Is the number of generations our ancestors have been agriculturally active enough to have an evolutionary effect on how our bodies metabolize food? At most is seems it has been 14000 years, whereas we've been around for several hundreds of thousands of years. I don't know the answer there.

I suspect it's enough to have small effects but not enough for complex adaptations (requiring multiple mutations to stack). Actually, I think I read that adult lactose tolerance evolved during that time? I'd also guess that it's plenty of time for a lot of evolution to have gone on in our gut flora.

14,000 years is about 700 generations. That's not a little bit.
