Re: Re: Report on Harvard's Healthy Aging Conference - opinions welcome

[Guest guest]

I agree. (In fact I had doubts about letting this post through to the board for that very reason).

IMO, FWIW, the “fountain of youth” does not yet exist. However I do enjoy 1-2 glasses of red wine a day, which I enjoy anyway, Vit D, and fish oil. I’ve stopped taking other supplements. All hype and not much different than the snake oil of previous generations.

I justify the wine because of the study posted by Rod I believe, that the men who drank wine lived longer than others. Of course there’s also the study that people who ate chicken and fish had an edge as well, over meat eaters and vegetarians.

I have recently read that 80% of longevity is due to genetics and the rest can be influenced by lifestyle. As far as supplements, I think that Vitamin D may give you more longevity for your dollar than resveratrol.

Of course, everybody slants their predictions and science to fit their desires, not humanity's. Drug company execs want humanity to wait for their drug, and researchers would rather the fountain of youth be discovered after they have retired so as to ensure they will have a lifetime of research grants.

Only mice engorged with a high-fat (60% fat calories) lived a bit longer when given resveratrol, and high-dose resveratrol actually shortened the life of lab animals on a standard-calorie (25% fat calories) diet. In a human study, all that 5000 mg of Sirtris Pharmaceuticals highly touted SRT501 resveratrol drug could do was modestly reduce blood sugar levels two hours after ingestion of a meal.

> de Grey touts the mitochondrial theory of aging, which cannot be denied and which he was not the first to describe, but fails to recognize experiments done in animal labs years ago already demonstrated how to reverse biological aging using metal chelators to eradicate lipofuscin, the cellular debris that progressively accumulates in living cells.

Such an intervention reinvigorates the cell cleansing mechanism of autophagy (lysosomal bodies within living cells literally cannibalize cellular garbage), thus restoring a youthful state to the cell.

This proof-of-principle study suggests a day in the not too distant future when humans can determine their biological age and utilize mineral-chelators to reverse the clock-hands of biological time.

To this end, technologies which promote youthful production of hyaluronan, the body's water-holding gel that insulates nerves, cushions joints, moistures skin, and serves as a scaffolding for the body, will have to be addressed.

I have recently read that 80% of longevity is due to genetics and the

rest can be influenced by lifestyle. As far as supplements, I think that

Vitamin D may give you more longevity for your dollar than

resveratrol.

The current Longevinex capsules have many-bottles worth of

red-wine-extract materials in them beyond the guaranteed levels of the

less-certain resveratrol, which is really a less significant element in

them, in my opinion. I've been taking one with a glass of red wine each

night for more than four years to get the red-wine stuff without the

calories. Similarly, I've been on 5000 (now 6000) IU of D3 daily for at

least three years, 1-2 g of C for 25 years, 6 g daily of high-omega-3

fish oil for many years, acetyl-l-carnitine for more than five years,

etc.

Together with our primary interest--caloric restriction--some of these

might be genuinely useful. D3 has the strongest demonstrated basis, I

think, so far, followed by the omega-3 fish oil and red-wine gunk and

aceyl-l-carnitine all sort of in the same tie area. There seem to be no

downsides associated with any of these products, in any case, so it

becomes a simple cost/potential benefit analysis for us.

Doesn't cost much for these items--the Longevinex stuff comes in under a

dollar a day--and their product continues to improve without increases in

cost. I'd quietly suggest that visiting their website and checking out

this, shock-horror, commercial product might be worth the few minutes for

our people. What I don't want to do is find, 15 years down the line, that

something that I could have been taking and that was recommended to me

really could have been beneficial, but that for some kind of not fully

dispassionate reason I eschewed taking it. Just because something is a

commercial product doesn't mean that you're going to get

" taken " by buying it, I figure.

We've all seen (Vit E) supplement hopes/claims come and go, but that

doesn't mean that some things might be worth adding in to the basic CR

plan that we all accept. As our multiple one-mouse experiments proceed, I

think more and more will be revealed.
