Drinking black beans and soybean milk during pregnancy helps ovulation. You can drink it every day, but in moderation, so as not to increase the burden on the kidneys.

Black beans contain an ingredient called isoflavone, which is a kind of flavonoids and mainly exists in leguminous plants. It is similar to female estrogen in structure and is called "phytoestrogen".

The main function of female estrogen is to increase the thickness of endometrium, stimulate the development of follicles, promote the development of fallopian tubes and create favorable conditions for the entry of sperm. Therefore, eating black beans can really help promote ovulation. The same is true of black soybean milk.

However, black beans are not used to help ovulation in clinic. From a nutritional point of view, black beans contain estrogen, and pregnant women can really supplement estrogen. But in the process of pregnancy, not only estrogen, but too much estrogen is not enough. Therefore, although black beans are good, you should not eat more, nor drink more black beans and soy milk, so as not to increase the burden on the kidneys.
