Study Finds Connection Between Prenatal Exposure To BPA And Aggression During Toddler Years

(NaturalNews by Jonathan Benson, staff writer) Researchers from the Harvard University School of Public Health have made a disturbing new discovery about the plastics chemical bisphenol-A (BPA). It turns out that prenatal BPA exposure can spur aggressive and undesirable behaviors in girls after they are born and reach their toddler years.

Published in the journalPediatrics, the study analyzed a group of 244 mothers and their three-year-old daughters living in the Cincinnati, Oh., area. The study team gathered and studied gestational and childhood BPA exposures using urine samples from the mothers, and compared various exposure levels among the children to their respective behavioral profiles.

The team discovered that for each ten-fold increase in gestational BPA exposure levels, young girls exhibited significantly more indicators of anxiety and depression than their less- or non-exposed counterparts. Young girls exposed to high BPA levels were also more emotionally disturbed than the others and had a more difficult time controlling their inhibitions.

The National Institute of Environmental Health Sciences and the US Environmental Protection Agency (EPA) jointly funded the study as part of an investigation into the safety of BPA.

"Parents should be concerned about these findings," says study author Joe Braun. "As the mothers concentration of BPA rose, the girls born to those mothers had higher scores on these behavior problem indices. If pregnant women or parents are concerned about exposure to BPA, they can try to reduce it by limiting their exposure to canned foods and packaged foods."

Although these particular findings were limited strictly to females, previous studies have found a similar connection between prenatal BPA exposure and poor behavior in both sexes. Back in 2009, a study published in the journalEnvironmental Health Perspectivesfound that BPA's endocrine-disrupting effects can harm both girls and boys.

Besides impairing proper neurological development, which is likely the reason for behavior problems later in life, prenatal BPA exposure was found to "masculinize" unborn females, and "feminize" unborn males. It appears, based on that study, that BPA actually blocks the proper growth and development of human sex hormones (http://www.sciencenews.org/view/gen...).

Both the US Food and Drug Administration (FDA) and the American Chemistry Council (ACC), however, continue to insist that BPA is safe, despite the plethora of scientific data showing that the chemical is harmful.

BPA Alters Development Of In Vitro Ova And Could Increase Risk Of Down Syndrome

Bisphenol A is omnipresent in the plastic of common products such as beverage bottles, cans or baby bottles

Universitat Autònoma de Barcelona, in collaboration with the Vall d'Hebron Hospital Fetal Tissue Bank, the Department of Gynaecology and the Research Unit of Paediatric Endocrinology, analysed the effects of Bisphenol A (BPA), a polymer widely used to manufacture plastics, in an in vitro culture of ovaries. The research demonstrated that exposure to this substance gravely altered the development of oocytes and future ova, possibly diminishing the fertility of a woman's offspring and at the same time increasing the risk of Down Syndrome in following generations.

The research, published in Human Reproduction, was carried out with a culture of 21,570 in vitro oocytes. Results demonstrated that exposure to Bisphenol A in concentration levels permitted by health authorities is harmful to the fetus. BPA reduces the number of oocytes (cells which develop into ova) and therefore can affect negatively a woman's fertility and double the risk of chromosome exchange during the cell division process. Specific observations of chromosome 21 in the development of 90 oocytes revealed that exposure to BPA could increase the risk of Down Syndrome in the future offspring of the fetus.

The research provides conclusive data for the debate on how BPA affects the health of individuals. Previous studies on mice and worms demonstrated that reproduction is affected and that exposure to BPA during gestation affects the viability and quality of the cells which later become ova developing in the fetus.

For the first time, human cells were used in a research to analyse the process of cell division of the oocytes - meiosis - in which chromosomes join and exchange material, i.e. meiotic recombination. Oocytes were cultured for 7, 14 or 21 days in different environments, with the presence of BPA and in control cultures without the substance. Data obtained in vitro with human cells was practically identical to that obtained with in vivo animal models, while the effects on meiotic recombination, which could lead to the appearance of Down Syndrome, in humans are even greater than those observed in mice.

