Bisphenol A (BPA) is a widely used chemical substance. This
chemical exists in nearly every
plastic container, is used as lining for metal cans, and can even be found on receipts, toilet paper and
worldwide currency.
BPA leaches from its container into whatever it happens to contain. If you microwave a TV dinner for example, the chemical content of
the plastic container would find its way into the food you are going to eat. Likewise, when bottled water or a soft drink is
manufactured and shelved, BPA leaches into the liquid over the time it takes to be purchased and consumed.
Because of its widespread application in all forms of packaging, manufacturing and otherwise,
chances are that you are somehow interacting with this substance on a daily basis. Many other countries have
already declared BPA a toxin and prohibited its usage in a number of products.
It's in nearly everyone's
bloodstream. And now, Canada has declared BPA a toxic substance, both to the environment and to public
health.
BPA Death by Plastic - Special
Report
Aaron Dykes hosts a segment on Bisphenol A, the dangerous estrogenic in plastic drinking bottles
and food containers. BPA is a known toxic substance outlawed in Canada and Europe, but still used in the United
States, even though the FDA raised concerns regarding exposure of fetuses, infants and young children to the
substance.
Bisphenol A
(BPA) is a chemical building block that is used primarily to make polycarbonate plastic and epoxy resins. Use in
some food and drink packaging, e.g., water and infant bottles, compact discs, impact-resistant safety equipment,
and medical devices. Epoxy resins are used as lacquers to coat metal products such as food cans, beer cans, bottle
tops, and water supply pipes.
A known endocrine disrupter which in large quantities interferes with the release of
hormones, also known to cause Infertility and Cancer.

BPA’s Role in Disease
BPA is an endocrine disruptor. It mimics the natural hormones produced by your
body, specifically estrogen. When your body interacts with BPA, it delivers an estrogen-mimicking effect. This is
known to lead to a host of health problems including
infertility, cancer, weight gain and
more. This hormonal interference may also be responsible for
accelerating puberty and altering the growth of children, causing hormonal confusion.
Many studies suggest a widespread range of additional effects, including altered
immune function, neurological and behavior problems, heart disease, and diabetes. Even low levels of exposure can
cause adverse effects on health. Its been stated that 95% of paper money has been found to contain BPA, which
means that an equally large fraction of individuals worldwide have at some point been exposed to this chemical at
least from touching it on a regular basis.
What is more dangerous is that due to its use in food preservation, many people
are unwittingly consuming this harmful chemical, which is much worse than topical exposure. The widespread
effects of BPA are being increasingly recognized throughout the world. Despite this, once its presence in society
is removed, one can expect the number of health issues associated to vanish alongside it.
Canada Declares BPA Toxic. Why Isn’t the US Following
Suit?
November 02, 2010
Bisphenol A (BPA) is used in an enormous number of products. It's in nearly
everyone's bloodstream. And now, Canada has declared BPA a toxic substance, both to the environment
and to public health.
Canadian officials said that the declaration is the first step toward better
BPA regulation. Now that the chemical is classified as toxic, it's easier for the Canadian government to ban
BPA in specific products. Canada has already banned BPA in baby bottles, and the new listing will likely bring
an end to all food-related uses for BPA in the country.
Writing in Time Magazine, Bryan Walsh reports:
"The Canadian move was done in the face of intense opposition from the
chemical industry, which was quick to respond to the decision ...
What's clear, however, is that there is a growing public concern about the
possible impact of chemicals in the environment -- especially on pregnant women and developing fetuses
...
The science will never be fully certain, but the pendulum is moving in the
direction of a greater emphasis on safety -- and I think it's time."
Dr. Mercola's
Comments:
Bisphenol-A (BPA) has already been detected in the urine of 95 percent of people
tested, and with the outpouring of research showing it can trigger major changes in your body even at
low-level exposure, Canada is doing what's necessary … they're getting the ball rolling to get
BPAout of food
packaging and other consumer products.
"Concern for neurobehavioural effects in newborns and infants was suggested
from the neurodevelopmental and behavioural dataset in rodents.
Given that available data indicate potential sensitivity to the pregnant
woman/fetus and infant, and that animal studies suggest a trend towards heightened susceptibility during stages of
development in rodents, it was considered appropriate to apply a precautionary approach when characterizing risk to
human health.
