Pregnant women can eat sweet potatoes in the first trimester and should not eat too much. Sweet potato is rich in vitamin C and trace elements, which is beneficial to fetal growth and development. Sweet potato contains a lot of dietary fiber, which can promote defecation.

Excessive progesterone secretion in pregnant women will inhibit gastrointestinal peristalsis and lead to constipation. Eating more foods containing more cellulose is helpful for defecation.

Sweet potatoes should not be eaten, especially in the second and third trimester of pregnancy. Sweet potato contains more sugar and starch, which will increase the blood sugar of pregnant women and lead to gestational diabetes. Without gestational diabetes, the fetus will be too big or even huge, which will increase the risk of dystocia and cesarean section. The effect of promoting fetal growth is particularly obvious in the second and third trimester, but not particularly obvious in the first trimester.
