So I don't see why it's surprising that popular children's toys would represent sort of the platonic ideal of the human form. In reality most people's calves and hips do flare out to some extent, so it makes sense that those sorts of features would be accentuated when reduced to toy form.
> And they get fed foods with super exaggerated flavor profiles, e.g. ketchup
What? Since when is ketchup a kids food? That's a pretty widely popular condiment among all ages.
That is a myth. The truth is fairly complex but boils down to that one agency briefly proposed adopting rules that might if adopted have allowed things like pickle relish to "count as a vegetable" in certain contexts.
Ketchup was not explicitly listed in the proposed rule and the rule never took effect so we'll never know how local authorities might have used that bit of new flexibility.
TL;DR: Ketchup has never counted as a vegetable. (Salsa, on the other hand...)

This holds true for male dolls too. I saw a great interview with Mark Hamel once about the evolution of Luke Skywalker dolls, which are now more WWE than a realistic portrayal of his character.
Look at the animation in Archer. Lana and Archer both have thick eyebrows, but Archer doesn't have any eyelashes.
Would clothes fall off a Barbie doll if you flipped it upside down? Do they fall off of Ken? I find that argument highly questionable.

In some senses, yes, we do. Children often like brightly colored clothes (and objects in general), or clothes with large, obvious representations of things they like.
Foods with strong uncomplicated flavor profiles also go over well. Mac & Cheese, Chicken tenders, etc.