Therefore, it was concluded that bisphenol A should be considered as a
substance that may be entering the environment in a quantity or concentration or under conditions that constitute
or may constitute a danger in Canada to human life or health."
Notice the term "precautionary approach" … this is what is sorely lacking in so
many areas in the United States,The U.S. Food and Drug Administration (FDA) frequently drops the ball when it comes
to regulating toxic chemicals like BPA and mercury.
BPA in baby bottles has been banned in Canada and several U.S. states. Other
measures are being considered in 30 U.S. states and municipalities -- but at a federal level, the FDA is treading
water.
Why?
Why Isn't the FDA Taking Action Against BPA?
According to the FDA, its regulatory framework limits its ability to regulate BPA
production.
That's right. Under its current construction, the FDA is unable to remove a toxic
chemical that is leaching into canned goods and other common foods as we speak, because it was
classifiedin 1963 as
an indirect food additive and is listed among the 3,000 or so chemicals categorized as GRAS ("generally regarded as
safe").
This outdated GRAS designation is what exempts BPA from more careful scrutiny and
analysis.
According to the FDA's regulations, a substance granted GRAS status
isnot subject to FDA review.The Agency explains these limitations via an
"update" on its website:
"Current BPA food contact uses were approved under food additive regulations
issued more than 40 years ago. This regulatory structure limits the oversight and flexibility of the
FDA.
Once a food additive is approved, any manufacturer of food or food packaging
may use the food additive in accordance with the regulation. There is no requirement to notify the FDA of that
use.
For example, today there exist hundreds of different formulations for
BPA-containing epoxy linings, which have varying characteristics. As currently regulated, manufacturers are not
required to disclose to FDA the existence or nature of these formulations.
Furthermore, if the FDA were to decide to revoke one or more approved uses,
the FDA would need to undertake what could be a lengthy process of rulemaking to accomplish this
goal."
The FDA's Hands are Tied?
What this means is that the FDA can ask chemical companies to volunteer
information about BPA, but this voluntary system does not have a history of working well when it comes to
corporations who have billions of dollars at stake.
As it stands, BPA is one of the world's highest production-volume chemicals and is
widely used in the production of:
Plastic water bottles
Plastic gallon milk bottles
Plastic microwavable plates, ovenware, and utensils
Baby toys, bottles, pacifiers, and sippy cups
Canned foods and soda cans (most have plastic lining in the
cans)
Tooth sealants
The American Chemistry Council, a lobby group for the chemical industry that
issued a statement in early 2010 denying the health hazards of BPA, clearly does not want to see this cash cow bite
the dust ... nor be held accountable for health problems related to its use. They will pull out all the stops to
keep this chemical in your food packaging, baby bottles, and more for as long as possible.
Meanwhile, the FDA has admitted that they can basically do nothing to get BPA out
of consumer goods without a formal change in the law, and this is despite the fact that
they've
acknowledged "concerns" related to its use:
" … [O]n the basis of results from recent studies using novel approaches to
test for subtle effects, both the National Toxicology Program at the National Institutes of Health and FDA have
some concern about the potential effects of BPA on the brain, behavior, and prostate gland in fetuses, infants, and
young children."
Congress has introduced legislation intended to establish
afederal ban on BPA in all food and
beverage containers, but for now the chemical is still widely used.
What Does the Research Say About BPA?
Of 115 published animal studies, 81 percent found significant effects from even
low-level exposure to BPA.
This toxic chemical, an endocrine disrupter, first caught researchers' attention
after normal mice began to display uncommon genetic abnormalities. The defects were linked to plastic cages and
water bottles that had been cleaned with a harsh detergent, causing BPA to leach out of the plastic.
After determining how much BPA the mice had been exposed to, the researchers
realized even an extremely small dose of 20 parts per billion daily, for just five to seven days, was enough to
produce effects.
Some of the greatest concern surroundsearly-life exposure to BPA, which can lead
to chromosomal errors in the developing fetus, triggering spontaneous miscarriages and genetic damage. And being
exposed to just 0.23 parts per billion of BPA is enough to disrupt the effect ofestrogen in a baby's developing brain.
