Mostly because our solution for it was to evolve based on the foods we foraged, which tended to provide the right balance of nutrients to keep things moving smoothly. Agriculture disrupted that, but that disruption hasn't been enough to have an appreciable impact on reproductive success, so we haven't had any pressure to evolve around it (that, and the food that's available to most human populations is changing far more rapidly than evolution could possibly keep up with).

Now that I think about it:
How do we know that? Is that just speculation of "old times were better because we were built for it", or because there's some actual poop archaeology happening?
