Toward Nutritionally Sound Plant-Based Meat Analogues: Expert Consensus from a Delphi Study.

Plant-based diets are increasingly recognized for their potential health benefits, reduced environmental impact, and alignment with ethical concerns related to animal welfare. Plant-based meat analogues (PBMAs), formulated using alternative vegetable protein sources, can contribute to the nutritional adequacy of such diets while supporting consumer adherence by replicating the sensory characteristics of conventional meat products. This study aimed to establish evidence-based nutritional recommendations for the formulation of nutritionally balanced PBMAs through expert consensus, using a modified Delphi method. Consensus was achieved for 12 nutritional recommendations across three stakeholder groups: (i) academic researchers; (ii) representatives from scientific societies, non-governmental organizations, civil society, and government agencies; and (iii) industry stakeholders involved in PBMA production. Recommendations focused on limiting nutrients of concern-such as sodium and saturated fats-were unanimously endorsed by all groups. Additionally, consensus was reached on recommendations emphasizing the inclusion of ingredients that ensure an adequate intake of essential nutrients, including proteins, fiber, vitamins, and minerals. Among the six proposed regulatory recommendations, three achieved consensus. The resulting set of nutritional recommendations offers a valuable framework to support the food industry in developing PBMAs that align with consumer expectations for health, nutrition, and sustainability. Moreover, these recommendations can play a pivotal role in assisting regulatory authorities in defining identity and quality standards for PBMAs.
