Most animal feed is soy-based. What effect does that have? Also, why would a vegan/vegetarian be against breast milk exactly? And finally: does anyone have any info on the effect of large soy consumption on males? I've been vegetarian for 6 months and trying to go vegan (mostly for past 1.5 months) so my soy consumption is at an all time high. Thanks!
