It is better to drink some soy milk in the third trimester, because the nutrition in soy milk is also rich. Drinking soy milk in moderation is not only good for pregnant women's own health, but also good for the development of the fetus, and the ingredients contained in soy milk can also regulate the endocrine system of pregnant women. But there is no need to drink it every night, which will easily cause irritation and damage to the gastrointestinal system and abdominal distension and pain.
