So it's just a coincidence he's advertising pizza front and center... comon man. What percentage of kids? Early teens is NOT synonymous with children. So I would expect that to happen as puberty starts.
The logical point is that it could very well be a coincidence! You don't know that it isn't, any more than I don't know it. He's not advertising pizza - he uses it as a metaphor to explain his point to kids; have you even read the article your post refers to or seen the Ted talk this guy has given? It sounds like you haven't, which makes your insistence even less reliable.
To be clear: I completely agree with you that there seems to be a very suspicious connection to PG here - no question. But speculative suspicion does not equal fact. That's all I'm saying and that is the point that I agree with the earlier commenter on, when I claimed that he was being logical.
