ASPIRIN, HORMONES AND OTHERS
The Vit-Min-Herb industry
has more to sell than vitamins, minerals and herbs. They are
always on the lookout for a new substance that has a smidgen
of medical credibility and then pump it up into a new
glamorous product to make you think you will feel better,
live longer but will also make you a tad poorer.
Unfortunately for them, aspirin is not one of them but DHEA,
melatonin and pycnogenol are.
Aspirin
This is an incredible chemical with many useful benefits in the
medical field. It is a true herb, originally coming from the bark of
the white willow tree. Of course, it is an analgesic, a pain killer.
In addition, even in small doses it coats the platelet cells in blood
rendering them less likely to clot. It has been used for years by heart
patients to prevent clots from forming on known cholesterol plaques
in the heart arteries. It also can prevent heart attacks in otherwise
healthy people. In a large, very well conducted study, 25,000 doctors
took an aspirin tablet one day and a beta carotene capsule the next.
Surprisingly and much to the chagrin of the Vit-Min-Herb industry, beta
carotene, the highly touted anti-oxidant, was ineffective in preventing
cancer. In fact, it seemed to increase the chance of lung cancer in
cigarette smokers. On the other hand, those physicians taking an aspirin
tablet every other day had half the heart attacks as those who did not.
Several caveats. First, physicians as a group live much longer and have
fewer heart attacks than the general population, so the benefit
may not be typical for the average person, whoever that is. Second,
there were very few females and African-Americans in the group, so we
must be cautious in predicting the benefit to others. Still, the evidence
for the protective effect of aspirin is so good that it makes sense
for some, especially middle aged males, perhaps who are borderline overweight
with a slightly high cholesterol and/or blood pressure, to take an aspirin
each day. If you are a thin female with a cholesterol below 200 and
a high HDL, the good cholesterol, it probably doesn't help since you
are already so cardio-protected. Further, the very slight risk of a hemorrhagic stroke may outweigh any benefit. Caution - Always clear this
action with your physician. If you have a history of peptic ulcers or
a bleeding problem, aspirin may not be for you. I recommend the 81 mg,
low dose aspirin each day. If you have the patience, you can get a pill
splitter and split a regular aspirin tablet into quarters which is 81
mg each -- less than 1¢ a dose! Every 15 days take a whole 325
mg aspirin to keep your blood level at the proper amount.
Melatonin
This is an incredible story. To understand it, you must first know
what a hormone and a gland are. A gland is an organ in the body that
makes a protein called a hormone. The hormone, in turn, has an action
somewhere else in the body. There are dozens upon dozens of glands in
the body, each making its own genetically controlled hormone. The ones
most people know about are the thyroid, (thyroid hormone), adrenal (cortisone,
adrenaline), ovaries (estrogen), testes (testosterone) and pituitary,
the master gland at the base of the brain which orchestrates many of
these other glands, again through hormones. All the body's glands and
hormones work together to produce an incredibly complex system called
normal human physiology - a true Michelangelo, nay, a godly masterpiece.
The pineal at the base of the brain is also a gland and it makes melatonin,
a typical body hormone. Scientists don't know a whole lot about it.
It may have a role in regulating blood vessels, the ovaries, the gastrointestinal
system and even the brain. It appears to be released in the evening
and some think it gets the body ready for sleep.
Melatonin has been claimed by the Vit-Min-Herb industry to vanquish
insomnia, jet lag, impotence and reduced libido, slow the aging process,
prevent cancer and, of course, much more. Naturally, there is very little
scientific evidence to support any of these claims. Is it good for sleep?
It is probably better to drink a glass of warm milk or take an over-the-counter
antihistamine.
The incredible aspect of the melatonin story is how the Vit-Min-Herb
industry got its hands on a hormone in the first place. Except for DHEA
(see below) they do not sell any other hormone. I am reminded
of the stories of thyroid hormone sold over-the-counter to overweight
people in the 1930s so they could "burn" off weight. It caused a hypermetabolic
condition called hyperthyroidism which made lots of people sick and
killed some. But there is melatonin sitting on the health food store shelf waiting
for you to buy it. Would you buy and take thyroid, adrenal, estrogen
or testosterone hormones on your own without good medical advice? Yet,
the Vit-Min-Herb industry has convinced many of melatonin's value. The
value is only in the industries' bank account. They claim it as a dietary
supplement. It is not. Further, you have the same unregulated unknowns
regarding dosage, sterility and safety that pervades the entire Vit-Min-Herb
industry. If you think that eating pineal glands is a dietary supplement,
we are talking different languages.
