Crazy huh? No this is not some new ad like you would see in Muscular Development. This actually has some truth behind it. Drinking bottled water increases testosterone levels in men!
A recent study led by Peninsula Medical School and the University of Exeter and published in the latest issue of Environmental Health Perspectives have for the first time identified changes in sex hormones related to Bisphenol A, better known as BPA exposure. BPA is an organic compound with two phenol functional groups used to make polycarbonate plastic and epoxy resins used in products like CDs, DVDs, all kinds of plastic items and yes, water bottles. It has been used for over 70 years.
This study measured the amount of BPA exposure through BPA excreted per day in urine samples in 715 subjects between the ages of 20 and 70. The average exposure level was just over 5 micrograms per day. The study revealed that higher BPA exposure is statistically associated with increased levels of testosterone in the blood. The higher the BPA exposure, the higher the levels of testosterone.
Another study revealed that subjects exposed to BPA from plastic water bottles had 67% higher BPA concentration in their urine after just 1 week.
It’s pretty clear BPA exposure has an effect on the human body. It’s getting a lot of negative associations a the moment. Hey, when you got lemons – make lemonade.
