Food is one thing that has evolved massively throughout the last few generations . We transitioned from a diet based in meat, veggies and some fruits to a wide variety of processed food-like substances with artificial flavours and poor nutrient density. Our bodies were developed in adversity. Everyday was a battle to survive and because of that we developed different strategies or tools to stay alive. If it was too cold we would cover our bodies with animal skins or make fire to cook and warm-up ourselves. The seek for pleasure wasn't something free but a strategy to overcome the adversities that we faced daily.
