Colds are
a leading cause of doctor visits and missed days from work and school,
and this season is no exception. Americans suffer from approximately
1 billion colds per year, or about two to four colds per year for
the average adult.
But why do
people start getting sick as the leaves start to fall?
However, according
to the CBS News study, when you come down with chills, fever, cough,
runny nose, malaise and all those other "flu-like" symptoms,
the illness is likely caused by influenza at most, 17 percent of
the time, and as little as 3 percent! The other 83 to 97 percent
of the time it's caused by other viruses or bacteria.
So remember
that not every illness that appears to be the flu, actually IS
the flu. In fact, most of the time it's not.
Nevertheless,
as temperatures drop, we begin to congregate indoors and spend less
time in the sun. This means our vitamin D levels begin to drop,
and we are more apt to spread viruses from one person to another.
It isnt
that these opportunistic pathogens magically appear at certain times
of the year theyre always around. Its your ability
to respond to them that changes with the seasons.
It is important
to understand the causes of viral upper respiratory syndromes if
you want to avoid them.
The Real
Cause of Colds and Flu
Many people
believe that colds and flu are caused by bacteria, but this is simply
incorrect. Colds and flu are caused by viruses, and using antibiotics
to treat a viral infection is inappropriate and completely ineffective.
Viruses are
orders of magnitude smaller than bacteria and have entirely different
structures that make antibiotics useless. (Occasionally antibiotics
are required if there is a secondary bacterial sinus infection or
bronchitis/pneumonia, but this is the rare exception.)
It is also
important to recognize that, although a virus triggers your
cold or flu symptoms, it is not the real cause of the illness.
So, what is
the real cause of colds and flu?
My simple
and short answer has always been that its due to an impaired
immune system. Thats still true. However, research has confirmed
that catching colds and flu may be a symptom of an underlying
vitamin D deficiency! Less than optimal vitamin D levels will significantly
impair your immune response and make you far more susceptible to
contracting colds, influenza, and other respiratory infections.
Although there
are many ways you might end up with a weakened immune system, the
more common contributing factors are:
Vitamin
D deficiency, as previously mentioned
Eating too
much sugar and too many grains
Not getting
enough sleep
Insufficient
exercise
Inadequately
managing emotional stressors in your life
Any combination
of the above
THE Number
One Way to Conquer a Cold or Flu: Vitamin D
Vitamin
D is an amazingly effective antimicrobial agent, producing 200
to 300 different antimicrobial peptides in your body that kill bacteria,
viruses and fungi.
In the United
States, the late winter average vitamin D level is only about 15-18
ng/ml, which is considered a very serious deficiency state. Its
estimated that over 95 percent of U.S. senior citizens may be deficient,
along with 85 percent of the American public.
In 2009, a
team of researchers from Childrens Hospital Boston analyzed
blood samples taken from 5,000 children under age 12 and found that
nearly one out of five children in the U.S. have low blood levels
of less than 50 nanomoles per liter, the level recommended by the
American Academy of Pediatrics. They also found that two out
of three children have a level below 75 nmol/L which
is still insufficient, based on most of the research coming out
today.
No wonder
colds and flu run rampant each year.
The best source
for vitamin D is
direct sun exposure. But for many of us, this just isnt
practical during the winter. The next best thing to sunlight is
the use of a safe indoor tanning device. If neither natural nor
artificial sunlight is an option, then using oral supplements is
your best bet.
Remarkably,
researchers have found that 2,000 IU of vitamin D per day abolished
seasonal influenza. This is somewhat surprising, as it is half the
dose of what most adults need to achieve ideal levels of vitamin
D
Please note
that this is far greater than the recommended daily allowance (RDA)
advised by public health agencies like the American Academy of Pediatrics,
which recently doubled the RDA of vitamin D for children to 400
IU. This new guidance still falls absurdly short of whats
needed to keep kids healthy, especially during flu season.
In order to
prevent the flu, children and adults need 35 IU of vitamin D per
pound of body weight. So, for example, a child weighing 57 pounds
would need 2,000 IU a day of vitamin D.
