Had a talk today with a guy who was sort of offended for some reason about me not eating animal products and lifting weight. He said I’d never get enough protein (never heard that one before!!!). Because lentils aren’t a thing in a world of steaks.
Anyway he said that you need at least 200 grams of protein each day when you lift but that’s of course nonsense. Not saying you shouldn’t do it, but you don’t need to either.
I’m averaging around 110-140 grams a day and I’m doing fine at ±80kg body weight.
No, soy is not detrimental in healthy moderation. The amount of soy you would need to eat to effect your test would have to number in the tens of thousands of calories.
It’s a byproduct of the scare campaigns related to phytoestrogen in soy which has absolutely no effect on the human body whatsoever.
It’s a fad that people have against soy. Some people say it makes you more feminine or even go as far as to say you will grow boobs as a guy. But after years of consuming soy on a regular basis, I am yet to grow boobies.
People with no understand of science saw the word “Estrogen” and the far-right went buck wild with it. If photoestrogens made you grow boobies, the entire male population would be transfem. It is impossible to avoid soy in the modern world, and our ancestors have been eating it for thousands of years without a problem.
Far-right broscientists definitely went wild with the manboobs and feminine claims, however it is fair enough that these studies be read and understood. These are peer reviewed and researched studies.

also even if you ate actual estrogen, loads of it would be filtered out by a first pass through the liver. it’s not bioavailable by the oral route because it’s something the body can recognize as something that it shouldn’t get from food.
and soy phytoestrogens are more likely to act as estrogen blockers than estrogens, though the effect is very weak.
