Food manufacturing companies in the UK use three main strategies to help workers eat healthier: changing what food is available (48% of programs), teaching nutrition education (37%), and using reminders and cues (52%). According to Gram Research analysis of 19 studies and 11 company surveys, about 47% of these programs successfully improve what employees eat, though success depends heavily on having adequate budget and support from company leadership.
A new study looked at how food manufacturing companies in the UK are helping their employees eat better and stay healthier. Researchers reviewed 19 scientific studies and surveyed 11 food companies to understand what programs work best. They found that companies use three main strategies: changing the food environment (like offering healthier options), teaching nutrition education, and using reminders and cues. The biggest challenges are getting employees interested and finding enough time, money, and staff to run these programs. The study shows that while some programs work, many companies need more support and resources to make healthy eating easier for their workers.
Key Statistics
A 2026 systematic review of 19 studies found that 52% of food manufacturing nutrition programs used reminder and cue strategies, while 48% focused on changing the food environment, and 37% provided nutrition education.
According to a 2025 UK industry survey of 11 food manufacturing companies, 62% of organizations prioritized changing the food environment as their main nutrition intervention strategy for employees.
Research reviewed by Gram found that 47% of nutrition and wellbeing interventions in food manufacturing reported positive changes in employee dietary intake, while budget availability and senior management support were cited as enablers by 45% of companies.
A scoping review of food manufacturing nutrition programs identified that 42% of implementation barriers occurred at the employee level (engagement, language, resistance to change) and 33% at the organizational level (time, staffing, funding, space).
The Quick Take
- What they studied: How do food manufacturing companies help their workers eat healthier foods and maintain good nutrition?
- Who participated: The research reviewed 19 published studies (6 from the UK) and surveyed 11 UK food and beverage manufacturing companies, mostly large organizations with hundreds of employees.
- Key finding: Companies use three main approaches: changing the food environment (48% of programs), teaching nutrition knowledge (37%), and using reminders and cues (52%). About 47% of programs showed positive changes in what employees ate.
- What it means for you: If you work in food manufacturing, your company may offer nutrition programs, but they’re still not common enough. The biggest barriers are lack of employee interest, language differences, and limited company resources like time and money.
The Research Details
Researchers used two methods to understand this topic. First, they conducted a ‘scoping review,’ which means they searched five scientific databases from 2000 to 2025 for studies about nutrition programs in food manufacturing. They found 19 peer-reviewed studies and 12 case studies that met their criteria. Two researchers independently reviewed each study to make sure the information was accurate.
Second, they created an online survey that was sent to UK food and beverage manufacturing companies between March and May 2025. Eleven companies responded, with most being large organizations. The researchers then combined the information from both the scientific studies and the company survey to create a complete picture of what’s happening in the industry.
The researchers also used something called the ‘Behaviour Change Technique Taxonomy,’ which is a framework that helps categorize different strategies used to help people change their eating habits. This allowed them to organize all the different programs into three main categories: changing the food environment, teaching knowledge, and using reminders.
This approach is important because it combines what scientific research shows works with what companies are actually doing in real life. By looking at both published studies and surveying actual companies, the researchers got a complete picture of the gap between what science recommends and what’s actually happening in UK food factories. This helps identify where companies need more support.
This study is a systematic review, which is considered high-quality research because it follows strict rules for finding and analyzing studies. The researchers had two people independently review studies to reduce bias. However, the survey only included 11 companies, which is a small number, so the survey results may not represent all UK food manufacturers. The limited number of published studies (only 19) also suggests this is an understudied area.
What the Results Show
The research identified three main strategies that food companies use to help employees eat better. The most common approach (52% of programs) uses ‘association’ techniques—things like putting healthy snacks in visible places, sending reminder emails about nutrition, or posting signs about healthy eating. The second most common strategy (48%) involves changing the food environment itself, such as offering more nutritious options in the cafeteria or removing unhealthy vending machines. The third approach (37%) focuses on teaching employees about nutrition through classes, workshops, or educational materials.
When researchers looked at whether these programs actually worked, they found that about 47% of programs reported positive changes in what employees ate. This means roughly half of the programs showed measurable improvements in employee nutrition. However, the other half didn’t show clear benefits, suggesting that not all programs are equally effective.
The survey of actual UK companies revealed slightly different patterns. Most companies (62%) focused on changing the food environment, while fewer used teaching (21%) or reminder strategies (21%). This suggests that companies find it easier to change what food is available than to change employee behavior through education or reminders.
The study also identified what helps companies succeed. Budget availability and strong support from senior management were equally important, with 45% of companies citing each as a key enabler. This shows that money and leadership commitment are crucial for successful programs.
The research revealed important barriers that prevent more companies from implementing nutrition programs. At the employee level (42% of barriers), companies struggle with getting workers interested, language differences among diverse workforces, and employee resistance to changing eating habits. At the organizational level (33% of barriers), companies face challenges with limited time, not enough staff, insufficient funding, and lack of physical space for programs. Some companies (25%) reported facing both employee and organizational barriers simultaneously.
According to Gram Research analysis, this is one of the first comprehensive reviews of nutrition programs specifically in food manufacturing. Previous research has looked at workplace wellness programs in general, but this study fills a gap by focusing on the food industry specifically. The finding that only 47% of programs show positive results is consistent with broader workplace wellness research, which shows that many programs don’t achieve their intended outcomes without proper implementation and employee engagement.
The study has several important limitations. Only 19 peer-reviewed studies were found, which is a small number, suggesting this area hasn’t been well-researched. The survey only included 11 companies, and 82% were large organizations, so the results may not apply to smaller food manufacturing businesses. The study only looked at UK companies, so findings may not apply to other countries. Additionally, many of the studies reviewed only measured whether employees’ eating changed, not whether they actually became healthier overall. Finally, the survey was conducted online, which may have excluded companies without good internet access or those less interested in nutrition programs.
The Bottom Line
If you work in food manufacturing, encourage your company to implement nutrition programs that combine multiple strategies—changing the food environment, providing education, and using reminders. Evidence suggests this combination approach is more effective than using just one strategy. Companies should also ensure they have adequate budget and visible support from senior leadership. For employees, take advantage of any nutrition programs your company offers, as research shows they can help improve eating habits. Confidence level: Moderate, based on 47% of programs showing positive results.
Food manufacturing employees should care about this research because it shows what types of programs are most likely to help them eat better at work. Food company managers and HR departments should care because it identifies barriers they can address and enablers they should prioritize. Policymakers should care because it shows that more support and resources are needed to make workplace nutrition programs more common and effective.
Most studies reviewed showed changes in eating habits within 3-6 months of program implementation. However, maintaining these changes long-term requires ongoing support and reinforcement. Companies should expect to see initial results within a few months but should plan for continued investment to keep employees engaged.
