Changes in diet over the last 100-200 years have resulted in narrower palates, weaker jawlines, more crowded teeth, and changes in facial shape due to less chewing.

“So take go back a hundred years, 200 years, a thousand years. We had to chew a lot more to really digest our food. We were working our massitors. We were working our jawline. Our pallets were not as high. Our jawline was a lot wider. Our teeth were stronger. And then as we have changed our diet and everything is cooked and we don't have to make as much effort to chew it, you actually get more crowding in your of your teeth. Your jawline is a little bit less strong. Your pallet changes.”

And that has been measured anthropologically.”