For this reason, women of childbearing age and those who are pregnant should be
especially diligent at avoiding BPA, but practically no one is immune. One recent study found the chemical can lead
to heart disease, diabetes and liver problems in adults, and previous research has linked BPA to:
Structural damage to your brain
Hyperactivity, increased aggressiveness, and impaired
learning
Increased fat formation and risk of obesity
Altered immune function
Early puberty, stimulation of mammary gland development, disrupted
reproductive cycles, and ovarian dysfunction
Changes in gender-specific behavior, and abnormal sexual
behavior
Stimulation of prostate cancer cells
Increased prostate size, and decreased sperm
production
Diabetes
Heart disease
Liver damage
Tips for Staying Away From BPA
The Environmental Working Group is keeping tabs on BPA legislation in the United
States and globally, and you can
view its timeline here. As of late summer 2010, BPA bills were pending in
five state legislatures, and earlier this year numerous positive steps have been made to get this toxin out of U.S.
food containers:
Vermont banned BPA in baby food, formula and bottles, and will restrict its
use in metal food cans starting July 1, 2014
New York state banned BPA in bottles, sippy cups, pacifiers and drinking
straws beginning December 2010
General Mills announced in April 2010 that it would use BPA-free cans for
Muir Glen organic tomatoes starting with the next harvest
Hopefully this type of legislation will continue to snowball until a worldwide ban
is placed on this toxin, making it one less that you'll need to worry about. But in the meantime, the following
tips will help you to steer clear of BPA as much as possible:
Only use glass baby bottles and dishes for your
baby.
Get rid of your plastic dishes and cups, and replace them with glass
varieties.
Give your baby natural fabric toys instead of plastic ones, and only BPA-free
pacifiers and teethers.
Store your food and beverages in glass -- NOT plastic -- containers. Glass is
the safest and most inert way to store your water and food, and is far better than ANY plastic (even BPA-free
varieties).
IF you choose to use a microwave, don't microwave food in a plastic
container.
Use glass, ceramic, or stainless steel travel coffee mugs rather than plastic
or Styrofoam coffee cups.
Avoid using plastic wrap (and never microwave anything covered in
it).
If you opt to use plastic kitchenware, at least get rid of the older,
scratched-up varieties, avoid putting them in the dishwasher, and don't wash them with harsh detergents, as
these things can cause more BPA to leach into your food.
Avoid using bottled water; filter your own using a high-quality filter
instead.
Before allowing a dental sealant to be applied to your, or your children's,
teeth, ask your dentist to verify that it does not contain BPA.
Avoid using canned foods (including soda cans) as the linings often contain
BPA. If you do eat canned foods, choose only those thatcome in BPA-free cans.
BPA causes changes to your brain, not just your
body
Bisphenol A (BPA) has been a
chemical item of great health concerns for the past few years. It's common in many plastics, including plastic food
and beverage containers, inner epoxy linings of cans used for canned foods, thermal paper, and paper
money.
BPA leaches into the liquids and foods in those containers. It also leaches into your
blood through the skin while handling paper money and thermal paper, commonly used for printing
receipts.
Although the FDA refuses to consider BPA unsafe, other nations have. Several have
banned BPA. The researched health hazards include links to cancer, especially breast cancer, and hormone imbalances
causing physical/sexual manifestations that affect both genders of all ages.
Even a CDC,Centers for Disease Control
and Prevention, 2003-04 study found that 93 percent of over 2,500
Americans surveyed had measurable BPA in their blood. Unfortunately, BPA remains in the bloodstream for a long time
unless the right nutritional antidotes are taken, which are discussed later in this article.
That means expectant mothers can pass BPA on to their newborns while in the womb and
afterward while breastfeeding. Also, beware of plastic baby bottles that aren't BPA free.
BPA also affects the brain and nervous system
A recent animal study using mice atNorth Carolina State University proved that the
brain and nervous system are also affected adversely by BPA. Here's their research paper published in the
journalPLOS ONE.
(http://www.plosone.org)
Summarizing: The rats were divided into different groups, some fed BPA levels
comparable to human levels, some not fed BPA, and others fed BPA with soy. They discovered that early exposure
toBPA causes gene expression changes that affect the
molecules of a part of the brain known as the amygdala.
This region of the brain is responsible for dealing with response to fear and stress.
It also affects social behavior. Another human pediatric study determined neurological effects from BPA at three
years of age, especially among girls. Anxiety and/or depression were the common symptoms.
