Showing results for: Food type

Different foods will have different consequences for greenhouse gas emissions, other environmental impacts and for health. This category contains links to research which analyses particular food groups including meat, fruit and vegetables, carbohydrates and dairy products.

An ad used by Arla Foods to promote their organic milk has been banned as it used the "misleading" claim that its production is "good for the land".

This paper proposes a solution to the problems associated with the high inefficiencies and indirect detrimental environmental impacts caused by reactive nitrogen use in agriculture.The researchers suggest that land-based agriculture could be bypassed and that Haber Bosch derived nitrogen could be used directly for reactor based microbial protein production. The advantages of microbial protein production are summarised, as are the opportunities and technical challenges for large-scale production. The authors emphasise that, aside from the scientific innovation required, the main challenge to address is obtaining acceptability from regulators and consumers.

This report from The Eating Better Alliance looks at the role of business in leading the way to help people make healthy and sustainable choices, including shifting to more plant-based eating with less and better meat.

This paper compares stylised, hypothetical dietary scenarios to assess the potential for reducing agricultural land requirements. It suggests that a combination of smaller shifts in consumer diet behaviour – such as reducing beef consumption by replacing with chicken, introducing insects into mainstream diets and reducing consumer waste – could reduce agricultural land requirements.

A Global Meat News survey of top industry professionals analysing trading trends and impacts on the meat industry globally shows that most respondents (24%) stated that the pressure to limit meat consumption was the factor that hit the industry as a whole the hardest in 2016.

In this paper FCRN member Afton Halloran and colleagues Hanboonsong, Roos and Bruun present a life cycle assessment of insect farming, based on their research on cricket and broiler farms in north-eastern Thailand as well as a socio-economic impact analysis of this production.

In this editorial in the medical journal BMJ, professor of epidemiology John D. Potter discusses the mounting evidence that our current levels meat consumption harms human health and is equally bad for the planet.

A common hypothesis used to link declining human health to environmental outcomes predicts that illness will reduce human populations or harvest effort, thus benefitting the environment. When investigating the behaviour of fishers around Lake Victoria in Kenya, this research found little evidence that illness reduced fishing effort to indirectly benefit the environment. Instead, ill fishers shifted their fishing methods – using more illegal methods concentrated in inshore areas, that are less physically demanding but environmentally destructive.

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.

This paper models human and natural influences on the global capture of wild marine fish. The researchers show that wild fish harvest increases during the 20th century were most likely explained by improvements in fishing technology. Their simulated future projections, that assume ongoing technological progress and open access (i.e. no policy constraints), suggest a long-term decrease in harvest due to over-fishing.
