Council) finds that the per capita diet related carbon footprint of the average US citizen decreased by 10% between 2005 and 2014, driven by a 19% decrease in beef consumption. 

In this letter to the editor in Nature, the authors challenge simplified dietary strategies used in lifecycle assessment (LCA) based studies. Citing a paper that presents the LCA of three dietary scenarios for a basket of food products (representative of EU consumption) they argue that “it is irresponsible to present environmentally motivated dietary strategies... that conflict with longstanding public health nutrition objectives.”.
