Plastic chemical triggers allergic asthma

Font size: Decrease font Enlarge font

A plastic chemical commonly used in baby bottles and the lining of food and beverage cans may at least partially responsible for allergic asthma, a new study suggests.

The animal model study presented Sunday in New Orleans at the American Academy of Allergy, Asthma & Immunology annual meeting  showed the mice born to the mothers who were exposed to bisphenol A or BPA suffered allergic asthma.

BPA has been known to cause a myriad health problems.  Even Food and Drug Administration, which initially rejected the link between BPA exposure and health conditions, has recently admitted that BPA can potentially be harmful.

Dr. Erick Forno of pediatrics at the University of Miami Miller School of Medicine and colleagues early have found that baby mice born to mothers who had been exposed to BPA were at higher risk of allergic asthma.

In the current study, Dr. Forno and colleagues intended to decide what levels of exposure would affect the animals.

What the researchers did is prepare drinking water with 0.1 1 or 10 micrograms per ML of BPA and give it female mice before, during and after pregnancy.  Baby mice were given ovalbumin immediately after birth to induce asthma.

They found mice born to mothers exposed to 10 micrograms of BPA developed airway problems while mice  born to mothers exposed to low or no BPA did not develop the problem.

Allergic asthma is the most common type of asthma that affects some 90 percent of children with asthma and 50 percent of adults with asthma.

Individuals with allergic asthma have their airways hypersensitive to the allergens and when they are exposed to allergens, they may suffer coughing, wheezing, shortness of breath, rapid breathing and tightening of the chest, symptoms that are commonly experienced by patients with non-allergic or allergic asthma.

The allergens of concern include  pollen from tress, grasses and weeds, mold spores, animal dander and saliva, dust mite feces and cockroach feces among others.

Studies by The Environmental Working Group suggested that BPA contamination in canned food are likely to put consumers at risk of ingesting doses of the chemical that are very close to levels now known to harm laboratory animals.

EWG scientist Sonya Lunder said parents should choose BPA-free types of baby bottles or water bottles and formulas with a label claiming BPA-free to avoid BPA exposure. Babies are more sensitive than adults to the harm from the chemical and they also ingest more than adults.   

Lunder also suggested pregnant women should minimize exposure to canned foods and polycarbonate food containers, and BPA-containing medical devices.

Early studies have found associations between BPA and high risk of abnormal behavior, male reproductive system, heart disease immune system, the brain, breast cancer, metabolic syndrome, heart attack and diabetes among other diseases.

We also hear that BPA is in all the Composite Dental Filling materials, that are used in place of Mercury, also a heinous substance, and that many people mistakenly kid themselves that replacing Mercury with BPA is somehow safe when both are toxic waste, and so one almost has to conclude that this is intentional contamination of the public.

Obviously Mercury is dangerous, but so is BPA, neither should we be exposed to, it is not either or, it is neither nor !!!

All Pharmaceuticals are dangerous, unnecessary, same with all dental products & procedures except extractions, all repairs, both medical and dental should be based on your own DNA, yes all, no foreign materials of any kind, we are not dry wall, or a car fender to be patched with bondo etc, these people are out of control, as if the human body would not know how to heal itself if allowed to. British Royal commonly let their teeth go, they are not stupid, they know all this stuff is deadly, it is not afterall like they could not afford it, yet they don't, just as most doctors do NOT vaccinate their own children, because they too know.

Dr Angelito-Good post. Why would anyone in their right mind put Mercury and or BPA in fillings if not to do mischief to the population?

There are demons out there who are intent on harming normal folks be by Aspartame, MSG, Sucrose etc etc.

Dont even get me started on the vaccines !!

"Baby mice were given ovalbumin immediately after birth to induce asthma."

What sick monster would deliberately induce this disease in innocent animals?

Dr. Weston Price discovered and proved that the quality of nutrition in the local diet was able to facilitate immunity to decay of teeth and other physical degeneration. He was able to arrest decay and promote remineralization by simply adusting the diet to supply sufficient quantities of the key nutrients in their natural bioavailable form as found in properly prepared food. See chapter 16 and 22 of his book "Nutrition and Physical Degeneration" found at ppnf.org.

The higher level of concern for possible effects of bisphenol are on prostate gland, mammary gland and early onset of puberty in exposed fetuses, infants and children.

I know one thing, most people should be drinking out of glass instead of plastic. Plastic heats up and tends to be very porous, stainless steel bottles are good to drink from as well.

I agree. Food has become so cheap in the U.S., Americans, as well as "others", have no respect for it. They consume it and throw it away like it was their reason for being born. That includes everything else sold in the U.S.: clothes, shoes, everything. Unfortunately for the U.S. the idea of making everything cheaply has come at the price of any and all standards this country ever had, including any services it provides. When inhumane treatment of animals became acceptable as a country, it wasn't long before its citizens became expendable, i.e.: homeless then joblessness. NAFTA was a great idea. I'm glad we don't have homelessness or joblessness anymore. I'm glad American standards became more superior not less. Or, public education, police, fire departments...

But, these are the results of the "Free Market". Anything for a buck, right? Anything.

The United States never addressesd and reconciled the compensation of the labor of its citizens or the waste and environmental hazards created back in the 60s and 70s, so our government / corporate america's answer (beginning with Reagan's administration) was to accept American homelessness, incarcerate citizens, promote greed, export the jobs of hardworking American citizens who dared to demand a living wage and make more waste around the world.

At the rate we're going, we'll be devolving to turn of the century working conditions and slavery. Oh, yeah, we already have. See slavery situation in Hawaii defended by Democrats and Republicans alike.

P.S. Norma Rae never got her wage increase or benefits and many Americans of Mexican descent were farmworkers, too, but the Union ddoesn't work when immigrants undercut their "co-workers".

One more comment. Why is our government still using Tobacco smoking as the whipping boy for asthma related deaths and illnesses. Recently, a PSA propagandizes "...1 death every 6 seconds"... . Really?
