This book has actionable information on how to get started in the paleo diet. 

Humans got creative with food, and then the problem set in. Nature already provided us with all the foods we would need until the end of time. Even today, there are thousands of crops, fruits, sweeteners, and condiments. These natural foods provided by nature are what our bodies are designed to process. But somehow, we were not satisfied. We decided to experiment a little, so we started cooking our foods and adding a little of this and that to create a more thrilling experience. We completely forgot that food wasn’t a source of recreation and its only purpose is to provide the nutrients that our bodies need to function.

Eventually, in a bid to make money, some people discovered the art of processing and packaging food and selling it to people. But they also got greedy. In order to expand profits and create new products, they learned how to add some chemicals to the foods to make them sweeter, double up food quantities, or get people addicted to their products. Soon enough, our feeding patterns deviated a lot from what was natural and what our bodies were designed to process. Our foods became very artificial, and many of the preservatives and additives started poisoning our bodies. Some researchers and nutritionists, after conducting several studies, discovered that the only way to save the human race from many of these new age diseases, which are mostly triggered by our diets, is to have us return to a natural diet - the one our bodies were designed to handle. The paleolithic diet is a diet that requires you to eat like the paleolithic humans, our ancestors who lived during the Stone Age.
