The Emerging Framework for the Future of Food
Last update: 05/06/2026
Sustainable diets are becoming a new reference point for how food systems are evaluated by policymakers, retailers, and increasingly by consumers. What was once primarily addressed through voluntary initiatives is now evolving into a structured framework that is expected to influence future regulations, product requirements, and market access. The global food system is estimated to contribute around one-third of greenhouse gas emissions and is a major driver of deforestation, biodiversity loss, and land degradation. At the same time, current dietary patterns are associated with a growing burden of diet-related diseases, such as diabetes, cardiovascular diseases, and certain cancers, highlighting the need to address both environmental and health impacts in a more integrated way.
At its core, the concept of sustainable diets brings together nutritional quality and environmental impact, alongside considerations such as affordability, accessibility, and cultural acceptability. Rather than focusing only on individual product attributes, it looks at the overall contribution of foods to both human health and planetary boundaries. The scope also encompasses broader issues like food safety (for example, protecting consumers from emerging microbial hazards and chemical contaminants like PFAS or microplastics), sensory quality, supply chain resilience, and animal welfare and human rights across the value chain.
This shift is gaining momentum across several fronts. Policy initiatives, particularly in Europe, are increasingly integrating sustainability into dietary guidelines and food system strategies. At the same time, retailers and food service actors are beginning to translate these principles into portfolio targets, product reformulation strategies, and front-of-pack information schemes. In parallel, evolving consumer expectations are reinforcing the demand for food products that are both healthy and environmentally responsible.

fair and affordable; nutritionally adequate, safe and healthy; while optimizing
natural and human resources.

For food companies, this trend has concrete implications across functions:
- Product development and reformulation: Companies are expected to optimize both nutritional profiles and environmental performance, for example through ingredient choices, protein diversification, and recipe adjustments.
- Data and assessment capabilities: There is a growing need to combine nutritional data with environmental metrics (e.g., Life Cycle Assessment) at the product level, enabling more holistic evaluation and decision-making.
- Claims and communication: Positioning products as “healthy and sustainable” requires robust substantiation, as scrutiny on both nutritional and environmental claims continues to increase.
- Cross-functional integration: Addressing sustainable diets requires closer collaboration between R&D, quality, regulatory, and sustainability teams, reflecting its role as an emerging compliance and business topic.
Importantly, sustainable diets also introduce trade-offs that need to be carefully managed. Improvements in environmental impact do not always align with nutritional outcomes, and vice versa. Navigating these complexities requires transparent methodologies and science-based approaches.
Looking ahead, sustainable diets are expected to shape both regulatory developments and market expectations. As a result, the ability to assess, balance, and communicate nutritional and environmental performance at the product level is becoming a key capability for food companies seeking to remain competitive and compliant in a rapidly evolving landscape.
