Scenarios illustrating change in eating behaviour assuming increase in social influence and purchasing power. Dark green color represents students who bring healthy food, light green represents students who purchase healthy food, orange color represents students who bring unhealthy food and red color represents students who purchase unhealthy food items. The size of the CA grid is fixed to 40×40, which defines the number of students. The parameter exerting negative influence, N=0.01 is constant across all simulations.
