Inserting visual cues on snack bags could help consumers master portion control, and recognise when it’s time to stop eating.
Describing the mechanism as “edible stop signs,” a team of researchers from Cornell University has proposed that adding visual markers on food packages could help people recognise serving size.
“People have a general tendency to consume whatever is put in front of them if it is palatable,” explained Brian Wansink, Cornell Food and Brand Lab director, in a statement.
“There is an increasing amount of research that suggests that some people use visual indication — such as a clean plate or bottom of a bowl — to tell them when to stop eating,” he added.
“By inserting visual markers in a package of snack food, we may be helping consumers to monitor how much they are eating, and interrupt and correct the semiautomated eating habits they possess,” said Wansink.
