Are bean products good or bad for breast diseases?
people eat whole grains, how can they not get sick? For women, breast diseases and gynecological diseases are the most common diseases. If women are in a state of accumulation of estrogen for a long time, it is possible to change breast diseases, such as mammary gland duct hyperplasia and even breast cancer.
It is undeniable that soy products, such as soybeans, all contain isoflavones, which have estrogen-like effects. That is to say, isoflavones are similar in molecular structure and function to estrogen secreted by human body, and can combine with estrogen receptors on cells to play the same role as estrogen [1].
But is it true that eating more soy products containing isoflavones will accelerate the occurrence of breast diseases? Actually, this is not the case at all:
First of all, the activity of this plant-derived estrogen is very weak, even if the intake is 1 times the amount of estrogen secreted by the human body itself, the activity is only one thousandth or even one ten thousandth of it, which belongs to weak estrogen [2]. However, because of its existence, it can competitively interfere with the combination of estrogen expressed by itself and its receptor, and the result is that although estrogen is abundant and active in the body, it makes you unable to play its role. Therefore, in the case of increased endogenous estrogen, eating soy products will not only accelerate the occurrence of breast diseases, but also inhibit them more or less.
Secondly, it has been reported that phytoestrogens can also reduce the level of endogenous ovarian steroids, thus reducing the occurrence of breast cancer [3]. It can also exert anti-cancer activity by inducing apoptosis and inhibiting gene or non-gene mechanisms such as tyrosine kinase and topoisomerase [4].
Therefore, it is not only beneficial for people with breast diseases to eat soy products, but also beneficial for normal healthy people to eat soy products properly. Special attention:
If you have breast diseases, kidney diseases, gout, etc. at the same time, you should eat less soy products. References:
