Soybeans are one of the richest vegan sources of protein usually in 100gms of soybean we will get about 52% of the protein that is more than even eggs and chicken . Soybeans are easy to digest and are a good source of dietary fibers as well. Now coming to the topic, that does soy increases our estrogens level is total bullshit and these are just marketing techniques used by some supplements company to sell their products by spreading myths in the people.
The myth that soy causes a rise in estrogen levels was overhyped due to presence of phytoestrogen in it
Phytoestrogen:- phytoestrogen is made up of 2 words phyto which means plant-based and estrogens which means simply estrogenic compound. Now, these phytoestrogens are chemically similar to the estrogens which are present in the animal body. But these phytoestrogens are very weak as compare to the estrogen in the human body and due to this, they don't affect our hormones concentration when taken in large amounts as well.
Recently a study was conducted which was an animal-based (on mice) in which around 20mg/kg of bodyweight of isoflavones was given to them on daily basis and there was 35% decrease in the testosterone level of mice
but if we calculate this amount for a healthy human then the amount of isoflavone will be around 1700 mg/day which is an extreme number (around 50-60 glasses of soy milk)
to support this common-sense approach a study was conducted on human beings where 40 mg of isoflavones supplement was given to them which is again a very high amount and blood samples were taken and the results show that's there was no adverse effects on their hormones level rather their LDL levels were decreased so according to common sense and scientific studies, it is very, much clear that a person can easily take soy and even a large intake of soy will not affect the body hormones as well.
