The most important thing about the Paleo diet is to remove anything that is processed and refined. This means no dairy products, grains, bread, sugars, legumes, processed oils, salt, alcohol, and coffee. That might sound like an awful lot of things to be removed from your diet, but you are still left with a lot of choices when it comes to fresh, unprocessed ingredients. On the Paleo diet, you will be able to eat meat, seafood, vegetables, fruits, nuts, and roots.
