A better diet is making us taller. There are plenty of post-WW2 Japanese and Koreans that are quite tall thanks to McDonalds and such.

"A better diet is making us taller."

I remember from a couple of decades ago that there was some buzz that hunter-gatherers had been tall, then people shrunk as a result of agriculture limiting their diet, and now we're regaining the lost height.

I didn't say that a better diet is making us taller. I just said that a different diet is having that effect. Considering the obesity and heart issues so prevalent today that didn't exist 100 years ago, I seriously doubt that we have a better diet today.
