Jerky was originally a survival food, and a hell of a lot better for looks than starving to death. But obviously the people who made it preferred fresh food when they could get it. According to the wikipedia article on jerky (charqui) the stuff the stupid article is talking about has very little to do with the early-human survival food technology. en.wikipedia.org/wiki/Jerky_(food) I'd think the original would take a lot of chewing, and one would be unlikely to overeat it.
My sister and I were driving endlessly through Texas (actually, the only way you can drive through Texas) and stopped at a roadside shack to buy real, homemade style jerky. Omygod -- if you're any kind of a meat eater at all, the stuff is addictive, really insanely good.
Apparent basics of the thing are that grass-fed critters are better for us because they have more omega-3 and less omega-6 and because Paleolithic Era people ate grass-fed critters and - so they claim - no grains, this is the more natural diet of humans. I'm not sure I want to base my nutrition on Paleolithic Era man, although the stuff about omegas sounds sort of plausible. There is mention of other studies finding different numbers, not sure how the samplings might have differed to cause that as I've not read up on the other studies.
I don't know the lifespan of paleolithic humans but I would think they would be shorter than ours. I've read conflicting stories about the lifespan, which depended on whether someone was selling the Paleo Diet or now.
At any rate, I would think modern people live longer, due to a number of factors such as clean water and medical advances. These longer lives may not be quality but that is a topic for another day.
I just found this thread and read this list............they say whats bad for you but I notice they dont list the food that make you beautiful..............perhaps there is none left.............. I think my own diet is made up from this list and I aint ugly, a bit wrinkled perhaps, but not ugly....
