Abstract

Abstract: The revised Canada's food guide released in 2019 promotes the consumption of plant-based protein foods (PBP). Yet, older adults consume little of them. This qualitative study aimed to identify older adults' beliefs about consuming PBP and to assess differences in beliefs by gender and baseline PBP consumption. Recruitment was done to obtain an equal number of men and women, 20 PBP-consumers and 40 non-consumers. Each participant completed an online questionnaire collecting sociodemographic data and took part in an individual semi-structured interview based on the Theory of Planned Behavior. A thematic analysis was performed using the Nvivo software. Health benefits, good taste and protecting the environment were perceived as advantages of consuming PBP, whereas difficulty digesting and not liking the taste were reported as disadvantages. Family members were frequently named as people who would approve and/or disapprove the consumption of PBP. Having more knowledge about PBP would facilitate consumption, while lack of motivation to change eating habits and lack of knowledge on how to prepare PBP meals were perceived barriers. Several differences in beliefs by gender and baseline PBP consumption were observed. Future interventions should focus on the beliefs that were identified as important to older adults (i.e., health benefits and food preparation skills), and should be tailored to their gender and PBP consumption.
