Deliverable D1.1, reviews evidence for key behavioral and socio-cultural determinants of alternative protein choices among European consumers. More specifically, the report synthesizes empirical evidence for the determinants of the consumer choices of alternative protein food (APF). Specifically, it addresses the associations between APF and: (i) the individual-level determinants (capabilities, perceived opportunities, motivation) from the COM-B model and sociodemographic factors from socio-ecological models of behavior change, such as: age, gender, education, and income, and (ii) indicators of the consumer choices (e.g., intention to eat, buy, pay, acceptance of, intake).
