This paper explores industrial influence over industry-funded studies, using Coca-Cola as an example. It finds that, despite Coca-Cola developing a set of principles to guide transparency in the research it funds, the terms of funding it provides for some projects theoretically allow Coca-Cola to terminate studies early without reason and demand the recall of all documents from the study. However, no evidence was found of Coca-Cola having actually suppressed the publication of studies with unfavourable results.

Extreme climate events such as droughts and heat waves are better predictors of yield anomalies than indicators of climate averages in maize, rice and soybeans, according to this paper. Irrigation can mitigate the negative yield impacts of frequent warm days.

This paper, written by researchers on the University of Oxford’s LEAP project and co-authored by the FCRN’s Tara Garnett, explores what drives the intensification of dairy farming, and the consequences for the environment, animal welfare, socio-economic wellbeing and human health. The paper also considers three potential approaches to addressing these consequences: sustainable intensification, multifunctionality, and agroecology.

This paper calculates the environmental impacts (climate change, acidification, eutrophication, land use, and water use) caused by either making a meal by using a meal kit (which contains pre-portioned ingredients for cooking a meal) or by buying the ingredients from a grocery store.

One in five adults in England, Wales, and Northern Ireland experienced some level of food insecurity in 2016, according to this paper, with people who are younger, non-white, less educated, disabled, unemployed or low-income being more likely to experience food insecurity. Low-income adults had a 28% probability of being food-insecure in 2004, which by 2016 had risen to 46%.

The impacts of palm oil plantations on human wellbeing depend on context and are neither uniformly negative nor positive, finds this study of villages in Indonesia. Oil palm plantations are more likely to lead to improved basic, physical and financial well-being in villages with relatively low existing forest cover and where most people make a living by producing goods for market, compared to villages with higher forest cover and where most people have subsistence-based livelihoods.

This paper maps the potential for different subnational, national, or regional areas to reduce their agricultural dependence on imported phosphorus fertiliser by recycling manure or urban waste (including both human excreta and household and industrial wastes).

This paper reviews data from the UK Biobank study and finds that higher consumption of red meat and alcohol are associated with a higher risk of colorectal (bowel) cancer, while higher consumption of fibre from bread or breakfast cereals is associated with a lower risk.

This paper explores the possibility of producing food by growing insect cells in the laboratory using cell culture techniques. It suggests that it may be easier to overcome certain technical challenges to cell culture by using insect cells rather than (say) beef, pork or chicken cells.

Decoupling of carbon emissions from economic growth is unlikely to happen quickly enough to meet the Paris climate targets of limiting warming to 1.5°C or 2°C, according to this paper. Furthermore, both historical trends and model-based projections suggest there is no evidence that resource use and economic growth can be absolutely decoupled at the global scale in the context of continued economic growth.

An open letter co-signed by over 600 European scientists and two Brazilian Indigenous organisations (which together represent 300 Brazilian Indigenous groups) calls for the European Union to make its trade negotiations with Brazil conditional on respecting Indigenous rights, protecting forests and defining strict social and environmental criteria for traded commodities such as iron and beef.

This paper quantifies the resource use implications of replacing fishmeal with plant-based ingredients in the feed used to farm shrimp. It finds that increasing the proportion of plant-based ingredients in shrimp feed could reduce pressure on marine resources, at the cost of increased use of freshwater, land and fertiliser.

This paper by FCRN member Claire Pulker of Curtin University analyses the presence and quality of supermarket corporate social responsibility (CSR) policies related to all attributes of public health nutrition, including sustainability. The paper audited Australian supermarket own brand foods to establish the extent to which CSR policies are translated into practice.

FCRN members Verena Seufert and Adrian Müller have contributed to this commentary, which outlines a set of policy measures for changing agricultural practices to be in line with the Sustainable Development Goals. The proposed policy measures include supporting organic agriculture.

This paper evaluates the impact of diet on risk factors for heart disease. It finds that replacing red meat with “high-quality” plant protein sources (such as legumes, soy or nuts), but not with fish or “low-quality” carbohydrates (such as refined grains and simple sugars), results in improvements in total and low-density lipoprotein cholesterol.

This paper traces mass, energy flows and emissions in the beef, poultry and pork supply chains in Germany (including all emissions from the animal production stages, and emissions from energy use at subsequent stages). It outlines the potential of different strategies to reduce consumption-based emissions. It finds that the greatest emissions reductions could come from dietary change, i.e. replacing some meat consumption with consumption of soybeans and nuts, or replacing some meat consumption with offal consumption.

This paper reviews studies where changes in both productivity and species richness have been tracked at the same location, following changes in the intensity of land use. On average, intensifying land use leads to a 20% gain in output and a 9% decrease in species richness, but there is considerable variation between different contexts.
