Persuasion in culinary discourse is deeply embedded in cultural traditions, making the promotion of vegan cuisine a particularly revealing case of rhetorical adaptation. Although veganism is often presented as a universal response to global challenges such as climate change, public health, and animal welfare, its persuasive force depends largely on the culinary values and symbolic meanings attached to food within individual cultures. Consequently, effective vegan advocacy does not rely on a single rhetorical strategy but on culturally situated appeals that resonate with local identities and eating practices.

In Italy, where cuisine constitutes an important element of national identity and cultural heritage, vegan persuasion frequently emphasizes continuity rather than rupture. Instead of portraying veganism as a radical alternative, communicators often reinterpret traditional Mediterranean dishes, highlighting regional vegetables, legumes, and olive oil while presenting plant-based adaptations as authentic extensions of established culinary traditions. Here, persuasion relies heavily on ethos rooted in culinary expertise and on narratives of authenticity, quality, and gastronomic pleasure.

In Germany, by contrast, vegan discourse is more closely associated with sustainability, environmental responsibility, and consumer awareness. Persuasive messages frequently draw upon scientific evidence, ecological arguments, and technological innovation, framing vegan products as rational, modern, and ethically responsible choices. The dominant rhetorical appeal is logos, reinforced by institutional credibility and environmental ethos.

In Poland, where meat remains strongly associated with hospitality, family traditions, and national cuisine, vegan persuasion encounters greater cultural resistance. Consequently, rhetorical strategies often seek to reduce confrontation by emphasizing familiar flavours, affordable ingredients, and gradual dietary change rather than moral condemnation. Campaigns increasingly frame vegan meals not as a rejection of Polish culinary identity but as creative reinterpretations of traditional dishes, thereby minimizing the perceived conflict between innovation and heritage.

These national differences demonstrate that culinary persuasion cannot be understood independently of cultural context. Vegan discourse succeeds not by promoting identical arguments across societies but by adapting rhetorical appeals to local traditions, collective memories, and food-related identities. In this sense, persuasion in culinary discourse exemplifies the fundamentally rhetorical principle that the effectiveness of an argument depends not only on its content but also on its audience and cultural situation.
