The Global Food Security (GFS) programme invites expressions of interest from post-doctoral researchers to take part in a Policy Lab on the determinants of food choice (for example biological, social, environmental, physical and economic) and the combination of interventions across these that will lead to healthier and more sustainable diets. Policy Labs bring together early career researchers from different disciplines to scope a policy-relevant issue, with teams forming at the workshop and then competing to write a synthesis report for the GFS programme. The winning team at the workshop will receive a £5,000 Policy Lab award to write a policy-facing report.
We seek applicants interested in interdisciplinary and systems approaches to a policy-relevant issue, who are looking for an opportunity to produce an evidence-based report that will be widely read by policymakers. The 3-day workshop will take place on the 19-21 March 2018 in London, and applicants must be available to attend on these days.
Researchers must meet the eligibility criteria to participate in the Policy Lab workshop. Researchers working in any relevant discipline can apply (including for example the environmental, biological, engineering and social sciences).
The major question that the Policy Lab aims to address is: what are the determinants of food choice and what combination of interventions across these would have the most impact in encouraging healthier and more sustainable diets.
The world faces a major challenge, as obesity levels continue to rise globally. The World Health Organisation estimates that in 2016, approximately 1.9 billion people in the world were overweight, of which at least 650 million were obese (ref 1). The overall cost of obesity to wider society in the UK has been estimated to be £27 billion, with the NHS spending an estimated £6.1 billion on overweight and obesity-related ill health in 2014/2015 (ref 2). The UK-wide NHS costs attributed to overweight and obesity are projected to reach £9.7 billion by 2050, with wider costs to society estimated to reach £49.9 billion a year. It is widely acknowledged that changes in the environment and organisation behaviour (ref 3), as well as changes in group, family and individual behaviour, is necessary in order to mitigate the effects of obesity, both on the health of individuals, and to reduce the burden to the global economy of obesity and non-communicable diseases (NCDs).
We also need to consider the environmental impacts associated with food production, with inflated demand caused by overconsumption creating additional burden on planetary resources and adding to greenhouse gas emissions – the agri-food system now responsible for about 30% of total global anthropogenic emissions (ref 4). The global overconsumption of protein is of particular concern, average per capita consumption 36% higher than recommended, with animal-based sources producing a disproportionate amount of greenhouse gas (ref 5). It has been estimated that if the average UK diet was moderated to align with WHO nutritional recommendations, national greenhouse gas emissions would decrease by 17% (ref 6).
Food-related emission reductions of this kind are necessary if we are to meet Paris climate change targets by 2050.
Though food consumption is primarily required to meet our physiological needs for nutrients and energy, the wider influences guiding our diets are actually highly complex, and encompass a range of social, cultural, psychological, economic and environmental factors working alongside biological cues to control our consumption patterns.
- Biological factors, such as the need for energy and nutrients to allow our bodies to grow and function. Appetite guides the amount we consume via a physiological system linking the brain and gut (ref 7); hormones released from both the gut and the body’s fat deposits indicating available energy levels to the brain, which in response triggers the feeling of either hunger or satiety. Microorganisms living inside the gut – known as the gut microbiome – are also thought to communicate via this gut-brain axis, stimulating consumption of foods that promote their own growth (ref 8).
- Economic access to food is affected by food price and individual disposable income, dictating the amount, type and quality of food available to different people. Relative affordability of foods can be measured by the share of household budget spent, the average household in the UK allocating 11.1% of their disposable income to food (ref 9).
- Physical access to food in terms of locality to and ability to reach different types of food shops and restaurants offering different selections of foods. For example, high exposure to fast food outlets has been linked to higher consumption of takeaway food and greater risk of obesity (ref 10). Food deserts can be described as areas with poor access to affordable healthy food, and are often considered responsible for obstructing healthy diets and propagating health inequalities (ref 11).
- Food preferences and habits, affected by tastes, upbringing, culture, religion and personal beliefs about certain types of foods. While such preferences operate at the individual level, they are learned through exposure to external determinants; for example, the food habits we learn from our families in early life have been shown to last into adulthood (ref 12).
- Modern social and cultural norms have resulted in more irregular working hours and fewer dedicated homemakers, encouraging wider consumption of convenience foods and higher incidence of eating meals and snacks outside the home.
- Food information and education, whether from governments, schools, or food businesses, is now readily available through a variety of sources, providing a spectrum of information from broad dietary advice down to specific nutritional content of foods. However, over 50% of UK consumers report finding such nutritional information hard to understand (ref 13), while some studies show that nutritional knowledge does not necessarily translate into behaviour (ref 14), suggesting that food and nutrition education alone is inadequate to help consumers make healthy dietary choices.
- Food advertising reaches us through a variety of media, providing significant promotion for branded products, shops and restaurants. Statistics from the Department of Health show that the commercial sector spent £838 million on promotion of confectionery, snacks, fast food and sugary drinks in 2007 (ref 15); this kind of advertising has been linked to increased consumption of foods high in fat, salt and sugar, especially in children (ref 16).
- Globalisation changes the domestic availability and price of certain foods, influencing consumption patterns. For example: greater foreign investment in food business and infrastructure can increase local food production and availability; the global spread of food media can familiarise foreign cuisines and influence preferences; and liberalised trade offers wider import options, allowing countries to import foods more cheaply as well as import novel foods.
This Policy Lab aims to further understand what drives food choices, the trade-offs and unintended consequences associated with a shift towards healthier and more sustainable diets, and the combination of interventions that might have the biggest impact.
In order to be eligible, researchers should:
- be currently employed as a post-doctoral researcher at a UK Higher Education Institute, Research Institute, or Independent Research Organisation that is eligible to receive grant funding from the Research Councils. Post-doctoral researchers based outside of the UK will not be eligible.
- have completed their PhD within the last five years. Applicants are therefore eligible if they have completed their PhD after 1 January 2013.
Applicants will also be expected to demonstrate evidence of skills relating to the person specification, which is outlined below. GFS will assess candidates based on this whilst ensuring a spread of disciplines at the Policy Lab.
In accordance with The Concordat (ref 17), researchers are encouraged to undertake Continuing Professional Development (CPD) activities, which can be beneficial for both the researcher and institution. GFS would like applicants to consider whether they would be able to designate adequate time for writing the report as a part of a team. We therefore encourage applicants to seek permission from their supervisor to participate in the workshop, and to develop the subsequent synthesis report.
Applications should consider demonstrating the following skills in their application:
- Communicating research to non-experts
- Ability to synthesise information
- Leadership skills
- Innovative thinking
- Understanding of the Global Food System
