Food Insecurity in people living with Obesity (FIO Food)

At both UK and global levels we need to change dietary patterns to address environmental, health, and inequality challenges. Despite considerable policy intervention, overweight and obesity has continued to rise in the UK, with obesity now a leading cause of death. Obesity is higher in areas of social deprivation and the current UK food system, including governmental policy, does not effectively address this; indeed, current behavioural approaches may even widen the inequalities gap.

The National Food Strategy team have extensively reviewed the UK food system with the remit for planning access “safe, healthy, affordable food; regardless of where they live or how much they earn”. In the detailed report, the key issues of obesity, reducing diet-related inequality and the environmental impact of the food system are described and discussed. The links between food insecurity and development of obesity and the potential effectiveness of interventions to prevent and reduce the impact of diet-induced health harms is not well evidenced in the UK retail food environment.

We address this call for evidence through a novel and multi-disciplinary collaborative approach with co-development as a key feature, through four inter-linked work packages, to combine our knowledge of large-scale population data with an understanding of lived experiences of food shopping for people living with obesity and food insecurity, to develop solutions to improve sustainable and healthier food choices.

Professor Alexandra Johnstone at Rowett Institute at the University of Aberdeen is leading this Strategic Priorities Fund UKRI grant, with an excellent team of academics and food partners.  The high levels of obesity in the UK represent a key public health issue, with 67% of the UK population living with overweight or obesity. Obesity remains a core government priority. The UK has yet to find an effective strategy to help reduce obesity levels, especially among low-income communities. We need better evidence on how we can change food purchasing and consumption behaviours for people living with obesity and food insecurity that can improve their health and wellbeing, while also be sustainable.

Funded by the Biotechnology and Biological Sciences Research Council (BBSRC) Strategic Priorities Fund (SPF), part of UK Research and Innovation (UKRI), we aim to research how the world can make healthy and environmentally sustainable changes to food choices for those living with obesity and facing food insecurity.

The Rowett Institute has over 100 years of experience investigating nutrition and disease process, adapting our research for the needs of the current population.

Our focus is now on addressing what sounds like opposite issues, the overconsumption of food and food insecurity, however the two are very much related. These problems are multi-dimensional, coming with their own complications. Our goal is to identify how we can provide realistic and robust solutions whilst paying close attention to the cost-of-living crisis. Obesity is at the core of many disease processes and is associated with mortality and morbidity. It places a burden on our healthcare system, and it is vital that we make swift progress towards providing solutions.

The terms ‘food insecurity’ and ‘environmentally sustainable’ diets are themselves controversial. The extended FAO definition that refers to household level food insecurity (FI) underpins the Food Insecurity Experience Scale that we are using to identify food insecure participants is, ‘a lack regular access to enough safe and nutritious food for normal growth and development and an active and healthy life. This may be due to unavailability of food and/or lack of resources to obtain food’ (FAO, IFAD, UNICEF, WFP and WHO, 2021). We will use these working definitions below and apply the principles of the Eatwell Guide for a sustainable healthy diet (PHE, 2016).

• Food insecurity (FI) The condition of not having access to sufficient food, or food of an adequate quality, to meet one's basic needs (Oxford Dictionary Definition).
• Sustainable Healthy Diets are ‘dietary patterns that promote all dimensions of individuals’ health and wellbeing; have low environmental pressure and impact; are accessible, affordable, safe and equitable; and are culturally acceptable” (FAO and WHO, 2019).
• Carbon Trust, The Eatwell Guide: A More Sustainable Diet (2016)

POLICY BRIEF: PERCEPTIONS OF SUPERMARKET INTERVENTIONS

In this policy brief, we present bite-size results related to the perceptions of supermarket interventions focused on facilitating healthier and more sustainable food choices. Full document available here. 

WHITE PAPER

In this White Paper, we present the findings from two of the FIO Food project stakeholders’ workshops that we ran at the beginning of 2024. We have co-produced knowledge across academics, stakeholders and consumers' lived experiences to formulate actions for policymakers and healthcare professionals. All of these insights were equally needed to explore potential avenues that can be applied in the food system to promote healthier and more sustainable choices in the food retail environment, particularly among those with greater health risks.

RESEARCH BRIEF: RETAILERS INTERVIEWS

As part of the Work Package 1 deliverables, Prof. Charlotte Hardman and Dr Rebecca Stone conducted a qualitative interview study with seven UK supermarket senior nutritionists, who represented 85% of the grocery market share in the UK. The animation below provides a brief overview of their perspectives, views, and experiences on the acceptability and feasibility of using price/incentivisation as interventions for health and sustainability. 

Working with Patient and Public Involvement (PPI) advocates

WHAT IS CO-PRODUCTION

Co-production of research is one of the key strengths of the FIO Food project. It is defined as the process in which researchers, practitioners and members of the public collaborate to develop research together. This approach can help to strengthen public involvement as well as create and implement more relevant and applicable solutions (Farr et al, 2021). Our Team has developed a video to explain what it means to be a Patient and Public Involvement (PPI) member in health research co-production. We hope this video will help in the recruitment process.

HOW TO WORK WITH PEOPLE WITH LIVED EXPERIENCE OF DIETARY INEQUALITIES

Dr Charlotte Hardman (FIO Food Team) and Dr Rachel Loopstra (University College London) ran one of the TUKFS workshops in Sheffield. The workshop was a discussion session on dietary inequalities/food insecurity, which aimed to identify synergies between TUKFS projects and to agree on ways of working together to increase the scope and impact of research. A vignette from the workshop includes infographics which illustrate:

• How to engage and collaborate with people with lived experience of food insecurity?
• How to collect robust data to monitor the extent of dietary inequalities 
• What interventions currently exist to tackle household food insecurity in the UK?
• How can the TUKFS projects best work together to create joined up impact?

CHALLENGE POVERTY WEEK 

The FIO Food Team together with Aberdeenshire Council hosted a PPI workshop on the 4th of October 2022 at the Rowett Institute, University of Aberdeen to discuss diet inequalities and contribute to the Challenge Poverty Week campaign The workshop was run by Prof Alex Johnstone and Prof Flora Douglas and had 31 attendees representing the Aberdeenshire consumers. Challenges related to the cost of living crisis were discussed and barriers in purchasing foods that would help to maintain a healthy diet. A vignette was developed based on discussion themes which was shared with the project team to provide insights for the intervention, as well as with project stakeholders.

LIVED EXPERIENCE INTERVIEWS

In July 2023, FIO Food delegates contributed to the parliamentary event showcasing the FIO Food project, providing a summary of the FIOFood project objectives and preliminary insights to show opportunities in co-creation to support systems change. Our PPI advocates - Jennie and Kathleen - shared their valuable lived experience insights of living with obesity and/or food insecurity. The interviews can be viewed below.

MoreLife provide programmes and services to individuals that will help them change their behaviours and make a difference to their overall health and wellbeing. Their aim is to make the lives of individuals healthier, through healthy lifestyle behavioural interventions such as weight management, giving up smoking, NHS Health Checks, healthy eating or improved physical activity. They work with individuals on their own, with their families, within groups from the local community, school or workplace.

Ms Nilani Siratharan, Healthy Living Manager, at Sainsbury’s plc

The Sainsbury’s Group bring notable added value to this project. They will share, their nectar card loyalty records with the research team for studying food purchasing patterns. They have around 1.7 million primary shoppers who are defined as low affluence (based on income, tenure, and savings). We will be collaborating with Sainsburys so that we can tackle the cost-of-living crisis directly with those involved in the supply chain. We will be analysing Nectar customers food habits and utilising survey’s, focus groups and initiating a national digital intervention study.
