In a study published in the June 2007 issue of the journal Environmental Health Perspectives, authors Stahlhut et al, report that they have found that “phthalate (a plasticizer) metabolites showed statistically significant correlations with abdominal obesity and insulin resistance.” The correlations were found in a cross-section of US males. The mechanism they believe is the way that this man-made chemical can reduce androgen (e.g. testosterone) production and/or function. In a number of human studies, men who have had androgen deprivation therapy have shown increases in serum glucose, total fat and have shown the propensity to have a greater chance of having metabolic syndrome.
The study, available from the EHP journal free of charge, has major implications. As some of you may know from my lectures around the world and some of my blogs here, I have always asserted that there is a link between toxicity and obesity. Here is yet another powerful study that shows yet another reason why we need to keep on our toes and make sure that our bodies are able to detoxify efficiently. It also leads to the answer to the proverbial chicken vs egg question, but here it is which came first, obesity (fat is a gerat storage place for toxins) or toxicity. I firmly believe, toxicity is one of the causative factors of the obesity epidemic. My suspicion is that these toxins cause people (even young children) to crave, then eat to excess, sugars and fats to deal with their increasing insulin resistance issues.
Testing for two urinary metabolites of phthalates is easy and inexpensive. Have your physician contact Lab Interpretation LLC and ask for the Environmental Pollutants Biomarker test from US Biotek. Not only does it measure urinary output of phthalates and monoethyl phthalates, it looks at metabolites of xylene, toluene, benzene, trimethylbenzene, styrene and parabens. Since almost every human on earth now has detectable levels of a number of toxins flowing through their body, it is imperative that we measure whether we excrete the toxins effectively.
In today’s toxic world, you need to know your enemy so you can effectively deal with it and find the sources of exposure.
