The modern term Paleo, derived from Paleolithc, describes an era before modernization. In our current culture it most often refers to diet and how food processing has changed the delivery and consumption of food. Since we cannot adapt as fast as food production has changed, the consequesnces show up as large portions of the popluation with types of illnesses and diseases that were relatively rare just a few thousand of years ago.
Daniel Lieberman has an interesting book that explores this subject – http://amzn.to/28ZEKXe
Discover magazine had an interview with Dr. Lieberman which covers the main topics of the book and forces us to look at our habits and wonder if our modern lifestyle is leading us to poor health – http://discovermagazine.com/2015/may/16-days-of-dysevolution
What about a Paleo Spine, or a Paleo Lifestyle that goes beyond diet?
From antropological research it appears our peleolithic anscetors ambled across the earth covering from 5-10 miles every day. They hunted, tracked game, dug for roots, foraged, and more. Most likely they were in motion a large portion of their day, just to survive.
With all that movement, their bodies looked different from modern humans. http://www.npr.org/sections/goatsandsoda/2015/06/08/412314701/lost-posture-why-indigenous-cultures-dont-have-back-pain
How can we use this information to our benefit? We can move more, do a wider variety of movements, walk more, run more. The end result will be a stronger body and a stronger spine, and possibly a dissappearance of modern diseases.
