Through my research I stumbled across the website Paleo Australia, which provided me with the answer to my question.
What the *bleep* is paleo?
‘Paleo’ as a word simply means ‘old’ and refers to the way we as a species were living in our days of hunting and gathering. Living a modern paleo lifestyle doesn’t mean you should move into a cave and hunt down your neighbours cows with a spear. It simply means looking back to what we as a species have evolved to eat, in order to achieve optimal health.
