Despite shifts towards vegan and vegetarian diets in Western cultures, demand for animal protein persists. Alternative protein sources are required to nourish the growing world population without compromising on sustainability. Researchers at the University of Göttingen and the University of Alberta, Edmonton, Canada, investigated consumer preferences of alternative protein sources. Specifically, the researchers looked at the effect of information regarding algae and insects in the food chain. The results were published in the journal Food Policy.
