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.
A new report by Sustain, the alliance for better food and farming, calls for the UK Budget 2013 to implement a sugary drinks duty to fund a ‘Children’s Future Fund’ for spending on programmes to improve children’s health and future well-being.
A study published in the journal Perspectives on Psychological Science reviews the Database on Raising Intelligence to find interventions that increased children’s intelligence. One such intervention involved supplementing infants with long-chain polyunsaturated fatty acids, and the study concludes that this does indeed have a positive impact on children’s IQ.
The European Commission has released a report entitled: Prospects for Agricultural Markets and Income in the EU from 2012-2022. The report predicts that total meat production in the EU is expected to decline by 2% over the next two years, due in part to the ban on sow stalls. After the oncoming 2% decline, it may take up to 10 years for the EU meat sector to reach its 2011 production level of 45 million tones. The report also predicted that the EU would see its share of global meat exports decline over the next decade.
A new book entitled “Principles of Sustainable Aquaculture: Promoting Social, Economic and Environmental Resilience” by Stuart W. Bunting of the Centre for Environment and Society at the University of Essex serves as an advanced level textbook focusing on developing more sustainable aquaculture practices.
A study regarding the efficiency of beetle larvae (mealworms) as a potential protein source was published in the journal PLOS ONE by researchers at the University of Wageningen in Netherlands. The researchers compared the environmental impact of meat production on a mealworm farm to traditional animal farms using three parameters: land usage, energy needs, and greenhouse gas emissions. From the start of the process to the point that the meat left the farm, they found that mealworms scored better than the other foods. Per unit of edible protein produced, mealworm farms required less land and similar amounts of energy.
A lifecycle assessment study, carried out by PE International, measured the greenhouse gas emissions emitted from the production of a number of dairy products in Australia to identify the industry’s overall carbon footprint. An industry cross section of primary data has been analysed from 140 farms across Australia.
Researchers at the University of Gothenburg, Sweden, have published a study in the journal Global Change Biology claiming that rising levels of atmospheric carbon dioxide have a negative impact on the protein content of wheat grain and thus its nutritional quality.
Russian authorities are considering a proposal put forward by the National Union of Consumers’ Rights Protection, which would tax high-fat products, as well as the use of antibiotics in meat production. The tax rate proposed is 10-20% for meat and dairy products with high cholesterol content. Russian authorities have reacted favourably to the proposed initiative, but there is fear that immediate adoption of the initiative could push meat prices to unpredictable levels, driving some manufacturers out of business.
This interesting blog on the Planet Earth Online website reports on a study from the University of Salford which conducted blind tastings for a range of fish species. Only 15% of British tasters were able to identify cod – even though this is apparently our favourite fish, and we are generally very reluctant to try anything else.
An article in Insights, the magazine of the International Food Policy Research Institute (IFPRI), explores the complex issues of increasing livestock production and consumption. As consumption is flattening in the developed world, over the next several decades demand for meat will continue to increase in the developing world. The article also explores the need for raising livestock sustainably in order to mitigate negative impacts on human health and the environment.
The International Food Policy Research Institute (IFPRI) recently produced an infographic on the food security implications of meat consumption, including health and nutrition, biodiversity and climate risks, and impact on poverty.

This study is in keeping with a range of others that consider the effects, to health and GHG emissions of reducing consumption of red and processed meats.
The FAO has published its latest State of World Fisheries and Aquaculture report. It finds that 2010, people consumed about 128 million tonnes of fish. In the last five decades, world fish food supply has outpaced global population growth, and today fish provides more than 4.3 billion people with about 15 percent of their intake of animal protein. Estimates for 2010 point to fish consumption reaching another new high of 18.6 kg per person.
FCRN mailing list member Kurt Schmidinger has recently been awarded his thesis on the following subject: "Worldwide Alternatives to Animal Derived Foods – Overview and Evaluation Models", subtitle "Solutions to Global Problems caused by Livestock".
FCRN mailing list member Anna Flysjö has successfully defended her thesis. The thesis takes the form of a summary overview section and 6 papers (5 of them published journal papers). Details as follows:
The PhD project has focused on some of the most critical methodological aspects influencing GHG emission estimates of milk and dairy products and how the methodology can be improved. In addition, the CF for different types of dairy products has been analysed. Based on these results, mitigation options have been identified along the entire dairy value chain.
