The Paleo diet, known for its emphasis on lean meats, fruits, vegetables, nuts, and seeds, has long been promoted as a way to eat like our prehistoric ancestors.

Published in the Proceedings of the National Academy of Sciences, the study supports the idea that ancient humans relied heavily on plant-based foods.
