Health Update - Understanding Colds and Flu:
Their Prevention and Treatment
Did you catch our Internet Radio Show on “Cold & Flu Prevention and Treatment”? It is available in the
webcast archives at www.healthcoach.ca/radio/.
Many medical experts consider the influenza virus (cause of the "flu") to be the most dangerous virus in the
world. Each year about 20,000 people in North America die from the flu. Several times in past history, this
virus has been responsible for killing huge numbers of people within a 1 to 2 year period. As an example,
the "Spanish flu" (type A [H1N]) of 1918-19 killed about 500,000 people in the U.S. and at least 20 million
people worldwide. In 1957-58, the "Asian flu" (type A [H2N2]) resulted in 70,000 deaths in the U.S., and in
1968-69, the "Hong-Kong flu" (type (A [H3N2]) killed 34,000 in the U.S.
Because of the health risks the influenza virus creates, vaccines were developed to help protect us. The risks
from receiving a flu shot are quite minor relative to the risk of not for those who need it most – those at
highest risk, such as babies, pregnant women, people over age 65, or those with a compromised immune
system or a chronic disease.
The choice of whether to receive a flu shot or not, is not the only one to be made though. This choice may
not even be the most important one for many with respect to how healthy they will stay throughout this
years cold and flu season. What is the Flu?
Let's pause here and take a moment to get a clearer picture of what the "flu" really is. Terminology and
language can be fickle and non-specific masters, and so the common day-to-day use of the term "flu" has
evolved to often encompass anything from a "common cold" to a true "flu". The "stomach flu" is another
misleading term, often used to describe a gastrointestinal illness (the "stomach flu" is usually not even
caused by a virus but by other microorganisms). So, the first critical point to understand is that the "flu" is
not a common cold or a stomach infection.
When researchers or doctors speak of the "flu", they are being very specific and mean an infection by the
influenza virus. Epidemic influenza is divided into type A and type B. The most common presentation of
influenza includes a fever (usually 100-103 degrees F in adults), respiratory symptoms (such as cough, sore
throat, runny or stuffy nose), headache, muscle aches, and, often extreme fatigue. So, the second key point is
that public health officials and doctors mean influenza virus when they use the term "flu".
The year-in, year-out "flu" can be deadly as we have just discussed, especially for babies, the elderly, people
with compromised immune systems, or those who have an existing chronic health condition, such as
asthma, diabetes or heart disease. Even for those of us who are in generally good health, the "flu" can still
really "take the wind out of our sails", and cause us to feel miserable for several days to a week or two.
Cold and Flu Prevention and Treatment / Page 1
Currently there are several main subtypes of the "flu" in circulation. These subtypes are broken down into 2
families -- type ‘A’ and type ‘B’. The type A family subtypes are the "Hong Kong" type A (H3N2) virus
and its relatives (responsible for about 400,000 deaths in the United States since 1968 (90% of which are
among the elderly), and distant relatives of the "Spanish Flu", type A (H1N1). Since 2001, a new subtype of
influenza A – type A(H1N2) – has been found in several parts of the world including North America.
Whether this new flu subtype will go into long-term widespread circulation and cause the same problems as
the other type A subtypes is uncertain. Only one form of type B influenza virus is in circulation. When
describing the subtype of influenza, the "H" and "N" refer to viral proteins called haemagglutinin (H) and
the neuraminidase (N).
Some medical and public health experts believe it is only a matter of time (in fact they think we are
overdue) before a new pandemic (worldwide epidemic) of the "flu" occurs, killing many, many people. Why has the flu been able to kill such large numbers of people so quickly in the past?
We are going to oversimplify here, but follow along. The "flu" virus is able to genetically rearrange itself or
change over time, allowing it to re-infect us year after year. Usually this is a slow and very gradual process
of genetic rearrangement (both type A and B influenza virus can change in this manner).
As an example, if you were exposed to last year's "flu" virus, your immune system would have created a
very specific immune system memory of how to effectively deal with the virus. A new exposure to the same
identical virus would not now be a problem. However, since the virus changes a slight amount each year,
last years immune memory will not completely protect us from this year's influenza infection. But the
building blocks of immune system memory will be in place (assuming we have a competent immune
system) so soon after infection, most of us will mount an aggressive immune system response. We might
feel ‘fluish’ for a few days to 2 weeks, but our immune system will eventually sort things out.
Getting a flu shot, simply acts as a form of immune system teaching; the immune system is given a reminder
of what the circulating types of influenza virus look like. This allows it to be a bit better prepared should it
encounter the virus. So the flu shot basically speeds up the recall and response process. It doesn’t mean you
are immune to the flu. It doesn’t mean you won’t get it. It just means that if you do get exposed to it your
immune system will have a bit of a head start in terms of knowing what to do and beginning to do it.
