While I have been trying to change up my eating habits a bit and talking to patients about trying some new foods, I came upon an interesting study in the journal Pediatrics.  

The hypothesis for the study, which was done among school children in Philadelphia, was “can smaller plates promote age-appropriate portion sizes in children?”.

There have been previous studies in the adult literature that have shown that dish ware size influences self-serve portion sizes and caloric intake. Whether the same conclusions with children were true had yet to be examined, but it does make sense that it might.

So, the hypothesis was correct and when children were given larger bowls, plates and cups, they served themselves larger portions and in turn more calories. In the study, 80% of the children served themselves more calories at lunch when using adult-size plates and bowls.

This is really great news, in that by changing the size of the plate we might be able to affect a child’s portion size without them even really being aware!

I remember that our kids all had children’s bowls, plates and cups that they loved to use and eventually they either broke, got lost, or we just decided to have everyone eat off of the same plates. But, maybe it would make more sense to continue to have our children use child sized plates until they reach puberty?  Certainly seems that it wouldn’t hurt and if schools did the same thing we might be able to impact some of the obesity problem by just changing one behavior.  It is definitely worth trying!
