When you drive a car or truck the engine produces
exhaust. The same thing happens inside your body as it
goes through the millions of metabolic functions
necessary to keep you alive. |

Oxidative Stress Defined
Think back to the car or truck engine for
a moment. In order to burn fuel it requires
oxygen and this process--burning fuel for
energy--is called oxidation. This process is
basically the same for human cells which
need to burn something called "metabolites"
for energy. The "exhaust" created by cells
burning energy is called a free radical
toxin. Unfortunately these free radicals
have a piece missing, called an electron,
and each free radical is looking around for
a replacement. Where do they get a
replacement? From cells that are too weak to
defend themselves and each and every cell in
your body takes 10,000 free radical
(oxidative) hits every day to its DNA.
What's a DNA? Simply put it's the part of a
cell that tells it what it's there for and
what to do, and the damage is cumulative.
When you have too many of these free
radicals in your body they literally leave a
trail of damaged cell molecules that the
body has to clean up by either making new
ones, or if need be, replacing the entire
cell. This process puts a tremendous load on
the body called "oxidative stress". |

Sources of Oxidative Stress
Oxidative stress can come from both
inside and outside the body. Inside as your
body burns fuel for energy, and outside from
toxins which can cause cells to function
improperly. These toxins are invisible and
can come from the air we breathe, can be
absorbed through the skin, ingested through
food and liquid and can be created by the
body itself.
Let me give you one example of a well
known toxin--"second hand smoke!"
Endothelial cells line the heart, blood and
lymph vessels; if you smoke, the arteries
constrict or get smaller. If you breathe
second hand smoke the constriction is
exactly the same and it does non-repairable
damage to the circulatory system.
If this is true, and you are a smoker,
why quit? Because every cigarette does more
damage and the damage keeps adding up for
both the smoker and non-smoker. As a result,
oxidative stress is a major contributor to
disease and aging. In addition, the cells in
your body are outnumbered by free radicals
and since the body can't get rid of them on
its own, it needs help. This is why you
should care about what is going on inside
your body and how you can limit free radical
damage. |

What You Can Do!
Simply increase "antioxidant production"
in order to protect the cells! Good science
exists telling us that a diet rich in fruits
and vegetables is vital to good health and
prevention of disease. Special plant
nutrients called phytochemicals, found in
fruits & vegetables can literally be the
difference between life and death. Your diet
must contain key ingredients for bodily
needs. Some of these can't be manufactured
by the body itself, but must be supplied by
the foods we eat, called "essential
elements".

How Do Antioxidants Protect Us?
They have the ability to donate an
electron to the free radical, thus disarming
it. When the antioxidant donates an
electron, it becomes a free radical itself,
the difference being it is now more stable
and the body can get rid of it by flushing
it out. By reducing oxidative stress you can
reduce dysfunctions of the immune system
that lead to many diseases.

What About Antioxidant Supplements?
We can't get around the fact that the
body is going to produce free radicals as
food is burned for energy within the cells.
However, antioxidant supplements are not the
same as fresh-raw fruits & vegetables
because they are fragmented. For example,
more than 12,000 phytochemicals have been
identified in fruits and vegetables. An
"antioxidant" supplement has taken a given
number of nutrients out of the whole food
and isolated them in a "pill".

The Bottom Line
It is important to remember that
oxidative stress is in reality, cellular
damage which increases the likelihood of
advanced aging, cancer, diabetes, coronary
heart disease, hypertension, cataracts and
decline in immune system function. For us to
fight back it is recommended that we eat
5-9, and athletes 9-13, servings of fruits &
vegetables every day. Most people find this
difficult, if not impossible.
This is why we recommend Juice Plus+®,
the next best thing to fresh-raw fruits and
vegetables; proven by independent research
studies and published in peer-reviewed
journals.

Conclusion
Your best protection against the ravages
of oxidative stress on your body is to eat
the best whole foods possible, and then
bridge the gap between your best
efforts--and optimal nutrition--with an
antioxidant-rich complement to your diet. We
recommend using Nutripoints to
assist you with the best whole foods, and
Juice Plus+® as the best antioxidant-rich
complement.
Combine this with a regular and safe
exercise program, and managing stress
effectively, you will be doing your best to
slow the harmful effects of oxidative stress
in your body! |
