In this era of information, we can often see such a saying: Eat more beans during pregnancy, especially black beans, which can help pregnancy and increase ovulation.My clinic often has patients who will ask "Is this true?"In the heart of a research, we said today that whether to eat beans can promote pregnancy.
First of all, it is necessary to understand the effective ingredients in beans -soybean isoflavones. This is a type of secondary metabolites formed in the growth of soybeans. It is a biological activity substance.Because it is extracted from plants and has a similar structure to estrogen, soy isoflavones are also called plant estrogen.Studies have shown that soy isoflavones have the effects of affecting hormone secretion, metabolic biological activity, protein synthesis, and growth factors activity.The role of soy isoflavones should be the root cause of "eating more beans can help pregnancy".
There are not a few people who have doubts about this problem. There are very little about modern medicine about the relationship between the two, so many scientists have done related research.In 2014, Bjarne and other scholars studied the relationship between plant estrogen intake and women’s reproductive abilities, and investigated the relationship between soybean isoflavones and the possibility of pregnancy.This research is mainly carried out among vegetarians, because their soy isoflavones are higher than other people.
This study found that when the ingestion of soy isoflavones exceeded about 40 mg per day, the overall risk of never pregnancy increased by 13%, and the probability of once lived was reduced by about 3%.This impact is even more significant in women who have difficulty in pregnancy (more than 1 year or more unsuccessful pregnancy).The close relationship between the proportion of soy isoflavones and the proportion of women in difficulty in pregnancy indicates that soybean isoflavones have indeed biological effects. High -dose soy isoflavones intake may cause extension of menstrual cycle and promote uterine fibroids. Instead in the uterusThe dedication of abnormal membrane growth may hinder fertility.
This research also conducted a survey of increasing the intake of soy products for women preparing for pregnant women to increase fertility.The results showed that among women aged 30-40 and women aged 41-50, soy isoflavones have nothing to do with the proportion of women’s pregnancy.In other words, increasing soy products intake can not be established.What is more interesting is that at the end of this study, the researchers called for further research. It is best to be a forward -looking research, refute or confirm the results of their research, that is, soy isoflavones have a significant impact on fertility.
After speaking women, let’s take a look at men.Pregnancy is not a matter of women alone. Male factors account for about 60 % of the cause of infertility.Soy isoflavones in daily dietary intake are related to the abnormal quality of semen and the level of male hormones.However, its impact on husband and wife’s fertility is still unclear.
Some people have conducted research on this issue. Couples who are treated with infertility in the reproductive center are the research objects. The couple of the research team are required to eat at least 15 foods per day in 3 months. These 15 kinds of foodIncluding tofu, tempeh, soy sausage, soybean burger, soybean buns, miso soup, soy milk, soy yogurt, tofu, beans, bean nuts, bean protein beverages and beans.Finally, the fertilization rate, embryo implantation rate, pregnancy rate and live production rate were compared.The results show that women and men consume soybean foods, and soy isoflavones have nothing to do with fertility ending.
Men can eat soy food twice or more, less than 41 × 106 /ml than men who do not eat soy foods, and the intake of soy food has nothing to do with sperm vitality, shape, or ejaculation.The data between plant estrogen and male reproductive capabilities are still very small, and additional research is needed to illustrate its role in human reproduction.
Male friends, sperm quality depends on themselves. Instead of eating more beans, it is better to exercise more, maintain a healthy lifestyle, do not smoke, and drink less.
In the end, let’s make a summary: The saying that eating more beans can be pregnant. At present, it is not very reliable. Don’t superstitious drinking soymilk. Eating black beans can promote pregnancy!There is no need to supplement the commercially available soy isoflavones health products.Of course, from the perspective of nutrition, there are still many beans that appropriately consume high protein and low -fat during pregnancy, and there is no problem as part of daily diet.
