What should pregnant women eat to protect their fetus?

　　In modern medicine, "pregnancy protection" means preventing spontaneous abortion. According to statistics, the vast majority of spontaneous abortions occur in the first 13 weeks of pregnancy. Physiologically, it is not entirely clear why people miscarry spontaneously. In most cases, spontaneous abortion is followed by fetus associated with chromosomal abnormalities. Chromosomes are the carriers of genetic material, and chromosomal abnormalities mean that the fetus has genetic defects. Once this defect occurs, it cannot be changed by what the mother eats. In other words, for spontaneous abortion caused by chromosomal abnormalities, which is the most common cause of spontaneous abortion, there are currently no effective measures to solve it, and eating bird's nest is naturally useless.

　　Other common factors associated with spontaneous abortion include hormones, infection, smoking, drug reactions, and excessive drinking. coffee , radiation, exposure to toxic substances, etc. Advanced maternal age and severe psychological trauma also increase the risk of spontaneous transmission. Exactly how these factors increase the risk of miscarriage is unclear. However, eating bird's nest will not reduce the impact of these factors, and it will not have a "pregnancy protection" effect on miscarriage caused by these factors.

　　Maternal malnutrition can also increase the risk of miscarriage. Many people also take bird's nest as a "holy nutritional product". Not to mention that people who can afford bird's nests cannot be "malnourished" at all. From a nutritional point of view, bird's nests are really lackluster. Any nutrients one can find in bird's nests can be obtained, or even superior, through other common foods. For example, protein, bird’s nest is not as good as egg Milk "high quality". Of course, people who believe that bird's nest has "super nutrition" are always willing to believe that it contains "magic ingredients" that have not been discovered by modern science - but this is just like we can "believe" that there is Sun Wukong on the Flower and Fruit Mountain, it is only logically possible.

　　Giving birth to a new life is undoubtedly a major event in life for young parents. We tend to be willing to do anything that “might be useful” for their birth. However, bird's nest is just an exchange of money for a little psychological comfort - if you understand that bird's nest has no "pregnancy protection" effect, you can use the money in more meaningful ways for your child. The psychological satisfaction obtained in this way has the same "pregnancy protection" effect as the psychological comfort brought by eating bird's nest.

　　According to the recommendations of modern science, pregnant women can pay attention to the following things to "preserve miscarriage": avoid confrontational exercise, but maintain an appropriate amount of regular physical activity； balanced healthy diet； keep a happy mood ； maintain a reasonable weight ； folic acid supplement ； Avoid alcohol and tobacco ； Consult your doctor before taking any medication etc.