"According to our results, BPA does not directly affect the fertility of pregnant women, but that of their daughters and granddaughters. It is a multigenerational effect", explains UAB professor Montserrat Garcia Caldés, director of the research. She goes on to say that "the increase in oocyte mortality in the fetus could diminish ovarian reserve numbers and the quality of the future mother's ova. At the same time, alterations in the recombination of chromosomes in the process of cell division increase the possibility of numerical alterations, such as monosomy (only copy of a chromosome in embryo cells) or trisomy (three copies)."

Concentration levels applied in the experiments were within the safety limits marked by European (EFSA) and US (EPA) authorities. The research therefore suggests that staying within legal limits does not imply that exposure to the substance is innocuous.

"We are exposed to BPA on a daily basis, mainly through oral exposure, since we can find it in lunch boxes,beverage bottles and food storage containers", Miguel Àngel Brieño-Enríquez reminds us. First author of the article, Brieño-Enríquez, from the University of San Luis Potosí, Mexico, is now researcher at the UAB Department of Cell Biology, Physiology and Immunology. According to him, "although we generally metabolise the substance, pregnant women retain more fluids and the fetus could be affected by high concentration levels."

Health Buzz: BPA Linked to Sperm Problems

Bisphenol A, or BPA, May Hurt Sperm

by Kurtis Hiatt

Exposure to bisphenol A (BPA), a chemical found in everything from plastic bottles to tin cans, may harm sperm, suggests a study of about 200 Chinese factory workers. The five-year study, published in the journal Fertility and Sterility, compared men who were directly exposed to the chemical on the job to men who were not; it found that those with high levels of BPA in their urine were more likely to have poor semen quality—including low sperm concentration and issues with sperm mobility—than those who had low levels of BPA in their urine, NPR reports. Although previous studies have linked BPA to reproductive problems in male rats, this study is among the first to suggest a negative effect on sperm in humans, according to a press release from Kaiser Permanente, which conducted the study. However, the workers in the study were exposed to much higher BPA levels than the average American, according to NPR, and it's unclear if the impact on sperm would affect their fertility. Still, "The general public should probably try to avoid exposure to BPA as much as they can," De-Kun Li, an epidemiologist at Kaiser Permanante's Division of Research in Oakland, Calif., told the Washington Post. (Li and colleagues have published two similar studies linking BPA to sexual problems in men.)

BPA's potentially detrimental effects extend beyond sperm. In January, the U.S. Food and Drug Administration voiced concern about its adverse effects, especially on fetuses, infants, and young children. A 2008 study even linked the chemical to diabetes and heart disease. Here are some good rules of thumb for reducing your exposure to BPA, U.S. News's Deborah Kotz writes.

From: 5 Ways to Keep BPA Out of Your Food

1. Buy your tomato sauce in glass jars. Canned tomato sauce is likely to have higher levels of BPA because the high acidity of the tomatoes causes more of the chemical to leach from the lining of the can. Think beyond plain tomato sauce to any canned pasta—like ravioli and those fun-looking kids' meals.

2. Consume frozen or fresh fruits and vegetables instead of canned. In addition to their BPA-free benefit, fresh and frozen produce usually have more nutrients, which often get lost in the process of canning. Eden Foods does offer canned beans that are BPA-free.

3. Purchase beverages in plastic or glass bottles. Canned soda and juice often contain some BPA. You don't need to worry, though, about disposable plastic water bottles. Most don't contain bisphenol A, and those that do are usually marked on the bottom with a number 7 recycling code.

4. Use powdered infant formula instead of ready-to-serve liquid. A separate assessment from the Environmental Working Group found that liquid formulas contain more BPA than powdered brands.

5. Think in terms of moderation. You don't need to avoid all canned foods. Just consult the chart below and follow a sensible approach, eating less of those foods that are high in BPA. Click here for the full report on canned foods.

