Soy sourced Beta-sitosterol is Genetically Modified (GMO)

In 1996 the first GMO (genetically modified) seed crop was invented and that was the soybean.  This GMO soybean  allowed the spraying of the toxic herbicide  “Roundup”.  In prostate health we first want the best ingredients and above all else “to do no harm”.

Ingredients that are free of phyto-estrogens (estrogen – feminizing hormone).  Some plants produce estrogen and hence these are called phyto-estrogens (‘phyto’ meaning plant).  One study in humans documented a 76% reduction in testosterone production in men. [1]  Another study by Nagata C, et al. “Inverse association of soy product intake with serum androgen and estrogen concentrations in Japanese men.” Nutr Cancer 2000; 36(1):14-8. This study in Japanese men showed that increased soy intake was related to decreased testosterone levels. In an additional study in healthy adult males compared a diet containing soy to one using meat as a source of protein. Testosterone levels were significantly lower in the group with a soy diet. In addition the amount of “free” testosterone was reduced by 7% in the soy diet group. [2]

Now more data has come forth with respect to the genetically modified origin of beta-sitosterol from soy sources (2014). The chances that the soy used in sourcing beta-sitosterol is genetically modified is approximately 93% (2014).  The worst part of this information is that this soy is being sprayed with glyphosate or Roundup.  Why is this bad?  Well they are now detecting glyphosate in urine samples.  Please see the attached video below.   This was despite individual’s best attempts to choose organic produce and live a clean life.  I guess all we can do is try our best to do what’s best and make informed choices.
