"It is shown that producing [consumer-generated images] causes a momentary active delay in consumption, which increases the savoring associated with consumption of pleasurable (i.e. indulgent) foods and, in effect, increases attitudes and taste evaluations of the experience when consumption actually takes place," the researchers said in the study's abstract. But most importantly, the researchers discovered the same effect with healthier foods, too, which means you might eat them more often.
"When descriptive social norms regarding healthy eating are made salient, CGI can also lead to more favorable outcomes for less pleasurable (i.e. healthy) foods," the researchers said.
