I guess we will have to agree to disagree, but I find it very hypocritical that you all are saying you have the right to parent your kids, not others. If you want your kid to have a cupcake at school, then send a cupcake with them. Just don't send one for mine. If you do, then I'll send him home with you for you to deal with the behaviors.
ETA: I never said that cupcakes caused obeisity, but that there are a host of other reasons than obesity not to send cupcakes and sweets to school for other kids--with the major reason being the one many people have quoted--it's not another persons' right to decide what's best for my child. And FWIW, when I take my children to bday parties, my son is allowed to have sweets, because I am there to 1. monitor the amount and 2. will take the responsibility for his actions later. A teacher with 20 other students in the class, however, should not have to deal with that.
From the American Journal of Psychiatry:
* "It is unlikely that sugar and aspartame are clinically significant
causes of disruptive behavior." (American Journal of Psychiatry:
"Effects of sugar and aspartame on aggression and activity in
children:" http://ajp.psychiatryonline.org/cgi/content/abstract/144/11/1487
There are plenty more studies that debunk the notion that sugar intake affects behavior.
