When discussing seafood sustainability, the conversation often focuses on environmental impact or production practices. While these aspects are essential, they do not fully capture the broader value of seafood within sustainable food systems.
Seafood is not only a resource to be managed responsibly—it is also a source of essential nutrients that support human health. Recognising this, the VeriFish project integrates a Nutrition & Health Pillar into its sustainability framework, ensuring that dietary benefits are considered alongside environmental and socio-economic factors.
A three-pillar approach to sustainability
VeriFish defines seafood sustainability through three interconnected pillars:
- Environmental
- Socio-economic
- Nutrition & Health
Each pillar addresses a different dimension of sustainability and relies on distinct types of evidence. The Nutrition & Health Pillar focuses on how seafood contributes to balanced diets and public health, complementing the environmental and human dimensions of the framework.
By combining these perspectives, VeriFish provides a more complete understanding of what sustainability means in practice.
Assessing nutritional value in a structured way
The Nutrition & Health Pillar evaluates seafood based on its nutritional composition, including:
- protein content
- long-chain omega-3 fatty acids
- vitamins and minerals
To make this information comparable and accessible, VeriFish introduces a Nutrient Density Score. This score reflects the contribution of nutrients per 100 grams of seafood to the daily recommended intakes defined by the European Food Safety Authority (EFSA).
In addition, the framework highlights nutrients that are present in significant amounts, allowing users to easily identify the key nutritional strengths of each species.
This structured approach helps translate complex nutritional data into clear and usable information.
Why seafood matters for human health
Seafood plays a unique role in supporting healthy diets. It provides nutrients that are often under-consumed in modern populations, including:
- long-chain omega-3 fatty acids, which support heart and brain health
- iodine and selenium, essential for metabolic and immune functions
- vitamin D and vitamin B12, critical for overall well-being
By making these benefits visible, VeriFish helps connect sustainability not only to environmental responsibility, but also to public health outcomes.
From data to informed choices
One of the key challenges in nutrition communication is accessibility. While nutritional data exists, it is often difficult for non-specialists to interpret or apply.
VeriFish addresses this by integrating the Nutrition & Health Pillar into its main outputs:
- the VeriFish web application, where users can explore nutrient scores and species-specific information
- the VeriFish Guidelines, which provide recommendations on how to communicate nutritional and sustainability information clearly and responsibly
These tools are designed to support decision-making across the value chain—from consumers choosing what to eat, to producers and retailers communicating product value, to policymakers shaping food systems.
Linking sustainability and health
The inclusion of nutrition within the VeriFish framework reflects a broader shift in how sustainability is understood.
A sustainable food system must not only minimise environmental impact but also contribute positively to human health. By integrating nutritional indicators, VeriFish ensures that seafood sustainability is assessed in a way that reflects both ecological and societal needs.
From understanding to action
Sustainability is not a fixed label. It is the result of informed choices made by individuals, organisations and institutions.
By providing structured, transparent and evidence-based information, the VeriFish Nutrition & Health Pillar helps users navigate these choices more effectively.
Because sustainable seafood is not only about protecting resources—it is also about supporting healthier people and more resilient food systems.
