easy to understand why people, and especially researchers, are interested in
finding ways to prolong life. A quick look at the term "longevity" on
the Internet reveals many sites promoting a number of different products. These are primarily combinations of vitamins, minerals, and antioxidants along
with a variety of additional components like enzymes, extracts of grapes or
green tea, and amino acids.
none of the websites I looked at, even one with a product named "LongevityTM,"
claimed that they prolonged life. Rather they make statements like "ward
off signs and feelings of aging" and "help you look younger and feel
great." Although I find it difficult to believe that older individuals
will attain such benefits from any of these concoctions, many people must be
wasting their money by purchasing them.
What about vitamin supplements?
many older people, especially those living alone or short of money, don’t get
adequate nutrition. There is no evidence, however, that anyone eating a well
balanced diet containing ample amounts of calories needs to take supplements of
any vitamin other than vitamin D or any mineral except for calcium. Further, in
regards to longevity, there's no proof that supplements play a role.
discovered anything we can take to increase our lifespan?
short answer is a resounding "No."
current misconception is around taking supplements of the hormone DHEA.
Produced in large amounts by the adrenal gland, DHEA has been touted to prolong
life. The possibility that this supplement is required to live a long life was
suggested by the finding that blood levels of DHEA fall dramatically with increasing
age in both men and women. But DHEA supplements have not been proven to promote
longevity. In fact, if you think about it, it would be extremely difficult if
not impossible to prove that any
medication or substance prolonged the life of humans. While it is possible to
show that specific treatments, such as lowering cholesterol levels or blood
pressure, have a relatively rapid impact on lifespan, it would take many years
and a huge number of study participants to prove that any substance increased longevity.
Instead, animal studies are likely the best way to at least find clues for
substances that might allow humans to live longer.
now the best advice on how to live a healthier and longer life are the well
known, good lifestyle habits of a healthy diet, weight control, regular
exercise, and avoid smoking.
