I should start off by saying that I have no idea about the validity of what I'm about to say. It is 100% hearsay, with added conjecture on my part. I do not vouch for its authenticity in the lease, it was just something that has been bouncing around in my head for a week or so.
My wife is pregnant with our first child. During one of her regular visits to the Doc, they had a conversation about how much weight a woman should gain during pregnancy. The Doc gave her a review of the past few decades of baby having. From this conversation (this is the hearsay, the conjecture comes later) I gathered that in the 70's women were discouraged from gaining much weight during pregnancy, and as a result, there were some health problems, including low birth-weight babies. So Doctors shifted gears in the 80's-90s, and went with a Doritos style advice "Eat all you want, we'll make more" "And the result was fat babies. So I'm wondering what carry over effect, if any, children get from their mothers consumption habits during pregnancy? Could this be a factor in the giant children problem in this country? In my opinion the ultimate responsibility lies with the parents, but I wonder how much biology might play in this.
Of course, others might talk about the convinience of fast food, and an increase in two income families as a contributing factor. I don't think that McDonalds will have a problem overcoming this lawsuite, given the number of variables involved, but who knows?
