It's actually phytoeostrogen in soya milk. Soy is in so many products it's unbelievable. Men should be more concerned with linseed/flaxseed.
I'm a rice milk fan. I get the one fortified with chickpeas. I also drink oatmilk sometimes and get soy milk from the coffee van that visits my work. Of them all, rice milk has the mildest flavour.

I find, if you've been drinking dairy, rice/oat/soya milks all taste pretty grim at first. The more you drink it to the exclusion of cows milk the better it tastes and then you don't notice it. If you try cows milk again after, it tastes sour and slimey. That has been my experience.
