Blue foods have great potential to contribute to a sustainable food system. However, for this to happen, we need to consume much more of so-called extractive species, like algae, which most of us currently only encounter in sushi. Algae offer many advantages: their cultivation does not compete with farmland, and they yield abundant harvests. Algae are also an excellent source of nutrients, including minerals, fiber, and protein. Despite this, algae remain a niche product. Axfoundation aims to change that by developing new, tasty algae-based foods and making seaweed a staple in everyday diets.
