The first and third links that Hannah cited are vegan propaganda, which Tyler pointed out regarding the third.
The first link is from Ross Horne, a vegan propagandist with a fruitarian tilt who died from prostate cancer (
http://www.vegsource.com/talk/raw/messages/12457.html). According to this article, Rawzi is correct that Horne's approach was similar to that of Viktoras Kulvinskas:
http://en.wikipedia.org/wiki/Fruitarianism. Incidentally, Viktoras Kulvinskas looks older than his age, not that that proves anything any more than Stefansson's anecdotal claim does:
Viktoras Kulvinskas, born 2/23/1939 (per
http://www.astrotheme.com/portraits/9eq5b67wE9rk.htm)
Kulvinskas was 70 years old at the time this image was posted in June of 2010 (his actual age might have been even younger in this image, if it was taken much before the date it was posted).
Compare to meat-loving Art De Vany at age 71 (again, I'm not saying that this proves anything, just highlighting the ridiculousness of the vegan propaganda):
The Stefansson link is somewhat more credible, but Tyler has pointed out in the past that Stefansson was not accurate about everything and there were many other adventurers and scientists whose reports on the Inuit differed somewhat from Stefansson's. Plus, it's telling that the vegan and vegetarian sources that cite this quote of Stefansson cherry pick it out and ignore all the many positive things he said about meat-based diets. For credible counter evidence, try googling on the terms "carnosine" and "anti-aging."
Even if the claims about Eskimo premature aging and short lifespans are true, it wouldn't necessarily mean that high protein intake was the source. Other possibilities include excessively high intake of n3--especially heated n3--the concentrating effects of white snow on sunlight exposure to the face, and inhalation of smoke from oil lamps and pipe smoking
, though smoke and concentrated sunlight might not explain the alleged difference in aging and lifespan between Inuit and other aboriginal peoples.
If anything, the images of the elders of the Great Plains
tend to appear more wrinkly and aged to me than those of Inuit elders, and there I suspect that sunlight is the biggest likely factor, with smoke and introduction of modern foods being other possible factors.
Hanna, are you eating an Eskimo-type diet? If not, what are you worrying yourself about it for? What was the source of the claim about Nenets aging prematurely (I hope it wasn't another vegan propaganda source)?
For those who want to eat a meat-heavy diet and reduce their risks, it may be wise to avoid overcooking, heating of n3's, and excessive smoke inhalation and to make sure to eat enough organs, raw and fermented foods, and/or seafoods, all of which the Eskimos tended to include in their diets (and even Stefansson acknowledged that the Eskimos he observed loved loche fish livers) to minimize potential negative effects from overcooking and smoke and to get sufficient important nutrients and probiotic microbiota.
I plead with people to please investigate your sources carefully before you post anti-meat and anti-RPD info like in this thread, as it can unnecessarily scare newbies and easily-frightened folks and then Tyler and others have to waste time calming them down again.
