Showing results for: Food consumption
This randomized controlled study looked at how obese Norwegian men were affected by a diet very high in the intake of total and saturated fat, as compared to one high in carbohydrates, while controlling for intake of energy, protein, and polyunsaturated fats and food types.
Twenty-four cross-party European parliament members, together with HSI’s Planting Fresh Ideas, wrote a letter to the European Commission President, First Vice President, and Commissioners, with policy recommendations for reducing EU consumption of animal-based foods.

This systematic review confirms earlier findings that a number of well-categorised sustainable dietary patterns are also good for health outcomes. There was consistent evidence to suggest that diets higher in plant-based foods such as vegetables, fruits, legumes, seeds, nuts, and whole grains and lower in animal-based foods (especially red meat), are both healthier and associated with a lower impact on the environment.
This paper by FCRN member Lukasz Aleksandrowicz and colleagues consolidates current evidence on the environmental impacts of dietary change, finding environmental benefits are possible from shifting typical Western diets to a variety of alternative dietary patterns. The results also highlight that there is still complexity in defining environmentally sustainable diets, though moderate reductions in meat consumption (particularly ruminant meat) replaced by plant-based foods, seem to reliably reduce greenhouse gas (GHG) emissions, land use, and water use, as well as improve health.
The Eating Better Alliance has launched a new campaign about eating less meat. The alliance have worked to create a new way of talking about eating less meat, through fun and positive messages and a set of adverts to inspire a new generation of men to be more daring with their food and give vegetarian options a chance.
Researchers at CGIAR/CCAFS have written a report about different demand side measures aimed at changing food consumption so as to reduce GHG emissions. In particular, they placed their analysis in the context of the Paris climate agreement which aims to limit the increase of global temperatures due to anthropogenic climate change to below 2ºC.
At a time when interest in the sustainability of food is increasing, the need for well-defined, interdisciplinary metrics of the sustainability of diets is evident. In this study, a group of researchers from Michigan performed a systematic literature review of empirical research studies on sustainable diets to identify the components of sustainability that were measured and the methods applied to do so.
In a new report, entitled ‘Fiscal policies for diet and the prevention of noncommunicable diseases’, the World Health Organisation (WHO) advocates subsidies and taxes on healthy and unhealthy foods respectively. One of the report’s major conclusions was
This study estimates the environmental impacts of what it terms discretionary foods - foods and drinks that do not provide nutrients that the body particularly needs. It finds that these foods account for 33-39% of food-related footprints in Australia.
This study evaluates the attainability of sustainable targets for better integrating food security and environmental impacts. Many studies have looked at how much food production could increase given a plausible mitigation solution, for example if food waste was halved from 24% to 12% then an additional 1 billion people could be fed. These studies, however, lack a temporal component that this study attempts to include, which enables evaluation of whether these advances can keep pace with projected increases in human demand.
In this modelling study, the authors examine potential trade-offs between sufficient food provisioning in the future and sustaining biodiversity. On the one hand they find that cropland expansion increases food security, particularly in areas which are currently struggling with access to safe and nutritious food.
Psychological research has shown that people often don’t make decisions on a rational basis, but rather do so heuristically - based on rules of thumb - that can systematically bias choices. This has important implications when it comes to promoting the sustainable consumption of food.
This month’s issue of Discover Society is entirely dedicated to the topic of food and eating. Tara Garnett has contributed with an article on sustainable healthy eating patterns.
In the past few years there has been much interest in consumption behaviours and how these can be influenced for the better of the environment. A huge obstacle faced is that, compared to women, men are much less likely to be eco-friendly in their attitudes, choices and behaviours.
This study explores how fear of climate change affects affluent Swedish individuals in their intentions to reduce or alter meat consumption. Noting that fear appeals form the dominant communications approach used in raising awareness about environmental issues and motivating behavioural change, the authors set out to explore the processes through which such appeals may or may not motivate consumers to change.
