There are fat vegans and vegetarians. Hormones are delivered to beef by an implant behind the ear. Sure, a hormone implanted beef cow has more measured hormones in the beef produced than if it didn't have the implant. But the amounts are tiny in either instance. For example, Estrogenic activity is 0.85 per 3 oz in non-implanted. 1.2 per 3 oz in implanted. This amount is tiny, when you consider Soy has 128,423,201 per 3 oz and Tofu has 19,306,004 per 3 oz.
