Humans have come a long way in terms of most things be it medical science language space exploration or even food options. However believers of the Paleo diet think that all the progress made in terms of food isn't desirable and we should go back to eating like our ancestors did thousands of years ago. Commonly referred to as the 'caveman diet' paleo diet consists of food products that were available back in the days when cavemen used to live. Followers give up all forms of processed food that is usually unhealthy along with all forms of legumes and grains.
