How Long Shall Humans Live? The Current Answer Is
Found in a Glass of Red Wine

As
I entered the Harvard laboratory, it was inauspicious. The myriads
of glass flasks and laboratory work benches were arranged in a haphazard
fashion. One wonders what could come out of all this biochemical
chaos? But this lab has gained unusual attention in the past few
weeks, and its discoveries are sure to affect the future of mankind.

David
Sinclair, PhD, Harvard genetic scientist has
found how to turn a survival gene into a longevity factor. |
The
laboratory I am talking about is the Sinclair Lab, named after Dr.
David Sinclair, a pathology professor at Harvard Medical School.
David
Sinclair is a young, smiling, bio-genetic researcher whose passion
has been the study of aging. A native of Australia, he came to the
USA to do research work at MIT and Harvard noticed his accomplishments
and lured him with his own laboratory, now housed in Goldensen Building
at Harvard Medical School.
Up
till now, the only unequivocal method of prolonging life has been
calorie restriction. The prospect of a near-starvation diet is obviously
a difficult idea to market to human populations. So the announcement
of Sinclair's research is being met with glee.
Sinclair
has been interviewed by every major news network in recent weeks
for his discovery, published in Nature magazine, that a dietary
component could lengthen the human life span by 70 percent, up to
50 years. A 125-year human lifespan could become common! Even an
older adult could live years longer by increasing dietary resveratrol
intake.
A
survival gene becomes a longevity factor
What
Sinclair and his students have uncovered is a survival gene that
can be "switched on" to become a longevity gene. The gene increases
the production of an enzyme that prolongs the time a living cell
has to repair its DNA genetic material. This enzyme is normally
produced when the survival of living cells is threatened by starvation,
exposure to germs or bombardment by solar ultraviolet radiation.
No longer would humans have to starve themselves to prolong life.
In
a plant model, the skin of a grape increases its production of the
enzyme which produces a protective molecule called resveratrol.
It is resveratrol, when given to yeast cells, fruit flies, worms
and mice that extends life by a whopping 70 percent. Humans have
the similar survival gene.

Pinot
noir grapes contain more of a newly found longevity factor
than other types of grapes. |
There
has been a flurry of scientific reports on resveratrol recently.
About 450 of the approximately 750 scientific reports on resveratrol
listed by the National Library of Medicine have been published in
the past 24 months. Studies point to this miraculous molecule as
a potential cure for cancer, heart disease, age-related brain disorders,
and much more. Resveratrol inhibits fungal infection, raises HDL
"good" cholesterol, lowers PSA levels in males, raises immunity,
controls blood pressure, preserves red blood cells, prevents blood
clots and inhibits inflammation. How much more could one ask of
one molecule? Furthermore, it would take only about 3 to 5 milligrams
of resveratrol, about the amount provided in a glass of red wine,
to produce these results in humans.
The
future of resveratrol
During
my two-hour interview with Dr. Sinclair, I asked him what he had
in mind for the future of this molecule. He said that venture capitalists
had the idea of taking artificial copies of resveratrol, called
analogs, and making them expensive drugs. But they were disappointed
when his laboratory disclosed that the same molecule could be acquired
in a glass of red wine. A resveratrol drug would probably take a
decade to develop and get approved by the Food & Drug Administration,
added Sinclair.
Dr.
Sinclair says the public needs to know more about this remarkable
natural molecule and how to get more of it into their diet. It could
be as simple as drinking a 5-ounce glass of red wine, preferably
from pinot noir grapes grown in northern latitudes like New York,
Oregon and Washington, that generally yield more resveratrol than
other varieties.
Challenging
resveratrol
Of
course, Sinclair's research is so unbelievable that it required
some further challenges. Why aren't everyday imbibers of red wine
centenarians? Why can't people just drink grape juice, or eat raisins,
or grapes for that matter, and live longer? The answer lies in the
wine-making process. The fermentation process extracts resveratrol
from the skin of a red or purple grape and then it is kept from
spoilage in a nitrogen-flushed bottle. The air doesn't get to the
resveratrol in a bottle of wine so it can't oxidize. Grape skins
provide resveratrol, but not in an extracted form. Due to processing,
grape juice provides little resveratrol. Sun-dried raisins also
contain no resveratrol due to oxidation by sun rays. The same is
true for resveratrol pills which are widely marketed. Their resveratrol
content, extracted from the Giant Knotweed plant (also called fo-ti
in Asian cultures) for use in dietary supplements, is nil. Sinclair
has tested a number of brands of resveratrol pills and their resveratrol
content was zero. The resveratrol disappears soon after exposure
to air during encapsulation. For now, red wine is the only reliable
source of resveratrol. White wine has ten times less resveratrol.

| Pinot
Noir red wines from northern climates, such as this wine from
New York, yield greater amounts of resveratrol, now identified
as a life-extending molecule. Wine prevents oxidation of resveratrol
whereas this molecule is destroyed in currently-produced dietary
supplements. |
What
will humanity do?
What
will humanity do with a molecule that can repair damaged DNA, abolish
age-related disease as we know it and prolong human life by decades?
Who will pay the Social Security payments up to age 125? How will
insurance companies re-calculate actuary tables? Can you get a refund
on your long-term care (nursing home) insurance if you don't need
it? After all, a great deal of planning goes into the assumption
human beings will die on time, in their seventh or eight decade.
Dr.
Sinclair says the world will need to adjust accordingly to discoveries
such as resveratrol. This kind of discovery can't be hidden. Just
imagine, Sinclair said, what people could have said after Alexander
Fleming announced his discovery of penicillin in 1922. At the time,
nay-sayers could have claimed that penicillin would eradicate infectious
diseases and dramatically expand human populations, resulting in
famine and war. Why not let the concept of "survival of the fittest"
reign?
Thomas
Malthus issued his doomsday theory on population growth in 1798
which meant any dramatic increase in survival would doom humanity
to overpopulation, scarcity of food, and eventual massive trimming
of the size of the world's human populations. But Malthus couldn't
foresee the industrial revolution or modern methods of crop production.
Similarly, the availability of a stabilized resveratrol plant extract,
now underway, could also be used to increase human food supplies.
For example, dipping apples in resveratrol preserves their freshness
for weeks following harvesting. Resveratrol may have use as a novel
food preservative, thus remedying a social problem of its own creation.
The
word resveratrol is soon to become widely known. Millions will benefit
from its availability. The introduction of a non-alcohol dietary
supplement that can reliably deliver standardized amounts of resveratrol
to human populations would certainly cause a stir throughout the
world. No date has been given in regards to the introduction of
such a product, but it is reported to be beyond the drawing board
stage. Dr. Sinclair is the genie who is unleashing this molecule
and future reports on his work will only substantiate what has already
been documented.