However, you should also be aware that every once in a while, the type A "flu" virus (the type B does not
change in this manner) can have a big change to either its haemagglutinin (H) and/or neuraminidase (N)
proteins. This results in a new strain of the virus, which is not recognized as something your immune system
dealt with in the past. When there is this type of big genetic rearrangement it isn’t even something the flu
shot can protect against. The reason for this is that the flu shot is designed based upon the types of flu virus
in circulation, not those that might suddenly come into existence.
In other words, a flu shot can only teach you to recognize and respond to the types of flu that we already
know are in circulation. If a brand new subtype pops into existence, a vaccine is relatively useless, because
none of the new subtype would be represented in the vaccine. This is important – a flu vaccine only teaches
our immune system about the known existing subtypes of influenza that are already in circulation; it doesn’t
and can’t prepare us should there be a big genetic change in the circulating influenza viruses.
Why is this important? It is important because in the years that the "flu" virus became a worldwide epidemic
and killed millions of people, the "flu" virus underwent big genetic rearrangement and changed in this
Cold and Flu Prevention and Treatment / Page 2
manner. If this type of big genetic rearrangement were to happen again (and many experts believe it is not a
matter of “if” but “when”), the flu shot would not afford a great deal of protection. In fact, if there is a
significant genetic rearrangement of the virus, it might not provide any protection. The only thing that could
protect us if the ‘flu’ virus undergoes a big genetic rearrangement is having robust anti-viral immune system
Is there a role for homeopathic medicines here?
This is not the place to go into the theories behind homeopathic medicine, but many years of clinical
experience and many thousands of clinical trials have demonstrated certain homeopathic remedies to be
uniquely effective and completely safe to infants and elderly alike. Homeopathic remedies can be used as
part of your immune system training, in similar fashion to the flu shots we have been discussing. They can
also be used as a part of the treatment to minimize or eliminate the symptoms of an acute cold or flu
infection. Readers are encouraged to discuss if homeopathics should play a role in their personal cold and
flu prevention program with their Health Coach. (Note, those at high risk to harm from influenza should not
consider themselves suitably protected by either the flu shot or the homeopathic equivalent alone.)
Whether it is a typical ‘flu’ year, when very little genetic rearrangement of the virus occurs, or an
unexpected year, when the ‘flu’ virus in circulation is very different from last years ‘flu’, a ‘flu’ shot is only
part of a proactive approach. A comprehensive proactive approach would also include (1) nutritional
strategies to maximize ‘seroconversion’ to the vaccine (Note: seroconversion is the process of immune
system learning and response to the vaccine), and (2) homeopathic, nutritional and lifestyle actions to build
robust anti-viral immune system defenses. Do you want to be proactive in a comprehensive way and be
ready for this year’s flu season?
What can I do to be proactive in a comprehensive way?
Step 1: If you are going to get the flu shot
If you are going to get the flu shot it’s important that you get the most benefits out of it. For the flu shot to
work the way it is supposed to, our immune system must actually learn from it. This process of learning is
called ‘seroconversion’. This simply means that our immune system responded to the vaccine and created
the specific type of memory cells the vaccine was intended to create. This process of learning can be
improved by optimizing your nutritional status. To ensure you get the type of nutritional support to best
prepare your immune system to learn and respond appropriately (‘seroconversion’) to the flu vaccine make
sure you complete a Health Coach® Assessment and answer “Yes” to the question that asks:
Will you be having any upcoming vaccinations
in the next 6-8 weeks?
Answering “Yes’ will ensure that your individualized nutritional program will identify and recommend
nutritional factors with an ability to enhance and support this important ‘seroconversion’ part of the
vaccination process. [If you’re already on a custom nutrition program through your Health Coach, and have
been for several months, your levels of key nutrients may well have been optimized already, but due to
seasonal variations in our assessment recommendations and depending on when you last updated your
assessment, you’re best to check and make sure you’re program is a 2007 Fall or Winter update.
