A Cesspool of Pollutants
Now Is the Time to Clean-up Your Body
www.drmcdougall.com
Manufactured chemicals permeate every
tissue of every person on this planet. The threat from these
synthesized chemicals is real � even though you can�t see, taste,
smell, or touch them, they can rob you of your happiness, family
relationships, intelligence, and years of productive life. Two
reasons we sometimes fail to make the connection between these
manufactured pollutants and disease are: their effects are insidious,
taking years to reveal their damage; and not everyone is equally
susceptible to injury � genetic strengths and weaknesses determine to
a large part whether you will be harmed. Inefficient metabolism and
incomplete removal of these toxins from your body place you at great
risk of damage. Your greatest defenses are to avoid these pollutants
in the first place; and secondarily, to take effective actions to rid
your body of these poisonous substances.
Persistent Organic Pollutants
Well-known sources of these synthetic
chemicals are pesticides, herbicides, building materials, and
industrial wastes � these substances are collectively referred to as
persistent organic pollutants (POPs).
Before the early decades of the 20th
century, POPs were virtually non-existent in our environment.
The absence of these pollutants may be one reason for the robust
health exhibited by many grandparents, even when most ate a diet high
in meat and dairy products.
Production and distribution of POPs
expanded dramatically following World War II to where today nearly 900
active ingredients are found in our food, water, homes, schools, and
workplaces. Some are more toxic than others are, but their additive
effects make a strong case for banning the use of the entire class
of these chemicals, not just a few of the worst offenders.
No one should be surprised that
POPs are harmful; after all, the intended use for many is to kill
living organisms � pesticides kill bugs and herbicides kill weeds.
How could you expect that they would be harmless to you and your loved
ones?
POPs Damage the Unborn
The threat to the unborn begins years
before children are conceived, by accumulating for entire lifetimes in
the bodies of future mothers and fathers. Potential mothers with
heavy loads of POPs have a higher risk of spontaneous abortions. In
one study, more than 50% of the population of women attending a
fertility program had had exposure to environmental chemicals
sufficient to produce detectable concentrations in their blood and the
fluids found in their ovaries.1
The human fetus is exposed to
environmental pollutants through the placental connection to the
mother. These POPs disrupt activities of hormones � like estrogen,
androgen, and thyroid hormones � during critical periods of
development in the uterus, producing adverse effects, such as altered
social skills, decreased intelligence, and reproductive
difficulties.2 At school-age, these same children are
found to have lower IQ scores.2
To reduce the risk of pollutant-damage
to your unborn it is imperative that women planning to have children
at any time in life begin a healthy low-pollutant diet when they
themselves are young children. Men are not exempt from this directive
� a man�s sexual abilities and, ultimately, potency can be seriously
impaired by the pollutants in his diet.
POPs Devastate Children
Children are not simply
small adults. They take in more food, and thus more chemicals,
relative to their body weight than adults do; and their developing
tissues are more sensitive to the effects of the pollutants. As a
result, estimates are that 50% of lifetime exposure to pesticides
occurs during the first 5 years of life.2
Once born, the ideal food for an infant
is breast milk. Unfortunately, mother�s milk has been declared a
health hazard because of POPs � infants suckling from mother�s breast
receive huge quantities of pollutants she has been accumulating all of
her life. Mother�s milk is inherently high in fat; therefore,
chemicals are attracted to and concentrated by her milk-fat
(bio-accumulation). Levels of pesticides may be 6 to 7 times higher
in her breast milk than in her blood.2
These POPs are so efficiently delivered
to the baby that approximately 20% of the mother�s lifelong burden of
pesticide is transferred to her infant over the first 3 months of
breast feeding.5 Countries which have taken steps to ban
POPs show a decline in levels of these chemicals in the breast milk of
their citizens. The message to all families is to teach your children
that they must take steps now to keep their bodies clean � the life
and health of their future families depends on prudent planning.
(Note: Even though the milk is
polluted, breast milk is still essential for your baby and formula
should almost never be substituted � despite the contamination. See
the McDougall Program for Women book).
Brain Damage from POPs
Most pesticides work by interfering
with the nervous system of the insect, so findings of decreased mental
(cognitive) function in people exposed to pesticides and other
environmental chemicals (like PCBs) should be no surprise.6,7,8,
Convincing examples of this toxicity to the brain are seen in
people who work with these chemicals; for example, sheep farmers who
were exposed to organophosphate pesticides in the course of dipping
sheep to rid them of infestations performed significantly worse than
non-exposed farmers in tests to assess sustained attention and speed
of information processing.9
Parkinson's disease is a common brain
disorder affecting approximately 1% of the population of the USA over
65 years of age. Studies show that exposure to pesticides causes
Parkinson's disease in humans.10,11 The mechanism behind
this damage has also been largely revealed. The enzyme systems that
metabolize these brain-damaging chemicals, like the herbicide Paraquat,
have been identified. Estimates are 5 to 10% of people from white
populations are poor metabolizers of these chemicals, because they
have undetectable enzyme activity � this is a genetic trait. In these
unfortunate people, the chemical remains in their system causing
insidious brain damage over many years of exposure.
