Be Afraid, Be Very Afraid

This is a terrific article that talks about the ghosts and goblins (i.e. toxic chemicals) lurking in our families' food and water; what they can do to our health; and tips to keep your family safer.  Please take the time to read it and then share it with your friends.  I always say "knowledge is power."

9 Tips for Cancer Prevention

This is an excellent article and one that should be copied and posted on the refrigerator.  It should also be shared with everyone you know.

When you read that "Four of every 10 Americans will be diagnosed with cancer in their lifetimes, and two of every 10 will die from it"  this should raise some eyebrows and motivate all of us to take action.

More BPA Woes

Early-life exposure to BPA may affect testis function in adulthood

ScienceDaily (2010-06-22) -- Exposure to environmental levels of the industrial chemical bisphenol A, or BPA, in the womb and early life may cause long-lasting harm to testicular function, according to a new study conducted in animals. ... > read full article

BPA Blues

This is an excellent review of some of the latest studies on BPA and their results.  Dr. Chaney makes a good case for a preventative appraoch to health management.

By Dr. Stephen Chaney, PhD

You've heard the saying "An ounce of prevention is worth a pound of cure" - and sometimes we don't really know what we are preventing until after the fact.


Toxic chemicals such as BPA are a case in point!  Bisphenol A or BPA is a chemical additive that has been added to clear plastic bottles for years, but we are just now starting to learn how toxic it is.

Recent studies have suggested that BPA increases the risk of heart disease, diabetes and liver disease...
...and the news keeps getting worse!

One recent study showed that BPA prevents the formation of nerve connections in the portion of the brain that controls formation of memories and control of moods (Leranth et al., Proc. Natl. Acad. Sci., 105:14187-191, 2008) - in short that BPA may negatively affect brain function.

That had been previously shown in mice, but what makes this study so concerning was that the authors demonstrated the same effect in monkeys - and at doses that the EPA considers to be "safe" for humans.

The second study in the August 14, 2008 issue of Environmental Health Perspectives showed that BPA suppresses a hormone called adiponectin which is responsible for maintaining normal weight and preventing the development of metabolic syndrome - a precursor to diabetes.

Those data suggest that BPA may increase the risk of both obesity and diabetes.

All of these potential health consequences of BPA exposure are especially concerning in light of a recent study showing that 90% of the US population has BPA in their urine.

So does that mean that it is too late - that there is nothing that we can do to prevent the damage caused by an environmental toxin that we were all exposed to but did not know about until recently?

The answer is no.

As I pointed out in a previous "Health Tips From the Professor" (Bad Effects Of Additives In Plastics, archived at: http://www.socialmarketingconnection.com ) those of you who have been taking a preventative approach and making sure that you had plenty of folic acid and genistein (a phytonutrient found in soy protein) in your diet may have protected yourself from the bad effects of BPA.

So, my word of advice to all of you is follow a holistic approach to health that includes weight control, exercise, good diet and supplementation.

It will help protect you from the dangers that you know about and the ones that you don't.

To Your Health!

Endocrine Disruptors: Where do we find them?

In the first installment I defined endocrine disruptors as exogenous substances (coming from outside the body) that act like hormones in the endocrine system and disrupt the physiologic function of endogenous (inside the body) hormones.

So the next logical question would be where are these hormone-like substances found? Some man-made chemicals found in household products that we use daily – cleaners, laundry products, personal care products – are likely suspects. These chemicals are also found in many of the foods we eat. We are exposed through the air we breathe, the food and water we take in, and the products we absorb through our skin (think shampoo, body lotion, cosmetics, etc).

Here is a sampling of chemicals thought to be endocrine disruptors:

Phthalates – used to make plastics more flexible and durable. It is used in PVC plastic found in upholstery material, shower curtains, floor tiles & children’s toys. It is also found in toiletries (especially nail polish), toothbrushes and insect repellents. (This is just a very small sampling.)

Bisphenol A (BPA) – is a component of plastic used in the lining of food cans & bottle tops. It is also in polycarbonate plastics like soft drink containers, water jugs and baby bottles.

Dioxins – not intentionally produced, dioxins are released into the environment as a by-product of chemical processes involving chlorine. Most dioxin is emitted into the air and then deposited on grass and trees and consumed by cows and other animals; or it goes into lakes and streams and ingested by fish. Ninety-five percent of our exposure is through meat, fish, and dairy products.

PVC (polyvinyl chloride) aka vinyl – one of the most common plastics. Manufacturing and burning PVC creates dioxins. It has been used widely in upholstery, home furnishings, children’s toys and hundreds of other products.

Detergents – a class of chemical surfactants that dissolve and remove oils and grease and make products more water soluble. They are found in ordinary household products like laundry detergents, all-purpose cleaners, personal care products like soaps, shampoos shaving foams, cosmetics and spermicides.

Other Endocrine-Disrupting Compounds: Pesticides, lead, cadmium and mercury.

Pesticide are used on food crops and home gardens, and are also found in flea collars, lice shampoo and even under the foundation of your home.

I just want to say that this is a daunting subject and cannot possibly be covered thoroughly in a few blog posts. I would encourage each of you reading this to please do your own due diligence and learn what products you should remove from your homes and replace with safer alternatives.
