I've been hearing a lot of buzz about a new diet craze called Paleo. What is Paleo?

Paleo is an eating style that focuses on foods that were available to our ancestors during the Paleolithic era, which lasted from 2.6 million years ago until 10,000 years ago. The idea behind it is that humans evolved to eat these kinds of foods and that they are best for health. It includes lots of meat, fish, eggs, vegetables, fruits, nuts, and seeds. It's also known as the "caveman" diet because people think cavemen ate this way.
