I was recently reading an article from an informative website, www.t-nation.com, when I came across an older article about Xenoestrogens. Reading this article spurred me to further research estrogen, which is a group of hormones synthesized by the reproductive organs, the adrenal glands and adipose tissue. Too much or too little estrogen can lead to hormonal imbalance and has been linked to a number of health problems.
Estrogen is a necessary female sex hormone, which controls menstruation and reproduction. However, with our society there are a number of man-made chemicals that mimic estrogen coming from outside of the body. This leads to a hormonal imbalance, further exposing oneself to some very serious health problems. The American Cancer Society has listed exposure to estrogen as a risk factor for breast cancer. So what are these man-made chemicals that we are all exposed to?
Dr. Williams, who was interviewed in this T-Nation article, defines Xenoestrogens as man-made chemicals that can enter the body and mimic the effects of the female hormone estrogen. Dr. Williams goes on to explain how Xenoestrogens can make the effect of estrogen (or the synthetic chemical itself) more profound on the body by binding to the same receptor that estrogen binds to. This can lead to an elevated level of estrogen, causing a severe hormonal imbalance.
Women are not the only ones who are susceptible to this hormonal imbalance. Xenoestrogens affect both females and males. Men are particularly susceptible to prostate cancer with increased estrogen exposure. An increase in estrogen and a decrease in testosterone can cause increased body fat, reduced muscle mass and decreased strength in men.
How can one avoid excess exposure to Xenoestrogens? Buy glassware instead of Tupperware! Numerous studies have shown that xenoestrogens can leach from plastic polycarbonates. The softer the plastic, the worse it is. Pesticides and herbicides, as well as commercial meats grown with hormones, carry Xenoestrogens. Try to buy organic produce whenever possible and seek out grass-fed beef and/or free-range chicken at your nearest Whole Foods, Henrys or local market.
Don’t be too alarmed by all this information as the effects of Xenoestrogens are still being researched. It is good, however, to be proactive and eliminate as much exposure to these man-made chemicals as you can.
