It probably does, must fruits and veggies that we know of didn't exist ~500 years ago. All modern fruits are sugar bombs compared to "old" fruits. Old fruits were more bitter and much smaller.

And destroyed teeth are only the most visible side effect, god knows what else is happening to our bodies.
