Advances in food production means that the proportion of people starving and undernourished is lower than ever. It also means that, for the first time, excess food is a problem for more than just kings. It would be kind of crazy to complain that these advances in food production are per se a bad thing because they enabled obesity. They're just a tool that accelerate both good and bad uses.
It was already possible to feed the idle, addiction-prone part of your mind with channel-surfing and People magazine. The Internet has accelerated this possibility by making everything about access to content more efficient, but describing efficiency solely as "making access to bad stuff" more efficient makes no sense.
To me it seems similar to blaming an advance in fuel efficiency for making it cheaper for bank robbers to get to their targets. It's true, but also missing the point.