Optimizing our nutritional levels of vitamins C & E, adaptogenic herbal support, and ensuring adequate
probiotic bacteria intake and trace mineral intake are some of the important nutritional steps that can prepare
your immune system to have the appropriate “seroconversion” to vaccines. Within the Health Coach®
Assessment, built-in logic and associated rules automatically adjust for seasonal variations in your needs for
Cold and Flu Prevention and Treatment / Page 3
Step 2: Whether or not you get the flu shot and/or homeopathic preventive support: The best defense is a good offense
. Improving the capabilities of our immune system’s anti-viral defenses
before we get sick is a far more proactive health strategy than would be waiting to support our immune
system after we are already sick. With this in mind, nutritional and botanical strategies exist which have an
ability to support our immune system defenses so that these defenses can (1) reduce the likelihood of getting
a cold and/or flu, (2) accelerate our recovery time should we get exposed, and (3) minimize the likelihood of
having any type of post-viral infection complication. An immune enhancing herb called Andrographis has
been found to improve our immune system’s performance against viral assaults, especially when combined
with other key nutritional elements, in a way that supports all of the above. An adaptogenic herb called
Ginseng also can be of benefit in maximizing the memory and response features of our immune system to
ensure that we are better prepared, from an immune system perspective, should we be exposed to cold
and/or flu viruses, as has properly dosed vitamins E and C in select groups studied. To ensure you get the
type of nutritional support to best prepare your immune system so your immune system can be operating in
a manner that both reduces your risk of infection and enhances your recovery if you are exposed, be sure to
complete the Health Coach® Assessment and answer “Yes” to the question that asks:
Do you want to take pro-active nutritional steps to improve your immune system's ability to resist
by viruses that cause colds and the flu?
Answering “Yes’ will ensure that your individualized nutritional program will identify and recommend
nutritional factors, including Andrographis and Ginseng, with an ability to enhance and support the immune
system’s ability to go on the offense should we be exposed to the types of viruses that cause colds and flu.

your truest nutrient and lifestyle needs.
Every bit as important to your natural immunity is your lifestyle. Your day-to-day eating, exercise and sleep
habits, your stress exposure, lighting conditions and more, all factor into how well your immune system
responds to the challenges it encounters, including exposure to viruses and pathogenic bacteria. In case you
are not aware, completion of the Health Coach® Health & Lifestyle Assessment leads to a thorough analysis
of the each of the key areas related to your health and provides guidelines for improvement. Following these
guidelines is very important to minimizing your risk to developing a significant cold or flu and in large part
dictates how well you handle it.
Whether you are following our diet and lifestyle guidelines, on a properly tailored nutrient supplement
program, used homeopathics, and had a flu shot, or not, we highly recommend that you be prepared to
respond immediately to the onset of a cold or flu. 25+ years of clinical experience with thousands has
taught us the benefits of catching any infection early and responding appropriately. Keep the most proven
nutrient support for the treatment of acute colds and flu on hand throughout the season. The NutriScan
product “Immune Support Plus” has bundled all 3 in convenient single dose packets.
Cold and Flu Prevention and Treatment / Page 4
Note: At the first sign of any infection, or when you find yourself over-tired and/or over-stressed, chilled
etc. take a packet, and repeat again each 3-4 hours. If symptoms are present, continue to repeat the single
packet dose 3-4 times daily until they have been clear for 2 full days (to ensure the infection is resolved and
avoid any rebound flare up). For prevention purposes you can use one of the ingredients – Andrographis,
daily or take 1 Immune Support Plus packet per day, morning preferred.
Another key aspect of natural immunity has to do with the health of our “barrier” functions. Beneficial
bacteria are on our skin and line the surface of the parts of our internal cavities that interface with the
outside world (like our respiratory and digestive systems). These beneficial (probiotic) bacteria are an
important part of our first line of defense against viral exposure because they help us to win the battle before
the virus gets past them and makes its way inside our cells and starts to replicate. Because of this, daily
consumption of the probiotic organisms found in NutriScan’s “Probiotic” product can be a critical part of
creating and sustaining a good offense (included within the majority of NutriScan custom nutrient programs
due to the lack of these beneficial organisms in today’s diet).
Another key component of a good offense is making sure that our overall nutritional status is in tip-top
shape. Insufficiencies in most vitamins (especially vitamin A, C, and E) and minerals (including iron,
selenium, and zinc) handicap our immune system. Ensuring that our diet and nutritional program identifies
and supports these and other nutritional needs can go a long way towards building the type of powerful
immune system we need to safely see us through the upcoming flu season. Here again, NutriScan’s
evidence-based rules engine ensures your levels of each of these essential nutritional elements are included
in your properly personalized nutrient program. It is important to note that “too much of a good thing, is no
good at all”. “More” is not better when it comes to nutrient support. Appropriate dosing is essential for
safety and efficacy.
If you are not on a custom program where our rules engine protects against both insufficiencies and
excesses, be sure to have your Health Coach review any nutrients you are taking.
Whether or not you will be getting the flu shot, there is always more you can be doing to better prepare
your immune system for the upcoming cold and flu season
. Whether it is optimizing the body’s response
to the vaccine or working independently to give your immune system a nutritional helping hand, let
NutriScan® be a part of your flu and cold season solutions.
