Most Of The World Belongs To The Clean Plate Club – Except Children
Summary by Brian Wansink, PhD, Cornell Food and Brand Lab
If you’re a member of the Clean Plate Club – you eat pretty much everything you put on your plate – you’re not alone! A new Cornell University study shows that the average adult eats 92% of whatever he or she puts on his/her plate. “If you put it on your plate, it’s going into your stomach,” says Brian Wansink Ph.D., author of the forthcoming book, Slim by Design, Professor of Marketing and Director of the Cornell Food and Brand Lab.

The finding did not hold true with children. Analysis of 326 participants under 18 years old, showed that the average child eats only 59% of what he or she serves. “This might be because kids are less certain about whether they will like a particular food,” says Wansink. “Regardless, this is good news for parents who are frustrated that their kids don’t clean their plate. It appears few of them do.”
Wansink says that these findings, published in the International Journal of Obesity, can positively impact an individual’s eating behavior, “Just knowing that you’re likely to consume almost all of what you serve yourself can help you be more mindful of appropriate portion size.” Next time you grab that serving spoon, think to yourself, “How much do I want to eat?” and serve accordingly.