Decontaminating Your Body
The key to removing the pollution from
your body is to remove these POPs from your surroundings. First, you
need to understand that 89% to 99% of these chemicals gain access to
your body through your food. More importantly, the foods with the
highest levels of contamination are those foods high on the food chain
� meat, poultry, fish, and dairy products.5,7,21-23
The reason these animal foods are the
primary source of pollution is because their fatty tissues attract and
concentrate chemicals � a process known as bioaccumulation.
The poisons are concentrated as they move up the food chain resulting
in biomagnification of the chemical threat.
Plant foods are of low risk to you.
Contamination of plants with pollutants is largely a surface
phenomenon resulting from spraying herbicides and pesticides on the
plant or particles carried by air or water to the surface of the
plant.24 Therefore, most of the contaminants can be
removed by thoroughly washing and peeling these plant foods before
cooking and eating.
You also need to avoid sources of
pollution found in your home and workplace. Get rid of the chemicals
around your house and look for nontoxic ways to control pests.
Further information is easily found by searching the Internet for
�nontoxic pest control.�
Benefits of Organic Foods
Organic farming practices are intended
to protect farm workers, ensure food safety, and minimize the
environmental effects of pesticides. In general, organic agriculture
produces foods without the use of synthetic chemicals. Although
improved nutritional quality of organic produce is often argued,25
providing the cleanest foods for your family is the primary
reason to spend the extra time shopping for and money you invest in
buying organic produce.
Meat and poultry can carry the label
�certified organic.� Organic meat, poultry, egg, and dairy products
come from animals that are given no antibiotics or growth hormones,
and are processed without the use of bioengineering or ionizing
radiation. However, the POP content of the �certified organic� animal
foods will depend upon the level of pollution in the animals� feed.
Meat and poultry certified organic are supposed to be raised on
�organic feed,� and therefore should have less POP contamination.
Among the worst examples of polluted animal food comes from �farmed�
salmon.35 The high levels of POPs in the feed given to the
farmed salmon makes them �toxic� compared to ocean-caught salmon.
Because of biomagnification of POPs from the environment, animal
foods, regardless of the efforts to grow and/or harvest them �clean,�
will provide a greater source of contamination than plant foods raised
with similar efforts.
Detoxification by a Healthy Diet
The human body has detoxification
systems that have evolved over 300 million years to protect animals
from the natural toxins found in plants. These same systems will also
rid your body of synthetic pollutants. These natural detoxifying
compounds are found in plants, and they are also potent inhibitors of
chemically-induced cancer.29-32 In addition, the energy
required for the detoxifying processes is most effectively provided by
clean burning carbohydrates � carbohydrates are found in plants (meat,
fish, poultry and vegetable oils have no carbohydrate and cheese has
only miniscule amounts). Not surprisingly, malnutrition from under-
and over-nutrition (such as when people eat the American diet), almost
invariably leads to a reduced capacity to deactivate these pollutants
and therefore increases their toxicity.32
Losing weight on any �diet� releases
stored pollutants as the body fat is dissolved.33,34 This
is good, especially when the diet you are using to cause the weight
loss is free of pollutants and full of detoxifying substances �
meaning a diet of starches, fruits and vegetables � and even better, a
diet focusing on organic vegetable produce.
Unfortunately, the most popular diets
these days � Atkins, South Beach, Zone, etc. � are centered around the
most contaminated of all foods � meats and dairy products. Can you
see the futility of trying to �clean your body� by loading it up with
�dirty foods?� At the same time that you may be losing weight and
releasing toxins into your bloodstream, you are filling it up with
POPs from every mouthful of polluted food.
Special Cleansing Programs?
Most �cleansing programs� warn against
eating animal foods and recommend organically grown plant foods. I
support that foundation. However, many of these programs also
recommend colon cleansing, coffee enemas, vitamin supplements, and
special �super� foods (like barley green) as an integral part of their
therapies. I have not found scientific support for adding any of
these approaches to the benefits of simply eating a healthy diet.
Saunas and skin-cleaning are also recommended to eliminate the poisons
through the skin. Although this approach may be of some benefit,
scientific support is again lacking. Water �fasting� could be a
speedy way to eliminate body fats holding on to pollutants. However,
this form of extreme undernutrition lacks the energy from
carbohydrates which is necessary for removing synthetic chemicals, as
well as lacking the �natural� detoxifying compounds which are
plentiful in plants. Therefore, at the risk of appearing redundant I
recommend � as I do with so many other troubles affecting people �
that you eat a simple and clean diet of starches, vegetables and
fruits � and add some exercise to increase safe fat loss.
