Recent research suggests that aging as we know it may not be
inevitable. We know that some animals do not seem to age such as
many cold-water ocean fish, some amphibians and the American
lobster continue to grow bigger, are able to reproduce and to
live until something kills them. Some people believe that
because of the animals that do not seem to age that it could be
something in their genes, and possibly in our genes, that
controls the pace of aging, and that aging is not the fate of
every living thing.
Scientists have discovered that when animals are forced to live
on 30 to 40 percent fewer calories than they would normally eat,
they become resistant to most age-related diseases that include:
•Cancer
•Heart disease
•Diabetes
•Alzheimers
And they also live 30 to 50 percent longer. Judging from the
animal studies, calorie restriction slows aging.
How this is, noone knows for sure, nor why aging occurs and
what are the underlying genes that preserve vitality and stave
off disease.
Few of us humans are capable of restricting our diets by 30 to
40 percent without being constantly hungry. So some scientists
began to look for ways to trigger the sirtuin system in action
without restricting calories. In 2003, a handful of
sirtuin-activating compounds were discovered. Resveratrol – a
molecule produced in plants such as red-wine grapes was the most
potent.
Resveratrol and other STACs have enhanced the vitality and
extended the life span of every species they have been fed to
such as:
•Yeast
•Fruit flies
•Worms
•Fish
The maximum life span of the fish increased 59 percent, which
is equivalent to a human living to 194 years. These results are
remarkable; however, it is unclear if resveratrol works in the
same manner in warm-blooded furry animals.
In studies with mice it was found that resveratrol:
•Reduced the risk of death by 30 percent
•The mice treated with resveratrol were leaner and developed a
greatly enhanced aerobic capacity
•Their muscles were consuming oxygen more efficiently
•Had greater capacity to generate energy
•The mice could run twice as far without getting tired
•At least for mice, resveratrol was found to be an outstanding
performance-enhancing drug
Evidence also indicates that resveratrol may protect against
aging-related diseases. In studies around the world, resveratrol
protected mice against:
•Heart disease
•Cancer
•Diabetes
•Alzheimer's disease
These are the very diseases that reduce most people's life
span. The question of what this all means for humans is still
unanswered, yet, could be just as beneficial. Things that are
true in mice are often, but not always, true in humans.
Researchers plan many more studies in both animals and in
humans in 2007. Some of the first human studies of resveratrol
will tell us whether it can help people with either type 2
diabetes or a rare condition called MELAS syndrome that causes
brain and muscle destruction in children.
Other good news is that research has started now to find
sirtuin activators that have the same effects as resveratrol,
but are more potent.
Resveratrol is found in red wine and because of this some
people are asking whether they should drink more red wine, or
drink red wine to the exclusion of other alcoholic beverages. I
personally tried drinking a 6 ounce glass of red wine each night
before I went to bed, and felt quite horrible the next day. I do
not drink alcohol at all, but was trying this for myself because
of all the news I read about the heart health benefits in red
wine. I have abandoned the red wine for 10 fluid ounces of 100%
grape juice. Most scientific researchers tell us there is not
enough resveratrol in red wine to make it a good idea to start
drinking it for our health.
Resveratrol tablets and capsules are also available over the
counter, but they are of no "proven" value in humans, and they
are not manufactured and controlled by the Food and Drug
Administration.
Animals that have been given resveratrol treatment are
remarkably vital until the end. The studies in animals seem
promising. In the future we may be taking resveratrol
supplements right along with our daily multivitamins. As of
today, however, according to scientific proof, it is still
better not to start drinking red wine if you are a non-alcoholic
drinker to begin with in the hopes of prolonging your life or
having better health. We are probably still safer drinking our
100% grape juice until further studies prove resveratrol in red
wine is worth drinking an alcoholic beverage.
