1. New study on the topics of mono-unsaturated and saturated versus polyunsaturated fats:
"Lipidomics of Familial Longevity.", by Gonzalez-Covarrubias V, et al.
Aging Cell. 2013 Mar 2. doi: 10.1111/acel.12064. [Epub ahead of print]
Quote:
In addition, the longevity-associated lipid profile was characterized by a higher ratio of monounsaturated (MUFA) over polyunsaturated (PUFA) lipid species suggesting that female offspring have a plasma lipidome less prone to oxidative stress. Ether PC and SM species were identified as novel longevity markers in females, independent of total triglycerides levels. Several longevity-associated lipids correlated with a lower risk of hypertension and diabetes in the Leiden Longevity Study cohort.
2. Longevity marker = MUFA/PUFA ratio in cellullar membranes:
"Fatty acid profile of erythrocyte membranes as possible biomarker of longevity.", Puca AA, et al., Rejuvenation Res. 2008 Feb;11(1):63-72.
Quote:
Erythrocyte membranes from nonagenarian offspring had significantly higher content of C16:1 n-7, trans C18:1 n-9,[mono-unsaturated] and total trans-fatty acids, and reduced content of C18:2 n-6 and C20:4 n-6 [polyunsaturated fats].

More Animal Fat & Less Seed Oils = Longevity!
Stan the Heretic has the details:

Comments are most welcome! But please:
- No SPAM whatsoever, no supplements, no pharmaceuticals, no herbs or any other advertisements
- Absolutely no quack-doctors pushing their quack-BS websites (and if you are a quack, I will call you out)
- Be critical if you want to, but try to be coherent
Comments are moderated, because I am tired of Gerwyn-V99-The-Idiot and his moronic sockpuppets, and tired of the story of the two dogs, but I will try to publish everything else.
If you are not Gerwyn (and want to tell me something other than the story of the two dogs), then relax and write something! :-)
