Sustainable Diets in the Foodservice Industry: Everything You Need to Know
Can the global food system feed a growing population sustainably? For foodservice operators, that question is becoming increasingly urgent.
Sustainable diets are now moving from theory to action across menus, sourcing strategies and nutrition planning. In foodservice, the opportunity is clear: deliver dishes that meet guest expectations, support business goals and reduce environmental impact.
In this article, we look at what sustainable diets are, why they matter and how operators can respond.
What Is a Sustainable Diet?
A sustainable diet takes into account the environmental impact of food from multiple perspectives, including land use, energy use and water footprint1. It is not defined by a single ingredient or a single way of eating. Instead, it looks at how food is produced, sourced, prepared and served.
That means vegetarian, flexitarian, and vegan menus can all contribute to a sustainable diet, depending on their composition and supply chain. In practice, sustainable nutrition is about creating menus that work for people and for the wider food system.
Why are sustainable diets becoming such a key trend?
Sustainability is one of the most important goals facing the food industry today.
By 2050, the global population is expected to reach 9.1 billion people2. More people will live in cities, incomes will rise in many regions, and demand for food will continue to grow. At the same time, the current food system already uses over 30% of ice-free land, 70% of fresh water and 20% of energy globally3. That is a significant challenge for any supply chain.
Agriculture will need to produce substantially more food to meet future demand. Yet there is limited land available, and the current model cannot simply continue at scale without consequences. This is why sustainable eating is becoming central to foodservice strategy.
There are clear reasons for operators to pay attention:
- Environmental pressure is increasing: food production contributes significantly to greenhouse gas emissions and water use. The EAT-Lancet Commission has highlighted the scale of this impact and the need for more responsible food systems4.
- Plant-based protein offers opportunity: compared with animal protein, plant-based proteins generally require less land and water. For example, soy can deliver more protein per acre than beef5, making it a valuable ingredient in sustainable nutrition planning.
- Consumer expectations are changing: guests want menus that feel modern, relevant and responsible. They are more informed, more curious and more likely to choose sustainable food when it is presented well.
- Business goals are aligned: sustainable diets can support wider objectives, from menu differentiation and customer satisfaction to waste reduction and long-term resilience.
Are sustainable diets important in the foodservice industry?
Yes, and the evidence is strong.
According to recent research, almost one-quarter of consumers see foodservice providers as important players in encouraging sustainable eating. That’s because a well-designed menu can guide customers toward dishes that are both appealing and more sustainable, without making the experience feel restrictive or complicated.
That is exactly what matters. Sustainable food must work in real-world service. It needs to be:
- Practical for chefs and kitchen teams
- Appealing to guests
- Consistent in quality
- Commercially viable
- Supported by reliable supply
At Nestlé Professional, our foodservice partners tell us that vegan and vegetarian dishes must deliver on taste, health and sustainability, while still offering strong value for money. That is the benchmark. If the dish feels justifiable, relevant and delicious, it earns its place on the menu.
Sustainable nutrition also plays a growing role here. Operators are increasingly expected to consider the nutritional profile of their menus as well as their environmental footprint. That means balanced recipes, sensible portioning, fibre, protein and a thoughtful approach to salt, sugar and saturated fat.
Katya Simmons, MD, Nestlé Professional UK and Ireland says:
“We, together with our foodservice partners, consider it vital that consumers see vegan and vegetarian dishes delivering on taste, health and sustainability, all whilst being great value for money. This is so customers feel ‘the money I am paying for it is absolutely reasonable, justifiable’.
“We’ve also worked hard to ensure our products meet a number of nutrition targets, such as high in protein; a source of fibre; not high in fat, saturated fat or sugars; and we are working towards salt targets.
“Our nutrition team and development chefs have worked together to develop a range of delicious, balanced recipe ideas under 600kcal; each providing two portions of fruit and vegetables.”
In short, sustainable diets are important because they connect the environmental agenda with customer needs and operational performance.
