I think your comment raises a point that I haven't seen from others yet -- are girls much more prone to being really picky eaters? Your comment, and my personal observations, seem to say "yes." I wonder if this is related to later in life, when young women seem to be more prone to being vegetarian/vegan, and much more prone to eating disorders also.
Re#45 Good morning and good point. I have not researched it but I recall that a lot of the disorders girls have are based on physical appearance/esteem issues. That said, there may be a genetic/hormonic component too...