Ironically, soy's estrogen mimicking element,genistein, seemed to counteract or block BPA's estrogen
mimicking ability in the study. That's like fighting fire with fire. The scientists doing this research seem to
desire exploring soy's BPA neutralizing properties.
They probably don't know why many informed foodies reject soy: Most are GMOs; non-GMO
soy is difficult to digest unless fermented, and just how would they know when the BPA level has been neutralized
by soy, allowing soy's genistein to take over the estrogen mimicking function, causing problems all over
again?
Preventing and getting rid of BPA
Phase into glass and ceramic containers as much as possible. If you must use
plastic, try to keep the container cool and out of sunlight. Plastic containers have recycle numbers placed with
triangles, usually at the bottom of the container. Those numbered one or five are the least harmful.
If a canned food item doesn't have "BPS-free" on the label, leave it on the shelf.
After handling thermal paper or paper money, wash your hands thoroughly. If your work demands considerable handling
with either type of paper, try wearing thin latex gloves.
Now here are those antidotes to BPA's estrogen mimicry:
Increase probiotic consumption. Probiotic supplements should include bifidobacterium
breve, lactobacillus casei, bacillus pumilus, and bifidobacterium 3.
Instead of expensive supplements, you can use homemade water or milk kefir, and
fermented foods such as kimchi, sauerkraut, miso, and tempeh. (http://www.naturalnews.com)
Black tea and Royal Jelly also work well. Supplementing with melatonin (for sleep
only), folic acid, or quercetin are other good choices. Genistein extracts are contraindicative to pharmaceuticals
for allopathic breast cancer patients.
Caveat: Bisphenol-S (BPS) may have
replaced BPA in many products. Though apparently not as strong, its properties are similar to BPA.
A new
report saysBisphenol A (BPA),
the controversial hormone disrupting chemical widely used in plastics, is turning up in an unlikely place–the
money in your wallet.
Ericka Schreder, a staff Scientist with
WTC and author of the report, says lab tests confirm the chemical rubs off receipts onto the skin after
holding it for just 10 seconds. WTC researchers first tested 22 thermal paper receipts collected from
businesses in 10 states and the District of Columbia. Half contained higher than trace amounts of BPA. They also
tested 22 $1 bills and found BPA on 21 of them. Schreder says contamination most likely occurs once receipts come
in contact with money in places like wallets and cash register drawers.
"Levels on dollar bills were lower than on receipts,
but the fact that our currency is contaminated with a hormone-disrupting chemical illustrates how our current
chemical law is failing us," Schreder says. "Even the most careful consumer can't avoid BPA when it's so pervasive
that it even contaminates money."
But Kathryn St. John, a BPA specialist at
theAmerican Chemistry Councilsays while some receipts made from thermal paper can have low levels of BPA, research shows
it's safe.
"To the limited extent BPA is absorbed through the
skin, it is converted to a biologically inactive metabolite that is rapidly eliminated from the body," St. John
said. "Biomonitoring data from the U.S. Centers for Disease Control shows that consumer exposure to BPA, which
would include any exposure from receipts, is extremely low. Typical exposure from all sources is about 1,000 times
below safe intake levels set by government bodies in Europe and the U.S. In comparison, the trace levels of BPA
claimed to be present in dollar bills are insignificant."
In
July,The Environmental Working
Groupreleased a similar study about BPA and cash register receipts. EWG researchers tested 36 and
found 40 percent had high levels of the chemical.
Environmental
groups and public health advocates have linked BPA to a number of serious health problems including cancer,
diabetes, infertility, early puberty and heart disease. According to theNational Institute of
Environmental Health Sciencesat the National Institutes of Health (NIH), 93
percent of urine samples from people over the age of 6 have detectable levels of BPA, but research linking
some health problems—particularly in adults–to the chemical has been inconclusive. Still, earlier this year
the FDA said recent studies "provide reason for some concern about the potential effects of BPA on the brain,
behavior, and prostate gland of fetuses, infants and children."
"We need to update the 1976 Toxic Substances Control
Act with a new chemical law that both requires companies to provide health information on chemicals they produce
and ensures that chemicals that can cause cancer, infertility, and other health problems can't be used in everyday
products."
