Experts
Call Anti-Aging Products a Waste of Money
Not
only do they not work, but also some are harmful to your health
Anti-aging
products that promise to turn back the clock do not deliver and may
even be hazardous to your health, says a renowned team of scientists.
"Don't
waste your money on anti-aging products," says S. Jay Olshansky, a professor
in the School of Public Health at the University of Illinois at Chicago
and a senior research scientist at the university's Center on Aging.
Olshansky
and 50 of his colleagues, all top researchers in the field of human
aging, recently drafted a position statement on the subject. In it,
they warn consumers that anti-aging products (such as growth hormone
and antioxidant supplements) and promises of longer and longer life
spans via such measures as caloric restriction are not proven to work
for humans. Olshansky also co-wrote an essay on the topic that accompanies
the position paper in the June issue of Scientific American.
Not
unexpectedly, the paper drew fire from one of the leading proponents
of anti-aging medicine, who calls it a "100 percent political" attempt
by traditional physicians to wrest control of a growing industry.
In
the paper and the essay, the scientists tackle a wide range of products,
but in an interview Olshansky singled out human growth hormone, melatonin,
and dehydroepiandrosterone (better known as DHEA) as specific products
to avoid. Some anti-aging proponents contend that replacing these hormones
as their levels dwindle with age can keep people young.
Some Anti-Aging
Products May Prove to Be Harmful
Not
only do these products not deliver what they tout, Olshansky says, but
"some of these products are likely to be dangerous. In animal models,
animals given growth hormone have shorter life spans. Short-term, the
animals appear younger, but they die sooner."
Likewise,
he adds, nutritional supplements rich in antioxidant vitamins E and
C that purport to soak up free radicals, those renegade molecules that
damage cells and tissues, are not proven. The vast majority of studies
showing that antioxidant intake is valuable for reducing the risk of
cancer and other ailments have been done with foods, not vitamins, Olshansky
says.
In
the essay, he and his two co-authors further state that "no one has
established that vitamin supplements containing antioxidants limit oxidative
damage in the body or influence aging."
While
the public is bombarded with misleading anti-aging claims, Olshansky
and his colleagues say, serious biologists are studying the underlying
nature of aging to determine how to slow it down, improve the quality
of life, and ward off disease.
"No
product currently sold [for that purpose] has been demonstrated to reverse
aging," Olshansky says.
Some areas under study, including caloric restriction and genetic manipulation,
are viewed by the authors as worthy of more research.
The
essay and the position paper have clearly outraged one of the more outspoken
advocates of anti-aging medicine.
Dr.
Ronald Klatz is president of the American Academy
of Anti-Aging Medicine in Chicago, and he posts studies on
his Web site finding favorable effects for growth hormone and the use
of megavitamins to fight disease.
"How
can you be against anti-aging medicine?" asks Klatz, who says he plans
to submit a rebuttal to Scientific American. The decision
to publish the position paper, he says, "is 100 percent political. It's
all about who will control a trillion-dollar industry."
He
defines anti-aging medicine as "any intervention or modality that has
to do with the early detection, prevention, treatment, or reversal of
age-related diseases. We don't promise to reverse aging."
While
critics focus on anti-aging products, Klatz says anti-aging medicine
is much more than that. It is committed to health promotion and advocates
nutrition monitoring, managing risk factors for disease, and disease
screenings. According to Klatz, more than 10,000 physicians and scientists
worldwide belong to his academy, and anti-aging medicine has matured
into a prestigious medical field.
The
only common ground Olshansky and Klatz seem to share is promotion of
a healthy lifestyle that includes regular exercise and a sound diet.
Looking for the Fountain
of Youth
"If
there is a Fountain of Youth—and by the way, there isn't—the closest
you can come is exercise and, of course, a good diet," Olshansky says.
"Exercise has been shown to reduce blood pressure, increase muscle mass,
reduce body fat, improve mental acuity, and improve skin elasticity."
If you are wondering how to spend the money you now spend on anti-aging
products, Olshansky has a few suggestions. "Arrange a meeting with a
registered dietitian. Buy a good pair of walking shoes. And get a massage."

Exercise
Keeps the Elderly Strong and Independent
It
is no surprise that whatever your age, exercise is good for you.
But
a new study's results should be encouraging news to older folks:
Exercising just once a week may be enough to allow you to stay
on your own and remain independent.
According
to researchers from Ball State University in Muncie, Ind., older
adults need to exercise only one day a week to maintain their
muscle strength, allowing them to avoid injuries and remain independent.
Low-volume,
high-intensity resistance training can counter the decline in
muscle strength and size commonly associated with aging that can
lead to falls, say the researchers.
In
this study, 10 men all over age 70 did resistance training three
days a week for three months. They were then divided into two
groups of five men: one that continued the exercise, one that
stopped.
Six
months later, the five who stopped regular physical activity had
a significant decline in muscle size and strength. But those who
continued resistance training once a week maintained the strength
they had developed in the initial training session.
The
study was published in a recent issue of the Journal of
Gerontology: Biological Sciences.
