Planetary Health Episode 10: Nutrition as a Service: Health begins at the dinner table

What if we didn't treat people only when they were sick, but fed them in such a way that they stayed healthy? “Nutrition as a Service” (NaaS) is more than a technological concept. It is an attempt to incorporate nutrition into the infrastructures of the future – not as a cost factor or lifestyle choice, but as a systemically relevant prerequisite for health, resilience, and planetary sustainability.

In the discourse on the Planetary Health Diet, the emphasis has often been on the what: plant-based, less meat, local cycles. But the how is at least as important. How do we organize access to healthy food? How do we personalize recommendations without creating new inequalities? And how do we scale quality in a system that has so far been optimized for quantity? This is where NaaS comes in—as a bridge between individual health knowledge and automated implementation. Since the personal chef with strong preventive skills remains a utopia, new business areas for individualized communal catering are opening up at the interface between wearables and other health data. Or, in the private sphere, through the use of Culinary Processing Units as multifunctional kitchen assistants with linked nutritional optimization based on health data provided via a secure cloud.

NaaS combines personal health data such as genetics, microbiome, and metabolism with digital intelligence. Platforms analyze this information, calculate personalized nutritional profiles, and forward them to automated kitchens. Robots use this information to prepare individually tailored dishes – precisely, scalably, and with consistent quality. Real-time feedback, for example via sensors in wearables, allows this nutrition to be continuously adjusted. What is good for people is no longer a theoretical assumption, but is implemented in concrete terms. This is one way to overcome the mind-behavior gap.

The result is a nutrition system that adapts rather than standardizes, that accompanies rather than prescribes – and that understands health as a dynamic process that must be maintained continuously rather than selectively. NaaS is thus a quiet paradigm shift: away from standardized nutrition for average people – toward individualized health care that begins with food.

At the same time, NaaS opens up systemic potential: if nutrition has a preventive effect, it relieves the burden on health and social systems in the long term. If automated processes reduce food waste, the ecological balance is improved at the same time. And if personalized recommendations lead to greater self-efficacy and more enjoyment, a new culture of eating emerges – one that combines responsibility, mindfulness, and joy.

The Planetary Health Diet reflects a globally applicable target range for healthy and sustainable nutrition. It is understood as a balance between ecological resilience and human health. However, in order to achieve this balance in practice, systems are needed that reduce complexity, support decision-making, and make it suitable for everyday use.

This is where NaaS offers an operational complement: it translates the normative idea of the Planetary Health Diet into concrete, individual proposals for action. It creates a dynamic fit between global orientation knowledge and local, personal implementation. In this way, the Planetary Health Diet can not only exist as a model, but also become effective as an infrastructural practice – scalable, connectable, and adaptive.

But what exactly does NaaS communicate? If we look at the term through a systemic lens, it becomes clear that it is not just a technical service, but a new form of self-description of the food system. This system observes itself – and in doing so develops new structures of expectation. It irritates itself. Because NaaS stands on the threshold between functionally differentiated systems: health, economy, science, politics, environment, and technology. Each of these systems operates with its own code—healthy/sick, pay/don't pay, true/false, legal/illegal, preserving/destroying, functional/dysfunctional—and NaaS attempts to temporarily link these codes without abolishing them.

This linkage creates tensions. While the healthcare system aims for long-term stability, the economic system depends on short-term willingness to pay. The technological infrastructure promises efficiency, but must legitimize itself in relation to political and ethical standards. Nutrition thus becomes a medium of communication for risks, responsibility, and creative possibilities – but not in a neutral sense, rather always within a specific system that observes its environment.

The fact that nutrition is now data-based, personalized, and automated does not change the operational coherence of the systems involved – but it does shift their mutual irritations. Nutrition thus becomes a risk concept: those who eat “wrong” cause costs. Those who eat “right” are acting responsibly. This morality is not an objective truth, but the result of communication – with corresponding consequences for participation, access, and self-interpretation.

Nutrition as a Service could therefore be read as an attempt to stabilize communication about nutrition by offering technical infrastructures that operationalize individual decisions as system expectations. The central distinction shifts: no longer healthy/unhealthy, but appropriate/inappropriate for the profile. The body becomes a source of data, nutrition an adaptive response to algorithmically generated difference patterns.

This raises the question of whether humans become too much of an object of technical control in such a system. When nutrition is no longer experienced but calculated, there is a danger that individual autonomy will be replaced by algorithmic accuracy. What begins as empowerment through personalization can turn into a subtle form of control – especially when decisions are no longer comprehensible but only appear logical within the system.

In addition, the underlying data is highly sensitive. Those who process it gain deep insight into lifestyle, health, needs – and potentially weaknesses. The question of data sovereignty and digital ethics thus becomes a key issue for such an infrastructure. Trust is not created solely through functionality, but through transparency, participation in design, and legally enshrined limitations on access and evaluation.

This form of nutrition generates new self-descriptions: humans are no longer thought of as eating bodies, but as controllable variables in the context of digital supply systems. Whether NaaS makes people more independent or creates new dependencies is not determined by the technology itself, but by how we talk about it, use it, and regulate it. A systems theory approach invites us not to make hasty normative judgments. NaaS is neither the solution nor the problem. It is a form of communication that shows how the food system reassures itself – under conditions of functional differentiation, technological dynamics, and ecological limitations.

To be truly healthy, it is not enough to be fed. That is the level of feed: calorie provision, energy security, pure supply. But health only arises at the level of food – where food unfolds diversity, taste, textures, and culinary culture. Only nourishment closes the circle: a diet that not only satisfies hunger but also nourishes – physiologically, emotionally, microbially, socially, and sensorially. Enjoyment is not a luxury, but the evolutionary biological translation of “this is good for me.” Enjoyment connects the molecular level (nutrition) – including numerous bioactive substances beyond calories – with the experiential level of eating. While feed merely provides calories, nutrition establishes the functionality of physiological systems. Food as medicine describes its preventive or healing effects, but nourishment goes further: It encompasses the complex, holistic concept of nourishment that intertwines taste, identity, well-being, and regeneration.

Perhaps this is precisely where the opportunity lies: thinking of NaaS not as a technological utopia, but as an infrastructural evolution. Not as a substitute for cooking, but as a new form of enabling. Not as a sacrifice, but as an opening. A future in which canteens become places of vitality, in which schools not only teach nutrition, but bring it to life. In which cities, alongside energy and transport networks, understand nutrition as infrastructure – FoodArchitecture.

Because perhaps the healing of our system does not begin with medicine, but with a spoon – and the right system behind it.