Scientists at the National Institutes of Health have expressed concern
about side effects of overdosing on melatonin. Although not clearly
proven, these concerns include decreased fertility, reduced sex drive
in males and damage to the retina of the eye. So trust your own physiology
to keep your hormone system fine-tuned. It rarely needs outside help,
especially from non-medical people.
DHEA - dehydroepiandrosterone
Anyone who wishes to learn about DHEA should see the above comments
on melatonin. The reason is that DHEA, like melatonin, is a naturally
occurring hormone in the body. It is made in the adrenal glands which
sit above the kidneys. It is present in small amounts in the blood of
males and females. It is a forerunner of the male androgen sex hormones.
The claims made for DHEA are almost exactly those for melatonin with
the addition that DHEA causes weight loss. These claims for DHEA are
rubbish. Virtually no human studies to support them have been done.
The Vit-Min-Herb industry has been able to say that this hormone is
a "dietary supplement" which is what the law allows them to say. If
you think that eating animal adrenal glands is a food supplement, then
you could probably rationalize its use. However, no scientist would
agree with you.
Are there any side effects to DHEA? Virtually nothing is known about
its long-term usage or its interaction with other drugs. Further, since
the hormone is a forerunner of the male sex hormone, testosterone, it
may masculinize females who take large doses and it may accelerate or
cause prostate cancer in the male. There is suggestive animal evidence
that the hormone may increase the risk of ovarian or breast cancer.
As with melatonin, don't mess with your own hormone system. It knows
how to keep you healthy far better than you or the Vit-Min-Herb industry
does.
Testosterone
In the male, this hormone declines with age. The Vit-Min-Herb sales
person and ads say that taking testosterone will restore vigor, energy,
decrease wrinkles and improve your sex drive. Such claims have never
been proven. Furthermore, taking testosterone can promote prostate enlargement,
including the growth of small cancers, cause high cholesterol and even
fertility problems. Never take testosterone without physician advice.
Estrogens
This is a hormone which has uncertain benefits for the post-menopausal
female. Recent studies now question its high use by the older female popultion. It may keep the bones strong, reduce the risk of heart attacks,
restore vaginal moisture and even skin elasticity. There is a slight
increased risk of breast and uterine cancer so this hormone should only
be taken under physician supervision.
Human Growth Hormone
This is often called hGH - human Growth Hormone. hGH is needed for normal
growth. It is produced in the pituitary gland at the base of the brain
and has an effect on the kidney, liver, heart, bone and muscles. It
is used medically to promote growth in those children who are congenitally
small and short. However, its other use is by those people, mostly men,
who want to increase their muscle mass. It will indeed do that but current
medical studies indicate that, while muscle mass may increase, the function
or strength of the muscle does not. This is a true drug and cannot be
purchased as a "food supplement." It must be given by injection and
the cost is over $15,000 per year. There are many unknowns about taking
this hormone, including increased cancer risk. Until much more is known,
hGH should be avoided unless prescribed by a physician experienced in its use.
Pycnogenol
These chemicals come from the bark of a pine tree native to Southern
France. The product contains about 40 different polyphenols and phytochemicals.
Naturally, those who sell it report that it has miraculous healing and
disease preventative properties. In the test tube these chemicals do act as antioxidants
which may neutralize free oxygen radicals in the body, but don't let
that word antioxidant excite you. While there may eventually be some
benefit proven for pycnogenol, at present, there is none according to
the FDA. Like selenium and Coenzyme 10, which are hyped for cancer and
heart disease prevention, there is no scientifically accepted evidence
for any of these substances. If you want antioxidants, do it the natural
way. Cocoa has the highest concentration (Jackson Fiber Cocktail). Blueberries, apples, oranges, and many other fruits, tea, onions
and many vegetables are very rich in these polyphenols and phytochemicals.
These are nourishing, nutritious, high-fiber foods with proven evidence
for risk reduction for cancer and heart disease. Do it the healthy natural
way.
Whatever
Don't you see a pattern? A medical, usually an animal study, is
published in an obscure or industry-supported publication which suggests
a benefit for a certain substance. The Vit-Min-Herb people call it a
"dietary supplement." They avoid FDA regulations and control. Now, they
get people, yes, even physicians, most of whom have a vested interest
in the product, to write articles in lay magazines, to be interviewed
on talk shows, to do infomercials - whatever. Bingo, a slickly packaged
health promising product is put in front of you. Amway-like multimedia
sales develop. Your friends are knocking on your door to sell you this
miracle product. Yet, it is completely unaccepted by the medical community.
The old saying is still true. If it is too good to be
true, then it is probably not true. Caveat emptor - let the
buyer beware.
