<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 based on the idea that humans evolved eating foods that are similar to what our ancestors ate during the Paleolithic era, which was roughly 2.6 million years ago. This includes meat, fish, eggs, vegetables, and fruit, but excludes grains, dairy, legumes, and processed foods. Proponents say this type of diet can help people lose weight, improve digestion, and reduce inflammation.
