evidence: James Stangle, a doctor of veterinary medicine in South Dakota, has sounded the alarm on the Impossible Whopper, which, he says, contains so much estrogen that the mock-meat burger could grow breasts on men who wolf down too many of the Burger King sandwiches. "Now let me refresh your metric system," Stangle writes. "There are 1 million nanograms (ng) in one milligram (mg). That means an impossible whopper [sic] has 18 million times as much estrogen as a regular whopper [sic]. Just six glasses of soy milk per day has enough estrogen to grow boobs on a male." [...] Nutrition Action, a resource website produced by the Center for Science in the Public Interest, noted that the soy scare may have originated with a "2008 report in a medical journal about a 60-year-old Texas man who complained of sore, enlarged breasts and a decreased libido." Blood tests showed his estrogen levels were up to eight times higher than those at the top end of the normal range, the site reported.
