Can thinking in these terms help us to address modern problems, from the obesity epidemic to anti-social behaviour or coping with climate change impacts?
The diet in paleolithic times included meat, nuts and berries. At the time, they adapted to the food that was available to them and this is what their metabolism is based on. It is said that modern humans are still best adapted to paleolithic diet
