good nutrition at work

Short-Term Impact: Boosting Productivity and Reducing Absence

For UK businesses, the immediate return on investment (ROI) from promoting good nutrition is realised through improved daily productivity and reduced sickness absence, directly mitigating national economic drains. Lost economic output due to sickness and ill-health already costs the UK economy over £100 billion per year. A key driver of this loss is poor diet, which results in significant employee presenteeism (working while ill and unproductive) and absenteeism.

Specific research highlights that:

• Employees with unhealthy diets are 66% more likely to experience a loss in productivity (Brigham Young University).

• Poor eating habits in the UK workforce are estimated to cost employers around £17 billion a year in lost working days (Gary Baverstock Nutrition).

By investing in wellness programs that include nutritional education, UK employers can tap into the proven average ROI for general well-being initiatives of £5 for every £1 invested, largely driven by gains in productivity and reduced short-term absence (Deloitte, 2022).

Long-Term Impact: Containment of Economic Cost and Talent Retention

The long-term case for nutrition is tied to containing the staggering national cost of diet-related chronic illness. The indirect cost of lost productivity from people who are too sick to work due to diet-related illness is estimated at £116.4 billion annually in the UK, forming part of the total £268 billion annual cost of unhealthy food habits (Food, Farming and Countryside Commission). These chronic conditions—like Type 2 diabetes and cardiovascular disease—are often preventable through diet, yet they drive up corporate healthcare and long-term absence costs.

Strategic investment in proactive, nutritional support helps UK businesses:

• Reduce Healthcare Burden: Mitigate the substantial increase in long-term sickness, which is set to cost the UK economy an estimated £66.3 billion a year by 2030 in lost productivity (Zurich UK).

• Secure Talent: Demonstrate care for employee health, which is a major factor in attracting and retaining staff. The overall economic value of improved employee wellbeing (which includes nutrition) could be up to £370 billion per year for the UK economy, with improved retention and reduced attrition being major financial components (McKinsey Health Institute).

In summary, supporting good nutrition is no longer a 'nice-to-have' perk; it is a critical strategy for the UK employer to control costs, maximise productivity, and secure a resilient workforce for the future.

Immediate Benefits: Energy, Focus, and Mood

• Boosted Productivity and Focus: Choosing a nutrient-rich diet (complex carbs, healthy fats) sustains energy, helping to minimise the mid-afternoon slump and improve cognitive function.

  • Evidence: UK employees with unhealthy diets are 66% more likely to experience a loss in productivitycompared to well-nourished peers (Brigham Young University).

• Stronger Mental Resilience: Good nutrition helps regulate hormones (like cortisol) and provides the foundation for better mental health, offering a buffer against workplace stress.

  • Evidence: The onset of a new mental illness can lead to an average annual earnings fall of approximately £2,200 for a working-age person, highlighting the financial value of proactive mental well-being (IPPR Commission on Health and Prosperity).

• Reduced Sickness: A balanced diet strengthens the immune system, leading to fewer sick days and less time lost to common illnesses.

  • Evidence: UK employees with poor nutrition scores report 50% more sickness absence compared to those with good scores (vielife UK Study).

Long-Term Benefits: Health, Wealth, and Quality of Life

• Financial Security from Health: By significantly reducing the risk of diet-related chronic diseases (like Type 2 diabetes and heart disease), you safeguard your future health and avoid massive personal healthcare costs.

  • Evidence: Ill health among the working-age population costs the individual (via lost earnings) and the UK economy an estimated £150 billion per year in lost output, illustrating the huge financial burden of being unwell (Oxera).

• Protection of Earnings: Maintaining health and avoiding long-term absence protects your income and career progression.

  • Evidence: The total cost of workplace injury and ill health in the UK for 2023/24 was £22.9 billion, with individuals bearing the majority of these costs (HSE).

• Improved Longevity and Quality of Retirement: Investing in diet now means a higher chance of remaining healthy and active for longer, making the most of your later working years and retirement.

  • Evidence: Malnutrition and related illnesses cost the UK health and care system an estimated £22.6 billion a year, reflecting the substantial cost of managing long-term, diet-related conditions (The King's Fund).
