Do social norms affect intended food choice?

Area of Science:

• Behavioral Science
• Public Health Nutrition
• Social Psychology

Background:

• Dietary choices are influenced by multiple factors, including social norms, cost, and health concerns.
• The perceived importance of social norms in dietary decisions is not well understood.
• Understanding normative influences is crucial for designing effective public health interventions.

Purpose of the Study:

• To assess the perceived importance of social norms versus cost and health on dietary choices.
• To experimentally evaluate the impact of social norm information on intended fruit and vegetable consumption.

Main Methods:

• A two-stage study design involving home-based interviews with 1083 participants (46% men, 54% women).
• Stage one compared the perceived importance of normative influences, cost, and health.
• Stage two was an experimental study testing the effect of providing social norm information on dietary intentions.

Main Results:

• Participants rated health (M=3.4) and cost (M=2.7) as more important than social norms (M=2.1) in dietary choices (p<0.001).
• Experimental data revealed that normative information positively influenced men's intentions to consume fruits and vegetables (p=0.011).
• Health or cost information did not significantly affect intentions, and no interventions impacted women's intentions.

Conclusions:

• Individuals exhibit low awareness of social norms' influence on their dietary intentions.
• Providing information about social norms can demonstrably impact dietary intentions, particularly in men.
• Health promotion strategies may be more effective by emphasizing the prevalence of healthy lifestyle adoption rather than focusing on unhealthy behaviors.
