<human>: I've been hearing a lot of talk about a new diet called the Paleo diet. What is it?
<bot>: The Paleo diet is an eating plan 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. This includes meat, fish, eggs, vegetables, fruits, nuts and seeds, roots, and some dairy products. The diet is based on the idea that humans evolved to eat these types of foods, so we should eat them too.