List Of Ingredients To Avoid

Below is a mostly complete list of the most common ingredients found in processed foods. Here is your first assignment toward taking responsibility for your health,
  1. Train yourself to read labels. You and only you are responsible for your health.
  2. Commit to memory these ingredients (or carry a cheat sheet)
  3. Avoid products that contain the ingredients below.

(All punctuation by the author Mike Adams)
"Acrylamides- Toxic, cancer-causing chemicals formed in foods whencarbohydratesare exposed to high heat (baking, frying, grilling). They're present in everything from bread crusts to snack chips, and because they aren't intentional ingredients, acrylamides do NOT have to be listed on labels.

Aspartame- Chemical sweetener that causes neurological disorders, seizures, blurred vision and migraine headaches. (http://www.naturalnews.com/030918_a...)

Autolyzed Proteins- Highly processed form of protein containingfree glutamateand used to mimic the taste-enhancer chemical MSG.

BPA (Bisphenol-A)- A hormone mimicking chemical found in nearly all food packaging plastics. Active in justparts per billion, BPA promotes cancer, infertility and hormone disorders. It also "feminizes" males, promoting male breast growth and hormone disruption (http://www.naturalnews.com/032860_B...).

Casein- Milk proteins. Hilariously, this is widely used in "soy cheese" products that claim to be alternatives to cow's milk. Nearly all of them are made with cow's milk proteins.

Corn Syrup- Just another name for High Fructose Corn Syrup (see below). Frequently used ininfant formulaproducts (http://www.naturalnews.com/029863_S...).

Food Colors- FD&C Red #40, for example, is linked to behavioral disorders in children. Nearly all artificial food colors are derived frompetroleum, and many are contaminated withaluminum.

Genetically Modified Ingredients- Not currently listed on the label because the GMO industry (Monsanto and DuPont) absolutely does not want people to know which foods contain GMOs. Nearly all conventionally grown corn, soy and cotton are GMOs. They're linked to severe infertility problems and may even cause the bacteria in your body to produce and release apesticidein your own gut. If you're not eating organic corn, you're definitely eating GMO corn. (http://www.naturalnews.com/026426_G...) Learn more atwww.ResponsibleTechnology.orgor watch myGMO music video(hilarious) atwww.NaturalNews.com/NoGMO

High Fructose Corn Syrup- A highly processed liquid sugar extracted with the chemical solventglutaraldehydeand frequently contaminated with mercury (http://www.naturalnews.com/032948_h...). It's also linked to diabetes, obesity and mood disorders. Used in thousands of grocery items, including things you wouldn't suspect like pizza sauce and salad dressings.

Homogenized Milk- The fats in the milk are artificially modified to change them into smaller molecules that stayin suspensionin the milk liquid (so the milk fat doesn't separate)(http://www.naturalnews.com/022967_m...). While it makes milk look better on the shelf, it's also blamed for promoting heart disease and may contribute to milk allergies.Raw milkis healthier, which is why the government had outlawed it (http://www.naturalnews.com/029322_r...).

Hydrochloride- When you seeanythinghydrochloride, such as Pyridoxine Hydrochloride or Thiamin Hydrochloride, those arechemical forms of B vitaminsthat companies add to their products to be able to claim higher RDA values of vitamins. But these are synthetic, chemical forms of vitamins, not real vitamins from foods or plants. Nutritionally, they are near-useless and may actually be bad for you. Also watch out forniacinamideandcyanocobalamin(synthetic vitamin B-12). (http://www.naturalnews.com/032766_c...)

Hydrolyzed Vegetable Protein- A highly processed form of (usually) soy protein that's processed to bring out the free glutamate (MSG). Use as a taste enhancer.