Adults typically
need an average of 5,000 IU per day but some adults have
to take 20,000 to 30,000 IU daily to get their vitamin D level up
to optimal levels. Exactly how adults absorb and process vitamin
D so differently is still somewhat of a mystery, so the only way
to know if your vitamin D level is therapeutic and nontoxic is by
having your blood tested.
As you know,
Im not an extremist. I advocate balancing healthful choices
with enjoying life, which includes celebrating from time to time.
That said,
if you feel yourself coming down with a cold or flu, this is NOT
the time to be eating sugar,
artificial sweeteners or processed foods. Sugar is particularly
damaging to your immune system which needs to be ramped up,
not suppressed, in order to combat an emerging infection.
You must address
nutrition, sleep, exercise and stress issues the moment you first
feel yourself getting a bug. This is when immune-enhancing strategies
will be most effective.
When people
come down with a cold or flu, its because some combination
of factors has weakened their defenses. You might be able to get
away with one or two transgressions, but a bucketful of poor choices
will cause your immune system to crash. And then suddenly youre
sick.
When youre
coming down with a cold, its time to address ALL of the contributing
factors immediately.
This would
be a good time to tweak your diet in favor of foods that will strengthen
your immune response. Good choices include:
Mushrooms,
especially Reishi, Shiitake, and Maitake, which contain beta glucans
(which have immune-enhancing properties)
Garlic,
a potent antimicrobial that kills bacteria, viruses AND fungi
Herbs and
spices with high ORAC scores: Turmeric, oregano, cinnamon, cloves
(for more on ORAC, visit www.oracvalues.com)
Make sure you
are drinking plenty of fresh, pure water. Water is essential for
the optimal function of every system in your body.
Pay attention
to how you are sleeping.
If you arent getting enough sleep, or enough restorative sleep,
youll be at increased risk for a hostile viral takeover.
And dont
underestimate the importance of regular exercise for increasing
your resistance to illness. There is evidence that regular, moderate
exercise can reduce your risk for respiratory illness by boosting
your immune system.
But at the
same time, dont overdo it. Over-exercising can actually place
more stress on the body, which can suppress the immune system
and you dont want that either. You might just go for
a walk if you are coming down with something. Any rise in body temperature
will be an unwelcome climate for a viral invader.
Most of the
people incorporating a significant number of these wise lifestyle
choices into their daily lives simply dont get sick. And when
they do, its mild and short-lived.
Supplements
That Send Pathogens Packin
Supplements
can be beneficial, but they should be used only as an adjunct to
the lifestyle measures already discussed.
Some of the
more helpful ones for cold and flu are:
Vitamin
C: A very potent antioxidant; use a natural form such as acerola,
which contains associated micronutrients. (By the way, intravenous
vitamin C was recently used by a physician in New Zealand to cure
a man with terminal swine flu.)
Oregano
Oil: The higher the carvacrol concentration, the more effective
it is. Carvacrol is the most active antimicrobial agent in oregano
oil.
Propolis:
A bee resin and one of the most broad-spectrum antimicrobial compounds
in the world; propolis is also the richest source of caffeic acid
and apigenin, two very important compounds that aid in immune
response and even fight cancer.
A tea made
from a combination of elderflower, yarrow, boneset, linden, peppermint
and ginger; drink it hot and often for combating a cold or flu.
It causes you to sweat, which is helpful for eradicating a virus
from your system.
Olive leaf
extract: Ancient Egyptians and Mediterranean cultures used it
for a variety of health-promoting uses and it is widely known
as a natural, non-toxic immune system builder.
Another treatment
that is surprisingly effective against upper respiratory infections
is hydrogen peroxide.
My patients
have had remarkable results in curing the colds and flu within 12
to 14 hours when administering a few drops of 3 percent hydrogen
peroxide (H2O2) into each ear. You will hear some bubbling, which
is completely normal, and possibly slight stinging.
Wait until
the bubbling and stinging subside (usually 5 to 10 minutes), then
drain onto a tissue and repeat with the other ear. A bottle of hydrogen
peroxide in 3 percent solution is available at any drug store for
a couple of dollars. It is simply amazing how many people respond
to this simple, inexpensive treatment.
By incorporating
these strategies, youll be able to nip that nasty little virus
in the bud before it can say, Big Pharma.
