My understanding is there isn't much evidence of a link between soy an almost anything positive or negative (unless you have an allergy). "Plant estrogen" is different enough from human estrogen to be at most a weak form of the same.

Consider for example that it's highly popular in China, Vietnam, Korea, and Japan, and Japan has one of the highest life expectancies, second only to an autonomous region of China: https://en.wikipedia.org/wiki/List_of_countries_by_life_expe...

They do, but are mostly armless if consumed reasonably: don’t eat the same meal every meal!

A sheep got complications in the 40´s although no strong adverse effect have been found off human despite many studies and big consumption in Asia since a long time : 40mg/d in Japan/China while 3mg/d in EU/US (1): you may safely x13 your soy consumption if you live in the west.

Don’t worry either if you’re a men, you’ll be just fine (2)

Post scriptum: you can make Tempe with a variety of grains, not only soy.