Partially Hydrogenated Oils- Oils that are modified using a chemical catalyst to make them stable at room temperature. This createstrans fatty acidsand greatly increases the risk of blocked arteries (http://www.naturalnews.com/027445_f...). It also promotes what I call "sludge blood," which is thick, viscous blood that's hard to pump. This is usually diagnosed by doctors as "high blood pressure" and (stupidly) treated with blood-thinning medications that are technically the same chemicals asrat poison(warfarin) (http://www.naturalnews.com/023149_d...).

Phosphoric Acid- The acid used in sodas to dissolve the carbon dioxide and add to the overall fizzy-ness of the soda. Phosphoric acid will eat steel nails. It's also used by stone masons to etch rocks. The military uses it to clean the rust off battleships. In absolutely destroys tooth enamel (http://www.naturalnews.com/021774.html). Search Google Images for "Mountain Dew Mouth" to see photos of teeth rotted out by phosphoric acid:http://www.google.com/search?q=moun...

Propylene Glycol- A liquid used in the automotive industry to winterize RVs. It's also used to make thefake blueberriesyou see in blueberry muffins, bagels and breads. (Combined with artificial colors and corn syrup.) See shocking "Fake Blueberries" video at:http://www.naturalnews.tv/v.asp?v=7...

Sodium (Salt)- The processed white salt lacking in trace minerals. In the holistic nutrition industry, we call it "death salt" because it promotes disease and death. Real salt, on the other hand, such as "dirty" sea salt or pink Himalayan salt, is loaded with the trace minerals that prevent disease, such as selenium (cancer), chromium (diabetes) and zinc (infectious disease). Much like with bread and sugar,white saltis terrible for your health. And don't be fooled by claims of "sea salt" in grocery stores. All salt came from the sea if you go far back enough in geologic time, so they can slap the "sea salt" claim on ANY salt!

Sodium Nitrite- A cancer-causing red coloring chemical added to bacon, hot dogs, sausage, beef jerky, ham, lunch meats, pepperoni and nearly all processed meats. Strongly linked to brain tumors, pancreatic cancers and colon cancers (http://www.naturalnews.com/007024.html). The USDA once tried to ban it from the food supply but was out-maneuvered by the meat industry, which now dominates USDA regulations. Sodium nitrite is a complete poison used to make meats look fresh. Countless children die of cancer each year from sodium nitrite-induced cancers.

Soy Protein- The No. 1 protein source used in "protein bars," including many bars widely consumed by bodybuilders. Soy protein is the "junk protein" of the food industry. It's made from genetically modified soybeans (often grown in China) and then subjected to hexane, a chemical solvent (http://www.naturalnews.com/026303_s...) that can literally explode.

Sucralose- An artificial chemical sweetener sold as Splenda. The sucralose molecule contains a chlorine atom (http://www.naturalnews.com/027491_a...). Researchers have repeatedly found that artificial sweeteners make people fat by actually promoting weight gain (Y).

Sugar- The bleached, nutritionally-deficient byproduct of cane processing. During sugar cane processing, nearly all the minerals and vitamins end up in the blackstrap molasses that's usually fed to farm animals. (Blackstrap molasses is actually the "good" part of sugar cane juice.) Molasses is often fed to farm animals because every rancher knows that farm animals need good nutrition to stay alive. Amazingly, conventional doctors don't yet realize this about humans, and they continue to claim that eating sugar is perfectly fine for you. Sugar promotes diabetes, obesity, mood disorders and nutritional deficiencies.

Textured Vegetable Protein- Usually made of soy proteinwhich is extracted from genetically modified soybeans and then processed using hexane, an explosive chemical solvent (see Soy Protein, above). Widely used in vegetarian foods such as "veggie burgers" (most of which also contain MSG or Yeast Extract, by the way).

Yeast Extract- Hidden form of MSG that contains free glutamate and is used in many "natural" food products to claim "No MSG!" Yeast extract contains up to 14% free glutamate. You'll find it in thousands of grocery store products, from soups to snack chips. I even once spotted it used on fresh meat!"
