Hmmm. It's also a process of blind optimization on the part of companies that sell food. If they stumble into things that are addictive, that short-circuit the reward function in human appetite functions, they make more profit. Industrialization, marketing, high quality feedback mechanisms - they all add up to exploiting the human choice function.

Yes, industrialization of food is a function of culture. It's a tough one to fight against though, because marketing is also a culture generator; it needs constant oppositional effort.
