Abstract
Wan Mak, head of nutrition and dietetics at Sodexo UK & Ireland, explores the concept that food isn’t just fuel as she argues it is ‘an experience, a science and a choice’.

At Sodexo, we use that science to craft meals that nourish, delight and support both people and the planet. You can see how serious we are about health and nutrition by the fact that Sodexo is the world’s largest employer of dietitians, with 5,402 experts globally, bringing deep food expertise to diverse markets.

With over 30 years of experience, I’ve dedicated my career to improving food choices and nutrition education. As a registered dietitian and nutritionist, I’ve seen firsthand how the right approach to nutrition can transform lives. That’s why, at Sodexo, the nutritional composition of every dish we serve is carefully considered.

Our first Nutrition Report showcases how our dietitians and nutritionists, chefs, and supply chain experts collaborate to create meals that make healthier eating effortless. From military bases to schools, hospitals to corporate offices, we design menus that blend nutrition with taste and sustainability with convenience.

Making the healthy choice the easy choice

Our research shows that people want nutritious, sustainable meals but not at the expense of taste, affordability, or convenience. That is why we review over 7,000 recipes a year, tracking portion sizes, salt and sugar levels, ingredient quality and nutrient density. Whether it is boosting fibre content in or tailoring meals for active military personnel, we design food that meets real-world needs.

While our data shows more customers are choosing healthier options, national trends remain concerning. In England, childhood obesity in reception-age children rose to 9.6% in 2023-24, and in Ireland, up to 7% of children in disadvantaged areas live with obesity. That is why our work is not just about better meals - it is improving public health.

Nutrition that fuels the mind and body

Good food does not just fuel the body, it powers the mind. Research shows a potential link between gut health and cognitive function, which is why our meals prioritise fibre-rich foods like whole grains, fruits, and vegetables to support the gut.

Equally important is the role of food in social connection. Studies show that people who eat together are happier and have stronger support networks. From school dining halls to workplace dining spaces, we create environments that encourage interaction - because food is about more than just eating.

Sustainability

Sustainability is not an option, it is an expectation. Our 2024 Sustainable Food Barometer found that 35% of UK consumers associate sustainable food with better nutrition. But they also told us they need help – whether through recipe inspiration, clearer labelling, or accessible plant-based options.

This is a real motivation for us to make it easier. We are using carbon labelling to help customers make informed choices and by 2030, 70% of our main meals will be low carbon.

Food safety and choice

From allergens to ultra-processed foods (UPFs), consumers want clarity. Our Nutrition and Dietetics team ensures every dish meets strict nutritional and allergen standards, providing clear labelling and safe preparation processes.

The UPF debate highlights a need for better consumer guidance. While some ultra-processed foods are linked to health risks, others – like fortified wholegrain cereals– offer key nutrients. Consumers need clarity, not confusion, and by working together with Government and the industry we can establish evidence-based definitions.

Looking ahead

Our mission is simple: make nutritious, sustainable, and delicious food the easy and obvious choice. Through science, innovation, clearer information, and a deep understanding of consumer trends, we are shaping a food future that supports health, wellbeing, and the planet because good food is not just about what is on the plate, but the impact it has on our bodies, our communities, and our world.
