They did a couple other "kids and food" things, as well. One experiment showed that kids will NOT necessarily stop eating when they're full (the kids in the study weren't from CL families, which I'm sure has an effect)... BUT that was when someone else was doling out portions, and they concluded that *if you allow the child to serve themselves* they generally will get very close to the exact appropriate serving size.
Another one was the sugar-makes-kids-hyper idea, and of course that was shown to be a clear myth. Sugar may not be good for us, but it doesn't cause hyperactivity. The kids were calmer and more focused on the day they had tons of sugar (I mean, these kids were turned loose on sweets, and were putting sugar cubes in Sprite!) The way the experiment was set up in the show (and as I said, these were fairly informal - more for illustrative than scientific purposes)... the parents
thought the kids got non-sugar food at the first party, where they actually got as much sugar as they wanted, and the next day they thought they were getting the sugar when in reality they had only sugar-free food. So the parental expectation could have played in that outcome.
Also at the first (sugary) party they had arts and crafts and calmly led activities... at the second (sugar-free) party they had this magician guy who was REALLY exciting and enthusiastic, and by the time he got the kids all riled up they were falling down, running around, and throwing food. I think the implication was that the overstimulation had more to do with it than the sugar.
Just very interesting, some things are taken as "proven fact" - such as the sugar=hyperactivity connection - when in fact they are not proven at all. And yet the ideas persist.
