Read Abstract

The term "sustainable food" defines food that is produced using methods that reduce environmental impact (lower carbon emissions, reduced water consumption, responsible use of resources, regenerative agriculture, etc.) while "alternative foods" define food sources that can substitute classic products (meat, milk, animal proteins), often being developed to respond to growing global demand and resource problems. Identifying foods that are both sustainable and alternative is a major challenge, an aspect that is discussed in the following paper. Globally, trends in sustainable and alternative foods show an accelerated growth of the market for plant-based and cultured proteins, supported by technological innovations such as modern fermentation and biotechnology, which reduce resource consumption and emissions. At the same time, governments are starting to play an active role through major investments in research and public policies – from the European Union’s “Farm to Fork” strategy, to national plant-based food plans (e.g. Denmark, South Korea) and regulations for cultured meat (Singapore, USA, Israel). While some solutions, such as insect consumption, face cultural resistance and economic barriers, there is a growing consensus that transforming the global agri-food system is necessary to reduce climate impact, diversify food sources and ensure long-term food security. In order to outline an adequate response to these requirements, this paper aims to present the main categories of sustainable and alternative foods, to characterize them both from a nutritional and sustainability perspective, as well as to highlight the current regulatory framework applicable to their introduction on the market.
