The study by the Food Farming and Countryside Commission looked at the cost of healthcare, welfare and productivity issues related to what we eat.

The cost of the UK’s unhealthy food system amounts to £268 billion every year, according to a report.

The Food Farming and Countryside Commission (FFCC) report calculated the direct and indirect impact of diet-related ill health by combining the cost of healthcare and social care, welfare spending, productivity losses and the human consequences of chronic disease, and identifying what proportion relates to food.

The food-related cost of chronic disease in the UK includes £67.5 billion in healthcare, £14.3 billion in social care, £10.1 billion in welfare, productivity at £116.4 billion and £60 billion that can be linked to the chronic disease attributable to the current food ecosystem, the research states.

Prof Tim Jackson, the director of the Centre for the Understanding of Sustainable Prosperity at Surrey University, who carried out the analysis, said: “The connection between diet and health is often discussed, but the economics of that link are staggering.

“When we factor in the health impacts, we discover that the true cost of an unhealthy diet is more than three times what we think we’re paying for our food.
