Encouraging Nordic citizens to adopt healthier and more sustainable dietary habits requires a coordinated effort to shift long-established behaviours. Based on an extensive review of scientific literature of the topic, we have identified how multiple factors can influence people's food choices, including supply and availability, marketing, social norms, education, income, and social status. Any measures and incentives introduced to promote behaviour change should consider these factors to be effective.
Product choice architecture. Making plant-based and healthy options more accessible is documented to make a difference. Product placement, portion arrangement and presentation are important to make citizens choose healthy and sustainable foods. Nudging interventions can achieve higher effectiveness through public-private collaboration, and nudging has gained widespread acceptance due to its low implementation costs.
