Increasing legume consumption will significantly contribute to sustainable and healthy agrifood systems; but this breakthrough also depends on the increasing variety of legumes that are used. We began with an analysis of food product innovations containing legumes, launched between 2010 and 2020 in North America and Europe. Using the Global-New-Product-Database from Mintel, we compared the development and market positions of soya and pulses. Even when excluding foods containing soya-based minor ingredients (i.e., lecithine) we observed that food product innovations containing soya represent almost six times more than those containing pulses. These results suggest that in addition to being a dominant crop in animal feed, soya is becoming a major global food crop when compared with the low development of other grain-legumes. This makes us question to what extent the market can sustain cultivated biodiversity and overcome the path-dependency that still favours major global crop development while neglecting others.
