Free Redicals
- What
is Aging
Free
Radicals are simply molecules that
are missing an electrical charged electron that orbit in
pairs. In order to restore balance, it trying to snatch
one from any other molecule nearby - molecular terrorists (is
there any counter terrorists? Yes, the task belongs
to police force - antioxidants).
Free Radicals (molecular
Terrorists) create molecular disorder and confusion,
moving rapidly into the protein, fats and genetic DNA of cells,
spoil and corroding them. Especially when hits on DNA, the
cells' tiny power factories called mitochondria, cause
mutations that incite cells to aberrant behavior. Over time,
leaving the body aged and
diseased.
-
As we get older, the rate of
cell-damaging free radical reactions accelerates
dramatically.
-
As
we age, the abilities to defuse and repair the
damage from the free radicals (detoxification
system) lose steam.
-
It
is estimated that by age 50, about 30% of your
cellular protein has been turned into rusty junk by
free radical attacks.
-
80
~ 90 percent of degenerative diseases
involve free radical
activity.
-
Too much iron can make you old by
fostering free radical attacks on cells. (However,
menstruating women or child-bearing age women tend
to lose iron regularly in blood flow and may need
iron supplements. Also, children and adolescents
often do not get enough iron. Iron supplements may
require to correct the
defficiencies)
Important
Quotes
Through free radical
reactions in our body, it is as though we are being irradiated
at low levels all the time. They grind us
down.
- Lester Packer,
biochemist at University of California at
Berkeley
Trillion molecules of oxygen
go through each cell every day, inflicting about one hundred
thousand free radical hits or wounds on your cells' genes or
DNA, - Bruce Ames,
University of
California
Aging is a
disease. The human life span simply reflects the level of free
Radical Oxidative damage that accumulates in cells. When enough
damage accumulates, cells can't survive properly anymore and
they just give
up.
- Earl R. Stadtman, researcher on
ageing. National Institutes of
Health
Alcohal is
astonishing - it's a potent pharmacologic agent that can be
part of a healthy diet and can also be essentially fatal if
consumed in excess.
-
Dr. Walter Willett, Harvard School of Public
Health
The
different between drinking small and large amounts of alcohal
may be the difference between preventing and causing premature
deaths.
- Dr.
Charles Hennekens, professor, Harvard Medical
School
