Sustainability and health effects of small pelagic fish

To address growing environmental and health concerns related to current food production and consumption patterns we are advised to transition to predominantly plant-based diets. While eating more plant-based whole foods is associated with better health, animal-source foods remain important sources of essential micronutrients that are not available from plants. Norway owns a plentiful resource, small pelagic fish, that is rich in these nutrients, affordable, and has a low carbon footprint. The RCN funded project Unlocking the environmental and nutritional potential of small pelagic fish: A path towards sustainable food systems explores how Norway can use its small pelagic fish catch to benefit public health in the transition towards more environmentally friendly diets.

Predominantly plant-based diets are increasingly recognized for their benefits to both human health and the environment. In many Western countries, especially among women and younger adults, plant-based and meat-reduced diets are becoming increasingly popular. While such diets offer numerous health advantages, they can also present nutritional challenges. Several essential micronutrients are either absent, present in low concentrations, or less bioavailable in plant-based foods. As a result, nutritional deficiencies are more common among vegetarians and vegans, which can have serious health consequences in both the short and long term.

Norway owns a plentiful resource, small pelagic fish, which are rich in the key nutrients often lacking in plant-based diets. These fish are also affordable and have one of the lowest carbon footprints of all animal-source foods, second only to farmed blue mussels. At the same time, Norway is the world’s leading producer of farmed salmon, a sector that relies heavily on small pelagics as a feed ingredient. Globally, 70–80% of the small pelagic catch is not used for direct human consumption. Instead, most of it is processed into fishmeal and fish oil to support the growing aquaculture industry, as well as increasing demand from the pet food and pharmaceutical sectors.

This project puts small pelagic fish into a food systems perspective and aims to provide tangible solutions for how Norway can utilize this resource to safeguard public health in the transition towards more environmentally sustainable diets, while at the same time contributing to its national goal of lowered greenhouse gas emissions, and spurring innovation towards more nutritious meat alternatives.

EAT-Lancet report at the Stockholm Food Forum

On October 3–4, Gabriella Ljungström attended the launch of the new EAT‑Lancet Commission Report, Healthy, Sustainable, and Just Food Systems, at the Stockholm Food Forum.

The report emphasizes a largely plant-based diet while recognizing seafood as the only animal-sourced food that should increase in production due to its nutritional benefits and relatively low environmental footprint. To achieve this, it calls for rebuilding wild fisheries and scaling responsible aquaculture, highlighting well-managed fisheries as essential for sustainable food systems.
