Toxic Body Fat – PBDs
Lipophilic means tending to mix with fats. Over the last 100 years, we have flooded our environment with thousands of lipophilic toxins, including pesticides, herbicides, and chemicals from building products, household products, furniture, carpets, and industrial waste (1).
The high levels and increasing contamination of human breast milk in the US and Canada provides ample evidence of widespread distribution of lipophilic toxins in our environment (2-4). I will take the example of just one of them–the much used flame retardants known as polybrominated biphenyls (PBDs).
PBDs in North America
In North America, levels of PBDs in breast milk are now among the highest in the world (4;5)—higher than levels found in Europe or Asia. To put it in perspective, PBDs in human breast milk in North America are much higher than the legal limit for any other form of milk.
Elevated PBDs in breast milk have been linked with lower birth weight and smaller heads in newborns (6). In a study conducted in the Netherlands, high blood PBD levels in mothers at the 35th week of pregnancy correlated with defective motor function, defective cognition, and disordered behavior of the child measured up until age six (7). In New York City, prenatal PBD exposure (as indicated by cord blood PBD levels) was linked with lower scores on tests of mental and physical development at the ages of 1 to 4 as well as age 6 (8). A recent controlled study in Spain (9) reported decreased attention and cognitive and motor scores in infants and children exposed to PBDs.
EPA phasing out PBDs
The evidence against PBDs is now so strong that the US Environmental Protection Agency is phasing them out. But, just like the insecticide DDT, PBDs will remain in the environment for our lifetime. Bald eagles in California still show high levels of DDT even though they were all born decades after the chemical was banned. Like DDT, PBDs can persist in the body for decades, slowly damaging the brain and shortening lifespan.
The ray of hope is the miracle of the human body. As a living, constantly renewing organism, it’s able to be cleansed of such harmful toxins and chemicals. Regular cleansing routines emphasizing a high intake of water and nutritional support–along with reductions in body fat–enable the body to excrete most toxins.
You clean your teeth daily in order to maintain them. Your health will benefit a great deal more if you also clean your body daily, from the inside out.
