Since eating is, in essence, a total social act, the importance of collective contexts in shaping the way we select and consume our food has been recognized. Specifically, in contemporary lifestyles, collective contexts represented by cafeterias, bars, dining halls, fondas, or restaurants shape our food decisions according to supply and demand, but also through the ways food is arranged and the company with whom we eat.
This fact has interested scientists for several years, aiming to identify how these contexts influence our eating patterns and, consequently, to foster interventions that encourage healthier and more sustainable eating habits over time. Based on this, qualitative and quantitative studies have attempted to establish how the conditions of these eating places influence the development of better habits among diners. A recently published study by Graça and others undertook a review of more than 250 scientific articles on the subject, seeking to determine what is currently known and where improvements can be made to promote better habits from this context.
In general, this review sought to understand how interventions are designed—that is, under what criteria people are influenced to adopt better habits, and thus, to establish a clearer framework for what drives changes in eating behavior toward healthier characteristics. Among the approaches scientists use to address these changes, interventions are often aimed at increasing fruit and vegetable consumption, regulating calorie intake, promoting plant-based foods, and reducing animal-based foods. These interventions are based on various models of behavioral change: some focus on providing information and knowledge to influence decision-making, others target environmental changes, from colors to menu design and pricing, affecting the choice of specific dishes. Additional interventions include enhancing the visual appeal of healthier dishes, changing the location where certain dishes are advertised or displayed, offering rewards for choosing specific ingredients, among others.
Among all these ways of intervening in diners’ choices, researchers have concluded that motivation is one of the underlying factors necessary for changing eating habits. Since each person’s motivation is a subjective factor that is difficult to measure in these interventions, the results are highly variable. One gap identified is that interventions rarely take into account the characteristics of the studied population, such as age, gender, socioeconomic level, and other variables that could be decisive in motivating individuals to improve their eating habits. Nevertheless, collective contexts in which food is consumed are definitely a decisive factor in accelerating behavioral changes that lead people to adopt healthier eating and lifestyle habits.
