It is best not to eat sauerkraut in early pregnancy because it contains nitrite, which is not good for health. After pregnancy, the body’s resistance and immunity are low compared to normal people, so it is best not to eat sauerkraut. In addition, after pregnancy, in addition to strengthening nutrition, eat more fresh fruits or vegetables, but also to supplement sufficient protein, such as drinking milk, eating eggs, and eat more sea fish. Because sea fish contains a lot of lecithin, which can promote the development of the fetal brain, so eat more will give birth to a smarter baby. In addition, after pregnancy, you should have regular maternity checkups and not be exposed to toxic and harmful gases or objects.
