Human: I've been hearing a lot of talk about a new diet called the Paleo diet. What is it? Assistant: 
The Paleo diet is a diet that focuses on foods that were available to humans during the Paleolithic era, which is the time period from 2.6 million years ago until 10,000 years ago. The goal of the diet is to mimic the diets of our ancestors and to reduce the risk of developing chronic diseases such as heart disease, cancer, and diabetes.
